Heating and A/C will use about 60% of the energy in a home today. Commercial Buildings can be even worse. An easy way to do your part of "Being Green" is to start here. Today's technology now offers many ways to save energy while saving money on your gas and electric bills. Plus a properly installed and clean HVAC system will last much longer saving you money.
Now I have heard many stories trying to fix a furnace. But this would have to be the most difficult one I have heard. There are many reason's to be careful when repairing an appliance in your home.
HARTFORD, Conn. -- Jonathan Metz had been trapped for two days in his basement with his left arm stuck in a broken furnace. Smelling rotting flesh, he decided that amputation was his only hope.
So he fashioned a tourniquet near his shoulder and began cutting. He made it almost all the way through, but wasn't able to free himself.
There are many reasons you may have hot and cold rooms in your home. It is amazing that so many homes have the same problems, so don't feel like you are the only one. Everyday people tell me there upstairs is too hot or bedroom is too cold. Many times the repair is not major. An NCI Company can do some simple and quick tests to your home in about 60-90 minutes and see what is going on. Majority of the time the fix does not mean you have to buy a new furnace or A/C. Below is information provided by NATIONAL COMFORT INSTITUTE.
Four Reasons Why Your Home May be Uncomfortable If you asked a number of people to define a comfortable home they might say; a place with nice furniture, a place that is warm and dry, a place that has a lot of space. When we get a call from a customer who says their home is uncomfortable it usually means they are having problems controlling temperatures and humidity within the home.
1. Undersized or Oversized Furnace or Air Conditioner When someone designed your home, part of the design included the heating and cooling system. As with most homes, yours may have been modified since that original design. Or, if your home is new, the comfort system design may not be adequate for the home you are living in. We can evaluate the comfort and performance of your system based on the way your home is now. This includes any design changes, new insulation, windows, the addition of furniture, draperies, carpets and the hundreds of other items that can affect the way your comfort system performs.
For example, if your heating system isn't able to "keep up" on colder days, there's a good chance it's undersized. If it turns on and off constantly, chances are it's oversized. If your cooling system just won't cool your house down on the warmest days, there's a good chance it's undersized, or wasn't installed correctly. If it cycles on and off constantly and doesn't seem to pull the humidity out, it's likely oversized. This condition also wastes a great deal of energy and causes unnecessary wear and tear on your equipment.
2. Incorrect Duct System Most homes have a heating and cooling system that was designed for ideal scenarios. Unfortunately most homes are never ideal and often the air delivery systems do not work the way they were designed. In some cases, a duct system may be installed improperly or was damaged at some point so that it's not delivering the correct air into each room. This usually results in an uncomfortable home. Our technicians can check the airflow into each room and evaluate if your system is delivering the correct amount for the size of each room in your home.
3. Poor Air Quality The funny thing about air quality is that you can't always smell it, but you can often feel it, and it can be a major contributor to discomfort in the home. Poor air quality can be anything from excess humidity in the air to bacteria and mold spores or even gasses emitting from your furnace or air conditioner. We have a variety of methods to check your home's air quality and report back to you. Some problems may be a minor nuisance and others could be life threatening.
4. Home Ventilation and Pressure Even when you're not home, there are a variety of physical activities taking place that you can't see. Your home is a living and breathing entity with constant air movement - even when the heating or cooling system is turned off. The degree to which your home is sealed up or unsealed affects pressures that determine the way air travels throughout the home. This pressure can be controlled through proper venting and ducting depending on what is required. Air balancing can help correct these pressure imbalances. This process should only be performed by technicians who are trained and certified, and have the right instruments to measure and adjust the air in your home.
Here are some additional things you should consider when purchasing heating or air conditioning systems. The information provided below by Service Roundtable will help you make the best investment.
Because of the investment, replacing a heating and air conditioning system necessitates more due diligence. The best company to select for a replacement is a contractor who has performed satisfactorily for you in the past. An established, successful relationship is always the best gauge of what you can expect in the future. Relationship or not, the following are four items you should insist upon.
1. Will the company offer an AHRI Certified combination? The Air-Conditioning, Heating & Refrigeration Institute certifies product efficiency. If you are replacing your air conditioner or heat pump, a reputable contractor will present you with a certification of performance from ARI. Without replacing the condensing unit (outdoor unit) and the evaporator (air handler or indoor unit), a contractor cannot promise you will receive the efficiency you pay for, or even that the system will operate correctly over time.
2. Will the contractor permit equipment replacements? If you replace your heating or cooling system, you should insist that the job is permitted. When jobs are permitted, a municipal inspector will review the installation to ensure the job can at least meet current building codes. Like licensing, building codes are the minimum standard.
3. Is the company willing to provide references? If you do not know anyone who has done work for a company, ask for references. The contractor should be willing to provide you with three to five recent customers you can call.
4. Will the company provide you with a copy of a “load calculation?” A load calculation is a method of sizing equipment. It’s often called a “Manual J®” for the Air Conditioning Contractors of America’s Manual J®, the standard for sizing residential equipment. Once measurements are taken, load calculations can be conducted quickly using computers. Contractors should be able to show and review the load calculations and provide you with a copy if you authorize the company to proceed with the replacement.
3 Things to Beware Be especially careful about the following four pitfalls.
1. Beware the lowest price You want to spend the least amount possible, which often eliminates the lowest price. Cheap contractors typically cut corners, which costs more in the long run. Cheap contractors cannot afford to fix mistakes, resulting in the need to pay twice. Often the lowest price is not the lowest at all.
2. Beware the yellow pages Selecting a contractor from the yellow pages is tantamount to throwing a dart. Maybe you will get lucky. Maybe not. The yellow pages should be used as tool of last resort.
3. Beware anything that sounds too good to be true Usually, something too good to be true really is too good to be true.
Selecting a company to install heating or air conditioning in your home can sometimes be difficult because there are so many to choose from. Below is a list provided by Service Roundtable of things you can look for to help make your decision.
Heating & Air Conditioning Contractor Selection Checklist
12 Things to Look For, Before Calling
With just a little observation, you can determine much about a company. You can find the following by direct observation, talking with friends and neighbors, and a quick review of the company’s website or advertising. If you do not know an answer, ask when you call.
1.Is the contractor referred by a friend or neighbor?
The best source of information about the quality of work, friendliness, and customer service is the experiences of friends or neighbors.
2. Does the company fleet reassure you?
Contractors driving unmarked, beat up, dirty vehicles and likely to treat your home similarly.In addition, these contractors may be skating on the edge of bankruptcy and unwilling or unable to fulfill their warranty requirements.
3.Does the company have a physical address?
While many contractors may operate out of a home office when starting, they do have a physical address.Fly-by-nights and moonlighters, who will not remain around to stand behind their work, do not.They operate companies from cell phones.
4. Are company employees neat, clean, and professional?
Companies that provide employees with uniforms and insist on moderate levels of grooming tend to take a more professional approach across the board.Fly-by-nights are more likely to wear dirty jeans and tee shirts.
5. Does the company employ NATE certified technicians?
Similar to the ASE program for the automotive industry, NATE is the heating and air conditioning industry’s technician certification program.
6.Does the company have a website?
Similar to a physical address, a website is a sign of legitimacy. Most heating and air conditioning companies have a web presence today.
7.Will the company guarantee a price before work begins?
Most contractors utilize a national flat rate pricing service today.The service uses national standard times for repairs, allowing the contractor to offer a fixed price quote before work begins, rather than an open-ended parts and labor estimate.
8.What warranties are offered?
Better contractors, who are more confident in their work, offer better warranties.
9.Is the contractor licensed?
Licensing is a minimum requirement.Under no circumstances should you allow an unlicensed contractor to work on your equipment.
10.Is the contractor fully insured?
If an employee of an uninsured contractor is hurt on your property, you can be held liable for medical expenses.Reputable contractors will provide copies of their general liability and workers compensation insurance.If the contractor uses subcontractors (e.g., an electrician or an insulation company), ask for copies of their insurance.
11.Is the company part of your community?
A company that’s involved in your community has a greater stake in their local reputation than one not involved.Problems will arise from time to time and companies with a stake in the community tend to put forth an extra effort to resolve problems.
12.Is the company part of a professional community?
Companies that belong to a trade association or business alliance are companies committed to their craft.They care more.Quality is better.The level of professionalism is higher.
During an asthma attack, the airways get narrow, making it difficult to breathe.
Symptoms of asthma include wheezing, shortness of breath, and coughing.
Asthma can even cause death.
If you have asthma or a child with asthma, you are not alone.
About 17 million Americans have asthma.
Asthma is the leading cause of long-term illness in children.
The air that children breathe can make a difference.
Asthma may be triggered by allergens and irritants that are common in homes.
Help your child breathe easier: consult a doctor and reduce asthma triggers in your home.
Clear Your Home of Asthma Triggers
Below are five common asthma triggers found in homes and what you can do to reduce you and your child's exposure to them. Not all of the asthma triggers listed here affect every person with asthma. Not all asthma triggers are listed here. See your doctor or health care provider for more information.
Secondhand Smoke
Asthma can be triggered by the smoke from the burning end of a cigarette, pipe, or cigar and the smoke breathed out by a smoker.
Choose not to smoke in your home or car and do not allow others to do so either.
Dust Mites
Dust mites are too small to be seen but are found in every home.
Dust mites live in mattresses, pillows, carpets, fabric-covered furniture, bedcovers, clothes, and stuffed toys.
Wash sheets and blankets once a week in hot water.
Choose washable stuffed toys, wash them often in hot water, and dry thoroughly. Keep stuffed toys off beds.
Cover mattresses and pillows in dust-proof (allergen-impermeable) zippered covers.
Pets
Your pet’s skin flakes, urine, and saliva can be asthma triggers.
Consider keeping pets outdoors or even finding a new home for your pets, if necessary.
Keep pets out of the bedroom and other sleeping areas at all times, and keep the door closed.
Keep pets away from fabric-covered furniture, carpets, and stuffed toys.
Molds
Molds grow on damp materials. The key to mold control is moisture control.
If mold is a problem in your home, clean up the mold and get rid of excess water or moisture.
Lowering the moisture also helps reduce other triggers, such as dust mites and cockroaches.
Wash mold off hard surfaces and dry completely. Absorbent materials, such as ceiling tiles and carpet, with mold may need to be replaced.
Fix leaky plumbing or other sources of water.
Keep drip pans in your air conditioner, refrigerator, and dehumidifier clean and dry.
Use exhaust fans or open windows in kitchens and bathrooms when showering, cooking, or using the dishwasher.
Vent clothes dryers to the outside.
Maintain low indoor humidity, ideally between 30-50% relative humidity. Humidity levels can be measured by hygrometers which are available at local hardware stores.
Pests
Droppings or body parts of pests such as cockroaches or rodents can be asthma triggers.
Do not leave food or garbage out.
Store food in airtight containers.
Clean all food crumbs or spilled liquids right away.
Try using poison baits, boric acid (for cockroaches), or traps first before using pesticidal sprays.
If sprays are used:
Limit the spray to infested area.
Carefully follow instructions on the label.
Make sure there is plenty of fresh air when you spray, and keep the person with asthma out of the room.
Also...
House dust may contain asthma triggers. Remove dust often with a damp cloth, and vacuum carpet and fabric-covered furniture to reduce dust build-up. Allergic people should leave the area being vacuumed. Using vacuums with high efficiency filters or central vacuums may be helpful.
When your local weather forecast announces an ozone action day, stay indoors as much as possible.

National Academy of Sciences Report - "Clearing the Air: Asthma and Indoor Air Exposures"
Two years ago, the Environmental Protection Agency (EPA) asked the National Academy of Sciences (NAS) to undertake an assessment of the role of indoor air quality in the growing asthma problem. EPA asked NAS to characterize the state of the science on health impacts and prevention strategies, and to provide recommendations on needed research. In response to this request, the National Academy of Sciences Institute of Medicine has issued a report, Clearing the Air: Asthma and Indoor Air Exposures, on the role of indoor environmental pollutants in the development and exacerbation of asthma. The report affirms the Administrator's asthma initiative to educate the public about the ways they can help control asthma by managing indoor air quality. The report concludes that exposure to indoor pollutants is an important contributor to the asthma problem in this nation. Asthma sufferers should consult with their doctor about reducing their exposure to secondhand smoke, dust mites, pet dander, molds, and cockroaches. The executive summary of the NAS report is available at
A typical gas oven will produce high amounts of carbon monoxide (CO). This is normal and allowable by design. But what homeowners miss is you need to run a vented rangehood while cooking. When I say vented hood I mean one that actually vents outside. Not the style that just suck the air up and blow it back into the home.
A gas oven will commonly produce 200-300 PPM of CO. According to Iowa State University they are allowed to produce upto 800 PPM. When testing gas ovens in homes I have found this to be true. Homeowners commonly do not understand this and will cook with out turning on the rangehood vent. There are many homes that don't even have a vented rangehood.
This is one of the many reasons you can not use an oven to heat your home. Long use of the oven can over come the home with high levels of CO which can be very dangerous.
It is very important that any home with a gas range has a low level Carbon Monoxide Monitor. Not just a carbon monoxide alarm. Some states like Minnesota require CO alarms in homes, but not CO Monitors. A CO Monitor will alarm you with levels as low as 5 PPM in your home. A Carbon Monoxide alarm from your hardware store will not notify you until levels as high as 75 PPM in the home.

Tap Water Scalds: Safety Alert
The temperature a water heater should be has multiple answers. Below is a document from the "U.S. Consumer Product Safety Commission". 120 degrees has been a common answer. Homeowners that have electric off peak water heaters commonly need to keep water warmer. There has also been studies that say you need water to be 140-145 degrees to prevent bacteria growth. When you do set your water heater higher than 120 degrees you need to add a mixing valve. A mixing valve will allow you to have the tank temperature 140 degrees, but it will mix cold water with the outlet water lowering it to 120 degrees or what ever you set it at. Mixing valves are also called Anti-scald valves.
Document #5098
Each year, approximately 3,800 injuries and 34 deaths occur in the home due to scalding from excessively hot tap water. The majority of these accidents involve the elderly and children under the age of five. The U.S. Consumer Product Safety Commission (CPSC) urges all users to lower their water heaters to 120 degrees Fahrenheit. In addition to preventing accidents, this decrease in temperature will conserve energy and save money.
Most adults will suffer third-degree burns if exposed to 150 degree water for two seconds. Burns will also occur with a six-second exposure to 140 degree water or with a thirty second exposure to 130 degree water. Even if the temperature is 120 degrees, a five minute exposure could result in third-degree burns.
Various procedures for lowering water temperature in the home exist, depending on the method of heating. Here are some suggestions:
Electric water heaters. Call your local electric company to adjust the thermostat. Some companies offer this service at no-charge. Hot water should not be used for at least two hours prior to setting. To make the adjustment yourself, start by shutting off current to the water heater, then turn off the circuit breaker to the heater or remove the fuse that serves the heater. Most electric water heaters have two thermostats, both of which must be set to a common temperature for proper operation. To reach these thermostats you must remove the upper and lower access panels. Adjust the thermostat following the instructions provided with the appliance. Hold a candy or meat thermometer under the faucet to check water temperature.
Gas water heaters. Because thermostats differ, call your local gas company for instructions. Where precise temperatures are not given, hold a candy or meat thermometer under faucet for most accurate reading first thing in the morning or at least two hours after water use. If reading is too high, adjust thermostat on heater, according to manufacturers instructions, and check again with thermometer.
Furnace heater. If you do not have an electric, gas, or oil-fired water heater, you probably have an on-line hot water system. Contact your fuel supplier to have the temperature lowered. If you live in an apartment, contact the building manager to discuss possible options for lowering your tap water temperature. Reducing water temperature will not affect the heating capacity of the furnace.
The CPSC notes that a thermostat setting of 120 degrees Fahrenheit (49 degrees Celsius) may be necessary for residential water heaters to reduce or eliminate the risk of most tap water scald injuries. Consumers should consider lowering the thermostat to the lowest settings that will satisfy hot water needs for all clothing and dish washing machines. Never take hot water temperature for granted. Always hand-test before using, especially when bathing children and infants. Leaving a child unsupervised in the bathroom, even if only for a second, could cause serious injuries. Your presence at all times is the best defense against accidents and scaldings to infants and young children.
