It's fairly common in the US to have central AC plus a gas furnace. Retrofitting the AC with a heat pump lets you move away from the gas system.

- dcuthbertson 3y agoReplacing an AC system with a heat pump might provide you with an avenue to move away from a gas furnace, but I found that avenue to be very expensive. I live in New England and in June 2022 I replaced a broken down AC system with a heat pump. The company installed an electric supplemental heating unit, because the heat pump can work down to only 25F (about -4C) and during Winter it will definitely get colder than that. However, last Winter cost me about $800 more than any previous Winter here (I've lived in the same house in New England for the past 33 years). After a pipe burst in the baseboard heating system (because it wasn't running, it was only -10F outside, and the pipe passed through a poorly insulated area of the house), I had the HVAC company rewire the system to use the gas-fired, forced hot water baseboard system as the backup. I look forward to much lower heating costs this Winter.
- crazygringo 3y agoModern heat pumps are able to work at much colder temperatures than that. I understand your bill went up because the backup electric heating was kicking in. I don't understand why in 2022 it would even be an option to get a heat pump installed that only works down to 25°F. That's super outdated tech.
