Found E5 error code at second floor Furnace. Blown 3A low voltage fuse. Checked for shorts with ohmmeter. No shorts found. Also inspected low voltage wiring for any exposed wires, loose plugs or connections, etc. installed new 3A fuse. It did not open/pop during my time here today, Tested system. Temperature split 21° Good BOTH 20x25x5 filters should be replaced ASAP. I showed her how to source them online and how to change. Discussed plan memberships for both systems Both systems heat pump /propane furnace hybrids. Furnace is Daikin dating to 2019, Heat pump is Lennox dating to 2014. Client paid for (2) plans and diagnostic fee today.

Estimate

Installed new trane tahm air handler and heat pump outdoor. Placed indoor unit in condensate pan with float switch Adapted return and supply ductwork. Tapped/caulked return and supply. Ran new condensate line with ez trap and condensate pump. Adapted vinyl tubing. Adapted high volt and installed new heat kit. Installed new trane thermostat and wired in low volt with safeties. Flushed line set and connected to new equipment. Installed new trane thermostat heat pump on leveled pad with snow legs. Installed new recto seal disconnect and wired into outdoor unit. Cleaned up work area and tested out equipment. Was not able to start up unit. We were receiving a Trane communication error. Called Nathan to verify. He will return tomorrow. Units needs to be tested out. Added 1lb of r454b. 7/9/25 The issue with the error code 114.12 was caused by system controller not having most up to date software version. Installed new S360 controller then started system. Verified R454B refrigerant charge. A

Found 3 Ton R410A heat pump with failed indoor blower motor. It is a variable speed blower motor. Contacted Ferguson for prove and availability Found compressor not starting Turbo capacitor wired for 45/5 Good Outdoor unit Needs hard start kit and contactor. Condensate pump in attic needs to be inside a pan with its own water safety shut off. This is included in the estimate labeled Mandatory repairs. *System is well beyond the lifespan for heat pump system. Dates to 2006 would not recommend spend any money on repairs. I’m nice we get system running there may be additional issues IE refrigerant undercharge. System is down until repairs are made. Gary decided he wants a consultation for system upgrade. Consultation set up for 12-1PM today.

Customer called in for no cooling, blank thermostat found no power to unit reset power and checked wiring found faulty switch at unit. Bypassed switch and test operation noticed system is from 2007 and uses r22. Indoor oil heater has open return, would recommend getting and estimate to upgrade system to prevent any breakdown and peace of mind that is not going to break. Office to contact customer for home comfort consultant to come out,

Performed tuneup on carrier AC, checked indoor units drain, blower motor, and temperature split and coil. Went to outdoor unit and checked all electrical and mechanical components, including capacitor, fan motor, and compressor. Tested refrigerant levels, no issues with the unit this time.

Arrived at call for comfort issue, went to boiler and checked all settings, parameters, and reading kn boiler. Noticed the outdoor temperature was off by about 5 degrees from the actual temperature. There is a setting on the boiler to adjust temperature plus or minus 5 degrees so I set it to read 5 degrees below and the boiler immediately ramped up to satisfy, performed combustion analysis and checked over entire system to ensure no other issues were present. Told customer to monitor system overnight and if it still didn't satisfy we would have to replace sensor. House is very old and had one foot thick stone walls, older system in house had cast iron radiators but now has slant fin bas boards when it was renovated.

Perform precision heat tuneup on carrier heat pump system. How many are just replaced 16 x 20 x 1“ air filter. Checked all electrical connections and components. Check temperature rise. Tested emergency heat. Found no surge protection on X 13 blower motor, provided estimate. Tested outdoor capacitor. Checked refrigerant pressures at indoor and outdoor units. Heat pump. System is working fine at time of service.
