We love Centex!! You have always provided a wonderful service! Your company has had to repair/fix another company’s MANY (air conditioner) problems. Our house is under 4 years old!(..finished December 2024). Everyone has been very professional and helpful- and the work is done in a timely manner. Thank you!😊 PS: Also like getting a photo and text when sending a service representative. Tell Travis thank you for us! He was awesome.

Upon my arrival in Lockhart, I found that the main refrigerant pressure control system in the A/C unit is faulted. I spoke with the customers about their different options for repair and they chose HI2D and signed the upstairs system up on maintenance. Will need to schedule a day to return to perform the repair. 2 techs about 3-4 hours. Customer has family coming at the end of the month and is hoping that we can return before then and ask if I can be one of the techs that returns.

Upon my arrival in Lockhart, I found the A/C system icing over pretty quick when I was checking pressures. I checked the indoor unit for proper air flow and found that the indoor air movement system is faulted. I spoke with the customer about his different options for repair and he chose to go with HC6A. Also spoke with the customer about the importance of having surge protection on the indoor system and getting on our maintenance program. He is going to think about it and make his final decision when we call to schedule our return date. Customer would like to be as late in the afternoon as possible when we do return because he works in Austin and will need a day heads up so he can plan for leaving from work. If he can’t leave work he is willing to open his garage remotely and can also control the thermostat from his phone. I would like to be attracted back to this for the return if possible. Customer will be without ac until this is fixed. This is an attic furnace

Responded to a service call in Lockhart for a non-operational furnace for a valued client. Upon inspection, identified a critical issue: a cracked heat exchanger compromising the system's functionality. Executed a prompt and skilled replacement of the damaged heat exchanger to restore the furnace to proper operation for the homeowner.

Performed the heating evaluation and found everything to be operating properly at this time. Client said that one of the rooms wasn’t cooling as well as the rest of the house. Took a look at the duct work and spoke with gene. We are going to add a return duct to the room and a damper to the 14inch supply coming off the front of the duct. Will need a 14inch start collar, 9inch start collar, 9 inch R-6 round duct, 9 inch bucket and a 12x12 stamp face grill.

Upon arrival to Lockhart, Tx., I recovered old refrigerant pumping system. Installed new refrigerant pumping system, filter dryer, and acid away. Purged and pressure tested the ac system with 300 psig of nitrogen. Pull vacuum to 300 microns. Replaced voltage enhancement system, voltage distribution system and wiring harness. Added 11 pounds of new refrigerant. After the repair turned the ac system on to cooling for 25 minutes and made sure that the sub cool was at manufactures specifications. Washed off the outdoor coil and let the client know the ac system is operating properly.

Upon my arrival to lockhart, tx., i found that there are two ac systems, and Older unit and a newer Goodman system. Found that older system is in bad shape and needs a lot of maintenance on it, the indoor heat transfer media is dirty and the outside system is too, the starting components are in rough shape and need replacing. On the newer system it also need a cleaning and attention to the outdoor system. Called customer and explained to him findings, he would like a estimate for a new system.

upon my arrival to lockhart, tx., I performed the one time system check on 2 attic heat pump ac systems and found that the downstairs ac system has a major leak in the heat transfer media coil. I spoke with the client about his different options and he chose the Hl1b. This will take 2 people 3-4 hours and the client has paid in full.

I found that the AC system was low on refrigerant and not cooling very well because of a leak on the indoor coil. I also found that the indoor system is leaning backward causing the water to fall out of the coil from the inside. I spoke with the client about his different options and I gave him a quote for a full system replacement. The client will speak with his wife and let us know what they want to do.

I found that the client was having troubles with 3 different air conditioning systems. AC System #1 which cools the unfinished downstairs area in the back and 2 rooms for the client in the front has no r22 refrigerant which I recommend replacement and the client has a consultation set up for 8/6/21 at 10am. HVAC System #2 which cools the upstairs and hallway also has no r22 refrigerant which I also recommend replacement but that system is not priority at this time. AC System #3 which cools the tenets office in the front is cooling but is older and has a dirty indoor HVAC system which I recommend cleaning and that they install a air filter in. This air conditioning system is satisfying the conditioned space but the two offices in the back are pretty hot because they run off of a different system that is completely down at this time (1).

I found that the system was not wired properly or set up for dehumidification and with the fan coil system or charged properly. Client wanted to go ahead and get the proper thermostat and set up properly with the correct charge. I replaced thermostat with an ecobee pro and set it the board up properly. After I charged the system with 2 pounds of r410a to achieve 10 degrees subcool. I went over the setting with the client and let them know that they may not be able to achieve the 40% humidity like they want but should have no problem keeping it in the high 40’s.
