Tips for Cleaning Your AC System in Middletown

With summer winding down in Middletown, now is an ideal 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 accumulation can reduce your unit’s efficiency and cause it to malfunction. Or make it wear out more quickly.

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 utility bills.

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

There’s also some maintenance you can do on your own between professional tune-ups. It only takes about an hour to get the grime off your outdoor condenser unit, as well as a few pieces 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 run your system once you’ve cleaned it.

You’ll only need a couple of things:

  • 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 power to your air conditioner at the breaker box.

2. Clean the Outside

Take out debris from the system. 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 transfer heat away from your unit.

You need to be considerate of these delicate coils. Bent or crinkled fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange bent fins. You can also use a fin comb from an appliance parts website. A pro from Schagrin Gas Company should take care of large amounts of damage.

4. Clean the Inside

After removing the fan, pull out leaves and other yard waste. Then clean the inside of the equipment with a wet cloth.

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

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not working properly, give us a call at 302-231-1380.

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 exchanged every few months, depending on the kind you use.

Unsure when you last checked yours? Pull it out and hold it up to the light. If light isn’t visible, buy 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 scummy, you can freshen it by draining diluted bleach through the tube to sanitize the line. Or you can get a new tube.

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