Hairer heat pumps: 4 ton or 5 ton?
I'm doing a program in my area to upgrade from oil to a heat pump. I have a 2300 square foot house attached at one side to another property and have 9-ft ceilings ( about 8 ft or 7.5 ft in the upstairs )built in 1928. Would I need a four or five ton heat pump?
Also : I was quoted for a 3- ton haire heat pump and I don't know if that would have been appropriate and I don't know what the Brand's reputation is. Any inputs on this?
