Tips for Cleaning Your AC System

September 20, 2019

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

If you haven’t washed it recently, it could be clogged with dirt and yard waste. This collection can reduce your unit’s efficiency and cause it to malfunction. Or make it wear out faster.

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

Routine AC maintenance also helps our technicians locate and address minor issues before they develop into expensive problems.

Some of the work we complete involves:

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

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

There’s also some maintenance you can do by yourself between professional tune-ups. It only takes about an hour to wash your outdoor condenser unit, as well as a couple of pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

Select a warm day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is great. That way, you can check your system 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 juice to your air conditioner at the breaker box.

2. Clean the Outside

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

Then run the vacuum to gently clean the metallic fins. These pieces are also called as condenser coils and divert heat away from your unit.

You need to be considerate of these delicate coils. Bent or crinkled fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to straighten bent fins. You can also use a fin comb from an appliance parts store. A pro from Central Aire Heating & A/C Inc should take care of severe damage.

4. Clean the Inside

After taking out the fan, fish out leaves and other yard litter. Then mop the inside of the equipment with a wet rag.

The only coil cleaner you have to have is water. Use slight pressure from a hose nozzle to clean the fins, showering 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 properly, reach out to us a call at 318-855-2326.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Turn off the juice to your furnace at the breaker box.

2. Check Your Filter

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

Not sure when you last put in a new one? Take it out and tilt it toward the light. If light isn’t visible, get 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 dirty, you can freshen it by draining water-down bleach through the tube to flush the line. Or you can buy a new tube.

Scrub the drain port using a small, round paintbrush. Hook up the drain tube and turn the power back on.
