On 10/21, I conducted a comprehensive heat pump check-up on a 3-year-old Bosch system. I meticulously examined all electrical connections and voltages, ensuring they were within safe parameters. The air filter was replaced with a size 213, provided by the customer. I inspected the indoor coil and blower motor, measuring amperage draws. Indoor temperature splits were recorded at the supply and return. The outdoor heat pump was tested for BTU output and unit pressures. All outdoor components were inspected, and everything was found to be functioning optimally.

On 10/20/26, I inspected a thermostat that was calling for heat but found no response from the system. After bypassing the boiler at the t&t terminals, it successfully activated. However, bypassing at the thermostat base yielded no results. I traced the wiring and examined all wire nut connections, discovering a broken connection on the white wire. After reconnecting and testing, the boiler resumed proper operation. No charge was applied due to the nature of the installation.

On October 14, I assessed a no-cooling issue with a 2021 Amana communicating hybrid system. Using the Cool Cloud, I connected to the indoor unit and identified a major low line voltage error, causing the system to lock out. This error arises when the incoming line voltage is insufficient for the communicating system to operate. I explained to the customer that no action could be taken until the voltage normalized. After power restoration, I reset the indoor and outdoor unit breakers, tested the system, and checked voltages and 410A refrigerant pressures. During the visit, a power outage occurred, and the backup generator activated, prompting me to inform the customer about potential breaker resets.

On 10/10/26, I assessed a heating issue with a 2025 Trane Link hybrid system. Upon arrival, the thermostat appeared satisfied, but an error code indicated the A2L sensor was not connected to the mitigation board. After verifying the connection, I discovered the blower was running continuously on the gas furnace. Although there is no bypass option for the A2L sensor in the Trane Link setup, switching to emergency heat allowed the system to function normally. I also switched to the propane furnace. The issue began after a recent power blip, and a maintenance visit two days prior. I ordered a new mitigation sensor, which will be returned and installed. The customer currently has heat, and no charge was applied under the 2-year warranty.

On October 6, I conducted a quality assurance inspection on a single head Hisense mini split heat pump system. The customer reported that in cooling mode, with the room temperature at 68 degrees and the set temperature at 77 degrees, the fan continued to run. I contacted Hisense technician support, who confirmed this as the correct operating procedure. The fan operates at medium speed to air sample the room and dry out the indoor coil. This feature is not present in heating mode due to the coil not being wet. I also checked the settings in the power monitoring box and ensured all electrical connections were secure. The mini split heat pump is functioning correctly.

On September 29, I installed new vinyl piping from the heater condensation pump to the sump pump. This involved carefully measuring and cutting the existing vinyl to ensure a precise fit. I then added a coupling to seal the old existing vinyl discharge sewer, ensuring there were no leaks. The condensation pump was successfully connected to the sump pump, which the customer confirmed was operational. I tested the condensation pump to verify it was functioning correctly, ensuring efficient drainage. The entire process was completed with attention to detail, ensuring all connections were secure and leak-free.

Luis 9-23-26 Performed propane gas heat inspection on a newer Bosch heater/heat pump 3 years old. 413 filter ok. Check all electrical connections and components check air delivery system clean combustion components, igniter and sensor inspect burners and offices check low and high stage. Perform combustion test check supply and return air temperature difference ok. Test water safety recycle system OK Bosch system is working properly at a time of service. Heat pump inspection on 1.5 trane HP from 1999. 8 kw electric heat ok test and check all electrical connections and components indoor and outdoor. Customer know unit is old and we have previously informed about issues, capacitors reading below standards, major biological growth inside unit. Outdoor unit compressor is having difficulties compressing refrigerant. Valves working harder to over come friction. Outdoor capacitor is below tolerance. Reversing valve actuator heavily corroded very hard to test or remove wires. Customer know

2.5 Ton Lennox AC piston metering with gas furnace dates to October 2019. *Used Lennox warranty verification to determine warranty expired 2025 System running in a vacuum. Empty of refrigerant. Leak can be heard at indoor coil. *Because system was running in a vacuum for a short period air can be heard sucking into the leak point of coil. Indoor coil needs to be replaced. Very important to consider that because compressor has been running in a vacuum for unknown amount of time, compressor failure is likely soon. Explained everything to homeowner. Sent email estimate to replace indoor coil and install new low pressure switch. Also scheduled sales call for AC replacement for today 2PM. Also emailed estimate for compressor replacement for homeowners information. Left power off to disconnect to prevent compressor from running. Running AC when in a vacuum can cause damage • No obligation quote to replace system • A Comfort Specialist will provide several options to suit your comfor

Luis 8-6-26 Customer called in for radiators getting warm. I check system operation. I noticed there was a call for heat at Boiler, removed stat from wall and still getting call. I check wiring short or old wiring from original installation of house. I replaced 20 feet of wire and installed thermostat back to base ok. System stayed idle and no more call for heat. I talked to customer about todays repair, customer to contact office if they still have issues. No charge warranty.

Luis and Nate 8-3-26 Return visit to check water leak from one of the indoor mini split heads. Bedroom unit. Remove unit from bracket add extra insulation to line set. We also corrected drain line so it drain properly. Test operation ok. Customer also told us to check office unit it seems like was dripping at some point, we also added extra insulation and correct drain pitch. Test drain and system operation ok 19 degree split on all three indoor heads. 56/74 no charge warranty.
