Had Jim drop off four bags of salt for water softener.Collected payment for salt, condensate treatment and filter.

Performed tune up on Bosch heat pump, customer stated fan make a pulsing sound on start up so I tested the fan thoroughly and found no electrical issues with motor. Fan does make a rattling sound that comes and goes every 10-20 seconds then subsides completely after about 2 minutes of run time. Spoke with Joe about issues and he said to take a video and add it to the call and order a new fan motor and wheel and replace both .other than that system has zero issues in either heating or cooling mode. Spoke with customer about a surge protector and he agreed to install one when we come back for fan motor replacement.

Set new furnace in place set existing coil on top of furnace and built transition. Installed new 10x25 Return drop. Adapted to gas piping and checked for leaks. Made all high and low voltage connections to unit. Wired all safeties in series to break 24v R call to thermostat thermostat. Ran new condensate drain to existing condensate pump and checked for proper drainage. Drilled new holes for new pvc flue pipe and ran pipes to new furnace. Performed all test out procedures cleaned all work areas and reviewed installation with homeowner.

Customer had unit diagnosed by another company as bad compressor. Reviewed equipment , commercial equipment, r22 refrigerant. Need to determine compressor availability or outdoor replacement options.

Estimate

No heat from the furnace thermostat set for heat, but no heat coming out of the vents went downstairs noticed the burners are lighting. After a few minutes. System goes into a high limit lockout. Inspect blower balance motor 10 MSD capacitor rating 9.7 MFD. new blower is needed. Inspected heat exchanger for any damage found split on the middle of the heat exchanger. Red tag heater and told customer that most likely he will need a new furnace call carrier to verify parts of availability. Heat exchanger is back order between month and a half to two months. Repair cost is the same as replacement of unit. Home comfort consultant to reach out to customer.

In order to access the Blower Compartment of the ceiling unit in the Employee Breakroom we will need to disconnect and remove a section of the ductwork in the ceiling. After the ductwork has been removed and the blower motor compartment can be accessed we will further troubleshoot the system. *This proposal is for the removal of the ductwork and troubleshooting the system. Any repairs that will be needed will be provided in an additional estimate. Two technicians required due to being located in the ceiling. 2-27-25 Luis and Aaron return visit to troubleshoot unit, we were able to locate blower compartment from right side without removing any ductwork. Found blower motor shaft seized. With major play on shaft. New blower motor is needed called manufacture I was able to find motor from supplier. Would recommend getting an estimate to replace system since a lot of parts are been obsolete from taking to manufacture. Provided estimate to replace motor. I will talk to supervisor about s

Arrived at call for issue with condensation pump. Checked pump which was off, filled pump with water and once water was drained it continued to run, disassembled pump and found it was very clean almost brand new still, float mechanism was sticking due to a defective pump. Installed and re wired pump and tested with a gallon of water. No charge to customer due to new install.

Found electrodes worn down on Weil McLain boiler, Replaced electrodes. Also perform precision oil tuneup on one oil, furnace, and one oil boiler. Vacuumed all set from smoke pipe and heat exchangers and vacuumed chimney base. Replaced point 60 x 80 B nozzle and 1.25 x 80 B nozzle. Performed smoke test. Replaced our F1 oil filters.

Add refrigerant to system this includes up to 3 lbs of 410 with injection of dye. Any additional refrigerant 93 dollars per lb. 2/18/25 Luis and Nate return visit to add refrigerant and die to the system. Total of 6 pounds were added 410a refrigerant also dye were added on todays visit. We will check for leaks during ac tune up ( some time in April).

Estimate

Employee Breakroom Unit making grinding noise. Found system off upon arrival reset disconnect and note as noise was coming from the blower motor. Try to get to the blower motor, but was not successful. Told Bill that I cannot do anything. Most likely the issue is blower motor and wheel. Most likely the entire unit needs to come down from ceiling.

Fully assessed no heating situation. Found nothing running. Check for 240 V at air handler and did not have it. Found 100 amp breaker tripped to air handler. Reset breaker and tested operation. Strip heater was drawing 61 A. Heat pump alone was doing a 25° temperature rise. Did not see any burnt wires or anything to be concerned about. Explained to homeowner that if breaker would trip again would consider replacement of 100 amp circuit breaker. Heat pump is working fine again at time of service.

Fully assessed no heating situation. Found furnace running when I arrived but thermostat was 10 degrees off from set point. Homeowner is doing construction on the home and the air filter was caked with dust. Homeowner then replaced aprilaire 413 that he had. Found furnace lighting but then shutting off even after replacing the air filter. Found flame sensor was pitted and in rough shape. Recommend replacement of flame sensor. Furnace is 10 years old and is getting older. Installed new flame sensor and tested operation. Checked temperature rise. Performed combustion test. Gas furnace is working properly at time of service.

Performed tune up on Bosch heat pump, tested unit in emergency heat mode. Checked heat strips, blower motor, and all electrical components in the indoor unit. Went to outdoor unit and checked refrigerant levels, and all mechanical components in the outdoor unit. Went to older rheem system and checked units heat strips, blower motor, and indoor electrical connection. Went to outdoor and tested refrigerant levels, outdoor fan and compressor and all electrical components. Noise customer was hearing is due to unit being mounted on a wood platform connected to the house and it is shaking . If I lift up on the platform slightly the shaking stops. Noise was only noticed Wednesday and is no longer an issue and a significant amount of ice was built up on pad but has melted since then, entire pad would have to be removed and rebuilt and outdoor unit would have to be reinstalled. Told customer to wait until unit gets replaced.

Installed ecm surge protector for lobby unit and re piped entire condensate drain and wired in safety. Systems were tested after repairs.

Performed a QA on a heat pump system. Took photos of the equipment and looked at the overall install of the indoor unit and the outdoor heat pump. Looked at the wiring connections and the voltages.
