Frequently asked questions
What does the Panasonic CU-E12RKUA cost to run?
About $20.92 per MMBtu of delivered heat at the U.S. average electricity price, roughly 62% less than electric resistance heat. Your local electricity price changes the number — use our operating-cost calculator to run it with your rate.
What refrigerant does the Panasonic CU-E12RKUA use?
R-410A, which has a global-warming potential (GWP) of about 2,088. R-410A is being phased down for new equipment, so newer models increasingly ship with lower-GWP R-32 or R-454B.
Where can I buy the Panasonic CU-E12RKUA?
Panasonic sells this line through HVAC contractors rather than DIY retail, so the way to buy it is to get installed quotes from local pros. Compare the installed price, not just the equipment price.
Sources. Performance ratings from the AHRI Directory (cited by reference number 7958199; not a verbatim mirror) and ENERGY STAR certification data. Operating-cost ($/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.
