Warranty
Registration: The 10-year parts warranty (including the compressor) still applies. On VXP systems, registering within 60 days gives a first-year compressor-failure unit credit plus a $300 labour allowance; unregistered units get it only for failures within 90 days of purchase.
Labour: Not covered, apart from the $300 allowance with a compressor-failure credit (VXP)
Same US/Canada terms: on VXP, the first-year compressor credit shrinks to 90 days if the unit isn't registered within 60 days
Strengths and watch-outs
Strengths
- 10-year parts warranty including the compressor on current VXP and VHP lines, valid in the US and Canada
- Very broad range from one maker: cold-weather ducted (VXP, operation to -22°F), ultra-efficient ductless (ZHP up to 35 SEER2), packaged, window, PTAC and geothermal
- Long-established maker (Heat Controller cites nearly 100 years in HVAC)
Watch-outs
- Labour isn't covered beyond a $300 allowance on some compressor claims
- VHP warranty is void for units bought over the internet, and coverage requires a complete matched system
- Register VXP systems within 60 days to keep the first-year compressor replacement credit
- Some listed lines (e.g., VCD) still use R-410A; the US no longer allows new R-410A split systems, so confirm the refrigerant on any quote
