Warranty
In the US 10-year parts, 10-year compressor
Registration: Base 5-year parts and 7-year compressor. The 10-year term needs an owner-occupied home and registration within 90 days at registermehvac.com; 12 years if a Diamond Contractor installs and registers it. Residents of California, Connecticut, Florida and Georgia need not register.
Labour: None: the statement “does NOT include labor”
For comparison: in Canada 10-year parts, 10-year compressor
60 months (5 years) parts and 84 months (7 years) compressor. The 10-year term (12 years for an approved FS combination) needs a MESCA Authorized (MEQ-trained) contractor and registration within 90 days. Quebec residents are not required to register.
Strengths and watch-outs
Strengths
- Longest registered US warranty in this group: 12-year parts and compressor when a Diamond Contractor installs and registers within 90 days (statement effective Feb 9, 2026)
- Deep cold-climate ratings: US H2i wall units rated 100% capacity at 5°F with operation to -22°F; Canadian FX rated 100% at -23°C (maker literature)
- Full residential range under one maker: ductless, SMART MULTI multi-zone, ducted air handlers, intelli-HEAT dual fuel and, from 2026, ecodan air-to-water
- US residential lineup moved to R-454B in 2025 (April 2025 release; ENERGY STAR R-454B listings for FX, GX, HX, JX, SUZ/PUZ and SMART MULTI)
Watch-outs
- 90-day registration window in both countries; unregistered systems get 5-year parts / 7-year compressor (exempt: CA, CT, FL, GA residents in the US; Quebec residents in Canada)
- Entry HM/WR/HX/WX wall-mount series have a separate US warranty capped at 10 years, with no 12-year Diamond tier (statement effective June 1, 2026)
- No labour cover from the maker; the US warranty transfers only with a home sale in Florida, Texas or Georgia, and the Canadian warranty is not transferable
- Co-branded Trane / Mitsubishi Electric and American Standard / Mitsubishi Electric units appear in ENERGY STAR only as R-410A listings, and R-410A PUMY 'S-Series' units were still certified for Canada in 2026: confirm the refrigerant on any quote
