McKinney, TX – AC Repair & Heating Service

I arrived to our clients home for unit not cooling properly. Derek stated that the unit was struggling to cool the home and reach desired set point. He also mentioned a water spot in the ceiling that had previously been addressed. I first proceeded into the attic and verified that the drain pan and primary drain line were clean and clear of any moisture. I did however find a wet spot in the attic insulation behind the unit about 4 feet and directly below the attic bird cage vent. I then proceeded outside and found the heat pump to be in a full lockout. This was restricting the unit o come on at all as a safety. I reset the compressor but I tested the electrical components and found the capacitors to be failing. They are extremely below manufacture specifications. I also found the coils to the outdoor unit to be dirty and full of dust. The indoor blower motor also has dust accumulated on it and the motor is exceeding the max amps from the manufacturer. I showed all my finding to our

Performed single system cooling maintenance. I checked amps, capacitor, filter, electrical, drains, cleanliness, and safeties. The system is performing inside of manufacture specifications. I recommended that a chemical cleaning be done on the outdoor unit, a drain treatment be performed, addition float switch for added protection, and more insulation be installed. I provided pricing for recommended safeties/repairs. Performed drain treatment during time of service. Total-C is a water soluble formulation, containing ingredients that produce a pleasant, fresh citrus scent and sludge eating bacteria, which eliminates the source of the odors and keeps your drains smelling fresh. A small amount goes a long way toward maintaining an odor free atmosphere that you and your family will appreciate!

Performed single system cooling maintenance. I checked amps, capacitor, filter, electrical, cleanliness, drains, and safeties. System is performing mostly within manufacture specifications. I spoke with the home owner about the possible need of duct cleaning in the coming years. Also, we had a discussion about the hard start kit and what happens if the compressor over amps on start up for too long. The customer spoke about some allergy issues that his wife has and I provided options for u/v lights. I am concerned that the ApcoX will not even fit due to du t placement. Customer would like to speak with his spouse about the offered services.

Arrived at home for humidifier not working properly in the master bedroom area. I insured that the thermostat was set properly with humidifier settings and set points. I proceeded upstairs and found the float switch to be wet as if previously engaged. I ensured the low-voltage wires were connected and sending the correct signal. I was able to bypass the water safety switch and insured that the unit was receiving power. I Found the control board to be burnt and not sending the correct signal to initiate the steam humidifier. We will need to replace the board before further testing. I also spoke with our client of how multiple safety interruptions to the board could actually cause this issue to happen and burn the board. I am also including a blow out valve and drain clearing to help prevent this problem from happening again. The upstairs unit did not have the humidifier programmed and once we established the correct program on the thermostat we tested it t9 ensure it was working proper

Talked to customer about maintenance agreement renewal, power surge, she agreed to send her estimates for recommendations.

Performed single system cooling maintenance. I checked amps, capacitor, refrigerant, cleanliness, electrical connections, and electrical components. The system is cooling to manufacture specifications with some recommendations. Recommendations 1. The outdoor unit has some build up that requires chemicals to assist in removal. A dirty condenser coil causes the system to not cool properly because the system can not efficiently expel the heat. 2. The drain needs to be prepared for cooling season. A drain treatment is recommended to ensure a nice clean drain.

Relocation of steam humidifier closer to plenum box includes - extending electrical wire - securing humidifier to new brace - adjusting hose length to new supply plenum Finished installing zone control board and remainder thermostats. Also our Client elected not to have thermostat back plates installed with corresponding thermostats. Also today we went system by system and took all measurements from supply vents before and after making airflow adjustments to our client satisfaction. He is aware that included with today’s visit is one courtesy follow up visit to make any additional adjustments. We did also discuss adding additional return air for certain rooms/areas in the home to help with overall comfort. Our client is happy with completed work and will run his units for about 4 to 6 weeks to accurately assess adjustments made today.

Diagnostic Report Issue: • Compressor making noise on the heat pump outdoor unit. Action Taken: 1. Contacted Trane Tech Support: • Advised to reduce the RPMs on the heating side of the heat pump outdoor unit. 2. Adjustments Made: • Adjusted the controller outside to lower the RPMs to a medium setting. 3. Inspection and Findings: • During the check-up, Braden found the air filter was dirty. • Offered to clean the filter, but the customer opted to have her husband do it. • Tech support mentioned that a dirty filter could contribute to the compressor noise due to airflow restrictions. • Observed significant oxidation buildup on the condenser. The condenser requires a chemical washing to remove the oxidation and improve efficiency. 4. System Testing and Results: • Program adjustments were made to slow down the RPMs on the heat pump side. • Test ran the system in heat pump mode to confirm the noise reduction. • Confirmed that the system was functioning well with the new sett
