Why Invest in AC Maintenance?

Lower monthly utility bills

Simple procedures like changing an air filter or cleaning a coil allow your unit to run much more smoothly. And when your air conditioner runs smoothly, it uses less energy!

Fewer breakdowns

Over 40% of breakdowns are caused because of lack of air conditioner maintenance. Once dirt gets into the system, parts are more likely to rust and get ruined. By scheduling regular AC inspections, you can find problems before they arise.


Most companies do not accept an air conditioner repair warranty claim if the system has issues due to lack of maintenance.
