How Do I Choose the Right Air Conditioning System?

Start With Proper Sizing

The most important step is matching cooling capacity to your home. An undersized unit will run constantly and struggle to keep up on hot days, while an oversized unit short cycles, cools unevenly, and removes less humidity. Cooling capacity is measured in tons, and the right size depends on square footage, insulation, windows, climate, and your ductwork. A proper load calculation, not a guess based on the old unit, gives you the correct size.

Understand Efficiency Ratings

Air conditioner efficiency is measured by SEER2, the ratio of cooling output to energy used over a season. A higher SEER2 unit uses less electricity for the same cooling, which can lower your summer bills. Higher efficiency models often cost more up front, so weigh the long term savings against your climate and how long you plan to stay in the home. The highest rating is not automatically the best fit for every household.

Match the Components

A central system is a set of parts that must be rated to work together for the efficiency and warranty to hold.

Check the Specs Before You Buy

Once you know your size and target efficiency, review the published specs for each unit so you can compare capacity, SEER2, refrigerant type, and dimensions side by side.
