Warranty

In Canada 10-year parts, 10-year compressor

Registration: The Rheem Sales Company certificate covers US and Canadian installations; ruud.ca publishes no separate Canadian terms and no Quebec rules were found.

Labour: Not covered by the limited warranty.

Warranty terms (ruud.ca) ↗

For comparison: in the US 10-year parts, 10-year compressor

Same Rheem Sales Company certificate as Rheem: register within 90 days of installation (or closing) for conditional terms; otherwise shorter non-registered terms apply (e.g., 5-year parts on entry models). UP19AY lists 10-year parts plus a 10-year Conditional Unit Replacement (registration required); RD18AY lists 10-year conditional parts (registration required). Floating Air ductless: 7-year parts unregistered, 10 registered, 10-year compressor (per the shared Floating Air certificate).

Strengths and watch-outs

Strengths

Same Rheem-built Endeavor platform as Rheem under different series names, including the RD18AY universal heat pump (up to 10.0 HSPF2)
Floating Air Ultra ductless: heating down to -22°F single-zone with full capacity claimed at 5°F (ruud.com)
UP19AY: 10-year parts plus 10-year conditional unit replacement with registration (product page)
Sold in both the US and Canada (ruud.com, ruud.ca)

Watch-outs

90-day registration window for the conditional (10-year) terms
ruud.com still lists the R-410A RD17AZ and other 'AZ' models beside R-454B 'AY' models; confirm refrigerant on quotes
Series names differ from Rheem's for identical model numbers (Ultra = Prestige, Achiever Plus = Classic Plus, Achiever = Classic, Choice = Select), which complicates comparisons

Which rebates Ruud models fit

33 Ruud outdoor models meet the cold-climate numbers NRCan publishes for its Eligible Products List (COP of at least 1.8 at −15°C at full output, 70% of rated capacity, a variable-speed compressor) on their ENERGY STAR ratings. That list decides Ontario's Home Renovation Savings rebate, Manitoba's, New Brunswick's, Yukon's and Newfoundland and Labrador's, and the federal National Heat Pump Rebate expected in early 2027. Check the exact pairing on NRCan's list ↗.

56 models meet ENERGY STAR Cold Climate, which earns Quebec's higher LogisVert rate. BC uses its own qualified list. Rebate rules by province:

Ontario Quebec British Columbia Alberta Manitoba Saskatchewan Nova Scotia New Brunswick Newfoundland & Labrador Prince Edward Island The North (YT · NT · NU)
