Tips for Cleaning Your AC System

September 20, 2019

With summer winding down in Anaheim, now is a great time to get ahead on air conditioner maintenance.

If you haven’t cleaned it recently, it could be blocked with dust and yard refuse. This accumulation can limit your unit’s efficiency and cause it to malfunction. Or wear it down sooner.

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

Consistent AC maintenance also helps our technicians locate and take care of slight issues before they turn into expensive problems.

Some of the work we do consists of:

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

You can still have a tune-up done this fall—and we can get your furnace prepped for heating season too.

There’s also some upkeep you can do on your own between professional tune-ups. You only need about an hour to clean your outdoor condenser unit, as well as a few parts on your indoor HVAC system.

How to Clean Your Outside AC Unit

Select a mild day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can check your system 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

Switch off the juice to your air conditioner at the breaker box.

2. Clean the Outside

Take out waste from the equipment. 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 equipment.

You need to be cautious with these delicate coils. Bent or crumpled 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 Eco Fresh HVAC Inc. should take care of large amounts of damage.

4. Clean the Inside

After removing the fan, dig out leaves and other yard waste. Then wipe the inside of the unit with a wet sponge.

The only coil cleaner you need is water. Use slight pressure from a hose nozzle to wash the fins, directing water from the inside out. Replace the fan once you’re completed.

5. Test Your Air Conditioner

It’s safe to restore power and turn your air conditioner back on. If it’s not working like it should, reach out to us a call at 714-855-1717.

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 replaced every few months, depending on the kind you use.

Can’t remember when you last checked yours? Take it out and hold it up to the light. If light isn’t visible, replace it.

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 moldy, you can clean it by pouring water-down bleach through the tube to flush the line. Or you can get a new tube.

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