"Ducts were cleaned as we contracted for. When they finished the HVAC ducts they said they would do the dryer vent as a complimentary service. I told them I had recently cleaned it and they would probably not get much lint out of the vent. I was amazed at all they got out and it was at no additional charge."

"Tracy and Darren are excellent workmen for a great value. We had the best experience with Carolina Comfort Air Inc with these two workmen replaced our HVAC. Our response time was excellent and the job was completed within 24 hours. Tracy was very knowledgeable and teachable about our new HVAC. Definitely, would recommend them to others."

"On site within 2 hours of us calling. Very fast, professional, and affordable. The large HVAC company in our area was a 4 day wait, $125 just for diagnostics, and we have had repeated issues since they installed the units 2 years ago. Cardinal Mechanical was the opposite experience in every way."

"Lahcen is an excellent HVAC technician! He quickly diagnosed the issue with my AC unit and clearly explained what was causing an error in my AC unit and while he was diagnosing the main issue, he checked my filter he found out it was upside down. Professional, knowledgeable, and honest. I highly recommend him to anyone needing HVAC service."
