Heatpump or gas
Sorry to those of you following all of my other threads regarding the unit. I felt like I needed to start another thread to generate some feedback since my original thread was started as a question of unit size.
Anyway, below is the proposed systems.
We're in central SC. The roof deck is foamed and the walls were upgraded to R-15 and garage ceiling to R-30. We asked for gas heat downstairs but now I'm questioning the decision. Our manual J calculation requires btu of less than 34,000. The proposed has a capacity of 40,000-120,000. He says it's the smallest variable speed available. Going to the non-variable speed takes us down to a 13.2 seer.
2.5 ton split heat pump UPSTAIRS
14 seer (ARI# 3701069)
HEAT KIT: 9 KW
Any thoughts on gas vs heat pump or advice on the particular system that has been proposed?
