San Marcos TX Heating & Air Conditioning Services

Performed semiannual maintenance on three heating systems. Inspected all Performance, Mechanical and Safety Systems. On the vertical gas furnace in the basement, the gas line had five leaks in the piping connections from the flexible gas line to the furnace gas valve. I did go ahead and change out the 24x30x1 air filter and taped the edges inside the filter grille to help prevent filter bypass into the furnace. Presented my findings to the homeowner and he chose to move forward with the gas line repair. I completed the repair and checked for leaks. No leaks found and the system is operational.

Heating tune-up completed on an up-flow air handler/heat pump system. I did find that the contactor has some charring and pitting. I also found that the manufacturer’s hard start is below manufacturer specs. No other major issues found.

Heater tune-up completed on horizontal air handler/heat pump system. No major were issues found, and everything is running properly at this time.

Heat Pump Repair: A homeowner’s heat pump was failing to provide adequate heating, and the outdoor unit frequently shut off unexpectedly. Upon inspection, we discovered a faulty reversing valve that was stuck, preventing the system from switching between heating and defrost modes. We replaced the malfunctioning valve and tested the system to ensure seamless operation. With the repair completed, the heat pump now provides consistent warmth, keeping the home comfortable throughout winter.

Geothermal Heat Pump Repair Service: A client noticed their geothermal heat pump was struggling to maintain heat. Our inspection revealed a clogged heat exchanger, reducing efficiency. After cleaning the exchanger and optimizing the system, the heat pump restored consistent and effective heating. We advised the homeowner on regular cleaning to ensure optimal performance.

Performed a heater tune-up on one heat pump system. Checked all electrical, mechanical and performance of the system. Filters were replaced with customer supplied filters. I used my vacuum and hooked it to the drain line outlet by the condenser. I then poured 2 gallons of water in the primary drain pan and then treated the drain pan. I washed the outdoor coil and secured the compressor wiring to prevent any electrical rub outs. No other major issues were found, and the system is operational at this time.

Performed a heater tune-up on a Trane gas furnace 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. I replaced the high voltage wire nuts with a Wago wire connector. I did find that the gas outlet pressure at the furnace is high at 9.1in. w.c.. I lowered it to the rated 3.5in. w.c.. I also found the system has high static pressure but due to the location of the system there is no space for ducting improvements. No other major issues were found, and the system is operational at this time

Performed the heater tune-up on a Carrier heat pump 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 air handler system. Washed the outdoor unit and secured the compressor wiring.

Single system heating tune-up completed on a horizontal furnace. I adjusted the gas pressures to manufactures specs. No other major issues found.

Heating tune-up completed on a horizontal air handler/heat pump system. I did recommend a factory refresh on the condenser which includes a new contactor, capacitor, and condenser fan motor, as all these components are showing signs of age and deterioration. No other major issues were found, and the system is working properly at this ti

Service diagnostic found that the 5-amp fuse in the air handler was blown. I went through the wiring checking for shorts and did not find any. I went through the wires and did not find any frayed or exposed wires. I replaced the fuse and tested the system in cooling, heating auxiliary heating and fan modes. The system was operating normally. Once the system was operational, I performed a heat check on the system. Checked electrical, mechanical, safety, and performance of the system. I cleared the drain line and flow tested the system with two gallons of water. I replaced the filter with a customer supplied filter. No other major issues were found, and the system is running at the completion of service

Heating tune-up completed on a horizontal air handler. During my tune-up, I found that both plenums have partially detached. The ductwork also has multiple significant leaks throughout the entire system. In addition, I found that the disconnect for the condenser is not working properly. No other major issues found.

Performed heater tune-up. Checked electrical, mechanical, safety, and performance of the system. I cleared the drain line and flow tested the drain with two gallons of water. I then treated the drain line. I found some mold was growing inside the air handler around the evaporator coil. No other major issues found.

Autumntime HVAC Maintenance Service – To prepare for the colder months, I carried out a thorough cleaning of the heat exchanger and checked the furnace's heat strips. I also inspected the ductwork for potential air leaks, sealing any gaps to maintain consistent heating throughout the home. This preparation ensured the system was in top condition for efficient performance during autumn and winter.

Heating Repair Service – A property owner reported that their heating system was not producing adequate heat. During my inspection, I found that the heat exchanger was cracked, posing both an efficiency and safety risk. I replaced the heat exchanger and conducted a carbon monoxide test to ensure the system was safe for continued use. The heating system was restored to full functionality, providing reliable warmth.

AC System Repair – A homeowner reported that their air conditioner was emitting a burning smell. After a detailed inspection, I found that the motor's bearings were worn out, causing overheating. I replaced the worn bearings and thoroughly tested the motor to confirm that the issue was resolved. This repair ensured the AC unit would run smoothly without any further concerns.

Performed heater tune-up. Checked electrical, mechanical, safety, and performance of the system. I cleared the drain line and flow tested the drain with two gallons of water. I also treated the drain. During the check I found that the hot surface igniter is cracked and will not reliably ignite the furnace. Presented my findings to the homeowner, and Glen chose to have the igniter replaced today. I replaced the igniter and cycled the system. The system is heating properly after completion of repairs. No other major issues found.

Performed a heater tune-up on a Carrier gas system. Checked electrical, mechanical and performance systems of the unit. Cleared, cleaned, flushed and treated the drain line and cleaned the exterior of the furnace. I replaced the high voltage wire nuts with a Wago wire connector. We also reduced the fan speed in cooling mode which decreased the total static pressure of the system. No other major issues were found, and the system is operational at this time.

Completed installation of an all-new duct system. Installed new extended supply plenum and return plenums. Installed and sealed all new buckets and grilles. Raised unit on 8” vibration isolators. Created transition between furnace and coil. System operating at this time.

Performed the heat check on two systems. Checked electrical, mechanical, safety, and performance of the systems. The drain lines were cleared, and flow tested with two gallons of water each.
