Tips for Cleaning Your AC System in Manassas

With summer coming to an end in Manassas, now is a good time to get ahead on air conditioner maintenance.

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

We suggest having your air conditioning system professionally maintained annually. Why? Clean equipment can be more energy efficient, which could save you money on energy costs.

Routine AC maintenance also helps our technicians spot and handle slight issues before they turn into costly problems.

There’s also some upkeep you can do on your own between professional tune-ups. You just need about an hour to wash 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 clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can run your equipment 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

Cut the electricity to your air conditioner at the breaker box.

2. Clean the Outside

Take out rubbish from the equipment. 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 transfer heat away from your unit.

You need to be considerate of these fragile coils. Misshapen or crinkled fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange bent fins. You can also buy a fin comb from an appliance parts store. A pro from Air-Right Energy Design, Inc. should fix extensive damage.

4. Clean the Inside

After extracting the fan, fish out leaves and other yard litter. Then clean the inside of the unit with a wet rag.

The only coil cleaner you have to have is water. Use light pressure from a hose nozzle to rinse the fins, spraying water from the inside out. Reinstall the fan 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 properly, contact us a call at 703-260-1148.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the power to your furnace at the breaker box.

2. Check Your Filter

Furnace filters must be replaced every several months, depending on the kind you use.

Not sure when you last checked yours? Pull it out and angle 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 examine your air conditioner’s drain line—it’s a pliable plastic tube. If it’s scummy, you can freshen it by pouring thinned bleach through the tube to flush the line. Or you can buy a new tube.

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