Tips for Cleaning Your AC System

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

If you haven’t washed it this year, it could be clogged with dirt and yard waste. This collection can limit your unit’s efficiency and cause it to malfunction. Or wear it down sooner.

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 utility expenses.

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

Some of the work we perform includes:

  • Taking a look at the blower, motor, drain line and coils
  • Confirming pressure and temperature
  • Reviewing lines, refrigerant levels and connections

It’s not too late to have a tune-up 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 couple of components on your indoor HVAC system.

How to Clean Your Outside AC Unit

Choose a temperate day to scrub your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can run the unit 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

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

Then run the vacuum to gently clean the metallic fins. These pieces are also referred to as condenser coils and divert heat away from your equipment.

You need to be cautious with these delicate coils. Bent or crumpled fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to straighten warped fins. You can also get a fin comb from an appliance parts store. A pro from Gee & Missler Heating & Air Conditioning should handle severe damage.

4. Clean the Inside

After extracting the fan, dig out leaves and other yard rubbish. Then mop the inside of the equipment with a wet rag.

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

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not working like it should, give us a call at 734-363-8907.

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 should be exchanged every couple of months, depending on the kind you use.

Unsure when you last checked yours? Take it out and angle it toward the light. If light isn’t visible, replace it.

3. Clean the Inside

Remove the blower door and vacuum up dust.

Then examine your air conditioner’s drain line—it’s a flexible plastic tube. If it’s dirty, you can sanitize it by pouring thinned bleach through the tube to clean the line. Or you can buy a new tube.

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