Tips for Cleaning Your AC System

With summer coming to an end in Augusta, now is a great time to get ahead on air conditioner maintenance.

If you haven’t cleaned it this year, it could be full of dirt and yard waste. This accumulation can decrease your unit’s efficiency and cause it to malfunction. Or make it wear out sooner.

We recommend having your air conditioning system professionally tuned-up annually. Why? Clean equipment can be more energy efficient, which could save you money on utility bills.

Consistent AC maintenance also helps our technicians discover and take care of slight issues before they become expensive problems.

Some of the work we perform consists of:

  • Viewing the blower, motor, drain line and coils
  • Watching pressure and temperature
  • Testing lines, refrigerant totals and connections

There’s still time to have maintenance done this fall—and we can get your furnace prepped for heating season too.

There’s also some maintenance you can do on your own between professional tune-ups. It only takes about an hour to get the grime off your outdoor condenser unit, as well as a few pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

Choose a mild day to clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can run the unit once you’ve cleaned it.

You’ll only need a couple 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 electricity to your air conditioner at the breaker box.

2. Clean the Outside

Take out rubbish from the system. This includes branches, bushes, weeds and grass.

Then use the vacuum to cautiously clean the metallic fins. These parts are also known as condenser coils and move heat away from your equipment.

You need to be cautious with these fine coils. Bent or crushed fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange misshapen fins. You can also use a fin comb from an appliance parts retailer. A pro from McCune Heating & Cooling should fix large amounts of damage.

4. Clean the Inside

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

The only coil cleaner you have to have is water. Use light pressure from a hose nozzle to rinse the fins, directing water from the inside out. Reinstall the fan 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 working correctly, reach out to us a call at 316-469-7994.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the juice to your furnace at the breaker box.

2. Check Your Filter

Furnace filters should be changed every several months, depending on the kind you use.

Can’t remember when you last replaced yours? Pull it out and tilt it toward the light. If there’s no light visible, replace it.

3. Clean the Inside

Remove the blower door and vacuum up dust.

Then inspect your air conditioner’s drain line—it’s a pliable plastic tube. If it’s moldy, you can freshen it by flowing diluted bleach through the tube to clean the line. Or you can buy a new tube.

Wash the drain port using a small, round paintbrush. Connect the drain tube and switch the power back on.
