"Because I work at night, I need someone who can come on weekends. Kannon booked us for a Sunday morning. They repaired the torsion spring and put in new weather seals. I was grateful they were flexible and professional."

"I'm in charge of a little warehouse just outside Charlotte, and we needed someone to put in some heavy-duty air ducts. Kannon's crew took care of everything, from giving us a quote to doing all the safety checks when they were done. They kept us in the loop the whole time, which was great. My only tiny wish is that the paperwork part could have been a little quicker. But overall, they did a fantastic job, and I would definitely use them again."

"They showed up on time and had the air duct fixed faster than I expected. Super efficient."
