I had a new closed loop system installed Jan 1 in centeral ohio. System worked great the first week and half than the system would lock off with low water temp. The gound loop system is 5 ton for a 2450 sq ft newer house The ground was really wet when they installed it and is in a low lying area. I get about 12 hrs on than I have to shut it down for 12 hrs to emrg heat. Is this normal for a new system? We had a lot of rain after the install and the ground has settled. Any help would be great.
