"I was given Integrity HVACs information after searching Greenville for a reputable HVAC company and having no luck. Robert was easy to communicate with and provided a thorough estimate same day of arrival. We were able to schedule our HVAC replacement by that week! We live in a 1930s home and also had significant duct work issues in the basement. They were able to get me an additional estimate & complete the work within the same week. They were thorough, efficient & professional. We will absolutely use them for future work at our home. Thankful for Integrity!"

"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."

"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."

"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."
