Tips for Cleaning Your AC System

With summer coming to an end in Reinholds, now is a great time to get a head start on air conditioner maintenance.

If you haven’t washed it this year, it could be full of dust and debris from your yard. This collection can limit your unit’s efficiency and cause it to malfunction. Or require replacement sooner.

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

Consistent AC maintenance also helps our technicians locate and handle slight issues before they develop into expensive problems.

Some of the work we complete consists of:

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

It’s not too late to have a tune-up done this fall—and we can get your furnace prepped for heating season too.

There’s also some upkeep you can do by yourself between professional tune-ups. It only takes about an hour to get the grime off your outdoor condenser unit, as well as a couple of components on your indoor HVAC system.

How to Clean Your Outside AC Unit

Choose a mild day to scrub your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can test 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

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

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

You need to be cautious with these fine coils. Misshapen or crumpled fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to straighten misshapen fins. You can also buy a fin comb from an appliance parts website. A pro from County Line Mechanical LLC should handle severe damage.

4. Clean the Inside

After taking out the fan, fish 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 gentle pressure from a hose nozzle to wash the fins, spraying water from the inside out. Reinstall the fan once you’re done.

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not operating correctly, reach out to us a call at 717-216-0846.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

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

2. Check Your Filter

Furnace filters need to be replaced every few months, depending on the type you use.

Unsure when you last checked yours? Remove it and angle it toward the light. If you can’t see light through it, get 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 supple plastic tube. If it’s moldy, you can clean it by draining thinned bleach through the tube to flush the line. Or you can replace the tube.

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