Tips for Cleaning Your AC System

September 20, 2019

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

If you haven’t washed it lately, it could be blocked with dust and debris from your yard. This buildup can limit your unit’s efficiency and cause it to malfunction. Or require replacement sooner.

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

Regular AC maintenance also helps our technicians discover and handle minor issues before they develop into expensive problems.

Some of the work we do involves:

  • Inspecting the blower, motor, drain line and coils
  • Checking pressure and temperature
  • Reviewing lines, refrigerant levels and connections

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

Schedule maintenance now


There’s also some maintenance 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 several pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

Pick a temperate day to clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can check your equipment once you’ve cleaned it.

You’ll only need a handful of 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

Empty rubbish from the unit. This includes branches, bushes, weeds and grass.

Then run the vacuum to slowly clean the metallic fins. These pieces are also referred to as condenser coils and transfer heat away from your system.

You need to be cautious with these fine coils. Warped or crumpled fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange warped fins. You can also use a fin comb from an appliance parts store. A pro from Booneville Heating & Cooling LLC should fix severe damage.

4. Clean the Inside

After extracting the fan, pull out leaves and other yard rubbish. Then clean the inside of the system 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, directing water from the inside out. Replace the fan once you’re completed.

5. Test Your Air Conditioner

You can now restore power and turn your air conditioner back on. If it’s not operating like it should, give us a call at 662-269-8716.

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 several months, depending on the model 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 flexible plastic tube. If it’s dirty, you can clean it by flowing thinned bleach through the tube to flush the line. Or you can get a new tube.

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