La Grange, TX

Upon my arrival the air movement system was cycling on and off. When I checked the voltage coming from the relay control it was opening and closing causing the issue. This is going to be the main cause of the system freezing over. With the customers approval I replaced the relay control and redid the wire terminals on it. I then tested the system and found that everything is operating properly at this time.

Arrived in La Grange for AC Repair, Upon my arrival I evaluated two mini split systems and one furnace straight, cool split system. I verified system safety and performance is to manufacture specifications. Flushed and treated the water removal system. Cleaned the electrical cabinet and washed unit using water. Found that the furnace split straight cool system was low on refrigerant. I performed a leak check with my electronic leak detector and found multiple signs of refrigerant leaks at the indoor unit. My recommendation was for scheduling an appointment with the comfort advisor regarding potential repairs.

Arrived in La Grange for AC Maintenance, Upon my arrival I performed a diagnostics on RTU#7 finding that the low voltage wire on one of the relays was loose causing low voltage to not reach the indoor air movement system. I pulled the spade connector off and crimped it to allow for a tight connection on the relay. Testing the system I found that everything else is operating properly at this time.

Arrived in La Grange for AC Maintenance, Upon our arrival we spoke with the customer about their concerns with the system shutting down.

Arrived in La Grange for AC Maintenance, Routine cooling check. Inspected blower wheel, measured temperature split (19°F), and checked airflow with anemometer. Found minor duct leakage in return plenum. Recommended sealing to improve system performance and reduce humidity.

Arrived in La Grange for AC Maintenance, Upon my arrival I spoke with the customer about their concerns with the HVAC system not cooling. Performing my diagnostics I found that the voltage enhancement system is faulted. I checked the plug on the refrigerant circulation pumping system and found that the wires had burned and the system went to ground. I spoke with the customer about the age of the system and gave recommendations on having a comfort specialist come out. Their consult is set up for 5/13/25 in the afternoon. Customer would also like options emailed one for repairs to compare.

Upon my arrival in La Grange, for an AC service, I installed the comfort control system. The system had to perform an update while I was on site. After the system updated I tested the equipment and found everything operating properly at this time. I was unable to get the app to work through the customer’s phone. I informed him he would have to contact the Support line to see if they can help get it hooked back up if they can’t Daryl says he will come out tomorrow.

Today I arrived in La Grange, for an AC service, with concern the outside heat pump does not turn on when the thermostat is in heating mode. Customers had previously found thermostat blank one morning. The indoor unit breaker was tripped, they turned breaker on and system was operational approximately 3 weeks at that time the thermostat was blank again so they installed a different thermostat. Since then the cooling works but in heat it doesn’t. I found thermostat was proper for the type of system they own. The thermostat model they had only allows operation for heat and cool, no auxiliary heating. I spoke with customer about heat pump systems and we also spoke about our maintenance plans.

Heat Pump Repair in La Grange, TX today for a great client. Specialized heat pump repair addressing intermittent system failure. Conducted comprehensive diagnostic assessment using advanced electrical diagnostic tools, identified and replaced faulty integrated control board, recalibrated system parameters, and verified full operational integrity through complete system performance test.

Today I arrived and met with mr and Mrs schock. I completed the HVAC Evaluation today of 3 systems. 90% gas furnace underneath home in crawl space, ductless living room unit and ductless bedroom unit. All 3 units perform very well and the safeties are proper. I washed both outdoor ductless condensers using water today and cleaned the indoor filters as well. I spoke with customers about performing cleanings on indoor units and installing Reme Mini Phi Purifiers for the ductless units as this can prolong the yearly cleaning intervals. Please email estimates, upon departure I left the central unit off and ductless units left on 72 in cooling.

Upon my arrival in La Grange I found that the coil was completely dirty and system had a build up of baking flower , recommend doing a cooling to coil, Phil approved repairs and I got the system back up and running. WO-TNFR353254

Today I arrived in La Grange and evaluated the customers concerns. Communicating system was completely operational with no active alarms or faults within the system, and it passed the refrigerant charging sequence. I contacted Daryl and he recommended that I reach out to Russell from tech, Russell tech-support Stated when the system ambient temperatures of 109 like yesterday, it is not going to keep up. Also verified all the data I had compiled through various tests. On the Mitsubishi system, I low pressures with customers approval. I added 2 pounds of refrigerant and then I performed a leak search. I found the indoor evaporator coil leaking refrigerant, Moving forward, I am awaiting pricing and availability from the manufacturer and will be calling the customer back once I receive it.

Upon my arrival changed all the filters and checked the leaking air ducts. Will be getting quotes together for replacing the diffusers in the back room of the bakery and the one above the table to the left in the bakery.

Recommended that they have a comfort specialist come out and quote them for a new system when I noticed that the pressures were a little off. For the temperature it is in the home and outside I had a high super heat showing me that the molecules are starting to break up on the refrigerant and not cool as well. Will need to set up a time for Daryl to come out and give them a quote for replacing the system.
