"Gave me an honest quote, ordered the equipment and installed the equipment when promised, very happy I used Integrity HVAC"

"Ted has helped me with both commercial and residential HVAC repairs. I am consistently amazed by the professionalism, helpfulness, and down to Earth helpfulness. I can not say enough about how impressed I have been with the service that I have received from Ted Cook HVAC!!!"

"Steve and Lee were great to work with. Super knowledgeable and took great care in their work. I got two quotes and theirs came in the lowest. Have already recommended them to friends looking for HVAC work. If you are looking for work that is done right and at a fair price, this is it."

"Very respectful and professionally completed fall service on HVAC. Our technician, Slavik, was on time and explained what he was doing and the results of his evaluation. Have used Sanders for many years and fully recommend them for all your HVAC needs."

"It went fine - identified a couple things on the upstairs HVAC unit and tested both systems"

"I sent a message through Angies List and they responded almost immediately. I was called and given a 30 minute window of their arrival, plus the technician's name. Then the technician called me when he was on his way. He talked to me then went to work and immediately diagnosed the issue (chipmunk chewed the wiring argh!). He gave me a quote which I felt was quite reasonable and the repair only took about 45 minutes. After that, we spoke further about the Hvac (it's pretty old), he said it seems to be running well but obviously has some age to it. He advised I don't need it replaced but may want to consider some ongoing maintenance. He was nice and professional and answered all of my dumb questions. I would definitely call them again.

"We recently had a brand new HVAC system installed by Chisholm, and the entire experience was excellent. From the initial consultation to the final walkthrough, their team was professional, knowledgeable, and easy to work with. They took the time to evaluate our home and helped us choose a system that fits both our space and our budget. The installation crew arrived on time, worked efficiently, and made sure everything was cleaned up afterward. They also took the time to explain how the new system works and answered all our questions thoroughly. Since the install, the system has been running smoothly—quiet, efficient, and keeping our home consistently comfortable. We’ve already noticed an improvement in both temperature control and air quality. If you’re in need of HVAC work, I highly recommend Chisholm. They’re honest, skilled, and truly care about the quality of their work and customer satisfaction."
