When temperatures rise, so do hydro bills.
Your A/C becomes one of the biggest energy users in your home during the summer months—but staying cool doesn’t have to mean overspending. With a few simple adjustments, you can keep your home comfortable while keeping your energy costs under control.
Here are practical cooling tips that actually make a difference:
Lower isn’t always better.
Setting your thermostat too low won’t cool your home faster—it just makes your system run longer.
Aim for a consistent, comfortable temperature (around 24–26°C when you’re home). When you’re away, raise it a few degrees to reduce unnecessary usage.
A programmable or smart thermostat can help automate this and improve efficiency.
Fans don’t cool the air—but they help circulate it.
Air movement helps you feel cooler, meaning you can set your thermostat a few degrees higher without sacrificing comfort.
Use ceiling or portable fans in occupied rooms. Just remember to turn them off when you leave—they cool people, not spaces.
Sunlight through windows can quickly heat up your home.
The harder your A/C has to work to offset heat gain, the more energy it uses.
A dirty filter is one of the easiest ways to waste energy. Restricted airflow makes your system work harder and less efficiently.
Check your filter monthly during the summer and replace it as needed (typically every 1–3 months).

Cool air escaping = wasted money.
Gaps around windows and doors allow conditioned air to leak out and hot air to enter. Check for drafts and seal them with weatherstripping or caulking to keep cool air inside where it belongs.
Lowering your hydro bill isn’t about one big change—it’s about a few smart habits that add up. By improving efficiency and reducing unnecessary usage, you can stay comfortable without overworking your system.
