We have used Knight for 20+ years for our HVAC maintenance and repairs and have always been happy with their service. ... When it came time to replace our system we didn't think twice about who to call. Knight's team was exceptional. They made the whole process super easy and stress-free. Thanks to Ken, the guys that installed the units and a huge thank you to Stephanie!read more

Bret did a great job identifying the issue and clarifying the problem and walked me through the cost of replacement. It... was early evening so very late in the day for him, yet he was friendly and positive as he finished the repair work. He also gave me some cleaning tips that will help my system perform better!!read more
