"James Heishman came out to evaluate our existing system and inquired if we were having any problems with the system. We explained that the condenser fan was locking up and that we had observed numerous homes in the neighborhood had systems replaced this past summer. We were interested in replacing / upgrading our system before it fails during the summer. We also explained the lack of heat and cooling at one end of the house, James thoroughly inspected the house and how the ducting was arranged. After his inspection he made recommendations to rearrange the ducting, add another return line and add a damper to improve system operation.
That night he emailed three detailed proposals from a basic system, a mid range up to a more top of the line system. At no time did James ever pressure us to make a make a decision or what system we should get. He did answer all our questions and was very informative. After getting four other quotes form top HVLP company?s all ?A? rated here on Angie?s List, and had an A+ BBB rating, Moncrief not only had the best price but offered the best labor coverage.We decided on a 4 Ton Carrier Infinity 2-stage AC and a variable speed furnace with a Carrier Infinity WiFi thermostat installed. The install team ( Steve, Mike, and Herman ) were extremely professional and hardworking. They arrived at 9AM and didn?t leave till nearly 5PM. The duct work alone took all three men nearly 4 hours to complete. When the work was completed they thoroughly cleaned up any mess.  I could not be happier with the work accomplished. Rooms that had low air flow , now have great ventilation. Do yourself a favor and give them a call.

"I had an issue start last night on 8/3/26, I was contacted this morning by the office by phone call and asked if I still need service. By 930 or so Aaron showed up. Aaron is very polite and answered any question I had about the job so I proceeded with them. To me it was a catastrophic issue that needed immediate attention. Aaron completed the job of my entire upstairs drains being clogged with a few hours. I see some reviews stating they are pricey and that could very well be since I did want to wait around for multiple quotes that could have taken an extra day I went with them since they were the most responsive. Im happy that I am now back up and running, with multiple people in my home it was crucial to have the bathrooms back up and running. Thanks Aaron you made me feel at ease about allowing you into my home to help fix this issue."

"The entire process was great from start to finish! Ashley and Josh did a wonderful job helping me get everything set up. Brian and Brent helped me understand my options and beat the local competitors offer. Josh, Izaac, and Nick did an amazing job installing my new system. They worked quickly and quietly and left no mess behind. Everyone was so polite and professional. I highly recommend TE!"

"I had to get the drain lines in the house replaced. They were cast iron and over 50 years old. I had a number of contractors quote, but Luis Arvizu with TE Plumbing was the most thorough with the inspection of what needed to be done. He was professional- and in this environment it was refreshing to have a plumber not be condescending or try to upsell to a single woman. He and his coworker arrived on time, let me know the status throughout the work, and answered any additional questions I had about future projects. TL:DR the work was great and at a very reasonable price comparatively."
