Tips for Cleaning Your AC System in Ontario

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

If you haven’t taken care of it lately, it could be clogged with dust and debris from your yard. This collection can reduce your unit’s efficiency and cause it to break down. Or require replacement sooner.

We recommend having your air conditioning system professionally tuned-up once a year. Why? A clean unit can be more energy efficient, which could save you money on energy costs.

Consistent AC maintenance also helps our technicians spot and handle slight issues before they develop into expensive problems.

Some of the work we complete includes:

  • Viewing the blower, motor, drain line and coils
  • Confirming pressure and temperature
  • Reviewing lines, refrigerant amounts and connections

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

There’s also some upkeep you can do on your own between professional tune-ups. You just need about an hour to clean your outdoor condenser unit, as well as several pieces on your indoor HVAC system.

How to Clean Your Outside AC Unit

Choose a temperate day to clean your air conditioner. At least 60 degrees Fahrenheit (20 degrees Celsius) is ideal. That way, you can run your equipment once you’ve cleaned it.

You’ll only need a handful of items:

  • 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

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

Then use the vacuum to cautiously clean the metallic fins. These components are also referred to as condenser coils and transfer heat away from your equipment.

You need to be cautious with these fragile coils. Warped or crushed fins can influence efficiency.

3. Fix Bent Fins

Use a butter knife to straighten misshapen fins. You can also get a fin comb from an appliance parts store. A pro from Stan's Heating, Inc should take care of large amounts of damage.

4. Clean the Inside

After removing the fan, pull out leaves and other yard litter. Then mop the inside of the unit with a wet cloth.

The only coil cleaner you need 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 finished.

5. Test Your Air Conditioner

It’s safe to restore power and turn your air conditioner back on. If it’s not working like it should, reach out to us a call at 541-286-6602.

3 Steps to Clean the Indoor Unit

1. Turn Off the Power

Turn off the electricity to your furnace at the breaker box.

2. Check Your Filter

Furnace filters should be changed every several 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 pliable plastic tube. If it’s scummy, you can clean it by draining diluted bleach through the tube to sanitize the line. Or you can get a new tube.

Wash the drain port using a small, round paintbrush. Reconnect the drain tube and restore power.
