Tips to Reduce Your AC Electricity Bills

🌡️ Smart Thermostat
A smart thermostat saves 10–15% on AC electricity by automatically raising the set temperature when you're asleep or away by automatically raising the set temperature when you're asleep or away. Ecobee and Nest are popular Canadian options, both listed on ENERGY STAR Canada's qualified smart thermostat database.
🪟 Window Coverings
Closing blinds and curtains on south- and west-facing windows during the hottest afternoon hours reduces solar heat gain by 20–30%, reducing how hard your AC must work.
🌀 Ceiling Fans
Ceiling fans create a wind-chill effect that lets you raise your thermostat set-point by 2°C without feeling warmer — reducing AC runtime and cutting electricity use by 8–10%.
🗂️ Clean Filters Monthly
A clogged air filter reduces airflow, forcing the AC to run longer and harder. Cleaning or replacing your filter monthly during cooling season can reduce electricity use by 5–10%.

Questions & Answers of AC Operating Cost

How do I calculate my AC's electricity cost?

Multiply tonnage × 12,000 BTU ÷ SEER2, then × daily run hours × your electricity rate — our calculator does this instantly with your real numbers.

Variable-speed ductless mini-splits from Mitsubishi Electric Canada, Daikin, and Fujitsu reach up to 30+ SEER2 for single-zone systems, while top central AC systems hit around 26 SEER2 cutting electricity use up to 50% over minimum-efficiency units.

Usual causes are an oversized unit short-cycling, low refrigerant, dirty coils, or duct leaks compare your bill to our calculator's estimate to spot which one.
