Tips for Cleaning Your AC System

September 20, 2019

With summer ending in Huntingburg, now is an ideal time to get a head start on air conditioner maintenance.

If you haven’t taken care of it lately, it could be blocked with dirt and yard waste. This accumulation can decrease your unit’s efficiency and cause it to break down. Or make it wear out more quickly.

We suggest having your air conditioning system professionally tuned-up annually. Why? Clean equipment can be more energy efficient, which could save you money on electric bills.

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

Some of the work we do consists of:

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

It’s not too late to have a tune-up done this fall—and we can get your furnace prepared 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 wash your outdoor condenser unit, as well as a few components on your indoor HVAC system.

How to Clean Your Outside AC Unit

Pick a mild day to wash 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 handful 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

Stop 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 run the vacuum to cautiously clean the metallic fins. These parts are also called as condenser coils and divert heat away from your equipment.

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

3. Fix Bent Fins

Use a butter knife to straighten warped fins. You can also buy a fin comb from an appliance parts store. A pro from Dearing's Service & Solutions should take care of severe damage.

4. Clean the Inside

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

The only coil cleaner you should use is water. Use light pressure from a hose nozzle to rinse the fins, directing water from the inside out. Put the fan back in once you’re completed.

5. Test Your Air Conditioner

It’s safe to restore power and turn your air conditioner back on. If it’s not running correctly, give us a call at 812-200-5844.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the electricity to your furnace at the breaker box.

2. Check Your Filter

Furnace filters need to be changed every few months, depending on the model you use.

Unsure when you last replaced yours? Take it out and angle it toward 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 flexible plastic tube. If it’s dirty, you can freshen it by draining water-down bleach through the tube to sanitize 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.
