What Are the Benefits of AC Maintenance?

Lower Monthly Utility Bills

Simple procedures, like changing an air filter or cleaning a coil, allow the unit to run much more smoothly. And when your air conditioner runs smoothly, it uses less energy—resulting in lower monthly cooling bills.

Fewer Breakdowns

Over 40 percent of air conditioning breakdowns are caused because of lack of proper AC maintenance. Once dirt gets into the system, parts are more likely to rust and get ruined. By having a qualified technician check your entire AC system, you can find problems before they arise.

Warranties

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

Air Conditioner Inspection FAQs

Is there anything I can do myself to keep my air conditioner running smoothly?

Turn off your air conditioner’s fan and gently clean the fins of your blower fan to ensure that they run smoothly. Be careful when doing this, however, because the fins bend fairly easily and may be damaged by sharp objects.

Locate your air conditioner’s condenser unit (the big box outside) and make sure it is free of leaves and other objects that can reduce its efficiency. Hose them out of the way and make sure to prune any nearby bushes and shrubs so nothing blocks your air conditioning unit. Finally, check the drain when the weather gets humid to make sure that moisture is being carried away from the system.

Make sure you keep your air conditioner’s filter well-maintained. Every month, take the filter out and clean or replace it, but make sure you put a new one back in. Never run your air conditioner without a filter – doing so can seriously damage your unit.
