Kyle TX Heating & Air Conditioning Services

Performed cooling maintenance on one straight cooling system. Checked all electrical, mechanical and performance of the system. Cleared and treated the drain line and washed the outdoor coil. I replaced the high voltage wire nuts at the furnace which were undersized. The filters were replaced by the customer a week ago and are still in clean condition. I did find the outdoor condenser fan motor is leaking lubricant. I presented repair options to the customer, and she chose to have the motor replaced at this time. I replaced the motor and cycled power at the thermostat. The system is operational at this time.

Performed AC cool check. Checked electrical, mechanical, safety, and performance of the system. The air handler, evaporator coil and blower wheel are all clean. The wiring is tight and in good condition. The drain line was cleared, and flow tested with two gallons of water. The drain line then was treated. The condenser fan motor and contactor are in good condition. I treated the inside of the electrical cabinet with JS insecticide to combat ants/insects from getting into the contactor. The capacitors are within value. The refrigerant charge is within factory specifications and is cooling with a 16-degree temperature split. The condenser coil was cleaned. No major issues were found, and the system is running at the time of departure.

Returned to site and replaced the faulty blower motor with a new OEM motor. After installation the thermostat was cycled and set to 74 degrees per customer’s request. The unit is cooling properly at this time.

Performed cooling maintenance on a straight cool system. Checked all electrical, mechanical and performance of the system. Cleared and treated the drain line and washed the outdoor coil. The filter is dirty, and I offered to replace it but the homeowner said he would take care of it. I found that the blower wheel is dirty. Also recommended the installation of a water safety switch on the secondary drain line to prevent any overflow into the secondary pan. The outdoor capacitor is below value on the herm side. The condenser fan motor is leaking lubricant, and the system is slightly overcharged with refrigerant. I spoke to the customer and presented options for repair. They chose to only have the capacitor replaced at this time. I replaced the capacitor and cycled power at the thermostat. The system is operational at this time.

Installed Carrier gas system. Installed Honeywell T6 thermostat. Installed new supply and return plenums and sealed all connections with mastic air lock. Rebuilt and insulated primary and secondary drain lines. Added SS3 safety switch. Cleared drain and verified drain operation. Replaced secondary drain pan. Replaced disconnect and whip at outdoor condensing unit. Pressure tested with nitrogen and pulled a vacuum on the line set. Verified charge was at manufacturers specifications. Tested the system in both heating and cooling and it is working properly at this time.

Cool check completed on a horizontal heat pump system. Found biological growth inside the air handler. The drain line was cleared and treated. The float switch was tested and is operational. The outdoor heat pump coils have been cleaned. Amp draws were checked and are within range. The capacitor and fan motor are both in good shape. The contactor is original and shows signs of charring and pitting. Checked temperature differential on the unit and found that to be within range. No other major issues were found.

Began the diagnostic and I found that the outdoor condensing unit breaker was tripped at the main panel. When I went to inspect the breaker, I found that it had burned up. Spoke with homeowner and we decided to replace the breaker. Installed one new 30A breaker at the panel. Added in aluminum oxide compound at the breaker lugs and the disconnect lugs as the old compound had dried up so there was none present. Reset power to system and checked over everything. Verified everything was operating within manufacture’s specifications for operation. Everything is working at this time.

Performed semiannual maintenance on one straight cool HVAC system. Inspected all Performance, Mechanical and Safety Systems. Tested and verified that both the upstairs and downstairs zone dampers are operating as designed. Flushed and treated the primary condensate line. Cleaned the outdoor condensing coil out as some dryer lint from the vent next to the unit had made its way onto the coil. Everything is working at this time.

Installed new Carrier 3-ton heat pump system. Installed new Ecobee Lite thermostat. Rebuilt and insulated condensate drain line. Added SS2 and SS3 safety float switches. Cleared drain line with CO2 and flushed drain with water to ensure proper operation. This was then followed by Viper drain treatment. Installed new filter dryer, pressure tested with dry nitrogen and pulled a vacuum on copper line set. Replaced the condenser pad. Replaced the disconnect and electrical whip. Also ran the low voltage in Seal-Tite. Replaced both the supply and return plenums and then sealed with a mastic airlock. Charged system to factory spec and performed a benchmark. System is working properly at time of departure.

Performed AC cool check. Checked electrical, mechanical, safety, and performance of the system. The drain line was cleared, and flow tested with three gallons of water. The drain line was then treated. The blower wheel and evaporator coil are both clean. The wiring is tight and in good condition. The condenser fan motor is showing signs of overheating. The refrigerant charge is within factory specifications. The contactor is in good condition, and the capacitor is within value. The condenser coil was cleaned. No other major issues were found, and the system is operational at this time.

On arrival, the customer stated that the thermostat has been blank since Friday night. Began diagnostic by checking for low voltage at the thermostat and found 0 V. Went upstairs and found the furnace control board indicating an open fuse on low-voltage wiring. I shut the power off to system and went outside to inspect the thermostat wire where I found a rub out inside an electrical box. Rewired the low-voltage condenser wires, replaced the fuse and cycled the system on. I monitored the system for approximately 15 minutes and found no other major issues. The system is operating properly at this time.

On arrival I spoke with homeowner and she stated that the outdoor unit would not turn on anymore. I went into the attic and verified that the emergency overflow drain line was empty. I then turned the thermostat to COOL mode and went outside. I found that the unit was not running, however the contactor relay was energized and pulled in. I found that the breaker for the outdoor unit was tripped. I checked and verified that the compressor was not shorted to ground, and then found that the run capacitor has failed below value across both the HERM & FAN terminals. Installed a new run capacitor at the outdoor unit. Made sure the wire terminals were properly secured and fitted appropriately as some had become loose. Reset power to unit and checked over everything. Everything is working at this time.

Service diagnostic found that the thermostat has failed. The thermostat is receiving power but is not passing power to the Y wire to run the condenser unit. I removed the thermostat and bypassed it to test it with a jumper. The system came on and was running. Options for repair were presented to the customer and she chose to replace the thermostat. I replaced the thermostat and function tested the system. The system is running at the time of departure.

I went through the thermostat and noticed it was roughly 4 years out of date on the software. Went to update the software and when the thermostat would reboot to load up, the screen would go blank. I installed a different thermostat on the wall to test the system and was able to get my tester thermostat to run through all functions and reboot as normal. I recommend having a new Infinity UI Controller installed for the system to operate as designed and to be able to connect to WiFi. Homeowner agreed. Installed new Infinity UI Controller, connected to Wi-Fi and the smart phone app for remote control of the unit. Also ensured emergency water safety switch was enabled in the service menu and turned off the schedule/program feature for the homeowner. Ensured the app was successfully controlling the thermostat, along with updating thermostat to the latest software. Everything is working at this time.

Performed cooling maintenance on a heat pump system. Checked all electrical mechanical and performance of the system. The drain line was extremely clogged up. I cleared the drain and the primary pan. I poured three gallons of water into the drain and confirmed it is draining properly, I then treated the drain. I washed the outdoor coil and replaced the filter for the customer. I did find that the secondary pan is extremely rusted. I spoke to the customer about having the pan replaced and a water safety switch installed on the secondary drain to prevent any water overflow into the secondary pan. No other major issues were found, and the system is operational at this time.
