"Fast service. I was planning a gift for my wife and the handle it First Class. Outstanding installers and great service. Thanks you for everything!! You got a customer for life. Thomas"

"These guys did a great job! I was called within 1 minute of requesting quotes for this job. I was given a reasonable quote promptly. Within a few days the unit was installed and is working wonderfully. I have to point out the technician that did the install. Josh was courteous and professional at all times. He stayed in contact with me thru the whole process. I would absolutely recommend this company and will to any of my neighbors that have such needs."

"The tech came out and spent a lot of time trouble shooting my HVAC issues. When the thermostat was determined to be the problem, he left a temp until Nest could mail me a replacement. After leaving a 4 star for quality I was called and harrassed why I didnt leave a 5 star review. I explained my reasoning, but the man on the phone wanted to argue and was obviously perturbed by the 4 star in that area. When I tried to get them to complete the work needed, he generated a quote that was 4x what I ended up paying from another company to avoid coming back out to the house. I didnt appreciate the way the phone calls were handled. The tech who came to the house was very polite, and explained everything to my wife so there was no misunderstandings."

"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."

"Jay is great. Did what he said at a fair price and worked late to get it completed. Highly recommend."

"It went well, the door installed the automatic garage door is working and the cracks in the foundation were sealed."

"They were quick to reply to my quote request and Blain arrived when they said he would. I noticed my water heater had gone bad around 11:00am and they had the new one installed around 6:00 the same evening. Blain was extremely nice, professional, and respectful and the work seems to be top notch."
