Preventative maintenence inspection on Carrier propane furnace and Waterfurnace geothermal units. Gas furnace inspection includes filter check, flame sensor cleaning and ignitor test, condensate trap cleaning, operation test to test gas pressure, air temperature rise, and check for carbon monoxide. All gas furnace test came back good with no issues found or suspected. Waterfurnace inspection included operation test to test refrigerant temperatures, air temperature rise, and ground loop pressure/temperature. Only issue found with geothermal operation was low ground loop pressure. Over time, the ground loops pipes with expand and cause pressure drop, and this does not mean there is a leak. Repressurized ground loop from 10psi to 80psi. Low ground loop pressure will lead to inefficient operation due to reduced heat transfer. Inefficient operation causes longer run times. Question about ground loop position should be able to be answered by Jackson Well Services as they were the ins
