How to select a home air conditioning and heating system
Selecting which brand of comfort system is less than half the battle.
Selecting which brand of comfort system is usually on the top of the list when people make this very important decision. Unfortunately that is probably the least important part of the equation to ensure that your system will provide you and your family years of trouble free and efficient comfort.
Qualify your needs.
All of today’s equipment manufacturers rate there equipment by the ton, there are 12,000 btu’s per 1 ton of cooling. As an example, a 3 ton system would have a nominal size of 36,000 btu’s. The most important aspect of your comfort system is ensuring it is sized properly. A system that is oversized will satisfy cooling requirements much too quickly with out removing adequate humidity. Your home will feel cool but clammy, you may have problems such as bread molding quickly, clothing becoming musty and most important are the problems that moisture can cause with your homes structure. There is only one way to determine the proper size system your home will need. A heat gain calculation based on ACCA’s Manual J. Old rules of thumb such as one Ton per X number of square feet is just not accurate.
Qualify the equipment that you are considering.
Most Brands are very similar in construction. In fact a lot of brands use the same components such as fan motors, compressors, and electronics. Your choice here should be focused on efficiency, features, and there benefit compared to there cost.
Qualify the warranty for each comfort system.
