Geothermal vs Carrier Greenspeed
I am looking to replace my current Heatpump. I have a dual zone heat pump with a Rheem for the top floor that is 14 years old and a Trane for the main level that is 10 years old. The Rheem is 12 SEER and the Trane is listed at 14 seer. My electric bills in the winter are very high so was looking to save money by switching to more efficient system. My house is 3400 sq ft. The rheem is 3 ton and the trane is 2.5 ton. I live i Southeastern PA.
I had a contractor out to get an estimate on switching to geothermal. He was suggesting a vertical closed loop system. In the process of discussing options he mentioned the Carrier Greenspeed as a cheaper option. He stated the energy efficiency was close to geothermal.
I am still waiting on the quotes but was interested in what others felt about geothermal vs greenspeed. I would like a ROI within 10 years. My other question is whether I should get an energy audit and if yes how do you find someone to do them?
