If you're confronted with the prospect of buying a new heating and air system, you may be surprised to find that you know almost nothing about where to start. This is a common predicament for homeowners who may never have thought much about their HVAC system beyond the vents and the filters. Of course, purchasing a new unit does not need to be a complicated endeavor, though it requires a bit of thought to make sure you meet your needs without vastly excluding them. Here is some information that will help you make the choice.
Types
One of the first things you'll notice is that there are probably more types of heating and air systems on the market than you would have expected. Some are electric, some run on gas, while still others function by using a hybrid of the two. Even within various units that use the same power source, there are big differences between them. The power source you choose to use will probably be based on what you've used for most of your life, meaning electricity for most people in urban areas.
Features
As with any product designed to be sold to a mass market, manufacturers have attempted to attract business by supplying their heating and air units with as many special features as they can. Some of these features are beneficial and superfluous, while others can make a significant difference in both the price of the unit and its ease of use. One such feature would be ductless air conditioning, which has gotten a lot of praise in certain circles. On the flip side, a feature like a glow in the dark thermostat may be helpful, but it probably will not be a big factor when it comes down to it.
Size
Probably the most important consideration when purchasing a heating and air system is the size and how it relates to your home. Buy a unit that is too small, and it will work night and day to bring your home to the temperature you desire. Buy a unit that is too large, and it will be constantly flipping off and on, putting additional wear and tear on the system. It will also cost much more up front, which is an unnecessary waste if you do not have the space to justify it. Most homeowners find it fruitful to work closely with an installation representative who can come out to your home and make a professional recommendation as it pertains to buying the right size.
