Who it's for

Homes in cold climates that want to heat with a heat pump instead of gas or oil.

The standout number

COP 2 at 5°F — it keeps working efficiently when it's frigid.

The catch

Sold through contractors, so the installed price depends on local labor — get a few quotes.

Frequently asked questions

Does the RUSSELL RD18AY24AJVC still heat in cold weather?

At 5°F it runs at a COP of 2, meaning it delivers 2 units of heat for every unit of electricity it uses. Its certified heating output at 5°F is 18,000 BTU per hour. It carries the ENERGY STAR Cold Climate designation.

What does the RUSSELL RD18AY24AJVC cost to run?

About $18.83 per MMBtu of delivered heat at the U.S. average electricity price, roughly 66% less than electric resistance heat. Your local electricity price changes the number — use our operating-cost calculator to run it with your rate.

What refrigerant does the RUSSELL RD18AY24AJVC use?

R-454B, which has a global-warming potential (GWP) of about 466. This is one of the lower-GWP refrigerants replacing R-410A.

Where can I buy the RUSSELL RD18AY24AJVC?

RUSSELL sells this line through HVAC contractors rather than DIY retail, so the way to buy it is to get installed quotes from local pros. Compare the installed price, not just the equipment price.

Sources. Performance ratings from the AHRI Directory (cited by reference number 217176037; not a verbatim mirror) and ENERGY STAR certification data. Operating-cost ($/MMBtu), savings and percentile figures are computed by Verified HVAC Data from published ratings and EIA U.S. average energy prices — see our methodology. Refrigerant GWP is the IPCC value for that refrigerant. We publish no star ratings and take no payment for placement. "Not published" means the source registry doesn't disclose it — we never fill a spec with a guess.
