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

"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."

"I would highly recommend First Class for your heating and air needs. My AC went out and they were able to come the same day and fix the problem. Shelby who coordinates scheduling went above and beyond to schedule me that day. She was friendly, courteous and professional. Jonathan Pepper was the tech who came out and repaired my unit. He was knowledgeable, professional and had the best attitude. I could not have asked for better service."

"The techs were polite and very professional. Inspected & cleaned our HVAC ductwork and even provided photos of the inside of the ducts. No mess left behind. Very pleased and would hire them again."

"Excellent experience with George at Vent Service Pro. He arrived on time, worked hard all day, kept us updated with photos, and provided valuable HVAC maintenance and air quality tips. His professionalism and work ethic were impressive, and the quality of his work was outstanding. Highly recommended, and we will definitely use him again."

"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."

"They showed up promptly to access the problem and jumped right on the problem and ended up having to replace the whole system and they didn't quit til they repaired the damper system as well. Our HVAC has never worked so good! They could however work on keeping me informed of their arrival times. I had to call them each day they were expected to get an ETA."
