Tips for Cleaning Your AC System

With summer coming to an end in Menomonie and western Wisconsin, now is a good time to get a kick start on air conditioner maintenance.

If you haven’t taken care of it recently, it could be clogged with mud and debris from your yard. This accumulation can limit your unit’s efficiency and cause it to malfunction. Or wear it down more quickly.

We suggest having your air conditioning system professionally tuned-up every year. Why? A clean unit can be more energy efficient, which could save you money on utility bills.

Regular AC maintenance also helps our technicians locate and take care of minor issues before they become expensive problems.

Some of the work we do involves:

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

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

There’s also some maintenance you can do alone between professional tune-ups. It only takes about an hour to get the grime off your outdoor condenser unit, as well as a few components 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 best. That way, you can check your equipment 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

Cut the juice to your air conditioner at the breaker box.

2. Clean the Outside

Take out debris from the equipment. This includes branches, bushes, weeds and grass.

Then use the vacuum to cautiously clean the metallic fins. These parts are also known as condenser coils and move heat away from your system.

You need to be considerate of these delicate coils. Bent or crumpled fins can affect efficiency.

3. Fix Bent Fins

Use a butter knife to rearrange misshapen fins. You can also use a fin comb from an appliance parts retailer. A pro from Halverson Brothers Inc should handle extensive damage.

4. Clean the Inside

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

The only coil cleaner you need is water. Use gentle pressure from a hose nozzle to clean the fins, spraying water from the inside out. Replace the fan once you’re completed.

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not operating correctly, give us a call at 715-352-4052.

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 changed every couple of months, depending on the kind you use.

Not sure when you last replaced yours? Pull it out and tilt it toward the light. If light isn’t visible, buy a new one.

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 freshen it by draining water-down bleach through the tube to clean the line. Or you can get a new tube.

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