Air-source heat pumps
Rheem Endeavor Line Prestige RP19AY Inverter Heat Pump
Prices are the equipment only — the appliance, before install labour. Where we could only find an installed price, the labour is a national planning estimate backed out to approximate the equipment, so treat those as rough. Get contractor quotes for the install itself.
Rheem's current inverter-driven variable-speed heat pump on the new R-454B refrigerant, and an open 24V system that works with any thermostat.
Our take
The RP19AY is the Endeavor line's answer to the premium inverters, and its two quiet advantages are practical rather than headline: it is already on R-454B, so no phase-down service tax, and it is an open 24V system — any competent tech, any thermostat. The 2.5:1 turndown is shallower than the Bryant's, and HSPF2 is mid-pack, so it is a serviceability-and-refrigerant play, not a peak-spec one.
Best for
Buyers who prize open serviceability and current refrigerant over top specs.
Watch out for
HSPF2 of 8.5 is unremarkable; 2.5:1 turndown is shallower than the best.

Equipment price is not installed price. The listings above are what the hardware costs. Installation — labour, electrical, refrigerant lines, permits, removing the old system — is typically a similar amount again, and varies more between contractors than between brands. Where we have an installed figure it is labelled as such and comes from someone who actually installs.
Compare against
Mitsubishi P-series PUZ-AK48NLHZ Hyper-Heat Ducted System
Mitsubishi's 4-ton ducted Hyper-Heat system on R-454B — the best-documented cold-climate performer in this set, NEEP-listed with a full 5°F dataset.
Carrier Infinity 24 Heat Pump with Greenspeed Intelligence (25VNA4)
Carrier's flagship variable-speed ducted heat pump, and one of very few conventional split systems that holds full heating capacity down to 0°F.
Mitsubishi M-Series SUZ-AK36NLHZ Hyper-Heating
Mitsubishi's ducted Hyper-Heating outdoor unit, pairable with a conventional air handler for whole-house ducted retrofit.
Bosch IDS Ultra Inverter Ducted Split
Variable-speed ducted heat pump that undercuts the premium American brands on price while matching most of their cold-weather capability.
Before you buy this
Ask the contractor for the AHRI certificate number for the specific indoor/outdoor combination being installed — ratings apply to matched pairs, not to the outdoor unit alone. Ask whether they will perform a Manual J load calculation rather than sizing off the equipment being replaced. And check your state and utility incentive programmes: there is no federal tax credit for a 2026 installation, so those programmes are now the only incentive money available, and many require approval before installation.
