Cooling Myths That Are Costing Canadian Homeowners Money

Cooling/AC

If you’re trying to stay cool during a Canadian summer, you’re not alone. But between rising hydro costs and sudden heat waves, many homeowners are unknowingly following outdated cooling advice—and it’s costing them. Whether you’re in a condo, a detached home, or a townhouse, these common cooling myths could be pushing your energy bills higher and shortening the life of your AC.

Are common cooling myths making your energy bills higher?

Many Canadian homeowners are still relying on old tips and tricks that don’t actually work—and in some cases, do more harm than good. Wondering which habits are costing you the most? Let’s break them down.

Myth 1: Cranking the Thermostat Will Cool Your Home Faster

Reality: Your air conditioner cools at a steady rate. Setting it to 16°C won’t cool faster than 22°C—it’ll just run longer and use more electricity.
Instead: Set your thermostat to a consistent temperature (around 23°C). Want to walk into a cool home after work or errands? A smart thermostat can learn your schedule and adjust automatically.

Myth 2: Turning Off the AC During the Day Saves Energy

Reality: Completely shutting off your AC while you’re out can increase your energy use. Your system has to work harder to cool a hot, stuffy house when you return.
Instead: Set the thermostat 4–6°C higher while you’re away. If you’re worried about efficiency, programmable thermostats make temperature control easy and automatic.

Myth 3: Fans Cool the Room

Reality: Fans cool people—not rooms. They create a wind-chill effect, but they don’t lower the actual air temperature.
Instead: Use fans only when you’re in the room, and turn them off when you leave. For better whole-home comfort, consider optimizing your home ventilation system or checking for airflow issues.

Myth 4: Closing Vents in Unused Rooms Saves Energy

Reality: Closing vents can disrupt your HVAC system’s airflow, increase duct pressure, and even cause damage.
Instead: Keep all vents open for balanced airflow. If you want more control over different zones or floors, ask about zoned HVAC systems or ductless cooling options.

Myth 5: You Only Need AC Maintenance When Something Breaks

Reality: Air conditioners in Canada sit unused for half the year. When they’re suddenly pushed to work hard in summer, hidden issues like dirty coils, clogged filters, or low refrigerant can lead to breakdowns.
Instead: Schedule annual AC maintenance to improve performance, reduce the risk of mid-summer breakdowns, and lower energy bills.
A1 Air Conditioning & Heating offers thorough AC tune-ups  that keep your system running at its best—especially before peak heat sets in.

How can I reduce my AC bill without sacrificing comfort?

Turning off your air conditioner completely might sound like a money-saver, but it can force your system to work overtime later. Smart temperature adjustments, clean filters, and regular tune-ups can go a long way in cutting energy use without sacrificing comfort.

How to Lower Cooling Costs Without Sacrificing Comfort:
  • Install a smart thermostat
  • Schedule AC tune-ups every spring
  • Keep vents and filters clean
  • Use ceiling fans efficiently
  • Insulate windows and seal drafts
  • Upgrade outdated equipment for energy-efficient alternatives
