Air Conditioning Maintenance and Tune-Ups

With proper maintenance, your cooling system can last an average of 15 years. Maintenance is important to improve the efficiency of your unit and increase the lifetime of the unit. Plus, an efficient system can save energy and money

A thorough air conditioning tune-up will help make sure your unit is operating at peak efficiency. Even little things like a partially clogged indoor or outdoor coil, an improper refrigerant level or a dirty air filter will cause your air conditioner to work harder and use more energy than it needs to.

What to expect during your 21-point AC Tune-Up

Your air conditioning inspection or tune-up will take about 35 minute to an hour and will focus on your outdoor unit. Your technician will complete a 21-point checklist that includes inspecting the overall operating status of the unit, refrigerant charge, drain line and more. Check out our blog to read more about what to expect during your air conditioning tune-up.
