Tips for Cleaning Your AC System

With summer winding down in Shreveport, now is an ideal time to get a head start on air conditioner maintenance.

If you haven’t washed it lately, it could be full of dust and yard waste. This accumulation can decrease your unit’s efficiency and cause it to malfunction. Or require replacement faster.

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

Consistent AC maintenance also helps our technicians discover and address slight issues before they turn into expensive problems.

Some of the work we do involves:

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

You can still 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 just need about an hour to get the grime off your outdoor condenser unit, as well as a few parts on your indoor HVAC system.

How to Clean Your Outside AC Unit

Choose a temperate day to scrub 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 things:

  • 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 power to your air conditioner at the breaker box.

2. Clean the Outside

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

Then turn on the vacuum to cautiously clean the metallic fins. These parts are also referred to as condenser coils and divert heat away from your unit.

You need to be cautious with these fine coils. Warped or crinkled fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to straighten warped fins. You can also use a fin comb from an appliance parts website. A pro from Moon's Air should fix severe damage.

4. Clean the Inside

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

The only coil cleaner you should use is water. Use gentle pressure from a hose nozzle to wash 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, give us a call at 318-215-7938.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut the juice to your furnace at the breaker box.

2. Check Your Filter

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

Can’t remember when you last checked yours? Take it out and angle it toward the light. If you can’t see light through it, 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 pliable plastic tube. If it’s dirty, you can clean it by draining diluted bleach through the tube to clean the line. Or you can buy a new tube.

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