1. I need to replace 20yr old existing heat pump. It's compressor is broken and service guy told me, it's needed to replace. I am getting different quotes, but I am not sure of which model. I know carrier/trane are on expensive side. I got quote for gibson model. Are they good?
2. Gibson model is basically A/C condenser (not heat pump). Contractor is suggesting me to use heat-strips only in winter and condenser in summer.
I am not sure, whether i should agree with that? He said, it's going to be same efficient. I am confused. I read, heat pumps are more efficient.
I am in NJ, winter temp goes down to 10degrees..avg.
