“My uncle told me to use this company after his best friend recommended them. My furnace wasn’t working and the air conditioner looked bad. They sent two get technicians to assess the situation and they advised me that our furnace and air conditioner were goners and they would have to be replaced. We decided to get a few quotes since this would be a large purchase. The first company came in the morning and the rep looked around inspected the old system and left. The knight was sent inspector was VERY through. He counted all our returns, double checked the ducting in the attic and educated us on systems and learned our preferences. What a difference!! Our mechanic room was not set up correctly and Ken explained how we could fix it and why some tweaks would go a LONG way. We were so thankful. Ken was amazing. The team showed up on Tuesday and they were efficient and kind. They protected our floors and worked together to get all the systems in and running smoothly. We will be telling all our friends about this group – they treat you better than family!

“Knight Heating & Air came to our rescue during a very hot holiday stretch. They gave us temporary comfort with a portable unit to get us through to installation day. But the best comfort of all was the specialists who gave us a comprehensive quote with options & answered all our questions. The install team was equally impressive & fully prepared to solve any problems & make things look nice. When I told my neighbor about Knight Heating & Air, he said that was who had installed a new unit for them previously. The people at Knight Heating & Air are truly ‘comfort specialists’!”

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
