Tips for Cleaning Your AC System

September 20, 2019

With summer ending in Boynton Beach, now is an ideal time to get a head start on air conditioner maintenance.

If you haven’t cleaned it this year, it could be full of mud and yard refuse. This accumulation can reduce your unit’s efficiency and cause it to break down. Or require replacement sooner.

We advise having your air conditioning system professionally maintained every year. Why? Clean equipment can be more energy efficient, which could save you money on utility expenses.

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

Some of the work we perform includes:

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

There’s still time to have service done this fall—and we can get your furnace ready 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 wash your outdoor condenser unit, as well as several parts on your indoor HVAC system.

How to Clean Your Outside AC Unit

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

You’ll only need a handful of items:

  • 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

Empty rubbish from the unit. This includes branches, bushes, weeds and grass.

Then turn on the vacuum to gently clean the metallic fins. These pieces are also referred to as condenser coils and move heat away from your unit.

You need to be considerate of these fragile coils. Warped or crinkled fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to straighten bent fins. You can also buy a fin comb from an appliance parts retailer. A pro from A2Z Air Inc should take care of severe damage.

4. Clean the Inside

After extracting the fan, fish out leaves and other yard rubbish. Then wipe the inside of the unit with a wet sponge.

The only coil cleaner you should use is water. Use slight 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

You can now restore power and turn your air conditioner back on. If it’s not working like it should, reach out to us a call at 561-270-6228.

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 replaced every couple of months, depending on the model you use.

Not sure when you last checked yours? Pull 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 inspect your air conditioner’s drain line—it’s a flexible plastic tube. If it’s scummy, you can sanitize it by draining 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 switch the power back on.
