Tips for Cleaning Your AC System in Irvine

With summer coming to an end in Irvine, now is a good time to get a kick start on air conditioner maintenance.

If you haven’t taken care of it lately, it could be full of mud and debris from your yard. This buildup can decrease your unit’s efficiency and cause it to stop working. Or wear it down faster.

We suggest having your air conditioning system professionally tuned-up every year. Why? A clean unit can be more energy efficient, which could save you money on utility bills.

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

Some of the work we do consists of:

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

There’s still time to have a tune-up 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 get the grime off your outdoor condenser unit, as well as a few components on your indoor HVAC system.

How to Clean Your Outside AC Unit

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

You’ll only need a few 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 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 turn on the vacuum to gently clean the metallic fins. These parts are also called as condenser coils and move heat away from your unit.

You need to be careful with these fragile coils. Bent or crushed fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange warped fins. You can also buy a fin comb from an appliance parts website. A pro from True Home Heating and Air Conditioning should fix severe damage.

4. Clean the Inside

After extracting the fan, fish out leaves and other yard rubbish. Then clean the inside of the equipment 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 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 properly, contact us a call at 949-258-7259.

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 must be exchanged every couple of months, depending on the model you use.

Can’t remember when you last replaced yours? Take it out and hold it up to the light. If there’s no light visible, get a new one.

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 freshen it by flowing thinned bleach through the tube to clean 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.
