Kyle TX Heating & Air Conditioning Services

Installed 1.5 ton Carrier R-454B ductless system. Indoor unit mounted to the wall in the garage. Outdoor unit is mounted to the brick wall outside with mounting bracket. Made new flares connections for the refrigerant lines and pressure tested them with nitrogen. Checked for leaks with bubbles and pulled vacuum. Installed line hide to cover the lineset and condensation drain line. Installed new 20 amp breaker and ran new wiring to supply power to the system. Tested operation of system. Everything is working at completion of install.

Performed a/c tune-up on a Carrier straight cool system. Checked the electrical, mechanical and performance systems of the unit. Cleared, cleaned, flushed and treated the drain line and replaced the return air filter. Secured outdoor compressor wiring and washed the outdoor coil. Did find the indoor coil is starting to develop some rust spots and can be prone to a refrigerant leak in the future. No other issues were found. The system is operational at this time.

Performed a semi-annual maintenance inspection on both HVAC systems. Inspected all high- and low-voltage electrical wiring and connections and tightened the low-voltage connections as needed. Flushed and cleared both condensate drain lines and verified proper drainage. Inspected both blower assemblies and found no signs of buildup or biological growth. Evaporator coils were inspected and found to be clean and free of buildup. Washed both outdoor condensing units from the inside out and inspected all electrical components. Both soft-start systems were tested and confirmed to be operating properly. Run capacitors were tested and found to be within manufacturer specifications. Checked the refrigerant pressures on both systems and found them to be within the appropriate operating range. Both systems were tested and confirmed to be operating properly and cooling as expected at the completion of the maintenance.

Sealed all of the supply buckets and return boxes to the Sheetrock with mastic. Sealed the ductwork connections at the plenums with mastic. Cleaned the exterior of the furnace and evaporator coil. Cleared out the primary condensation drain and primed with water. System is operating and everything is working at completion of service.

Installed Carrier 4 ton furnace and condenser. Installed new plywood overlay. Installed new filter base. Installed a new supply plenum. Sealed all connections. Rebuilt drain and installed SS2. Cleared drain and primed trap. Replaced gas flex. Replaced flu pipe in closet. Installed new condenser pad and new disconnect. Pressure tested lineset and pulled a vacuum. Installed Ecobee thermostat. Tested system operation and charged system to meet manufacturer specifications. Everything is working at completion of install.

Performed AC cooling check. Checked the electrical, mechanical, safety, and performance of the system. I cleared the condensation drain line and flow tested the drain with water. I also treated the drain line. The air filters were new and had been recently replaced by the homeowner. I cleaned the condenser coil. No major issues were found. The system was running at the completion of service.

Service diagnostic found the blower motor had failed. This caused the indoor coil to freeze over. The secondary drain pan is slightly undersized and was not catching all the water from when the frozen coil thawed out. Also found the outdoor capacitor is starting to fail but is still operational. Spoke with the homeowner and he chose to have the blower motor replaced. I replaced the blower motor. Secured all furnace wiring terminals. Function tested the system and turned off the fresh air system to help decrease humidity levels in the home. Did find the system airflow was not matched to the outdoor system tonnage. This was causing the system to run with very high static pressure which most likely caused the motor to fail. I lowered the fan fan speed to deliver around 1100CFM for the 3-ton system. Informed the homeowner the system static pressure is still high at .85 in.w.c. Due to the location of the system there is no room for ductwork improvements. Also secured the compressor

Pumped down existing refrigerant to the condenser. Installed new TXV metering device and liquid line filter drier in the attic at the evaporator coil. Insulated the new sensing bulb. Pressure tested system with nitrogen and pulled vacuum. Cleared primary condensation drain and primed trap with water. Checked the factory condenser capacitor reading 42/45 and 4.6/5 it is still within spec. Charged AC with R-410A refrigerant. Tested operation of system. Everything is working at completion of service.

Diagnostics found the outdoor torque booster had failed, preventing the outdoor unit from coming on. I went over my findings and repair options with the homeowner and they chose to have the torque booster replaced today. After replacing the outdoor torque booster, I function tested the system. The system is cooling at time of departure.

Performed a/c tune-up on two heat pump systems. Checked the electrical, mechanical and performance systems of the units. Cleared, cleaned, flushed and treated the drain lines. Replaced both air filters and washed the outdoor coils. Did ask the homeowner to keep an eye on the upstairs system since the indoor coil is rusted out and prone to a refrigerant leak in the future. No other issues were found. Both systems are operational at this time.

Diagnostics found the condenser fan motor for the downstairs unit had seized up. I went over my findings and repair options with the homeowners. They chose to replace the condenser fan motor today. I replaced the condenser fan motor then cycled the system on to verify proper operation. The system was cooling at completion of service.

Service diagnostic found the outdoor fan motor had leaked out all the lubricant which was causing the motor to seize up and fail. Every time the fan motor shut down it caused the compressor to overheat and shut off as well. I spoke with the homeowner and he chose to have the outdoor fan motor replaced. I replaced the outdoor fan motor, programmed the motor to the correct speed, and rinsed out the outdoor coil. Did inform the homeowner the dryer vent is next to the condenser coil which is causing the coil to accumulate more dirt than usual. I also cleared out the primary drain at no additional charge to the customer. No other issues were found. The system is operational at this time.

Service diagnostic found the drain line was clogged which was tripping the water safety switch and causing the system to shut off. I also found the outdoor capacitor below manufacturer rated value. The outdoor starter relay is also pitted. Spoke to the homeowner and he chose to have the outdoor capacitor replaced. I replaced the capacitor and secured the outdoor wiring terminals. Cleared and treated the primary drain line and rinsed out the outdoor system at no additional charge to the homeowner. Did also recommend replacing the air filter with the correct size to prevent any filter bypass. Function tested the system and everything is now operational.

Service diagnostic found that the condensation drain line was clogged. Water had backed up into the safety switch and shut down the system. Options for repair were presented to the homeowners and they chose to have the drain line cleared and to sign up for maintenance. I cleared the condensation drain line and flow tested the drain with two gallons of water. Clear water was observed flowing freely out of the drain line. I function tested the system and the system was cooling with a 25 degree temperature split. The system is under a high heat load but was running at the completion of service.

Performed AC cooling check. Checked the electrical, mechanical, safety, and performance of the system. I cleared the condensation drain line and flow tested the drain with water. I also treated the drain line. The air filter was new and had been recently replaced by the homeowner. The condenser coil was cleaned. The capacitor on the condenser unit was reading 25 mfd on a 45 mfd capacitor. Options for repair were presented to the homeowner and he chose to have the capacitor replaced. I replaced the capacitor and function tested the system. The system was running at the completion of service.
