Kellam is absolutely top notch! I have an Apollo heating system and the part that I needed was out of stock locally. They ordered the part, got it delivered quickly and set up my repair. Unfortunately I had some unforeseen problems from previous contractors working on the system which Kellam had to diagnose and fix. They sent a tech out on emergency service at 10pm, a master plumber the next am then finally an Apollo specialist that afternoon to get my system running properly. I feel that Kellam really went above and beyond what any other company would have done to get my heat running. Also their techs exhibit much more knowledge and experience than any other company that has worked on my house. If you have a HVAC or plumbing problem you can’t go wrong by calling Kellam Mechanical.
