We are so happy that we called Joel and his team to repair our furnace. We were without heat for a week or so. We had contacted a few companies and none were able to properly diagnose our problem, instead we had 3 parts replaced and our heating system still did not work! Hundreds of dollars later we were lucky to be referred to Knowledge HVAC (and that is the perfect name for them, because they are quite knowledgeable!) Joel was able to come the same day and diagnose the problem for us. We hired him and his team to repair our furnace the next day, they were fast and efficient and we now have some heat finally! We are so happy we called them. I give them 5 stars for excellent service! I will definitely call them again if needed and will recommend them to my friends and family. Very pleasant experience, very nice guys! Reasonable rates.

I called around for a quote, and Knowledge was the first to call back. He gave a quote and was able to help the very next day. Joel and his team is very friendly, professional and knowledgeable. Very reasonably priced. I had a gas line system installed on my food truck. They did an awesome job, and put in extra time to get the job done on schedule. The inspector was impressed with the installation, passed the inspection with no problem. Definitely recommend them to anyone!!!
