Warranty
Registration: Conditional terms need registration within 90 days of installation (or home closing); unregistered units get shorter 'non-registered' terms, e.g., 5-year parts on Select and Classic models. Floating Air ductless: 7-year parts (10 if registered), 10-year compressor either way. Where offered (e.g., Prestige RP19AY), the 10-year Conditional Unit Replacement needs registration, and Rheem's certificate adds conditions such as a matched new Rheem indoor unit, a designated EcoNet thermostat and district pre-approval. Florida installs keep full terms without registration.
Labour: Not covered by the limited warranty; labour only through a contractor labour agreement or a Protection Plus extended service plan.
Rheem's certificate covers equipment installed in the US or Canada (Canadian owners pay shipping to return failed parts); registration is via rheem.registermyunit.ca. rheem.ca publishes no separate Canadian terms, so the US/Canada certificate's non-registered terms presumably apply; no Quebec-specific rules were found.
Strengths and watch-outs
Strengths
- RD18AY universal heat pump: up to 10 HSPF2 and a heating operating range down to -22°F (spec sheet); winner of ACHR News' 2025 HVAC All-Star residential product award
- Floating Air Prestige and Classic Plus ductless units listed as ENERGY STAR Cold Climate certified, heating to -13°F (rheem.com)
- Prestige RP19AY carries 10-year parts plus 10-year conditional unit replacement with registration (product page)
- R-454B 'AY' lineup sold in both the US and Canada (rheem.com, rheem.ca)
Watch-outs
- Register within 90 days or fall back to shorter non-registered terms (Rheem Sales Company certificates 92-26150-66-06 and 92-26150-70-03)
- Unit-replacement cover has extra conditions (matched Rheem indoor unit, EcoNet thermostat, district pre-approval)
- Sites still list older 'AZ' models (e.g., RP14AZ, RP16AZ, RD17AZ) beside R-454B 'AY' models; Ruud marks its RD17AZ as R-410A, so confirm the refrigerant on any quote
Which rebates Rheem models fit
Every model in these tables is ENERGY STAR certified, which is the federal equipment rule for the Home Electrification and Appliance Rebates where your state runs them. 58 Rheem outdoor models also meet ENERGY STAR Cold Climate, which several utility programs require. The 25C tax credit ended for heat pumps placed in service after December 31, 2025.
