Tips for Cleaning Your AC System in Carpentersville

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

If you haven’t cleaned it lately, it could be blocked with mud and yard waste. This buildup can limit your unit’s efficiency and cause it to stop working. Or wear it down sooner.

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

Consistent AC maintenance also helps our technicians spot and handle minor issues before they turn into high-priced problems.

There’s also some work you can do by yourself between professional tune-ups. You only need about an hour to wash your outdoor condenser unit, as well as several parts on your indoor HVAC system.

How to Clean Your Outside AC Unit

Select a warm day to clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can check the unit once you’ve cleaned it.

You’ll only need a handful of 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 power to your air conditioner at the breaker box.

2. Clean the Outside

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

Then turn on the vacuum to gently clean the metallic fins. These components are also known as condenser coils and move heat away from your unit.

You need to be careful with these delicate coils. Warped or crumpled fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to straighten bent fins. You can also buy a fin comb from an appliance parts website. A pro from Controlled Comfort HVAC Inc should take care of extensive damage.

4. Clean the Inside

After extracting the fan, fish out leaves and other yard litter. Then clean the inside of the system with a wet rag.

The only coil cleaner you have to have is water. Use slight pressure from a hose nozzle to rinse 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 running properly, give us a call at 224-699-9229.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut the juice to your furnace at the breaker box.

2. Check Your Filter

Furnace filters must be replaced every few months, depending on the type you use.

Can’t remember when you last checked yours? 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 flexible plastic tube. If it’s moldy, you can clean it by flowing 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. Reconnect the drain tube and turn the power back on.
