How to compare quotes
| Check | Why it matters |
|---|---|
| Heat-loss calculation | Proves the size is right for your home |
| Exact model numbers (outdoor + indoor) | Needed for rebates and to compare performance |
| Capacity at −15 °C | Tells you how it performs when it counts |
| Backup heat plan | What runs on the coldest nights, and what it costs |
| Electrical & permits included | Avoids surprise extras |
| Warranty: parts and labour | Labour coverage varies a lot between installers |
| Rebate help | Who handles pre-approval and paperwork |
On installation day
- Clear a path to the furnace room and outdoor location
- Expect heating or cooling to be off for part of the day
- The crew mounts the outdoor unit, runs refrigerant lines and wiring, and connects the indoor side
- They pressure-test and evacuate the lines before charging refrigerant
- You get a walkthrough of the thermostat and settings
After it’s installed
- Register your warranty
- Keep documents for the rebate submission
- Change or clean filters every 1–3 months
- Keep the outdoor unit clear of snow, leaves and debris
- Book annual maintenance

Common questions
Will I be without heat?
Installers usually schedule so you’re without heating or cooling for only part of a day. In deep winter, ask about temporary heat.
How long does the rebate take after installation?
The rebate comes as a cheque in the mail. Processing times vary by program; submitting complete documents promptly is the best way to avoid delays.
