Frequently asked questions
Does the Century A-VCD60SA-1 still heat in cold weather?
At 5°F it runs at a COP of 1.91, meaning it delivers 1.91 units of heat for every unit of electricity it uses. Its certified heating output at 5°F is 48,500 BTU per hour. It carries the ENERGY STAR Cold Climate designation.
What does the Century A-VCD60SA-1 cost to run?
About $20.03 per MMBtu of delivered heat at the U.S. average electricity price, roughly 64% less than electric resistance heat. Your local electricity price changes the number — use our operating-cost calculator to run it with your rate.
What refrigerant does the Century A-VCD60SA-1 use?
R-410A, which has a global-warming potential (GWP) of about 2,088. R-410A is being phased down for new equipment, so newer models increasingly ship with lower-GWP R-32 or R-454B.
Where can I buy the Century A-VCD60SA-1?
Century sells this line through HVAC contractors rather than DIY retail, so the way to buy it is to get installed quotes from local pros. Compare the installed price, not just the equipment price.
Sources. Performance ratings from the AHRI Directory (cited by reference number 212940797; not a verbatim mirror) and ENERGY STAR certification data. Operating-cost ($/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.
