Awesome company to do business with. Robert was an awesome technician
We had a great experience with this company! They installed our new AC units and also took care of some plumbing work for us. From start to finish, the entire staff and crew were friendly, helpful, professional, and a pleasure to work with. They took the time to help us choose the best options for our needs while…
We used Trust Heating and Air based on our neighbors using them and their great reviews. I can honestly say believe the reviews. Extremely affordable, great product and wonderful employees. The two men that installed our new unit were friendly yet professional, informative and very respectful. We couldn’t have asked…
The best ever very hands on , fast , and reliable!!
I was in desperate need of air and Robbie showed up on time, he was attentive, and he truly knows what he is doing. The price was affordable and he was able to temporarily get us air while we wait for the part to come in. I would definitely recommend Techmazing for your HVAC needs.
Amanda is extremely thorough and polite. She did my Spring and Fall maintenance this year, very attentive and arrived on time with all supplies needed. She found an issue with a condensate pump, had one on her truck and replaced the bad one, serviced my 3 units, changed all filters and cleaned the outside units.…
Danny did a great job! The entire staff was great. They were knowledgeable and professional.
Excellent work, Robert explained everything very thoroughly and knocked it out of the park.
Preston was awesome today, doing the Maintance to my restaurant. Outstanding!!
Danny is GREAT! By far the best customer service of any A/C company I’ve dealt with. Thanks Danny!
Danny was great.
Pablo was awesome repairing my ac!!!
The technician was very knowledgeable and friendly. He solved our issue, explained everything he was doing as he was doing it. I needed my air conditioner issue fixed, and that was exactly what he did.
Quan was great. Very nice and personable. He got to work quickly, and did a thorough inspection of my system to identify the issue. I couldn't be more happy with the way he answered my questions and resolved my issue.
Pablo was very sufficient and detailed . Great jib
Great service. Quick appointment time after i called in. It was 85 degrees in the 2nd floor of my house on the techs arrival, luckily it was an easy fix and the temp has dropping ever since. Decent pricing too, from the last time i had to call someone. Can't really complain about anyhting, great service, great price, quick resolution.
Never heard of Techmazing but another company was quoting over $5k for a dehumidifier for my attic. Robby came out and said he wouldn’t feel right about quoting a dehumidifier as what was needed due to the spray foam insulation was to condition the space which ended up being a little over $600. Honesty and…
Amanda was awesome. On time, fixed the clogged AC drain line and replaced the p trap. Completed everything in a timely manner and answered all of our questions. Great service!
Eric is great technician! He does a thorough job ! The first time!
Preston Was Very Fast And He Was Really Great
My home
Our A/C had gone out and was not blowing cold air. I contacted Techmazing and Joshua and Robert came out and they took care of the problem. Thank you Joshua and Robert and now we have cold air again. P
Amanda came and worked tirelessly to get our clogged drain cleared so we could get the AC back up and running. She checked in with me periodically to let me know the what the status was and answered any question I had.
White-glove treatment from start to finish, from every person there. Saved me from a terrible York and I couldn't be more pleased. Wish I could leave 6 stars. If you have found them, you are in great hands.
Amanda did an outstanding job with my A/C tune-up. She was professional, knowledgeable, extremely thorough, and took the time to carefully inspect everything instead of just rushing through the service. What impressed me the most was that she discovered a crack in one of the HVAC lines that had been missed by three…
Was able to make a same day appointment. Robert was very professional and knowledgeable. Helped get our AC back up and running quickly and educated on how to keep our units running properly. Will definitely recommend!
Preston was outstanding
Had to call in for warranty service on my Run-Tru heat pump. Technician Robert diagnosed the problem quickly and ordered the parts. He returned a few days later to install the parts and got us back up and running. Great job by Robert. I could tell he was a seasoned pro as soon as we started talking. Good to know…
We had our upstairs heat pump go out on us on a hot July Thursday. We had one company come out and give us a quote on a new system after determining that our current 12 year old unit wasn't worth saving. After the first company left, I contacted Techmazing around 6pm on a Friday and they indicated they would be…
The two technicians that serviced my home were professional and friendly. A lot of other home service companies examined my unit and wanted to sell me subscriptions or replace my water heater. My ac was down. I would use techmazing again because the prioritized what I wanted and not what they wanted from me. The…
