Estimating how much electricity your mini-split heat pump draws—and what it costs—can help Montreal homeowners manage bills during frigid winters and warm summers. Climate Solutions, serving the Greater Montreal area since 2013, shows you how to turn your SEER2 and HSPF2 ratings into real-world expense figures.
Understanding SEER2 Ratings in Montreal Homes
The SEER2 (Seasonal Energy Efficiency Ratio 2) value indicates how efficiently a ductless mini-split cools your space. A higher SEER2 rating means lower power consumption for the same cooling output—essential in Montreal’s mixed climate where you need reliable performance through heat waves and muggy summers.
How to Estimate Annual Cooling Costs
Use this formula to get a ballpark figure for your cooling expenses:
Annual Cost = (BTU ÷ SEER2) × (Annual Run Hours ÷ 1 000) × Electricity Rate
- BTU: Unit’s cooling capacity (e.g., 12 000 BTU).
- SEER2: Efficiency rating from the manufacturer.
- Annual Run Hours: Total hours of use per year (cooling season).
- Electricity Rate: Cost per kWh—Hydro-Québec customers pay around CA$0.10/kWh.
Sample Cooling Calculation
Assume a 12 000 BTU mini-split runs 12 hours/day over 4.5 months (~1620 hours), with a SEER2 of 20:
- Annual Run Hours: 4.5 months × 30 days/month × 12 hours/day = 1620 hours
- Cost = (12 000 ÷ 20) × (1620 ÷ 1000) × 0.10 = CA$97.20
If the SEER2 were 18 instead, cost = (12 000 ÷ 18) × (1620 ÷ 1000) × 0.10 ≈ CA$108.00.
Heating Cost with HSPF2 Values
For heating, replace SEER2 with HSPF2 (Heating Seasonal Performance Factor 2). Higher HSPF2 means more heat per kWh in cold Montreal winters.
- Example: HSPF2 = 8.5, used 12 hours/day for 3 months (≈1080 hours).
- Cost = (12 000 ÷ 8.5) × (1080 ÷ 1000) × 0.10 ≈ CA$152.47
Practical Tips to Lower Your HVAC Bills
- Schedule annual maintenance with Climate Solutions to keep efficiency high.
- Install a programmable thermostat and adjust setbacks when you’re away.
- Seal ducts and insulate walls to reduce heat loss in winter.
- Opt for professional heat pump installation in Montreal to ensure correct sizing.
