Why Get Central Air Conditioning Tune-Ups Regularly?

air conditioner with maintenance reminder

According to the U.S. Energy Information Administration, only 42% of homeowners call a professional to perform routine maintenance or tune-ups on their AC unit. Those who do, have air conditioners lasting 40% longer than the average AC lifespan. In addition to protecting your unit down the road, you’ll see increased performance now – and savings on your energy bill.

Technical maintenance requires a professional, but we always advise our customers to replace their air filter at least every 3-6 months. This is typically a job any homeowner can take care of. The Department of Energy estimates changing your filters can reduce your home’s energy consumption by 5 to 15 percent.

How Can AC Maintenance Help You?

You will maintain good airflow. Bad filters can be tough if you have pets, allergies and other indoor air quality issues. Your central air unit will lack airflow if you do not change them regularly, which renders your system inefficient.

Savings on energy. Larger problems can arise down the road. While Certified knows you can change your air filter if you so choose, technical inspections are more difficult for the average homeowner to execute, and can make problems worse without proper experience.

Give your unit regular service, and it will work for you longer and more effectively. Did you know 87% of all homes in the U.S. have air conditioning? That’s more common than a dishwasher, garage, or dining room – combined!
