This summer, staying cool goes beyond just wearing sunglasses and shorts. Being comfortable in the home means having the right air conditioning system that is best suited for your particular property.

Here are some important factors that are used to consider how an air conditioning system is chosen for a home:

Understanding AC Measurements
Air-conditioning systems are rated by the seasonal energy-efficiency rating (SEER) and measured by tonnage. The SEER rating indicates how energy efficient the unit is—the higher the SEER rating, the more efficient the unit. Tonnage, meanwhile, indicates the operational size of the unit. A single AC ton is equivalent to 12,000 Btu per hour (Btu/h), or approximately the amount of coolness emitted by 1 ton of ice melting over the course of one day. An average 2,500-square-foot home might require a 3.5- to 4.5-ton unit, but there are many variables, and getting the tonnage exactly right is vital to both controlling cooling costs and maintaining comfort.

Size Matters
An undersized AC unit is unlikely to cool a house adequately. It simply doesn’t have the power to do the job. But bigger isn’t always better. When an AC unit is too large, it will cool your house quickly, but then it will shut itself down because it’s reached the desired temperature. While that might not sound so bad on the surface, you’ll soon realize that your home never quite reaches the comfort level you expect. If an oversized unit cools the air and then shuts off too soon, it never has the opportunity to dry the air effectively, leaving much of the humidity (and general stickiness) unresolved.’ (Glenda Taylor,
