Lockhart TX Heating & Air Conditioning Services

On arrival, I found the emergency water safety switch tripped due to a restriction inside the primary drain line. Removed power from system, blew out the primary drain line and flushed drain line out. Verified drain had proper flow of water and then treated the primary drain line with a drain treatment. Opened up the indoor air handler and cleaned out the primary drain pan and treated with a drain treatment inside the drain pan. Reset the cooling system and inspected all Performance, Mechanical and Safety Systems. Verified everything was operating within manufacture’s specifications for operation. Everything is working at this time.

Performed diagnostic. I found that the primary drain line was clogged and tripping the float switch. I cleared and treated the drain and tested it with a gallon of water. I ran the system for 30 minutes and no other major issues were found.

Installed new Carrier condenser and new TXV. Installed a new liquid line filter dryer, pressure tested system with dry nitrogen and pulled a vacuum on the copper line set. Replaced extended supply and return plenums and sealed with mastic air lock. Added 3 new return air filter grilles in the bedrooms. Replaced disconnect and whip at outdoor system. Charged system to factory specifications. System is working properly at time of departure.

Air Conditioning System Repair. Performed service diagnostic. Diagnostic found that the system was performing poorly. Sub cooling was very low, and the temperature split from return to supply was 8-10 degrees. Design sub cooling was checked through the service application on the thermostat control and the system determined a designed sub cooling of 18 degrees. Two pounds of R-410A was added to bring the sub cooling up to 18 degrees. Temperature split had improved to 14-15 degrees before I left. Return temperature was 70 degrees, supply temp was 55 degrees and outside air was 97 degrees. I asked the customer to monitor that system and let us know if it continues to have cooling issues. System was running at the time of departure

Performed the AC tune-up. Cleared and treated the drain line. Condenser coil clean. I did find that the capacitor on the indoor unit was below value. No other major issues found. Homeowner decided to have the capacitor replaced today. Repair complete and system is operational.

Installed customer supplied control board for outdoor mini split unit. Reset the cooling system and verified operation. Everything is working at this time.

Performed inspection. I found that the outdoor capacitor has failed. I also let the customer know that the condenser fan motor is showing signs of overheating. I presented the customer with options to repair and he chose to have the capacitor and the fan motor replaced at this time. I replaced both parts and cycled the thermostat. System is operational at this time.
