Customer recently replaced the air filter. Coils and blower wheel are clean. I checked the electrical wiring and electrical systems, including the 15KW auxiliary heat strips, all are within specification. I operated the unit on heating mode and recorded 25 degree temperature rise and 105/315 pressures, iat 65, oat 40-45. I forced the defrost cycle and it indicated and completed its cycle. Unit operating normal.

Air filters were replaced mid September and mid October by the customer. Air coils are clean. I pressurized the 2 ground loops to 65psi. I checked the electrical wiring and electrical systems, including the auxiliary heat strips and their safety devices, all are within specification. I operated the units on second stage heating mode and recorded 25-30 degrees temperature rise across the air coils except for unit #3, which was >30. I increased the blower speed to drop the temp rise to under 30. I calculated heat of extraction and they are all extracting slightly more heat from the loop than the printed data, which is great. Units are all operating normal. There is no surge protector on any of the equipment. Installing one on the main entrance panel will protect everything served by that panel. Also unit #3 in the attic may benefit from a Blue Tube ultra violet light and Ez Trap drain line assembly with built in overflow protector.

Water heater was found giving low water pressure to all sinks. I opened two sinks pressure would dro to almost nothing. I connected my gauge to both water heaters and found the first water heater old for one problem and two the amount of built up setiment in the water heater was really bad. It’s clogging the unit from being able to satisfy the proper amount of pressure to the system. I would recommend draining both water heaters down replace the one old water heater. Change off old gate valves while water heaters are drained down. Install new ball valves and test proper pressure for system. Will need to start here first. Since were also here and already have the lines drained down customer wants to swap cop pro before check valve.

Upon arrival I was told that main house attic system wasn’t cooling. Customer suspecting plumbing service because some breakers were shut off during service. During diagnostics I found system getting correct signal from thermostat, high voltage present, pumps running, but system locked out on high pressure. Reset power to AHU and cleared fault, system started cooling. Checked heat rejection and pump amp draw. Measured delta air temp and system is operating normally. This unit doesn’t send voltage to pumps directly, uses slaved control to send signal to another system for pump control. Because breaker was off for the other system, this one faulted. Fault needed to be cleared by cycling power to attic system before running ac again. Unit is operating normal at this time. Called customer to let him know what I found because he wasn’t home. Customer explained that plumbing service done previously on fitting is still leaking and would like it addressed. I told him I would send info to

I replaced the air filter in the geo unit which the customer had on hand. I cleaned the condensate pans and drain lines on both units and ran hot water to flush the debris out and to check for proper drainage. Both units cooling with 20+ degrees across the evaporator coils. The flow rate and heat of rejection for the geo unit is proper. I checked the electrical wiring and electrical systems, all were within specification except for the od fan motor side of the dual run capacitor for the Carrier heat pump. I replaced the dual run capacitor and retained the failed part to return to Carrier. I also installed a whole house surge protector on panel #1. Upon inspection, panel #2 had a whole house surge protector alteady installed. Both panels now are protected and both units are operating normal.

Upon arrival I was told that geo unit in addition wasn’t heating. Found unit locked out on water flow. Put gauges on system and ran heat, found system is low in 410a. When removing suction side cap I found schrader pin is where leak is located. Repaired pin and checked for other leaks, none found. Spoke to customer and he approved repair. Added 410a to system and balanced Superheat and subcool. Measured delta air temps and delta loop pressures and temps. Unit operating normal. Customer also asked me to replace filters for console unit. Found filters in back storage of main garage but customer didn’t have both sizes of filter. Could only replace filter in laundry room garage console unit.

Customer had questions about why the thermostat wire could not be pulled through. I explained I tried but it snags on an obstacle under the floor. Removing flooring and patching plaster walls would cost more than to install a radio frequency thermostat with equipment interface module. Customer also said they only paid for 2 10KW backup heat packs and questioned about how I knew there was one in the split system air handler. I explained the process of testing the equipment and trying to run it from the existing thermostat and it would not turn on. The two elements are visible when the cover is off of the air handler. Even when I tried to run it from the terminal strip in the air handler it would not come on until two high voltage wires were switched between l1 and l2. Maybe I uncovered a problem they did not know they had. My job was too test the equipment in heating mode. I found a problem, tried to resolve it the cheapest way, but when that didn’t work offered the best solution t

I reset the thermostats to default heat stage setting of .5,.5,.5. Both ground loops haves cold temperatures and are not heating as well as could be because they have been running constantly. Unit #1 and #2 are operating normal. Unit #3 has back up heat staging but does not work because they ran a 5 wire thermostat wire from the air handler to the thermostat. There is not enough wires to make it work. I quoted a repair to fish 8 wire through but it hit something in the wall and I had to stop and connect it back the way it was. I showed the customer and recommended Honeywell wireless thermostat with equipment interface. I will send a quote and customer will speak with there partner about it. I checked the electrical wiring and electrical systems, all are within specification. Flow rates are set correctly. Loop pressures are adequate.
