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

We are very pleased of the two young men, Bret and Gary who came in to our home and got the job down. They were very... polite, seems like they never took a break, did not leave a mess, and respected our home. Knight Heating and Air Conditioning in our book needs a10 star review!!!read more

This company went above my expectations on service. In the begining of fall we had heater issues. The consumer service... at beginning and ending were outstanding. The tech was able to locate a motor and install within 24 hours.read more

Had another major company come out to diagnose my HVAC issue. They quoted me $600 for all kinds of repairs that didn't... sound right so I declined their service and called knight. Their tech Kevin came out and found the issue in minutes..... simple wiring problem. Total charge $80.read more
