Tips for Cleaning Your AC System

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

If you haven’t cleaned it recently, it could be blocked with dirt and yard refuse. This collection can limit your unit’s efficiency and cause it to stop working. Or require replacement sooner.

We recommend 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 costs.

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

Some of the work we do involves:

  • Viewing the blower, motor, drain line and coils
  • Confirming pressure and temperature
  • Testing lines, refrigerant totals and connections

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

Schedule maintenance now


There’s also some maintenance you can do by yourself between professional tune-ups. You just need 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 wash your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is great. That way, you can check your system once you’ve cleaned it.

You’ll only need a few 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

Switch off the juice to your air conditioner at the breaker box.

2. Clean the Outside

Remove debris from the system. This includes branches, bushes, weeds and grass.

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

You need to be considerate of these fragile coils. Bent or crushed fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to adjust bent fins. You can also use a fin comb from an appliance parts store. A pro from Alan Energy Services Air Conditioning and Heating Company should take care of extensive damage.

4. Clean the Inside

After removing the fan, fish out leaves and other yard litter. Then wipe the inside of the unit with a wet rag.

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

5. Test Your Air Conditioner

You can now restore power and turn your air conditioner back on. If it’s not working correctly, contact us a call at 630-570-0252.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the power to your furnace at the breaker box.

2. Check Your Filter

Furnace filters need to be exchanged every couple of months, depending on the type you use.

Not sure when you last put in a new one? Remove it and hold it up to the light. If you can’t see light through it, 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 flexible plastic tube. If it’s scummy, you can clean it by flowing thinned bleach through the tube to sanitize the line. Or you can get a new tube.

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