Tips for Cleaning Your AC System

With summer winding down in Savage, now is an ideal time to get ahead on air conditioner maintenance.

If you haven’t washed it recently, it could be full of dust and yard refuse. This collection can reduce your unit’s efficiency and cause it to stop working. Or make it wear out sooner.

We suggest having your air conditioning system professionally serviced annually. Why? A clean system can be more energy efficient, which could save you money on utility costs.

Routine AC maintenance also helps our technicians spot and take care of minor issues before they develop into costly problems.

Some of the work we perform includes:

  • Taking a look at the blower, motor, drain line and coils
  • Checking pressure and temperature
  • Testing lines, refrigerant amounts and connections

There’s still time to have service done this fall—and we can get your furnace prepped for heating season too.

There’s also some work you can do alone between professional tune-ups. It only takes about an hour to wash your outdoor condenser unit, as well as several pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

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

You’ll only need a handful of 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 components are also referred to as condenser coils and transfer heat away from your unit.

You need to be cautious with these fine coils. Misshapen or crinkled fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange warped fins. You can also use a fin comb from an appliance parts retailer. A pro from Gopher Heating and Air Conditioning should fix severe damage.

4. Clean the Inside

After removing the fan, dig out leaves and other yard litter. Then clean the inside of the unit with a wet sponge.

The only coil cleaner you have to have is water. Use slight pressure from a hose nozzle to wash the fins, showering water from the inside out. Reinstall the fan once you’re completed.

5. Test Your Air Conditioner

You can now restore power and turn your air conditioner back on. If it’s not running like it should, reach out to us a call at 952-373-0377.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Cut the power to your furnace at the breaker box.

2. Check Your Filter

Furnace filters must be changed every couple of months, depending on the model you use.

Not sure when you last checked yours? Remove it and angle it toward the light. If there’s no light 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 sanitize it by draining water-down bleach through the tube to flush the line. Or you can replace the tube.

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