Tips for Cleaning Your AC System

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

If you haven’t taken care of it this year, it could be full of mud and yard waste. This collection can limit your unit’s efficiency and cause it to stop working. Or make it wear out more quickly.

We recommend having your air conditioning system professionally serviced annually. Why? Clean equipment can be more energy efficient, which could save you money on electric costs.

Routine AC maintenance also helps our technicians spot and take care of small issues before they become expensive problems.

Some of the work we do includes:

  • Taking a look at the blower, motor, drain line and coils
  • Confirming pressure and temperature
  • Testing lines, refrigerant totals and connections

There’s still time to have maintenance done this fall—and we can get your furnace prepared for heating season too.

There’s also some maintenance you can do on your own between professional tune-ups. You only need about an hour to clean your outdoor condenser unit, as well as a couple of pieces 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 great. That way, you can check your equipment once you’ve cleaned it.

You’ll only need a handful 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

Switch off the electricity to your air conditioner at the breaker box.

2. Clean the Outside

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

Then run the vacuum to slowly clean the metallic fins. These components are also called as condenser coils and transfer heat away from your unit.

You need to be cautious with these delicate coils. Misshapen or crumpled fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to straighten warped fins. You can also use a fin comb from an appliance parts retailer. A pro from Olde Towne Heating & Air should fix extensive damage.

4. Clean the Inside

After extracting the fan, dig out leaves and other yard rubbish. Then wipe the inside of the equipment with a wet cloth.

The only coil cleaner you need is water. Use light pressure from a hose nozzle to clean the fins, spraying water from the inside out. Replace the fan once you’re finished.

5. Test Your Air Conditioner

You can now restore power and turn your air conditioner back on. If it’s not operating correctly, reach out to us a call at 843-485-0967.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the power 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.

Can’t remember when you last replaced yours? Remove it 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 inspect 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 clean the line. Or you can replace the tube.

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