Tips for Cleaning Your AC System

With summer coming to an end in Redford, now is a good time to get ahead on air conditioner maintenance.

If you haven’t washed it this year, it could be clogged with dirt and yard refuse. This collection can limit your unit’s efficiency and cause it to stop working. Or make it wear out faster.

We advise having your air conditioning system professionally serviced every year. Why? Clean equipment can be more energy efficient, which could save you money on electric bills.

Consistent AC maintenance also helps our technicians spot and address slight issues before they become high-priced problems.

Some of the work we do consists of:

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

You can still have service done this fall—and we can get your furnace prepped for heating season too.

There’s also some upkeep you can do alone between professional tune-ups. You only need 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

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

You’ll only need a few 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

Switch off 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 referred to as condenser coils and transfer heat away from your system.

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

3. Fix Bent Fins

Use a butter knife to adjust misshapen fins. You can also buy a fin comb from an appliance parts website. A pro from Airtronic Heating & Cooling should fix 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 have to have is water. Use slight pressure from a hose nozzle to clean the fins, directing water from the inside out. Reinstall the fan once you’re done.

5. Test Your Air Conditioner

It’s safe to restore power and turn your air conditioner back on. If it’s not working like it should, give us a call at 313-230-4053.

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 should be exchanged every several months, depending on the model you use.

Can’t remember when you last checked yours? Pull it out and hold it up to the light. If you can’t see light through it, replace it.

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 pliable plastic tube. If it’s moldy, you can sanitize it by flowing diluted bleach through the tube to flush the line. Or you can buy a new tube.

Scrub the drain port using a small, round paintbrush. Reconnect the drain tube and turn the power back on.
