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.
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.
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.
Think about upgrading if:
Rooms served by your air conditioner are too hot
Your system is more than 10 years old
It's unusually noisy
Your home's airis too humid
You need major parts replaced
Central air conditioners are more efficient than room air conditioners.
When it comes to hiringa contractor, it pays todo your homework.Here's how to bebetter prepared.
Book a spring tune-up
Annual servicing can reduce your cooling costs by up to 10% and extend the life of your system.
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.
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.
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.
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.
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.
Let your attic breathe
Proper attic ventilation can reduce the strain on your central air conditioner by moving hot air out.
Switch on the fans
Remove heat and humidity by using your bathroom fan after a shower and your range hood while cooking.
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.
Close the blinds
Keep blinds and curtains closed during the day to block out the sunlight and naturally cool your home.
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.
* Assumes replacement of a model 12 years or older.
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.
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.
