San Marcos TX Heating & Air Conditioning Services

AC cool check was completed for a horizontal straight cool system. Outdoor coils were cleaned. Drain line was flushed and treated. All mechanical and electrical components were checked along with refrigerant levels. 21° delta T. No major issues were found. The system is cooling properly at time of departure.

Diagnostics found the heat pump disabled due to two issues. The outdoor defrost control board on the infinity system was replaced without replacing the model chip. I also found the second stage compressor plug not properly seated. The homeowner chose to have the issues repaired today. After repairs were completed, I checked the indoor unit for any issues. I did find the return trunk line essentially smashed open, allowing a massive amount of attic air straight into the air handler. At time of departure, the unit itself is running properly but without ductwork repairs the unit will be very inefficient cooling the house.

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. Replaced all return air filters for the homeowner. I secured the 14x24x1 filter grille. I also adjusted the register box in the back bedroom so the register is able to open and close freely. No other issues were found. The system is operational at this time.

Initial diagnosis found that the high voltage breaker tripped due to an air handler rub out. Once that repair was completed, I continued diagnostics, and I found a low voltage rub out popping low voltage fuse. I repaired that rubout and continued diagnostics. I went to cycle system to verify everything was running properly. At that time, I did find that the outdoor disconnect is faulty, not passing the proper voltage. Once the disconnect was replaced I did check refrigerant at homeowner’s request and found system to be very low on R-410A refrigerant. After adding the proper amount of refrigerant, I did verify the system was cooling before departure.

Service diagnostic found the outdoor fan motor capacitor had failed. This was preventing the fan motor from running and caused the compressor to shut down on a thermal lockout. I also found the outdoor fan motor has a hot spot (rust spot). Spoke with the homeowner and he chose to have the capacitor replaced. I removed both the compressor and fan motor capacitors and used a dual capacitor for both components. After replacing the capacitor, I cycled power at the thermostats and verified the system is operational.

Service diagnostic found that the capacitor on the condenser unit had failed. 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 operational and running at the completion of service.

Performed AC cool check. Checked the electrical, mechanical, safety, and performance of the system. I cleared the condensation drain line and flow tested the drain with two gallons of water. I also treated the drain line. No major issues were found. The system was running at the completion of service.

AC cool check was completed on a vertical heat pump system. Drain line was flushed and treated. Outdoor coils were cleaned. All mechanical and electrical components were checked. I did recommend to the homeowner to upgrade his air filters to a merv 8 in order to keep his air handler as clean as possible. No major issues were found. The system is cooling properly at time of departure.

AC cool check was completed on a horizontal straight cool system. Drain line was flushed and treated. Outdoor coils were cleaned. All mechanical and electrical components were checked. I did find the outdoor torque booster below manufacturers recommended value. I also found that while the condenser is running there is a slight wobble due to either the fan motor or the fan blade. Before leaving, the thermostat was reset to homeowner's preference. The system was cooling at completion of service.

AC cool check completed on a horizontal straight cool system. Drain line was flushed and treated. Outdoor coils were cleaned. All mechanical and electrical components were checked. I did find the outdoor torque booster well below manufacturer specifications. I went over repair options with the homeowner and he chose to replace the torque booster at this time. I replaced the torque booster and cycled the system on to verify proper operation. The system is cooling at completion of service.

AC cool check was completed for a vertical heat pump two stage system. Drain line was flushed and treated. Outdoor coils were cleaned. All mechanical and electrical components were checked along with refrigerant. No major issues were found. The system is cooling properly.

Installed Carrier 2.5 Ton furnace. Installed Ecobee thermostat. Installed new supply and return plenums. Sealed all connections with mastic air lock. Rebuilt gas line. Rebuilt and insulated primary and secondary drain line. Installed SS2 and SS3 safety float switches. Replaced secondary drain pan. Rebuilt flu pipe. Installed new disconnect and whip. Ran low voltage in 1/2 inch seal tite. Tested system operation and charged system to meet manufacturer specifications. Everything is working at completion of install.

Performed AC cool check. Checked the electrical, mechanical, safety, and performance of the system. I cleared the condensation drain line and flow tested the drain with two gallons of water. I also treated the drain line. The air filter was new and had been replaced before my arrival. No major issues were found. The system was running at the completion of service.

Performed AC cool check. Checked the electrical, mechanical, safety, and performance of the system. I cleared the condensation drain line and flow tested the drain with two gallons of water. I also treated the drain line. No major issue were found. The system was running at the completion of service.

AC cool check completed for a vertical heat pump. Drain line was flushed and treated. Outdoor coils were cleaned. All mechanical and electrical components were checked. Leak search performed to check for refrigerant leaks. I did find the outdoor contactor nine years old and showing signs of pitting. I also found the in rush amps to the compressor exceeding manufacturers limitations. No other major issues were found. The system was cooling at completion of service.

AC cool check completed for 2 straight cool systems and 1 heat pump system. All primary drains were flushed and treated. All three outdoor coils were cleaned. I found that the torque booster on the master bedroom heat pump is well below value. I also found high in rush amps to the compressor for the kitchen system. I went over my findings with the homeowner and he chose to replace the failing torque booster today. I replaced the torque booster and cycled the system on to verify proper operation. All three systems are cooling at completion of service.

Performed AC cool check. Checked the electrical, mechanical, safety, and performance of the system. I cleared the condensation drain line and flow tested the drain with two gallons of water. The air filters were clean and had been recently replaced by the homeowner. No major issues were found. The system was running at the completion of service.

AC cool check completed for a horizontal heat pump. Drain line was flushed and treated. Outdoor coils were cleaned. Checked all mechanical and electrical components. Everything is operating within manufacturer specifications. No major issues were found. The system was cooling at completion of service.

AC cool check completed for a vertical heat pump. Drain line was flushed and treated. Outdoor coils were cleaned. All mechanical and electrical components were checked and found within manufacturer specifications. No major issues were found. The system is cooling properly at time of departure.

Performed a/c tune-up on a Lennox straight cool zoned system. Checked the electrical, mechanical and performance systems of the unit. Cleared, cleaned, flushed and treated the drain line and cleaned the exterior of the furnace. Secured outdoor compressor wiring and washed the outdoor coil. The indoor coil is not the same tonnage as the outdoor system. This could lead to refrigerant leaks or other problems in the future. Also found the ductwork is causing high pressure on the supply side which is putting more wear and tear on the blower motor and other components. No other issues were found. The system is cooling at completion of service.
