Expert Answers for Your Top Cooling FAQs

An air conditioner typically lasts 10 to 15 years or more, but also depends on a variety of factors. Proper installation, exposure to the elements, and keeping up with routine A/C maintenance will improve the longevity and performance of your unit. If your unit is 15 years old or older, needs frequent repairs, or can no longer keep up with your cooling demands, it’s time to start budgeting for a newer air conditioner. The good news is today’s models offer substantially more efficiency and programmable options than the previous generation.

The answer depends on your comfort and budget. When on the “auto” setting, the fan will run only to maintain your desired temperature. For example, if you set the thermostat to 72 degrees, the fan will only kick on when the temp gets warmer than that. If set in the “on” position, the A/C fan will simply run continuously, providing more even cooling throughout the house. It provides more comfort but will cost more in terms of energy usage.

You should get air conditioner maintenance once a year—ideally in spring—and for several reasons. This service is preventative, meaning a certified technician will use a thorough checklist to address small, existing issues before they become larger, more expensive repairs. He will also clean your system from top to bottom. An annual A/C tune-up will also keep your unit under warranty if you have one. Even if your system seems to be running just fine, do not skip this important and affordable service.

• Architecture of home
• Number of people in household
• Amount of windows
• Quality of ductwork
• Local climate
• Sun or shade exposure
