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.
