"Angie, I was glad to find Advent on your web site. The technician did such a great job that I referred them to my friend who was having HVAC problems. Our A/C quit and I thought the problem was the thermostat so I changed it. The unit did not run. I wanted a company that served Eastern OK County & checked Angie's List on-line. Advent is in Choctaw OK and has a superior rating. I know why, now! The tech was running late and called to let me know, which I appreciate. When he arrived, I explained what I had done, saying that I had found the brown wire broken and reconnected it. He traced the wires and got the unit working. What really impressed me was that he doubled checked the unit at the heat pump and found that it was heating, not cooling. He went back to the furnace & thermostat, removed the brown wire, and reversed 2 other wires. He was very patient with me and answered all of my questions. I really enjoyed this experience. Two years ago, when I was very sick, I was "hooked" into a costly plumbing problem by a local contractor. I'll check Angie's List first. Oh, by the way, the original thermostat was defective and the one I installed was good. Thanks Angie, thank you Advent!!!"

"We are very happy with our decision to have Comfort Concepts replace our system. Mike came out and found that our compressor was shorted. He gave us several options and we decided to go ahead and replace the entire heat and air system due to it's age. Mike and his assistant were very punctual and arrived exactly when he said to start replacing the unit. They were here all day to replace all of the equipment and were very professional and courteous the whole time. When they were finished they cleaned up everything leaving the garage looking better than it did when they arrived. Mike took the time to explain the operation of the new unit and how to operate the new thermostat. Mike was very polite and made sure all of our questions were answered before he left. We do not plan on having to do this again for a very long time but when we do we will be sure to call Comfort Concepts and they will certainly be doing all of our service work from now on.

"They were extremely punctual for both the estimate, and the actual installation, with full explanation of how the machine works including the comparison between the cost of a tankless and a standard heater,. In addition, there has been some vibration noise (that only one member of the family can hear!) and they have been extremely thorough in working to lessen it, while being cheerful through the whole process, despite having to make extra trips to do so."

"Quick and thorough service, changed and disposed of old filter, gave advice re: heat pump."

"Great job. Quick, thorough and effective. All done remotely...
Would recommend and use again.

"The estimate indicated that the installation would require a separate circuit with the cost for this being more than I felt it was worth so I did not have the electrician install the fixture.  However, True Tech did allow me to use my deal on another job that they worked on.  I use them for my electrical, plumbing and HVAC work and find them professional and caring.

"I usually use a different company for regular A/C tuneups in the spring as well as furnace tuneups in the fall. Last Friday, that company performed a tuneup on my system and charged me for 2 lbs. of R-22, a capacitor and a hard start kit. My A/C was working just fine prior to their arrival and when they left it wasn't cooling at all. I called them again and they sent the same technicians back out only to be told that my compressor was shot shortly afterwards. It was going to cost me $6000-$7000 to replace the whole system since it was R-22. I have American Home Shield warranty service, so I called them and they sent out All Comfort Specialists. It didn't take Tony and Pat anytime at all to figure out that the inept technicians the other company sent had overcharged my unit which was causing the compressor to shut down when the pressure and amps reached too high of a level. Also, I already had a hard start kit, yet the other company decided to add another one. After Tony reclaimed the 2 lbs. of refrigerant, my unit started cooling perfectly as it had done before the tuneup. Needless to say, All Comfort Specialists just gained a new customer for the foreseeable future."

"The serviceman did a great job in installing the new burner. Did it with ease."
