Evaluating the best air conditioning systems for your home or office depends on two things: the level of air conditioning that you need in relation the square footage of your structure and the characteristics that you desire in an air conditioner. Because installing a central air conditioning system is expensive, some people try to cut corners and install a lower tonnage air conditioner than their space requires, which results in an over worked air conditioner and an insufficient level of cooling. But there are also cases where people install a larger air conditioner than they need under the impression that it will provide better cooling, which it won’t. Instead, the unit will cycle on and off too often, causing it to wear prematurely and resulting in significantly higher electric bills.

The best way to determine the right size air conditioner for your property is to have an air conditioning repair and installation service analyze your air conditioning needs, which, in addition to square footage, will depend on such factors as the thermal efficiency of doors and windows, the presence of direct shade, your structure’s landscape orientation and the placement of windows.

Once you know what level of air conditioning capacity you need, it’s time to decide what kind air conditioner you want. Aside of brand preference, most people’s consideration of which air conditioner to buy comes down to an air conditioner’s SEER rating (the level of energy efficiency that it offers). While an energy efficient air conditioner is more environmentally friendly, it will also reduce your electric bills in hot weather, potentially saving you multiple thousands of dollars a year if you live in a hot climate. In many cases, energy efficient air conditioners cost more than traditional air conditioners. But the lower electric bills that they bring can more than make up for the difference in cost within a short period of time.
