Tips for Cleaning Your AC System

September 20, 2019

With summer winding down in Grand Prairie, now is a good time to get a head start on air conditioner maintenance.

If you haven’t taken care of it recently, it could be full of mud and yard waste. This collection can limit your unit’s efficiency and cause it to stop working. Or make it wear out sooner.

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

Routine AC maintenance also helps our technicians discover and take care of small issues before they become costly problems.

Some of the work we perform consists of:

  • Taking a look at the blower, motor, drain line and coils
  • Watching pressure and temperature
  • Testing lines, refrigerant amounts and connections

There’s still time to have a tune-up done this fall—and we can get your furnace prepared for heating season too.

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

How to Clean Your Outside AC Unit

Pick a temperate day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can run your system 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

Switch off the juice to your air conditioner at the breaker box.

2. Clean the Outside

Remove waste from the equipment. This includes branches, bushes, weeds and grass.

Then turn on the vacuum to cautiously clean the metallic fins. These pieces are also known as condenser coils and divert heat away from your equipment.

You need to be careful with these fragile coils. Warped or crushed fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to adjust warped fins. You can also buy a fin comb from an appliance parts retailer. A pro from Bon Air Service Company should fix severe damage.

4. Clean the Inside

After extracting the fan, fish out leaves and other yard waste. Then wipe the inside of the unit with a wet sponge.

The only coil cleaner you have to have is water. Use slight pressure from a hose nozzle to rinse the fins, spraying water from the inside out. Put the fan back in once you’re completed.

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not operating like it should, reach out to us a call at 972-332-1028.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut the electricity to your furnace at the breaker box.

2. Check Your Filter

Furnace filters should be replaced every few months, depending on the kind you use.

Can’t remember when you last put in a new one? Take 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 take a look at your air conditioner’s drain line—it’s a flexible plastic tube. If it’s moldy, you can sanitize it by draining water-down bleach through the tube to sanitize the line. Or you can replace the tube.

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