I'm going to most likely be really bad at wording at this but this is my last effort to try and get some information and help before having to find someone and pay them to come fix the problem. Me and my dad in 2008 started to DIY install on both the Geothermal Units we have and did everything, but I never learned the maintenance and troubleshooting of either of the Geothermal Units and have no knowledge of HVAC at all. I would normally call him and ask questions if things stopped working but this past July he passed away from cancer. For our downstairs unit we have a "Hydro-Temp Earth Coupled Heat Pump" can get serial number if needed. For our upstairs unit we have a "ClimateMaster Water Source Heat Pump" can get serial number if needed. Both units have a HoneyWell filter system to the upstairs and downstairs. We do not have a well or a pond, as far as I know the system is running from our pool and the lines for the units are buried beside our pool and in our front lawn. The problem with both of them I am having is the upstairs and downstairs units have stopped cooling and will only blow out air such as if you have a fan right next to you blowing on you. I did my best to lookup all the information I could and learn myself to find the problem but just can't. Right now our pool is very very very dirty right now and didn't know if that could lead to the problems i'm having for the units not cooling and the only thing I have done to try to get them running again is cleaning the filters from the HoneyWell's and replacing both units with new run capacitors. I'm really just at a dead end and can provide more information if needed even pictures.
