Wood Stove Changeout Clears the Air in Libby, Montana
U.S. EPA Declares Libby Area Air Quality Meets Fine Particle Standard
Arlington, VA (October 13, 2009) - The Hearth, Patio & Barbecue Association (HPBA) is excited to announce the final success of the Libby, Montana, wood stove changeout program. This effort led by HPBA, the U.S. EPA and Montana state and local officials replaced 1130 outdated wood-burning appliances with new cleaner burning EPA-certified wood stoves donated and installed by HPBA member companies.
Prior to the changeout, the Lincoln County town of Libby was predicted to fall short of meeting the new 24-hour fine particulate matter (PM2.5) federal standard according to state-validated air quality monitoring data for the three years, 2005 through 2007. However, data for the most recent three years - 2006, 2007 and 2008 - proved the area was meeting the standard. It is now an official attainment area.
"These results show that new technology wood-burning stoves, fireplace inserts and pellet stoves have a positive affect on the environment - both outdoors and in," said Jack Goldman, president of HPBA. "Not only do they burn cleaner than old-model stoves, they burn far more efficiently and use one-third less wood to heat the same space than previous stoves. This is great news for the people in Libby. They can now continue to warm their homes safely with wood, their main fuel source for home heating."
According to U.S. EPA, PM2.5 is a by-product of fuel combustion from wood burning, gasoline automobiles, diesel-powered vehicles such as trucks and busses, power plants and industrial processes and has been associated with a variety of serious health problems including heart attacks, chronic bronchitis and asthma. By removing old technology wood-burning stoves and replacing them with new clean-burning stoves, residents of Libby, MT, are breathing easier.
Consumers interested in clean-burning wood- or pellet-burning appliances can now receive a federal tax credit for up to $1,500 on the purchase and installation of a 75% efficient appliance. For information on clean-burning wood stoves and the federal 30%/$1500 consumer tax credit for wood and pellet burning stoves, go to www.hpba.org/taxcredit.

If you didn't change oil on your car it will still keep working for a long time. You may be able to drive 30, 40, maybe 60,000 miles without changing your oil. But the efficiency will go down, you will waste fuel, and the motor will definitly fail earlier than it should. Same goes for your furnace. If you never have a profesional HVAC company clean and inspect your furnace you will waste money on your heating bills and it will also fail early. Could you imagine living in Minnesota and going on vacation for a week in January when the average temperature is about 15 degrees and night can be -15 to -30 degrees and your furnace fails. Well it happens every day. If you lose heat in your home and you are away you could freeze the water pipes and flood your home.
Is freezing pipes worst case senoiro? Or is having a gas leak, carbon monoxide poisioning, or cold house with a 6 month old baby. All of these are bad and happen very commonly. But the most common problem by not having your furnace profesionally tuned up is wasting money every month on your gas bill and having to buy a new furnace 5-7 years earlier than needed.
Lets play some numbers. Pretend running an unefficient furnace waste $15/month. 6 month heating season equals $90/year. Next if a new furance install cost $3,500 and should last 20 years but now only last 12 years. That is like wasting another $116/year. So total waste is $206/year. That is $2,060 over 10 years. Well you can have a HVAC company do a quality inspection and cleaning for less money than $206/year typically.
So having a furnace tune up annually can save you money, drastically reduce chance of break down, save money on service, and provide a safer home for your family.

The U.S. government established a mandatory compliance program in the 1970s requiring that certain types of new appliances bear a label to help consumers compare the energy efficiency among similar products. In 1980, the Federal Trade Commission's Appliance Labeling Rule became effective, and requires that EnergyGuide labels be placed on all new refrigerators, freezers, water heaters, dishwashers, clothes washers, room air conditioners, heat pumps, furnaces, and boilers. These labels are bright yellow with black lettering identifying energy consumption characteristics of household appliances. Although these labels will not tell you which appliance is the most efficient, they will tell you the annual energy consumption and operating cost for each appliance so you can compare them yourself.
EnergyGuide labels show the estimated yearly electricity consumption to operate the product along with a scale for comparison among similar products. The comparison scale shows the least and most energy used by comparable models. The labeled model is represented by an arrow pointing to its relative position on that scale. This allows consumers to compare the labeled model with other similar models. The consumption figure printed on EnergyGuide labels, in kilowatt-hours (kWh), is based on average usage assumptions and your actual energy consumption may vary depending on the appliance usage.EnergyGuide labels are not required on kitchen ranges, microwave ovens, clothes dryers, on-demand water heaters, portable space heaters, and lights.

Why is it important?
What does it mean to me?
How do I know if a technician is NATE certified?
People want their comfort systems fixed fast, fixed right, and fixed the first time. But how do you pre-judge the quality of service you will receive?
No matter how reputable the company is that you call for service, the quality of your experience is ultimately dependent upon the quality of the technician dispatched to your home. How do you know whether a company employs qualified technicians?
One way is NATE certification.
A Few Facts
NATE is the North American Technician Excellence™ program. Modeled after the ASE certification program in the automotive industry, NATE is the industry standard for technician certification.
NATE is the industry’s national certification program and is supported by the entire industry.
Broad national surveys indicate that consumers overwhelmingly desire certified technicians. In fact, seven out of eight homeowners want their equipment serviced by a nationally certified technician.
NATE certification is far from certain, even for experienced technician. Nationally, passing rates for NATE certification exams are about the same as passing rates for the “bar” to earn a license to practice law.
Why is NATE Certification important?
Heating and air conditioning equipment gets more sophisticated with each passing year. Many of today’s comfort products include computer control boards and high tech sensor systems. Installing and servicing equipment requires more in-depth knowledge and training than ever before. NATE certification was designed to reflect a consensus of the knowledge industry experts determined technicians needed to be able to install and service equipment properly.
Should I allow a technician without NATE Certification to work on my comfort system?
NATE certification is voluntary and many excellent technicians have yet to sit for the NATE exams. In other words, there are good technicians who are not NATE certified. However, the odds of finding a good, qualified, competent technician increases when you insist on NATE certification. NATE certification means the technician is well-grounded in the knowledge he or she needs. NATE certification also reflects a commitment by the technician to the heating and air conditioning industry as a profession. NATE certified technicians are serious about their craft and self-motivated to perform well.
How do I know if a technician is NATE Certified?
For starters, ask for a NATE certified technician when you call for service. Beyond requesting one, identifying a NATE certified technician is often as simple as looking for the NATE patch on the sleeve of their uniform. If you unsure, ask the technician if he or she is NATE certified. NATE also maintains a database of contractors employing NATE certified technicians at www.natex.org.

Why is mold growing in my home?
Molds are part of the natural environment. Outdoors, molds play a part in nature by breaking down dead organic matter such as fallen leaves and dead trees, but indoors, mold growth should be avoided. Molds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air. Mold may begin growing indoors when mold spores land on surfaces that are wet. There are many types of mold, and none of them will grow without water or moisture.
Can mold cause health problems?
Molds are usually not a problem indoors, unless mold spores land on a wet or damp spot and begin growing. Molds have the potential to cause health problems. Molds produce allergens (substances that can cause allergic reactions), irritants, and in some cases, potentially toxic substances (mycotoxins). Inhaling or touching mold or mold spores may cause allergic reactions in sensitive individuals. Allergic responses include hay fever-type symptoms, such as sneezing, runny nose, red eyes, and skin rash (dermatitis). Allergic reactions to mold are common. They can be immediate or delayed. Molds can also cause asthma attacks in people with asthma who are allergic to mold. In addition, mold exposure can irritate the eyes, skin, nose, throat, and lungs of both mold-allergic and non-allergic people. Symptoms other than the allergic and irritant types are not commonly reported as a result of inhaling mold. Research on mold and health effects is ongoing. This brochure provides a brief overview; it does not describe all potential health effects related to mold exposure. For more detailed information consult a health professional. You may also wish to consult your state or local health department.
How do I get rid of mold?
It is impossible to get rid of all mold and mold spores indoors; some mold spores will be found floating through the air and in house dust. The mold spores will not grow if moisture is not present. Indoor mold growth can and should be prevented or controlled by controlling moisture indoors. If there is mold growth in your home, you must clean up the mold and fix the water problem. If you clean up the mold, but don't fix the water problem, then, most likely, the mold problem will come back.
Who should do the cleanup?
Who should do the cleanup depends on a number of factors. One consideration is the size of the mold problem. If the moldy area is less than about 10 square feet (less than roughly a 3 ft. by 3 ft. patch), in most cases, you can handle the job yourself, following the guidelines below. However:
- If there has been a lot of water damage, and/or mold growth covers more than 10 square feet, consult the U.S. Environmental Protection Agency (EPA) guide: Mold Remediation in Schools and Commercial Buildings. Although focused on schools and commercial buildings, this document is applicable to other building types. It is available free by calling the EPA Indoor Air Quality Information Clearinghouse at (800) 438-4318, or on the Internet at epa.gov/iaq/molds/mold_remediation.html.
- If you choose to hire a contractor (or other professional service provider) to do the cleanup, make sure the contractor has experience cleaning up mold. Check references and ask the contractor to follow the recommendations in EPA's Mold Remediation in Schools and Commercial Buildings, the guidelines of the American Conference of Governmental Industrial Hygenists (ACGIH), or other guidelines from professional or government organizations.
- If you suspect that the heating/ventilation/air conditioning (HVAC) system may be contaminated with mold (it is part of an identified moisture problem, for instance, or there is mold near the intake to the system), consult EPA's guide Should You Have the Air Ducts in Your Home Cleaned? before taking further action. Do not run the HVAC system if you know or suspect that it is contaminated with mold - it could spread mold throughout the building. Visit epa.gov/iaq/pubs/airduct.html, or call (800) 438-4318 for a free copy.
- If the water and/or mold damage was caused by sewage or other contaminated water, then call in a professional who has experience cleaning and fixing buildings damaged by contaminated water.
- If you have health concerns, consult a health professional before starting cleanup.
Tips and techniques
The tips and techniques presented in this section will help you clean up your mold problem. Professional cleaners or remediators may use methods not covered in this publication. Please note that mold may cause staining and cosmetic damage. It may not be possible to clean an item so that its original appearance is restored.
- Fix plumbing leaks and other water problems as soon as possible. Dry all items completely.
- Scrub mold off hard surfaces with detergent and water, and dry completely.
- Absorbent or porous materials, such as ceiling tiles and carpet, may have to be thrown away if they become moldy. Mold can grow on or fill in the empty spaces and crevices of porous materials, so the mold may be difficult or impossible to remove completely.
- Avoid exposing yourself or others to mold (see discussions: What to Wear When Cleaning Moldy Areas and Hidden Mold).
- Do not paint or caulk moldy surfaces. Clean up the mold and dry the surfaces before painting. Paint applied over moldy surfaces is likely to peel.
- If you are unsure about how to clean an item, or if the item is expensive or of sentimental value, you may wish to consult a specialist. Specialists in furniture repair, restoration, painting, art restoration and conservation, carpet and rug cleaning, water damage, and fire or water restoration are commonly listed in phone books.
Be sure to ask for and check references. Look for specialists who are affiliated with professional organizations.
- Avoid breathing in mold or mold spores. In order to limit your exposure to airborne mold, you may want to wear an N-95 respirator, available at many hardware stores and from companies that advertise on the Internet. (They cost about $12 to $25.) Some N-95 respirators resemble a paper dust mask with a nozzle on the front, others are made primarily of plastic or rubber and have removable cartridges that trap most of the mold spores from entering. In order to be effective, the respirator or mask must fit properly, so carefully follow the instructions supplied with the respirator. Please note that the Occupational Safety and Health Administration (OSHA) requires that respirators fit properly (fit testing) when used in an occupational setting; consult OSHA for more information (800-321-OSHA or osha.gov/ ).
- Wear gloves. Long gloves that extend to the middle of the forearm are recommended. When working with water and a mild detergent, ordinary household rubber gloves may be used. If you are using a disinfectant, a biocide such as chlorine bleach, or a strong cleaning solution, you should select gloves made from natural rubber, neoprene, nitrile, polyurethane, or PVC (see Cleanup and Biocides). Avoid touching mold or moldy items with your bare hands.
- Wear goggles. Goggles that do not have ventilation holes are recommended. Avoid getting mold or mold spores in your eyes.
How Do I Know When the Remediation or Cleanup is Finished?
You must have completely fixed the water or moisture problem before the cleanup or remediation can be considered finished.
- You should have completed mold removal. Visible mold and moldy odors should not be present. Please note that mold may cause staining and cosmetic damage
- You should have revisited the site(s) shortly after cleanup and it should show no signs of water damage or mold growth.
- People should have been able to occupy or re-occupy the area without health complaints or physical symptoms.
- Ultimately, this is a judgment call; there is no easy answer. If you have concerns or questions call the EPA Indoor Air Quality Information Clearinghouse at (800) 438-4318.
- Moisture control is the key to mold control, so when water leaks or spills occur indoors - ACT QUICKLY. If wet or damp materials or areas are dried 24-48 hours after a leak or spill happens, in most cases mold will not grow.
- Clean and repair roof gutters regularly.
- Make sure the ground slopes away from the building foundation, so that water does not enter or collect around the foundation.
- Keep air conditioning drip pans clean and the drain lines unobstructed and flowing properly.
- Keep indoor humidity low. If possible, keep indoor humidity below 60 percent (ideally between 30 and 50 percent) relative humidity. Relative humidity can be measured with a moisture or humidity meter, a small, inexpensive ($10-$50) instrument available at many hardware stores.
- If you see condensation or moisture collecting on windows, walls or pipes ACT QUICKLY to dry the wet surface and reduce the moisture/water source. Condensation can be a sign of high humidity.
Actions that will help to reduce humidity:
- Vent appliances that produce moisture, such as clothes dryers, stoves, and kerosene heaters to the outside where possible. (Combustion appliances such as stoves and kerosene heaters produce water vapor and will increase the humidity unless vented to the outside.)
- Use air conditioners and/or de-humidifiers when needed.
Run the bathroom fan or open the window when showering. Use exhaust fans or open windows whenever cooking, running the dishwasher or dishwashing, etc. Actions that will help prevent condensation: Is sampling for mold needed? In most cases, if visible mold growth is present, sampling is unnecessary. Since no EPA or other federal limits have been set for mold or mold spores, sampling cannot be used to check a building's compliance with federal mold standards. Surface sampling may be useful to determine if an area has been adequately cleaned or remediated. Sampling for mold should be conducted by professionals who have specific experience in designing mold sampling protocols, sampling methods, and interpreting results. Sample analysis should follow analytical methods recommended by the American Industrial Hygiene Association (AIHA), the American Conference of Governmental Industrial Hygienists (ACGIH), or other professional organizations.
Testing or Sampling for Mold
Actions that will help prevent condensation:
Is sampling for mold needed? In most cases, if visible mold growth is present, sampling is unnecessary. Since no EPA or other federal limits have been set for mold or mold spores, sampling cannot be used to check a building's compliance with federal mold standards.

Sample analysis should follow analytical methods recommended by the American Industrial Hygiene Association (AIHA), the American Conference of Governmental Industrial Hygienists (ACGIH), or other professional organizations.
Suspicion of Hidden Mold
You may suspect hidden mold if a building smells moldy, but you cannot see the source, or if you know there has been water damage and residents are reporting health problems. Mold may be hidden in places such as the back side of dry wall, wallpaper, or paneling, the top side of ceiling tiles, the underside of carpets and pads, etc. Other possible locations of hidden mold include areas inside walls around pipes (with leaking or condensing pipes), the surface of walls behind furniture (where condensation forms), inside ductwork, and in roof materials above ceiling tiles (due to roof leaks or insufficient insulation).
Investigating hidden mold problems
Investigating hidden mold problems may be difficult and will require caution when the investigation involves disturbing potential sites of mold growth. For example, removal of wallpaper can lead to a massive release of spores if there is mold growing on the underside of the paper. If you believe that you may have a hidden mold problem, consider hiring an experienced professional.
Cleanup and Biocides
Biocides are substances that can destroy living organisms. The use of a chemical or biocide that kills organisms such as mold (chlorine bleach, for example) is not recommended as a routine practice during mold cleanup. There may be instances, however, when professional judgment may indicate its use (for example, when immune-compromised individuals are present). In most cases, it is not possible or desirable to sterilize an area; a background level of mold spores will remain - these spores will not grow if the moisture problem has been resolved. If you choose to use disinfectants or biocides, always ventilate the area and exhaust the air to the outdoors. Never mix chlorine bleach solution with other cleaning solutions or detergents that contain ammonia because toxic fumes could be produced.
Please note: Dead mold may still cause allergic reactions in some people, so it is not enough to simply kill the mold, it must also be removed.
For more information on mold related issues including mold cleanup and moisture control/condensation/humidity issues, you can call the EPA Indoor Air Quality Information Clearinghouse at (800) 438-4318.

Oh no... Summer's almost over? Not yet, the Minnesota State Fair is typically a hot and busy week. Comfort Matters Heating and Cooling, Inc was able to help keep one of the food stands cold.
Midway Food Company from Winchester, Texas area has a food stand called the Midway Grill and it gets pretty hot working over a grill at the fair. Well only a couple weeks away their air conditioning stopped working on their custom built portable 18,000 pound kitchen. The trailer was out in Montana at a fair when Comfort Matters got the call that they were heading to Minnesota for the fair and needed to get the cooling fixed. Comfort Matters found a Trane rooftop air conditioner in Laramie Wyoming that would work. So within days before the fair the trailer was delivered to Comfort Matters office in Hanover, MN.
"This became a very interesting and custom installation" said Corey Hickmann (owner of Comfort Matters Heating and Cooling, Inc.) We brought in Crystal Welding to help custom build the aluminum frame and ducting so we could mount the new Trane unit on the Roof. Even though it decided to rain most of the day slowing down the work, the new cooling system was up and running the next day and ready for delivery to the fair. The Minnesota State Fair is the largest fair in the country for daily attendance and it is very important to the Midway Grill to have a successful event.
So if you are out at the fair try a burger and fries at the Midway Grill, and if you miss it there it will be heading to Utah, Texas, and a few other stops before the year is over.

- Check references: I can not stress this enough. If you are spending $2500 or $10,000 you must check the contractor references. A new furnace or a/c should last 20 years. But even more important is in Minnesota for example you will spend $26,000 over those 20 years on average to heat and cool your home. So ask for testimonials. If the contractor surveys there customers ask to see the surveys. If you want to make the best choice ask to talk to customer they have done work for. Make sure they will call you back on Saturday when it is -20 or 95 degrees outside if your heating or cooling doesn't work.
- Ask for copy of liability insurance certificate: Check to see what there coverage is. You want at minimum $1 million dollars coverage. Then if you really want to be safe call there insurance company to confirm there premiums are paid in full. To many companies can show a certificate but may not be late on payments. If something happens you the homeowner are responsible. If the contractor is not willing to give you this info "walk away".
- Confirm they have a current State Bond: In Minnesota for example contractors are required to have a state bond to help protect the homeowner in case the contractor goes out of business.
- Get Permits: Ask for copy of the local permit at time of installation. Note: some cities do not require permits so you can't in those cases. But call your city hall to confirm that is true.
- Back ground screened employees: Does the company criminally screen there employees. The people installing your new furnace or A/C have access to your home, make sure they are safe.
- Does the company work from home: Confirm they actually work from a office. Some contractors may office from home and do great work. But the majority of bad contractors also work from home. Don't base decision on this but it will help.
Don't worry about the brand of furnace or A/C you buy. If it is a Carrier, Goodman, Amana, Trane, Bryant, Chevy, Ford, or BMW it does not matter as much as who installs it. What matters is how well trained the installers are, will they be there for you if it fails, and will it save you money on your energy bills for the next 2 or 20 years. (BTW: no Chevy, Ford, or BMW don't make furnace and A/C)
The upfront cost of the installation will be determined by factors I listed above. Just because someone offers a lower installation you are not saving money. I have learned that lesson over the years. When the cost is lower the odds say something is missing.

Will a 2-stage gas furnace save me money?
Well this is kind of a loaded question. For example I am going to use a 95% efficient gas furnace. The brand does not matter. If you buy a Trane, Bryant, Carrier, Goodman, or Lennox there is not a measurable amount of difference. The bigger difference will be by what company installs it. Majority of furnaces installed are 1-stage. Which means when the house gets cold 100% of the heat comes on. The problem is if it isn't very cold out the furnace may only run for 5 or 10 minutes then shut off. A furnace needs to run at least 10 minutes before you can even get it up to 95% efficient. When if first comes on it will be maybe 50%, then 60%, and keep going up as it runs longer until it reaches peak efficiency. It is like a car, if you drive stop and go traffic your gas mileage is low, but if you go on the highway for 60 miles and don't stop your gas mileage goes up.
So if your furnace turns on and off to often you will not ever get to save money because the furnace doesn't get to peak efficiency. So back to the installing company. If they install a furnace that is to large for your home it will turn on and off to many times during the day cost you money and making your gas company lots of money. So a very common problem is if the installing company selects a furnace that is to large it will run on low stage to often wasting energy. So it is possible to put in a new more efficient furnace but have it not save you any money.
Today we have 1-stage, 2-stage, 3-stage, and modulating furnaces. The advantage of multi stage furnaces is better comfort in the home. If the furnace runs longer it will get the temperature more even in your rooms. Plus the longer the furnace runs and less on/off cycles reliability does go up. So multi stage may help the furnace last longer which will save you money. But you may not be saving what you should be. Depending on model's the first stage (low heat) could be only 70-85% efficient, compared to high heat when it could be 95% efficient. A properly installed 1-stage or multi stage furnace will give you far better long term results. As time goes on gas will keep going up. A well installed furnace could last your 15-20 years. So why over pay each month on your gas bill. Be very careful on selecting your installing contractor because that can save you $1,000's of dollars over the next 15-20 years.
So the moral of the story is "just because your new furnace is 2-STAGE, that does not mean it will save you more money".

The big difference with air source heat pump is they can't provide enough heat from the home once outdoor temp gets below 20 degrees. So you need some sort of extra heat whether it be natural gas, oil, LP, or electric heat. Geothermal systems can be designed to heat your home to what ever outdoor temp you want.
Here is the catch to be careful of. If you are converting your current heating system to geothermal the duct work was designed for something else. For example purpose I am going to compare an average gas or oil heat. Now electric heat system won't be much different.
EXAMPLES BELOW ARE FOR A MINNESOTA HOME
Gas heat systems can provide higher temperature heat in the duct system with less air flow. So when a home is designed for gas the average home needs 1000-1400 CFM. (CFM= cubic feet per minute of air) A home that has a duct system for 1000 CFM with gas heat may now need a 4 ton geothermal heating system. Average design is 400 CFM/ton of geo. So a 4ton geo will need 1600 CFM. The problem is over 50% of home duct systems are undersized in the first place. An educated HVAC company will be able to test your home and see what you can do. Below is a typical solution that way to many heating companies do wrong.
Home needs a 4ton geo which is 1600 CFM but home has duct system only good enough for 1000 CFM. A common answer is to select a 3 ton geo system with gas back up heat. The 3 ton geo will need 1200 CFm. Usually some minor modification can be made to the duct system to handle 1200 CFM. Now when you get to the dead of winter in January when it is -10 and colder for a week straight the geo may not be able to keep up so you will need to use the gas furnace a little. But by going from a 4ton to a 3ton geo you will save about $2,500 just in well drilling. Plus you don't have to tear your home apart making the duct system large enough for a 4ton system. So by going to a 3ton you may save $3500, 4000, maybe 5000. Yes the 3ton may cost an extra $200 per year to heat your home, but it could take you 20 years to equal the $4000 savings.
So in short you maybe able to install a 3ton geo and have a 10 year pay back or a 4ton geo and have a 30 year pay back.
Now these examples above are very general and will vary by area you live or type of home. Point to be aware of bigger definitely is not better when it comes to geo. Now with the 30% federal tax credit geo is cheaper than ever to install and pay back is a lot faster. But don't let a poorly educated installation company steer you the wrong way.

The Post-it note is known as a great American invention. Back in 1974 Arthur Fry came up with way to make an experimental glue famous while working for 3M in Minnesota. The Post-it note changed the world of paper. So as I was thinking about this I wondered what major innovation changed the way we heat and cool a home. There are many things that have changed the comfort we feel in a home today.
Early years we had a fireplace in our 1-room house. Now the average home has 2-3 bathrooms. In the early 1900's when coal fired furnaces were used a house could vary in temp 30-40 degrees easily depending on what room you were in because once you got the coal burning hot you couldn't just stop it.
Today people expect to be comfortable when they sleep, keep the babies room warm in the winter, but still save energy. Zoned Heating has been the technology that has allowed this. The average home has one thermostat in the hallway which tells the furnace to turn on or off. First who lives in the hallway, so why do we care what the temperature is there. Imagine if you only had one light switch in your whole house. Well that is what happens when you have one thermostat. Two story homes are a real problem because in the summer the upper level is hot and the basement is cold. The other advantage of zone systems is why do you want to cool your bedrooms to 74 degrees during the day when no one is in there. Or why do you want your living room to be cooled at 3 AM when you are in bed.
Zone systems allow a standard home to have multiple thermostats through out the house. So you can cool the bedrooms at night, but not waste energy cooling the living room. Or in the winter you can heat your basement over 65 degrees unlike the average home. People commonly spend well over $20k finishing a basement to use but then they freeze trying to watch TV down there. To get a better understanding how it works click HERE to see a short video.
Honeywell says you can see up to 30% savings on your heating and cooling bills by zoning your home. One major energy savings people experience, is in the summer. Homeowners will set there thermostat to 70-72 degrees on the main level so they can hopefully get the upstairs to 76-78. When you have zoning in your home you have a thermostat upstairs in your master bedroom for example and you set that thermostat to 75 degrees and you can leave the living room at 78 for example while you sleep.
One thing you have to be concerned about is the installation of a zone system is who is the company designing and installing it. It is important to research who you buy a zone system from because if it is improperly installed you can shorten the life of your furnace and A/C and have a noisy operating system. But a properly installed zone system is like a "Post-It Note" to me.

Manufactures have made major changes to warranties over the years. Plus there are many untold parts also.
First thing what is covered. Well there is 3 major components to the warranty.
- Parts, this includes the little things like contactors, capacitors, and fan motors.
- Compressor, this is the most expensive and important part of the unit. This is the main work horse, kind of like the engine in a car. Typical compressor replacement is $1,200-1,900.
- Labor, this is the thing a lot of contractors miss lead to homeowners. Pretty much every manufacture of a/c units require the contractor to cover labor warranty on there own unless you purchase an extended warranty to cover labor. So becareful because if the contractor tells you 1 year, hope he is still in business then. Or are they the kind of company that will call you back when you have trouble. It is very common to see the low price contrctor also be the guy who won't return your call if your A/C stops working in 8 months.
2nd Major Issue:
Almost all brands use to be 1 Year parts Warranty. Now as compitition has grown they started to increase warranty. A very common warranty today now is 10 Years on all parts. BUT.... you must register the unit within 60-90 days or else your warranty drops to 5 years. The registered warranty is also only good for the original buyer, not the second owner of the home. Example Trane use to have 10 Year parts warranty on there XL systems. You didn't have to register it and if you sold the home the new buyer got the remander of the warranty. Now the same XL unit will only give the original buyer 10 years and it drops to 5 years if you don't register it.
Guess what, people forget to register things. That isn't a secret to anybody. The problem you will find is most contractors may leave that detail out. Some contractors actually will register the unit for there customers so it doesn't get forgot. This is one difference between a quality installing company and the cheap guy.
All this above is common to different brands. Weather you are buying TRANE, BRYANT, LENNOX, CARRIER, ARMSTRONG, YORK, LUXAIRE, HEIL, PAYNE, AMERICAN STANDARD, COMFORT MAKER, DAY NIGHT, GOODMAN, AMANA, FRIDGIDAIRE, MAYTAG, TAPPAN, KENMORE, TEMPSTAR, NORDYNE, or who ever they all are pretty much the same. Funny thing of the 20 brands I listed above that is actually only 6 different companys. Just like buying a Chevy, GMC, or Buick, same car just different stearing wheel.
Research your contractor before you worry about the warranty or brand.

Think about the 2nd story. There are 4 outside walls plus a roof. Most attics are 110-125 degrees on a hot summer day. That hot air wants to get into your home. Heat travels towards cold. Now when you only have one thermostat in the main level how does it know the bedrooms are hot? Duct systems are typically very poorly designed today and don't let enough cold air get to the up stairs.
So, now what do I do?
Well just add a second thermostat to the upper level. It isn't as easy as it sounds, but for a professional heating and cooling company it isn't that hard. They can add automatic dampers that will direct the cold air to the places in the home that need it. This allows you to keep you main level at a nice 75 degrees and your upstairs at 75. Or what ever temperature you like. The video on Arzel zoning does a nice job explaining it.
Arzel Zoning (may take a minute to load depending on your interent speed)
Accourding to Honeywell a typical home will save 20-25% on there heating and cooling bills by adding zoning to your home. Plus you can actually sleep good at night.
Oh, I almost forgot, if your basement is to cold in the winter, zoning can fix that also. Just another bonus.

Water Heating Tips
Repair leaky faucets promptly; a leaky faucet wastes gallons of water in a short period.
Insulate your electric hot-water storage tank and pipes, but be careful not to cover the thermostat.
Insulate your gas or oil hot-water storage tank and pipes, but be careful not to cover the water heater's top, bottom, thermostat, or burner compartment; when in doubt, get professional help.
Install non-aerating low-flow faucets and showerheads.
Buy a new water heater. While it may cost more initially than a standard water heater, the energy savings will continue during the lifetime of the appliance.
Although most water heaters last 10-15 years, it's best to start shopping for a new one if yours is more than 7 years old. Doing some research before your heater fails will enable you to select one that most appropriately meets your needs.
Lower the thermostat on your water heater; water heaters sometimes come from the factory with high temperature settings, but a setting of 115°F provides comfortable hot water for most uses.
Drain a quart of water from your water tank every 3 months to remove sediment that impedes heat transfer and lowers the efficiency of your heater. The type of water tank you have determines the steps to take, so follow the manufacturer's advice.
If you heat with electricity and live in a warm and sunny climate, consider installing a solar water heater. The solar units are environmentally friendly and can now be installed on your roof to blend with the architecture of your house.
- Take more showers than baths. Bathing uses the most hot water in the average household. You use 15-25 gallons of hot water for a bath, but less than 10 gallons during a 5-minute shower.

Four season porches are very popular in northern climate. When the summer comes the mosquitoes come with. So you can't sit outside with out bugs and bees bothering you. The spring is wet and fall is cool. Well winter, all of us in the Midwest know what winter is. You and all your neighbors hibernate in home. The problem heating and cooling a 4 season porch with your home heating/cooling system is difficult to get the proper amount of duct work in the room for good air flow. Mitsubishi ductless heating/cooling systems are a great choice. Our most popular model now qualifies for a 30% tax credit because it is so efficient. The new Mitsubishi 9,000 and 12,000 BTU models are up to 26 SEER. The typical home cooling system is 6-10 SEER. SEER is like gas millage, the higher it is the less money to run. Mitsubishi now has a feature called "eye see". Meaning the unit actually has an eye that looks at your room to see what temperature each spot is. The unit will then automatically blow air in that direction. Mitsubishi heat pump systems are great because they provide a very low cost heating. These units will run at 300% efficient on average. A typical heat pump usually can't supply enough heat on a good cold Minnesota day. So when it is -15 outside you may not be able to keep your porch at 70 degrees. But there are not many days that it is that cold. If you want perfect heat all year adding a fireplace is a great choice. Talk to your local heating professional for details.
It is hard to go wrong with ductless systems.
- More efficient because you don't have duct work to leak air
- Better technology
- Multi speed units adjust as the temperature gets hotter or colder
- Proven technology for over 25 years just in USA, longer world wide
- Easy to operate
- Low maintenance
