Maxwell TX Heating & Air Conditioning Services

On arrival, I spoke with the homeowner who informed me the system has struggled to keep up with the set temperature on the thermostat. I found the system slightly undercharged with refrigerant. Spoke with the homeowner and he approved adding refrigerant to the system. I added 12 oz of refrigerant and performed a leak search on the system. I was not able to find any signs of a refrigerant leak. The system may have never been charged properly from the initial install. The system is operational at this time.

Pumped down existing refrigerant to the condenser. Installed new TXV metering device at the evaporator coil in the attic. Installed new liquid line filter drier in the attic. Pressure tested system with nitrogen and pulled vacuum. Charged AC with R-410A refrigerant. Tested operation of system. Everything is working at completion of service.

Recovered existing refrigerant from the system. Installed new compressor and new wiring harness for the compressor. Installed new liquid line filter drier in the attic. Cleared drain with CO2 and primed trap with water. Pressure tested system with nitrogen and pulled vacuum. Weighed in factory charge of 5.6 lbs R-410A refrigerant. Charged AC to 9 degrees subcooling. Tested operation of system. Everything is working at completion of service.

Performed a/c tune-up on a Lennox straight cool system. Checked the electrical, mechanical and performance systems of the unit. Cleared, cleaned, flushed and treated the drain line and washed the outdoor coil. Did find the system has high static pressure. No other issues were found. The system is operational at this time.

Diagnostics found a faulty thermostat tripping the low-voltage fuse. I talked to homeowner and gave him options for repair. Customer chose to replace the thermostat with our Honeywell T4 series. I replaced the thermostat and programmed it. I then cycled the system on to verify proper operation. The system is cooling at completion of service.

AC cool check was completed for a horizontal straight cool system. Outdoor coils were cleaned. Condensation drain line was cleared and treated. All mechanical and electrical was checked and found within manufacturer specifications. The system is cooling properly at time of departure.

Service diagnostic found the outdoor capacitor has failed. I also found the fresh air filter is dirty. I removed the outdoor failed capacitor, installed a new capacitor and secured it with plumbing strap. I then function tested the system and everything is now operational.

Service diagnostic found the outdoor compressor wires were burnt at the capacitor connections and were preventing the compressor from working. It would be best to replace the capacitor since the capacitor connections were also damaged. Mr. & Mrs. Pineda chose to have the capacitor replaced. I replaced the capacitor and re-did all electrical connections that were damaged. Tested the operation of the system and found no other issues. The system is no

Cut in, framed and sealed with silicone new return air grille by the front door of the home. Installed soft start kit in the outdoor system cabinet. Tested system operation to ensure proper operation. Everything is working at this time.

My diagnostic found that the disconnect had burned up two wires, most likely due to being loose. I removed the burned up disconnect and installed a new disconnect. I then routed the wires into the new one and attached them. I turned on the unit and checked operation with emergency heat. The system is now working.

Heat checked completed on a horizontal gas system. Flame sensor was cleaned. Drain line was flushed and treated. Gas pressures were adjusted. All other electrical and mechanical components found within manufacturer specifications. The system is heating properly at time of departure.

Diagnostics found a failed outdoor torque booster. I went over repair options with the homeowner and he chose to have it replaced today. I relaced the torque booster and function checked the system. The system is operating properly at time of departure.

Trip 1 - Diagnostics found that the blower motor has failed. I did verify proper high voltage and low voltage. Presented options for repair and the homeowner has opted to have the blower motor replaced. Will need to leave to pick up new motor from the supply house. Trip 2 – Returned same day with a new blower motor. Replaced motor and cycled the system on to verify proper operation. System operational upon completion of repairs.

Built and installed new supply plenum with damper inside. Added new supports underneath the plenums to prevent same issue from happening again. Sealed all connections of the system with mastic and hardcast. Tested operation of system. Everything is working at completion of service.

Service diagnostic found that the outdoor capacitor had failed. I presented repair options and the homeowner chose to have the capacitor replaced. I replaced the outdoor capacitor and cycled power at the system. Filter was left out to allow the house to cool down faster. The system is operational at this time.

Service diagnostic found that the system was low on refrigerant. I performed a leak check and did not find a leak in the system. Options for repair were presented to the homeowner and he chose to have the system charged with refrigerant and to sign up for maintenance. I added 2.5 lbs of R410A to the system and brought the system up to the manufacturer specification of 8 degrees of sub cooling. The system was running at the completion of service.

Service diagnostic found that the condensation drain line had significant buildup. I checked over the rest of the system and the system was operating normally. Options for repair were presented to the homeowner. He chose to have the drain line cleared. I cleared the condensation drain line and flow tested the drain with two gallons of water. I then function tested the system. The system was running at the completion of service.

Duct Air Purifier Installation: Installed an advanced in-duct air purifier using ionization technology. Positioned the unit upstream of the blower for maximum air distribution and verified its operation with real-time particle count testing to show immediate indoor air improvement.

AC cool check completed for one horizontal Lennox system. Drain line was flushed and treated. Condenser coils were clean. No major issues were found. The system is cooling properly at time of departure.

Attic Insulation Installation: Upgraded attic insulation to reduce heat transfer, minimize energy loss, and stabilize indoor temperatures. This improvement helped lower energy bills and reduce strain on the HVAC system.

AC cool check completed on a horizontal Lennox system. Drain line was flushed and treated. Condenser coil was cleaned. All mechanical and electrical found within manufacturer specs. No major issues were found. The system was cooling properly at time of departure.

AC System Maintenance: Performed a comprehensive AC system maintenance, including evaporator coil cleaning, condensate drain clearing, coil fin straightening, refrigerant line inspection, and tightening of all electrical connections. This ensured optimal cooling efficiency, airflow, drainage, and electrical safety.

Started diagnostics and I found that the outdoor condenser fan motor was spinning backwards. I looked over the condenser’s electrical section and found that the run capacitor was swollen so I tested it and found it has failed when checked against a multimeter. I installed a new run capacitor and cycled power to the system. Checked and verified operation. Washed off the outdoor condenser coil (at no additional charge) and tested temperature difference between return and supply. I checked the 20x25x4 air filter and found it dirty causing an airflow restriction. Everything is working at this time.

AC Repairs: A client reported that their AC system was intermittently shutting off. After diagnosing electrical inconsistencies, I adjusted and tightened critical contact points, resolving the issue. The system now operates smoothly, providing uninterrupted cooling.

HVAC System Repairs: Responded to a service call regarding inconsistent indoor temperatures. Diagnosed and recalibrated the thermostat to ensure accurate readings and reliable performance. The homeowner now enjoys a well-regulated and energy-efficient heating system.
