Air conditioner on the exterior of a white house

Your air conditioner plays a huge role in keeping your home comfortable during the summer months. In addition to cooling the air, your AC reduces humidity and removes impurities from the air. The average central cooling system lasts 10 to 20 years, so chances are, you’ll find yourself in need of a new one at least once during your life. The choices can be a bit overwhelming, so we’ve put together this basic AC buying guide to help you make the right decision.


  1. Choose an Air Conditioner That’s the Right Size. Air conditioners come in a wide range of sizes, and choosing the right one is one of the most important steps in ensuring efficient and effective cooling. If the AC is too large, it will cycle on and off frequently, driving up your energy bills. If it’s too small, it may struggle to cool your entire home. Your HVAC contractor will perform a load calculation to help you determine the right size unit for your home.
  2. Pay Attention to Energy Efficiency. Even less efficient modern cooling systems are more energy efficient than older units, but some are still better than others. The federal government now requires that all air conditioners have a SEER, or Seasonal Energy Efficiency Ratio, of at east 13. For maximum efficiency, look for one with a rating of 14 to 22.
  3. Work With a Professional HVAC Contractor. Buying and installing a central air conditioning system isn’t a do-it-yourself project. Find a trusted HVAC contractor, such as Carter Services, as soon as you start looking for a new system. Your contractor will help you choose a system that provides you with exactly what you and your home need, and he or she will provide expert air conditioner installation. Your technician will also make you aware of any maintenance that’s required to ensure that your warranty isn’t voided.
