Tips for Cleaning Your AC System

With summer ending in Moline, now is a great time to get a kick start on air conditioner maintenance.

If you haven’t washed it recently, it could be clogged with dust and yard refuse. This collection can decrease your unit’s efficiency and cause it to break down. Or make it wear out sooner.

We advise having your air conditioning system professionally tuned-up once a year. Why? A clean system can be more energy efficient, which could save you money on energy expenses.

Consistent AC maintenance also helps our technicians spot and handle small issues before they turn into expensive problems.

Some of the work we perform includes:

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

It’s not too late to have service done this fall—and we can get your furnace prepared for heating season too.

There’s also some maintenance you can do alone between professional tune-ups. It only takes about an hour to clean your outdoor condenser unit, as well as a couple of parts 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 great. That way, you can run your system 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 power to your air conditioner at the breaker box.

2. Clean the Outside

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

Then run the vacuum to slowly clean the metallic fins. These parts are also referred to as condenser coils and move heat away from your equipment.

You need to be cautious with these delicate coils. Warped or crushed fins can impact 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 Freed Heating & Air Conditioning should fix 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 slight pressure from a hose nozzle to wash the fins, spraying water from the inside out. Replace the fan 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 running properly, give us a call at 309-323-9584.

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 should be changed every several months, depending on the type you use.

Unsure when you last put in a new one? Take it out and tilt it toward the light. If light isn’t visible, replace it.

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 clean it by draining diluted bleach through the tube to sanitize the line. Or you can get a new tube.

Clean the drain port using a small, round paintbrush. Hook up the drain tube and restore power.
