Tips for Cleaning Your AC System in Wisconsin Rapids

With summer coming to an end in Wisconsin Rapids, now is an ideal time to get ahead on air conditioner maintenance.

If you haven’t taken care of it lately, it could be full of dirt and yard waste. This collection can limit your unit’s efficiency and cause it to stop working. Or make it wear out more quickly.

We advise having your air conditioning system professionally tuned-up once a year. Why? Clean equipment can be more energy efficient, which could save you money on utility bills.

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

There’s also some work you can do alone between professional tune-ups. You only need about an hour to get the grime off your outdoor condenser unit, as well as a few parts on your indoor HVAC system.

How to Clean Your Outside AC Unit

Pick a warm day to scrub your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is best. That way, you can test your system once you’ve cleaned it.

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

2. Clean the Outside

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

Then use the vacuum to slowly clean the metallic fins. These parts are also known as condenser coils and transfer heat away from your equipment.

You need to be considerate of these fragile coils. Bent or crushed fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to adjust bent fins. You can also get a fin comb from an appliance parts website. A pro from Rapids Sheet Metal Works Inc should fix severe damage.

4. Clean the Inside

After taking out the fan, pull out leaves and other yard waste. Then clean the inside of the equipment with a wet sponge.

The only coil cleaner you should use is water. Use gentle pressure from a hose nozzle to wash the fins, directing water from the inside out. Reinstall the fan once you’re finished.

5. Test Your Air Conditioner

Now it’s time to restore power and turn your air conditioner back on. If it’s not working properly, contact us a call at 715-301-0256.

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

Can’t remember when you last replaced 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 supple plastic tube. If it’s scummy, you can sanitize it by pouring diluted bleach through the tube to sanitize the line. Or you can replace the tube.

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