Tips for Cleaning Your AC System

With summer winding down in Winnipeg, now is a great time to get a head start on air conditioner maintenance.

If you haven’t taken care of it this year, it could be full of dust and yard waste. This buildup can limit your unit’s efficiency and cause it to stop working. Or wear it down more quickly.

We suggest having your air conditioning system professionally maintained once a year. Why? Clean equipment can be more energy efficient, which could save you money on electric expenses.

Consistent AC maintenance also helps our technicians spot and take care of small issues before they develop into expensive problems.

Some of the work we perform consists of:

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

There’s still time to have maintenance 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 just 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

Select a mild day to clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can check 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

Stop the electricity to your air conditioner at the breaker box.

2. Clean the Outside

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

Then run the vacuum to gently clean the metallic fins. These components are also known as condenser coils and transfer heat away from your unit.

You need to be cautious with these delicate coils. Warped or crumpled fins can impact efficiency.

3. Fix Bent Fins

Use a butter knife to adjust bent fins. You can also use a fin comb from an appliance parts store. A pro from Kirkfield Heating & Air Conditioning should fix large amounts of damage.

4. Clean the Inside

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

The only coil cleaner you have to have is water. Use light pressure from a hose nozzle to rinse the fins, directing water from the inside out. Replace the fan once you’re finished.

5. Test Your Air Conditioner

It’s safe to restore power and turn your air conditioner back on. If it’s not running properly, give us a call at 204-272-8128.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Stop the electricity to your furnace at the breaker box.

2. Check Your Filter

Furnace filters need to be exchanged every couple of months, depending on the type you use.

Unsure when you last put in a new one? Take it out and angle it toward 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 inspect your air conditioner’s drain line—it’s a supple plastic tube. If it’s moldy, you can sanitize it by flowing water-down bleach through the tube to flush the line. Or you can buy a new tube.

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