Tips for Cleaning Your AC System

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

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

We advise having your air conditioning system professionally serviced once a year. Why? A clean unit can be more energy efficient, which could save you money on energy expenses.

Regular AC maintenance also helps our technicians spot and take care of small issues before they turn into costly problems.

Some of the work we do includes:

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

It’s not too late to have service done this fall—and we can get your furnace prepped for heating season too.

There’s also some work you can do on your own between professional tune-ups. You only need about an hour to wash your outdoor condenser unit, as well as a few pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

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

You’ll only need a few tools:

  • 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 waste from the unit. This includes branches, bushes, weeds and grass.

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

You need to be cautious with these delicate coils. Misshapen or crushed fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange misshapen fins. You can also use a fin comb from an appliance parts website. A pro from ACS Heating and Air Conditioning should take care of extensive damage.

4. Clean the Inside

After removing the fan, pull out leaves and other yard rubbish. Then clean the inside of the unit with a wet cloth.

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

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not running correctly, reach out to us a call at 770-450-1539.

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 exchanged every several months, depending on the type you use.

Not sure when you last replaced yours? Take it out and tilt it toward the light. If there’s no light visible, buy a new one.

3. Clean the Inside

Remove the blower door and vacuum up dust.

Then take a look at your air conditioner’s drain line—it’s a pliable plastic tube. If it’s moldy, you can clean it by pouring water-down bleach through the tube to flush the line. Or you can replace the tube.

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