Emerson was great. His maintenance review was very thorough, & he worked hard to check our systems. Highly recommend for a/c evaluations.
Gene was fantastic and provided information and education about electric heat pumps with which we were previously unfamiliar. Thanks, Gene!
Constantly good people that come to service our heating and air systems. ++++++++ Great communication from office for service reminder, & alert for on-the-way.
We were told there was a Freon leak and coil needed to be replaced, and a system overhaul was recommended. The estimate was more than the purchase of a new system though parts were still under warranty. We called in a second opinion same day. The leak was found outside. A fitting had been loosely screwed together, causing the leak. The leak detector immediately identified it. The coil was very carefully checked for leaks and none found. I guess Centex did not want to serve us in the future. Maybe because we’re 30 miles away?
Response from Centex Air & Heat:
Mr. King, as you're aware not all companies are created equal. We've been in business for 40 years and only employ the best techs and ensure that they are highly trained. We stand by our diagnosis and respectfully disagree with our competitor's opinion. You do have a leak on the indoor portion of your system and it will remain an issue that needs to be resolved. I went ahead and sent you the video that my tech took of his leak detector detecting the leak. I encourage you to show that to this other company and have them explain it.
Travis is a very professional young man. He is friendly and explains things so I can understand them. I always enjoy having him in my home. He has a way of delivering bad news in the least painful manner.
Top technician to check out minis & Central system. Very personable. & knowledgeable. Highly recommended.
He’s a 10, nice fellow, knows what he is doing and a good example of an employee.
From the ladies that answer the phones to the guys that do the service like Daryl W They are great they know their skills and really nice people to deal with.
Daryl is very professional and experienced tech! He explained everything to me and my options!
Comes when they say they will and does what they need to do.
I called late morning and the service guy was there a few hours later. Knew what he was doing of course, took care of the problem. Daryl Wilson Very knowledgeable and polite.
Diagnostic and repairs to be done. So far good impression. Repairs to be done after parts are in.
Arrived on location to swap out faulty blower motor shaft and pulley for RTU #2. After pulling blower motor assembly we were unable to get the Allen key shaft locking screws off. Broke 5 different Allen key the process of trying to get it loose. Could not use heat due to the rubber bearing outside shaft. Will return with hardened steel bits that will not break. Replaced remote sensor for unit number 8.
Upon my arrival I spoke with the customer about their concerns with the system not cooling. Performing my diagnostics I found that the voltage enhancement system has failed causing the outdoor unit to not operate. I spoke with the customer about their different options for repair and they chose to go with HN14E. I performed the approved repair installing a new voltage enhancement system, new voltage distribution system, added performance enhancement system, added DTK power protection, redid wire terminals, cleared leaves from inside the condenser, chemically washed the condenser coil then ran a performance and safety testing. System is operating within manufacture specifications at this time. Customer joined the maintenance program as well.
Upon my arrival in La Grange I did AC Maintenance. 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. Performing our diagnostics we found that the system is a negative pressure system and was not equipped with a vent after the ptrap as well as the water removal system was backed up. We spoke with the customer about our concerns, went over repair options and maintenance program. Customer approved HF3A and the maintenance today. We cleared the water removal system, installed a vent pipe and checked the system performance. Found everything operating properly at this time.
Upon arrival in La Grange, Mini split outdoor unit non-operational. Found bad inverter board due to voltage surge. Replaced board and tested compressor start-up sequence. System now cooling effectively across all zones.
Upon arrival in La Grange, Swapped aging unit with high-efficiency model. Installed new thermostat, sealed duct transitions, and tested airflow. Verified TXV function and checked for proper defrost operation. System now meets ENERGY STAR standards.
Upon arrival in La Grange, System not cooling due to low refrigerant. Found leaking Schrader valve. Replaced valve core, pressure-tested, vacuumed, and recharged to spec. Verified cooling operation and recorded a 21°F temperature differential.
Upon arrival in La Grange, Seasonal cooling maintenance included pressure readings, capacitor testing, and evaporator coil inspection. No major issues found. Static pressure slightly high—recommended ductwork inspection to reduce strain on blower motor.
Upon arrival in La Grange, Serviced three indoor heads. Cleaned washable filters, cleared drain tubes, inspected refrigerant line insulation. Verified compressor operation and inverter modulation. System passed all function tests without faults.
Arrived in La Grange for Conducted comprehensive tune-up. Measured voltage and amperage, cleaned drain line, and lubricated fan motor. Tested temperature drop across coil and ensured proper compressor cycling. System is performing at optimal capacity.
Arrived in La Grange for AC Maintenance, Investigated indoor head not responding. Found faulty thermistor sensor not signaling temp to control board. Replaced sensor and verified accurate feedback on display. Unit is cooling efficiently again with correct temperature modulation.
Arrived in La Grange for AC Maintenance, Diagnosed intermittent cooling. Found worn contactor causing voltage drop under load. Replaced with OEM part, tightened all high-voltage connections, and verified stable amp draw. Customer educated on electrical inspection intervals.
Arrived in La Grange for AC Tune-up. Replaced R-22 unit with a new R-410A 15 SEER system. Replaced line set due to incompatible oil. Installed matching coil, set system on leveled pad, and calibrated airflow at 400 CFM/ton. System now operates at 100% efficiency.
