Tips for Cleaning Your AC System

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

If you haven’t washed it this year, it could be full of dirt and yard refuse. This collection can decrease your unit’s efficiency and cause it to stop working. Or require replacement more quickly.

We recommend 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 energy expenses.

Regular AC maintenance also helps our technicians locate and take care of small issues before they turn into high-priced problems.

Some of the work we perform consists of:

  • Taking a look at the blower, motor, drain line and coils
  • Watching pressure and temperature
  • Reviewing lines, refrigerant amounts and connections

You can still have service done this fall—and we can get your furnace prepped for heating season too.

There’s also some work 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 a few components on your indoor HVAC system.

How to Clean Your Outside AC Unit

Select a temperate day to wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can run your equipment 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 power 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 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 cautious with these delicate coils. Misshapen or crushed fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange misshapen fins. You can also use a fin comb from an appliance parts store. A pro from Cool Air Solutions should take care of extensive damage.

4. Clean the Inside

After removing the fan, dig out leaves and other yard rubbish. Then clean the inside of the equipment with a wet rag.

The only coil cleaner you should use is water. Use gentle pressure from a hose nozzle to clean the fins, showering water from the inside out. Reinstall 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 properly, reach out to us a call at 951-299-9853.

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 need to be changed every few months, depending on the model you use.

Can’t remember when you last put in a new one? Take 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 flexible plastic tube. If it’s dirty, you can freshen it by flowing diluted bleach through the tube to sanitize the line. Or you can buy a new tube.

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