Tips for Cleaning Your AC System

With summer winding down in Buellton, now is an ideal time to get ahead on air conditioner maintenance.

If you haven’t washed it this year, it could be clogged with mud and yard refuse. This collection can reduce your unit’s efficiency and cause it to stop working. Or require replacement sooner.

We suggest having your air conditioning system professionally maintained once a year. Why? Clean equipment can be more energy efficient, which could save you money on utility bills.

Consistent AC maintenance also helps our technicians discover and take care of small issues before they turn into costly problems.

Some of the work we do includes:

  • Viewing the blower, motor, drain line and coils
  • Checking pressure and temperature
  • Reviewing lines, refrigerant levels and connections

It’s not too late to have maintenance done this fall—and we can get your furnace prepared for heating season too.

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 components on your indoor HVAC system.

How to Clean Your Outside AC Unit

Pick a warm day to clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can test the unit once you’ve cleaned it.

You’ll only need a few things:

  • 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

Remove waste from the system. This includes branches, bushes, weeds and grass.

Then turn on the vacuum to cautiously clean the metallic fins. These pieces are also called as condenser coils and transfer heat away from your equipment.

You need to be considerate of these delicate coils. Bent or crushed fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to straighten misshapen fins. You can also use a fin comb from an appliance parts website. A pro from Allstar Heating & Air Conditioning should take care of extensive damage.

4. Clean the Inside

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

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

5. Test Your Air Conditioner

It’s safe to restore power and turn your air conditioner back on. If it’s not operating properly, give us a call at 805-242-9638.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut the power to your furnace at the breaker box.

2. Check Your Filter

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

Unsure when you last replaced yours? Take it out and angle it toward the light. If light isn’t visible, buy 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 scummy, you can freshen it by pouring thinned bleach through the tube to sanitize the line. Or you can get a new tube.

Wash the drain port using a small, round paintbrush. Hook up the drain tube and restore power.
