"Completed the job on time and very efficiently. Very polite and easy to work with. Priced under most HVAC Companies. Would recommend again."

"It was covered under warranty. They actually installed our HVAC and it just wasn't cooling and it was a real simple thing that he was able to fix me up with. I have know them and used them for a long time. They are always prompt. They are very professional in what they do. They pick up after themselves. Very helpful in the information that he provides and making sure that any issues we are dealing with, he takes care of."

"Outstanding work. The crew was on time, respected my home, and was knowledgeable and professional. They ensured the system was fully functional and answered all my questions as they walked me through operations. Great team."

"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."

"Great job. Very friendly and informed me of my problem."

"I thought I had a hole in my ducts under the house which I was waiting to be told it's going to be expensive fixing. Video came over crawled under the house then asked to go inside. He went to the thermostat and pointed to my problem. I had the fan on even though I had the a/c off. It's a new thermostat and it wasn't fully explained to me how to use it. He could have come back telling me I needed new duct work, etc. Finding someone that's actually honest in today's world is very rare. I had him go ahead and clean my air vents and dryer out. He is to be commended for his honestly that I told my neighbor and she called to schedule her vents to be cleaned."
