The heat pump stopped heating because the compressor wouldn’t engage. After troubleshooting, I found the contactor was burned out. I replaced it with a new 40A single-pole contactor, tightened all electrical connections, and tested the system, which now operates correctly in heating mode for our client in Providence Village, TX.
During a routine heater maintenance visit in Frisco, TX, I cleaned the flame sensor on a gas furnace and replaced the dirty air filters. The flame sensor was covered in carbon buildup, which could have led to ignition issues. The system is now running reliably.
Responded to an emergency call for a malfunctioning heater during a cold spell. Diagnosed a faulty blower motor capacitor in a York heater. Replaced the capacitor, reset the system, and tested heating output to ensure reliable performance.
Repaired a Daikin DZ18TC heat pump that was tripping the breaker. The compressor's start capacitor had failed. Installed a new dual-run capacitor and checked the compressor amperage using a clamp meter. Verified that the unit operated without further trips.
Troubleshot a malfunctioning auxiliary heat system on a Rheem RP17 heat pump. The issue was due to a burned-out heat strip relay. Replaced the relay and tested the system in emergency heat mode, confirming proper auxiliary heat operation.
Replaced an old gas furnace with a high-efficiency unit. Disconnected the existing system and removed it carefully. Installed the new furnace, connected the gas lines, and tested for leaks using a gas leak detector. Completed duct sealing and thermostat setup.
I installed a new Goodman heat pump in Prosper. The old system was inefficient and outdated. After removing the old unit, I installed the new Goodman model, connected all the necessary lines, and ran system diagnostics. The new heat pump is working efficiently, providing optimal comfort.
Today, I completed heating maintenance on a Carrier furnace in Denton. I inspected the heat exchanger, cleaned the burners, and replaced the air filter. I also tested the gas pressure and verified the thermostat calibration. The furnace is now ready for the colder months ahead.
I performed heating maintenance on a Lennox Elite EL296 gas furnace in Denton, TX last evening, ensuring it was ready for winter. I started by inspecting the heat exchanger for cracks and cleaning the burners to ensure proper combustion. I replaced the air filter with a 20x25x1 high-efficiency filter and lubricated the blower motor. The flame sensor was polished, and the gas valve was calibrated for optimal operation. Finally, I tested the safety switches and thermostat for functionality. The system passed all diagnostic tests and was running efficiently, providing reliable heating for the customer.
In Aubrey, TX, I repaired a Trane XR95 gas furnace that was not igniting properly. I replaced a faulty igniter with an OEM part, cleaned the flame sensor, and inspected the burners for buildup. After testing, the system was operating efficiently and safely for reliable heating.
I completed a heat tune-up on a Carrier gas furnace for a customer in Krugerville. First, I inspected and cleaned the flame sensor and burners to maintain proper combustion. I then tested the blower motor for optimal airflow and ensured the gas pressure was within manufacturer specifications. I also verified the heat exchanger was free from cracks. Lastly, I adjusted the thermostat settings and tested the system’s overall operation to confirm proper heating performance throughout the home.
Repaired Lennox EL296V two-stage furnace with no heat complaint in Denton. Diagnosed failed pressure switch using digital manometer. Replaced switch with OEM part 103935-03. Cleaned flame sensor with fine-grit sandpaper. Verified inducer motor operation. Checked all limit switches. Adjusted blower speed for proper temperature rise. Cycled system through both stages to ensure proper operation. Restored heat to residence.
I completed an HVAC repair for a customer whose system was not functioning properly. Upon inspection, I found that the blower motor capacitor had failed, causing the blower to not start. I replaced the faulty capacitor with a new 35/5 MFD dual-run capacitor, then checked the motor for proper operation. Additionally, I inspected the evaporator coil and noticed dirt buildup, which was affecting airflow. After cleaning the coil and confirming the blower motor was running efficiently, I performed a full system diagnostic. The HVAC system is now working properly, providing consistent airflow and improved cooling performance.
I completed a ductwork repair for a customer who was experiencing reduced airflow in their home. After inspecting the duct system, I found several leaks and gaps in the duct joints, which were causing significant air loss. I sealed the leaks using mastic sealant and reinforced the connections with aluminum tape for added durability. I also wrapped sections of the ductwork with R-8 insulation to improve energy efficiency and reduce future air loss. After the repairs, I performed a pressure test to confirm that the system was now sealed. The home’s airflow is restored, and the HVAC system is running more efficiently.
I inspected an HVAC system that wasn’t cooling properly. The issue was traced to a low refrigerant charge, likely caused by a small leak. I recharged the system with refrigerant and used a UV dye to identify the source of the leak. The unit is now cooling effectively, and I will follow up to address the leak if needed.
I diagnosed and repaired a faulty Copeland scroll compressor in a Carrier 24ABC6 central air conditioner. After testing the capacitor and contactor, I found a refrigerant leak in the evaporator coil. I sealed the leak using Rectorseal AC Leak Freeze, recharged the system with R-410A refrigerant, and replaced the filter drier. The unit now operates at peak efficiency.
I addressed a Rheem RGGE-07EAUER gas furnace that wasn't producing heat. Upon inspection, I found a defective hot surface ignitor and a dirty flame sensor. I replaced the ignitor with a universal Silicon Nitride 120V model and cleaned the flame sensor using fine-grit sandpaper. I also replaced the air filter with a new MERV 11 pleated filter. After reassembly, I tested the furnace through multiple heating cycles to ensure proper ignition and heat production.
Completed a thorough air duct cleaning for a home with a Trane XR16 AC unit. Used a high-powered Rotobrush system to remove dust, debris, and allergens from the ductwork. Cleaned the blower motor, evaporator coil, and air handler to ensure optimal airflow and efficiency. Sealed any gaps and leaks in the ductwork to prevent future contamination.
