On our property we have a main house and a guest house. The guest house is two stories with my woodworking shop on the first floor and a one bedroom, garage apartment on the second floor that I use for my office since I work from home. The HVAC system has a gas furnace that still works but the air conditioner just can't keep up any longer. The system is 27 years old so I would say I got my money's worth out of it!
I've had a couple different HVAC companies quote a replacement and the guy that came out yesterday quoted a standard gas furnace but also quoted an option for a dual fuel system. This type of system uses a heat pump for primary heating but will switch over to the gas furnace when the temp drops below the threshold where the heat pump becomes inefficient. I'm considering this option because it would require much less propane (wouldn't have to fill the tank as often) and I would think heating primarily with electricity and occasionally with gas would be cheaper than heating 100% with gas.
The average winter temperature in this area is 38-58 degrees but it can drop down in the 20's and teens sometimes. Anyone here have experience with this type of system and if so, what are your thoughts?
TIA!
