Soaring temperatures can have us rushing to lower the thermostat, but instead of blasting the air conditioner, check out these resources, rebates and natural cooling tips to help cool your home as efficiently as possible. You'll stay comfortable while controlling your costs.


Au naturel:
Home ventilation

Of all the ways to cool your home, ventilation is the least costly and most energy efficient.

  1. Stylized number 1

    Install a ceiling fan

    A ceiling fan allows you to raise your thermostat by 4°C without affecting your comfort. Set blades to run in a counter-clockwise direction to circulate cool air downwards. Download a coupon for $10 off ENERGY STAR® certified ceiling fans.

  2. Stylized number 2

    Create a cross breeze

    Open a few windows to create cross ventilation. For the best results, open a lower window on one side of your home and an upper window on the opposite side.

Working with
a contractor

When it comes to hiring
a contractor, it pays to
do your homework.
Here's how to be
better prepared.

Choosing a contractor

  • Start with our list of participating contractors near you
  • Read online reviews
  • Ask friends and neighbours for recommendations (check to ensure they're on the list of participating contractors)
  • Get at least three quotes and compare estimates
  • Ask for an inspection of your current system
  • Get everything in writing
  • Ask about rebates for high-efficiency systems
  • Ensure your contractor has general liability insurance to protect yourself
  • Ask about services post-installation, including annual servicing, maintenance, etc.

10 ways
to cool
your home efficiently

Tip #1

Book a spring tune-up

Annual servicing can reduce your cooling costs by up to 10% and extend the life of your system.

Tip #2

Change or clean furnace filters

Clogged filters restrict airflow and make your system work overtime. Refer to your owner's manual to see how often you should do this.

Tip #3

Deal with your ducts

About 20% of airflow is lost to leaks. Seal cracks and holes with mastic sealant or foil tape – this will also help control humidity.

Tip #4

Clear away clutter

Keep weeds and debris away from your outdoor condenser unit to allow the air to circulate freely. Prune foliage at least 24 cm back.

Tip #5

Set to save

Set your thermostat to 25°C when you're at home. Raise it to 28°C (or, better yet, off) when you're away.

Tip #6

Shade to save

Plant trees or shrubs to shade your outdoor condenser and improve efficiency by up to 10%. Keep your thermostat out of direct sunlight as well.

Tip #7

Let your attic breathe

Proper attic ventilation can reduce the strain on your central air conditioner by moving hot air out.

Tip #8

Switch on the fans

Remove heat and humidity by using your bathroom fan after a shower and your range hood while cooking.

Tip #9

Seal the leaks

Caulk, seal or weatherstrip around doors and windows to keep hot air out and cool air in. Download a coupon for $3 off weatherstripping.

Tip #10

Close the blinds

Keep blinds and curtains closed during the day to block out the sunlight and naturally cool your home.

Shopping for
a central air conditioner?

An ENERGY STAR® certified high-efficiency model can cut cooling costs as much as 30%*. While you may pay a little more up front, you'll save on energy costs over time.

Added benefits:

  • Proven reliability
  • Quiet performance
  • Better warranty protection
  • Improved air quality
  • Use less energy

* Assumes replacement of a
model 12 years or older.


Look for the labels

The official Canadian EnerGuide label displays the model type and seasonal energy efficiency ratio or SEER. The SEER measures how efficiently the system runs over the entire cooling season. The higher the rating, the more efficient the system. You can use this rating to compare the energy efficiency of different models.

The most energy-efficient units will also be ENERGY STAR® certified.

Cool tip:
Double up
and save

Your central air conditioner and furnace share a blower motor to push air through your ducts. If it's about time to replace both your heating and cooling systems, your new AC will perform at maximum efficiency if you do it at the same time.


With rebates that help offset the upfront cost, now's the time to think about upgrading.
