Canadian weather is trending hotter while electricity prices climb, making it tough to keep your house cool without blowing the budget. The good news? We have ten energy-efficient ways to cool your home in the summer heat, either for free, at a low cost or as a one-time investment upgrade. You’ll stay comfortable, trim your carbon footprint, and lower electric bills all season long.
Whenever you’re ready for professional help, the friendly experts at ClimateCare can fine-tune, repair, or upgrade your system for substantial savings.
1. Dial In Your Thermostat
Set your thermostat to about 24 °C when you’re home for comfort without being too cold and bump it 2-3 °C higher when you’re out. A smart or programmable thermostat can handle those adjustments automatically and even work with local time-of-use rates to run cooling during cheaper periods. Now that’s an effortless way to slash costs.
2. Maximize Fan Power
Ceiling fans set counter-clockwise create a breeze that feels roughly 4 °C cooler on your skin, letting you nudge the thermostat up without sacrificing comfort. Don’t have central AC? Don’t worry! At night, place a box fan in a window on one side of the house and open another window opposite to pull in cool air for free.
3. Block Solar Heat Gain
Close blinds or use blackout curtains, especially in south- and west-facing windows, between 10 a.m. and 4 p.m. when the sun is at its highest. If heat is still building up indoors, add reflective window film or exterior shutters. Both cut out radiant heat before it ever enters your living space.
4. Seal & Insulate
Weather-strip doors, caulk window gaps, and make sure attic insulation meets today’s R-value* standards. Fewer leaks mean less hot air sneaking in and less cool air leaking out, easing the load on your AC or heat pump.
*R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value, the better the thermal performance.
5. Service & Upgrade Cooling Equipment
A yearly tune-up keeps filters clean, coils shining, refrigerant levels high, and airflow strong; small investments that recoup big savings in efficiency.
If you have an older AC, consider upgrading to something more powerful and efficient. Using equipment with multiple stages of cooling allows for more consistent comfort than single-stage equipment that only has On and Off modes. If you don’t have a centrally ducted home, there’s no issue. Ductless heat pumps also act as air conditioners and provide the same benefits as a central AC on a zone-by-zone basis.

6. Reduce Indoor Heat Sources
Large ovens, incandescent bulbs, and long hot showers add a surprising amount of heat. Summer is the perfect time to fire up the grill. Hot dogs, hamburgers, steaks and kebabs on the BBQ are essential ingredients of summer, and keep the heat from cooking outside— where it belongs!
For indoor prep, make shorter, cooler showers part of your daily routine, lean on microwaves, air fryers, toaster ovens, and instant pots, and swap every remaining incandescent for cool-running LEDs.
7. Control Humidity
High humidity makes 25 °C feel like 30 °C. Run bathroom and range-hood fans that vent outdoors, switch your heat pump or AC to “dry” mode on sticky days, or add a stand-alone dehumidifier to basements. Drier air lets you dial the thermostat higher and still feel refreshed.
8. Harness Night & Passive Cooling
When evening temperatures dip below indoor temps, open upper and lower windows to create a chimney effect that flushes out warm air. In drier climates, hanging a damp sheet in front of an open window speeds evaporation for a few extra degrees of free cooling.
9. Shade the Exterior
Plant deciduous trees on the south, east, and west sides of your home to block the high summer sun yet let winter light through. Pergolas, awnings, or exterior solar shades over southern windows can slash solar heat gain by up to 65%.
10. Track & Tweak Energy Habits
An inexpensive real-time electricity monitor shows exactly when and where power spikes. You’ll spot surprises—like a computer that never sleeps—and fix them fast.
For inexpensive maintenance you can do, set monthly reminders to replace or wash HVAC filters. If the filter becomes very clogged, it can even cause your system to stop working by freezing the evaporator coil. Proper airflow is essential!
