Tips for Cleaning Your AC System in Greensburg

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

If you haven’t cleaned it lately, it could be full of dirt and yard refuse. This accumulation can reduce your unit’s efficiency and cause it to stop working. Or wear it down faster.

We suggest having your air conditioning system professionally maintained once a year. Why? Clean equipment can be more energy efficient, which could save you money on electric bills.

Routine AC maintenance also helps our technicians discover and address minor issues before they develop into high-priced problems.

Some of the work we complete involves:

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

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

There’s also some work you can do by yourself between professional tune-ups. You only 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

Pick a temperate 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 few 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

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

2. Clean the Outside

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

Then turn on the vacuum to cautiously clean the metallic fins. These components are also known as condenser coils and transfer heat away from your system.

You need to be considerate of these delicate coils. Bent or crumpled fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to adjust misshapen fins. You can also get a fin comb from an appliance parts retailer. A pro from Wallpe Heating & Cooling should fix extensive damage.

4. Clean the Inside

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

The only coil cleaner you have to have is water. Use light pressure from a hose nozzle to clean the fins, showering 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 operating like it should, give us a call at 812-638-4232.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut the power to your furnace at the breaker box.

2. Check Your Filter

Furnace filters must be changed every couple of months, depending on the type you use.

Can’t remember when you last put in a new one? Pull it out 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 moldy, you can clean it by draining diluted bleach through the tube to clean 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.
