Knight heating did our basement furnace and ducting along with main floor air conditioning. an awesome job from start to finish. They went the extra mile with a few other related items that were never installed properly when the house was built. The crew was professional, cleaned up after themselves, explained what was being done and why, and exceeded all of our expectations. It’s was a pleasure having certified journeymen, who show pride in their work, complete our project. We would hire them again and highly recommend their services.
