Tips for Cleaning Your AC System

September 20, 2019

With summer ending in East Bernard, now is a great time to get a head start on air conditioner maintenance.

If you haven’t washed it this year, it could be full of mud and debris from your yard. This accumulation can reduce your unit’s efficiency and cause it to malfunction. Or wear it down sooner.

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 energy bills.

Consistent AC maintenance also helps our technicians spot and take care of minor issues before they develop into expensive problems.

Some of the work we perform includes:

  • Inspecting the blower, motor, drain line and coils
  • Watching 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 ready for heating season too.

There’s also some maintenance you can do alone between professional tune-ups. It only takes about an hour to clean 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 mild day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can test the unit 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 debris from the unit. This includes branches, bushes, weeds and grass.

Then use the vacuum to slowly clean the metallic fins. These components are also known as condenser coils and move heat away from your system.

You need to be careful with these fragile coils. Bent or crinkled fins can impact 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 E.B. Air, LLC should take care of large amounts of damage.

4. Clean the Inside

After removing the fan, fish out leaves and other yard waste. Then wipe the inside of the system with a wet rag.

The only coil cleaner you need is water. Use slight pressure from a hose nozzle to rinse the fins, showering water from the inside out. Reinstall 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 correctly, give us a call at 979-335-4262.

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 must be changed every few months, depending on the kind you use.

Can’t remember when you last put in a new one? Take it out and angle 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 examine your air conditioner’s drain line—it’s a supple plastic tube. If it’s scummy, you can clean it by flowing 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 switch the power back on.
