Tetco Geothermal Model HECWE-50 (30Yrs)
I have a 30 year old geothermal HP thats needs a replacement compressor. It's a Bristol H21A413ABCA unit. Copeland makes a replacement unit that prices go from around $600 to $1000. I had the heat exchanger unit replaced in 2006 for $1200. I use 2 wells for drawing water from and returning water to the ground. My question is should I put anymore moneys into this unit (30 years old). A geothermal service tech that determined that the compressor was bad, suggested that it would be cheeper to remove the GeoHP and replace it with an air-to-air HP. Living in North West Pa. the winters are pretty cold and I don't know if an air-air unit would work that well compared to my current GeoHP.
Any advice would be appreciated.
