Preventative maintenence inspection on 5 total Cooling units. Two geothermal, two ductless mini splits, and one Trane ducted split system. All systems are operating properly in cooling. Geothermal units flushed drain pans, drain traps, and drain pumps. Larger unit by garage steps has a new 30x32x2 air filter installed, supplied by Robin. Other geothermal unit requires two 14x30x1 air filters. Current filters are in decent condition. Test ran each in first and second stage cooling. Performed heat of Rejection worksheet for each unit including both stages. Ductless mini splits air filters cleaned, and test ran in cooling. Outdoor coils are in clean condition. Control batteries (2xAAA each) are not showing low levels and no corrosion. Basketball court Trane system installed new 20x25x4 filter supplied by Westin Air. Outdoor unit is in great condition. No visible rodent damage and coils are in clean condition. All systems are operating properly with no issues suspected or found. All thermo

Upon arrival AC number 1 was locked out on 999 FP1 service codes pertaining to freezing conditions at the txv. During recent house renovations the discharge line water shut off valve at the flow center was inadvertently shut off stopping all water flow through the first floor 5 series water furnace geothermal. After re-establishing the water flow and testing the equipment the ground loops were found to be at 0 psi for the second time in 2 years. Positive confirmation of 55 PSI repressurization on April 16th 2024 is now at 0 psi again at today's visit. Multiple pressure tests at 55 PSI dropped to 40 PSI within 10 to 15 minutes each time during cooling operation of the equipment The low water pressure did not affect the second floor geothermal equipment operation and did not produce any service codes however this equipment is not designed to run at pressure lower than 15 psi and any actions or symptoms of low water pressure cannot be predicted ***The single geothermal ground loop

2023 Trane AC running in great condition. 20x25x1 air filter in good condition. Humidifier damper is closed. Run test unit in cooling mode from thermostat. Delta t of 18F with supply temp of 54F. Refrigerant pressures are within spec. High 340psi with 12F SC, low 130psi with 20F SH. Outdoor coils are in clean condition. Outdoor fan motor and compressor are operating within specs. System is operating properly, efficiently and ready for Summer.

Second floor system: Condensate safety switch was tripped, suspect system froze up during the event in question Reset the wet switch sensor Adjusted airflow, temp drop across the evaporator was too high. It was running a 27⁰ delta, it is now running a 22⁰ delta Suspect either someone bumped the set point too low and forgot to adjust it back or the thermostat got stuck. Got in the attic and traced every inch of the thermostat wire to rule out rodent damage that could have caused a short circuit. No damage to the wiring was found. When adjusting the set point for cooling, we recommend no more than two degrees of change, especially in extreme hot weather and cold weather, as well. Cold outdoor Temps with excessive run time will cause freeze up of the evaporator coil. More than a 2⁰ swing in extreme hot weather will make the system run all day and never get the space down to set point until night time. If the system appears to be stuck on (room temperature is way below set point i
