Need a little help.
Just had a geothermal system installed. It s split 5 ton system(2/3). I am in Kentucky and there are 5 150ft deep holes.
Problem is the system doesn't seem to be running efficiently so I was curious and felt the temperature of the water lines. The outlet line is hot, i would guess 120 degrees. The return line is about 30 degrees cooler but still very warm to the touch. The installer tells me this will all balance out in time. Its been running for about a week now. The upstairs system cant hold 70 degrees during the day.
This system replaces a heat pump system that worked fine for 10 years.
I am afraid the holes were not backfilled and htere is air around the lines. Am i way off base?
Could it be something else?
Appreciate any help.
