Tips for Cleaning Your AC System in Mount Pleasant

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 washed it this year, it could be blocked with dust and yard refuse. This collection can limit your unit’s efficiency and cause it to malfunction. Or require replacement faster.

We recommend having your air conditioning system professionally serviced annually. Why? A clean system can be more energy efficient, which could save you money on energy expenses.

Regular AC maintenance also helps our technicians spot and address slight issues before they become expensive problems.

Some of the work we do includes:

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

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

There’s also some maintenance you can do by yourself between professional tune-ups. You just need about an hour to clean your outdoor condenser unit, as well as a couple of components on your indoor HVAC system.

How to Clean Your Outside AC Unit

Select a mild 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

Remove rubbish from the equipment. This includes branches, bushes, weeds and grass.

Then run the vacuum to slowly clean the metallic fins. These pieces are also called as condenser coils and divert heat away from your equipment.

You need to be careful with these delicate coils. Misshapen or crinkled 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 take care of extensive damage.

4. Clean the Inside

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

The only coil cleaner you need is water. Use light pressure from a hose nozzle to clean the fins, directing 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 like it should, reach out to us a call at 843-485-0967.

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

Unsure when you last replaced yours? Remove it and hold it up to the light. If there’s no light 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 supple plastic tube. If it’s scummy, you can sanitize it by pouring thinned bleach through the tube to sanitize 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.
