Tips for Cleaning Your AC System

With summer winding down in Perry, now is a great time to get a head start on air conditioner maintenance.

If you haven’t taken care of it recently, it could be clogged with dirt and debris from your yard. This collection can limit your unit’s efficiency and cause it to stop working. Or wear it down more quickly.

We recommend having your air conditioning system professionally maintained once a year. Why? A clean system can be more energy efficient, which could save you money on energy costs.

Routine AC maintenance also helps our technicians spot and take care of minor issues before they turn into expensive problems.

Some of the work we perform consists of:

  • Inspecting the blower, motor, drain line and coils
  • Confirming pressure and temperature
  • Reviewing lines, refrigerant amounts and connections

You can still have a tune-up done this fall—and we can get your furnace ready for heating season too.

There’s also some maintenance you can do by yourself between professional tune-ups. You only need about an hour to clean your outdoor condenser unit, as well as several components on your indoor HVAC system.

How to Clean Your Outside AC Unit

Pick a mild day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can check your system once you’ve cleaned it.

You’ll only need a handful of items:

  • Wet-dry vacuum and hose with a soft brush attachment
  • Screwdriver
  • Butter knife
  • Damp rag
  • Small, round paintbrush
  • Replacement furnace filter (if necessary)

5 Steps to Clean the Outside Unit

1. Turn Off the Power

Stop the juice to your air conditioner at the breaker box.

2. Clean the Outside

Remove debris from the system. This includes branches, bushes, weeds and grass.

Then turn on the vacuum to gently clean the metallic fins. These components are also known as condenser coils and transfer heat away from your unit.

You need to be considerate of these fragile coils. Warped or crumpled fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to straighten warped fins. You can also get a fin comb from an appliance parts website. A pro from Gillman Heating and Air should handle large amounts of damage.

4. Clean the Inside

After extracting the fan, dig out leaves and other yard rubbish. Then clean the inside of the equipment with a wet cloth.

The only coil cleaner you should use is water. Use light pressure from a hose nozzle to wash the fins, directing water from the inside out. Put the fan back in once you’re finished.

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not running properly, contact us a call at 478-202-3076.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the electricity to your furnace at the breaker box.

2. Check Your Filter

Furnace filters should be exchanged every several months, depending on the model you use.

Unsure when you last replaced yours? Pull it out and hold it up to the light. If light isn’t visible, replace it.

3. Clean the Inside

Remove the blower door and vacuum up dust.

Then examine your air conditioner’s drain line—it’s a flexible plastic tube. If it’s dirty, you can clean it by draining water-down bleach through the tube to clean the line. Or you can replace the tube.

Clean the drain port using a small, round paintbrush. Connect the drain tube and restore power.
