On 9/30/26, I thoroughly assessed a cooling issue with a 2022 Bosch heat pump system. Upon initiating a cooling call, the outdoor unit activated, but the blower motor did not. The ECM blower motor rocked back and forth a few times before the system shut off. After checking for 240V and 24V power to the motor, it was determined that the ECM blower motor had failed. I explained to the homeowner that additional failures could not be ruled out due to a possible power surge. I provided an estimate for a warranty blower motor replacement and a heavy-duty surge protector. The homeowner opted for the repair only. I sourced a new motor, installed it, and tested the system. The temperature split was 20 degrees, and R410a pressures were 304/130, confirming proper operation.

On 9/30/26, I conducted a comprehensive heat pump check-up on a six-year-old system. I began by examining all electrical connections and voltages to ensure proper functionality. The air filter was checked and found to be in good condition, with the correct size being 401, and the humidifier was serviced with an #35 filter. I inspected the indoor coil and blower motor, measuring amperage draws to confirm efficiency. Indoor temperature splits were taken at the supply and return points. The outdoor heat pump was tested for BTU output and inspected for any issues. Unit pressures were also checked, and everything was found to be operating correctly. The service was completed, and payment of $189.00 for the service agreement renewal was collected via credit card.

50 gallon electric water heater Rheem has water in pan. Locked out on built-in water alarm. The water in the pan is NOT coming from the relief valve. The relief valve piping is dry as is the the part of the pan directly under neath it. There is a small tank leak. New water heater is needed. I dried the water sensing rope and left outside pan for temporary hot water. If leak gets worse you must close the valve and turn water heater off. The expansion tank is failed (water logged) needs to be replaced as well Water pressure 58/psi: Ok I used Rheem warranty verification and there is a tank warranty until Feb 14 2031. However this is through Home Depot who typically wants the company whose phone number is listed on the water heater. Our staff will contact Rheem then the homeowner tomorrow to see if we can do the water heater replacement under warranty. Also provided estimate for new electric water heater with leak sense and 8 year tank warranty AND estimate for professional electric

8/19/26 Dan 2nd floor system wasn’t working do to the condensation pump being full of water it tripped the safety. Found ez trap and drain line is clogged. I cleared the lines and tested multiple times . The a/c is back on and running. The customer did sign up for a single contract for the 2nd floor amana system . Everything is draining and working properly at this time. I collected for $516.25 for today’s service, paid by cc. Please schedule the customer for his 1st cleaning in the fall 2026

Philadelphia met with homeowner Mike. They are good friends. Quoted heat pump and coil options as well as complete system options. Customer is in the mindset of when he has to replace it when it finally fails. He’ll probably start with just the heat pump coil for money reasons will also need financing. He will call Bill if and when it dies to get the ball rolling to replace.

8/13/26. Fully assessed no cooling situation on 2017 Rudd heat pump system. Went downstairs when I arrived and gave system a call for cooling situation. Found water all over the floor around furnace. Homeowner recently replaced his own circuit board. Checked over wiring and dip switch settings. Went outside and checked r410a refrigerant pressures they were 301/95 with 20 subcooling and 32 superheat with a 29 degree evaporator coil, this is freezing pressures. Removed sensing bulb from suction line pipping and gave system a call for cooling again. Suction pressure did not improve. Txv is un responsive. Provided estimate to replace indoor txv but highly recommended replacement of system. He is going to decide next steps.

I Took indoor temp splits at the return and the supply and checked the blower motor condition and operation. I looked at the outdoor unit wiring connections and voltages . I inspected the outdoor components and checked my unit pressures by using super heat sub cool method. The system is currently operational but past normal life expectancy. Replacement of system is recommended in the near future. I did leave the customer a few estimate options for water safeties and the correct air filter . The customers will review these options with their son .

Luis 7-20-26 Performed ac tune up on two heat pumps. Second fooor and basement. Change both filters. Flush drain test pumps ok. Check airflows supply and return ok. Inspect coils and blower. Check outdoor unit refrigerant pressures and levels ok. First floor unit under manufacture specifications. Second floor unit uses r22 refrigerant. System currently operational but at end of normal life expectancy. Due to age and likelihood of issues moving forward, replacement of system is recommended. Customer will continue to run system until units needs to be charge with refrigerant again.

I arrived for a 50 gallon electric hot water heater not working not producing hot water. I found I found the breaker was tripped. I checked my water pressure checked both elements and thermostats. My top element was OK. The bottom element was failed. I gave the customer a few options. I gave her the option to replace the element and I gave her an option for a water heater replacement talking with the customer. She decided on going with a new water heater, she is scheduled for Monday. We did take an extra three hours off the water heater purchase, for the meantime, the bottom element and capped off so she will least have a little bit of warm water for the weekend. Please collect full payment for the water heater when completed I collected for my diagnostic fees for looking over the water heater and capping off the bottom element .

Luis 7-15-26 • Replace combustion blower and air venturi Test system operation ok. During today’s repair I noticed one of the screws on manifold is stripped (going into Venturi) next time we work on gas side we will need all four new screws.

Luis 7-14-26 Customer called in for no cooling. found thermostat in the off position Upon arrival. test system operation from thermostat set to cooling lower than room temperature, outdoor heat pump came on but no operation from blower. After troubleshooting found control board not energizing the motor. Test fan motor speeds by hot wired motor. Fan motor works. I provided estimate to replace board. Customer has had issues with current unit I mentioned to customer about system replacement, customer does not want to explore system replacement option at this time. Emailed estimate for repair and recommendations. Customer has cooling since motor is wired to run all the time. Customer will call office when ready to move forward with repairs.

Removed screws that were blocking the filter from sliding in. Put new filter in. customer says we caused nail pops to her ceiling drywall from us walking in the attic and putting in insulation.

Estimate

Installed (2) X13 blower motor surge protectors and (2) wet switches. 1 wet switch and 1 surge protector at unit #1 1 wet switch and 1 surge protector at unit#2. Tested wet switch on each system. Wet switches and float switches are wired in series to break power to the thermostat altogether. Both system operating well at this time. I caused a piece of plaster and a small part of the paper face of the drywall top pop on both sides of the wall when I was working. I informed Joe. The company is going to get a drywall contractor and they will give us the bill.
