Tips for Cleaning Your AC System

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

If you haven’t washed it lately, it could be clogged with dust and yard waste. This buildup can limit your unit’s efficiency and cause it to break down. Or wear it down sooner.

We recommend having your air conditioning system professionally maintained once a year. Why? A clean system can be more energy efficient, which could save you money on electric costs.

Consistent AC maintenance also helps our technicians spot and take care of slight issues before they become high-priced problems.

Some of the work we do includes:

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

You can still 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 by yourself between professional tune-ups. You only need about an hour to clean your outdoor condenser unit, as well as several parts 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 check your equipment once you’ve cleaned it.

You’ll only need a couple 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

Stop the electricity to your air conditioner at the breaker box.

2. Clean the Outside

Take out rubbish from the system. This includes branches, bushes, weeds and grass.

Then run the vacuum to gently clean the metallic fins. These parts are also referred to as condenser coils and move heat away from your equipment.

You need to be considerate of these fragile coils. Misshapen or crumpled fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange bent fins. You can also get a fin comb from an appliance parts store. A pro from Giordanos Heating and Air Conditioning should take care of severe damage.

4. Clean the Inside

After taking out the fan, dig out leaves and other yard rubbish. Then wipe the inside of the system with a wet sponge.

The only coil cleaner you should use is water. Use light pressure from a hose nozzle to wash the fins, directing water from the inside out. Put the fan back in once you’re finished.

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, contact us a call at 203-734-7648.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Turn off the power to your furnace at the breaker box.

2. Check Your Filter

Furnace filters need to be changed every several months, depending on the kind you use.

Unsure when you last checked yours? Take it out and tilt 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 take a look at your air conditioner’s drain line—it’s a flexible plastic tube. If it’s scummy, you can freshen it by draining 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. Reconnect the drain tube and restore power.
