My house has a geothermal system that has been working great so far this summer but the past couple days it has not been cooling I am going to have a tech come look at it tomorrow but was wondering if anyone could help. I had a friend come check it out but he doesn’t know much about geothermal as he just works on traditional systems.
Symptoms:
- high head pressure
- sounds like system is possibly sucking air but could be normal we are unsure(will attach video)
-cools at random times but does reach thermostats set temperature
Please respond with any help or if additional information is needed. (It is a closed loop system about 10 years old with 300lf of pipe for the loop)
