When I was looking to replace my old water heater for a tankless, my research left me with a lot of questions since there is so much information out there. A self-help plumping store suggested Tankless Wizard. I called Tankless Wizard and they were very helpful. They came by and checked my electrical and plumping before giving me an estimate. Very professional and honest. They handled the electrical, plumping, and the permits. AWESOME … if I did it myself, i knew I would have missed something … like permits. A few months later I thought I needed an adjustment because the water was running cold and hot. They came and checked it out, removed it and took it to the manufacture which happen to be in Miami, they tested it, returned and re-installed it. There were no problems, just the temp was set to high. Made some recommendations as far as keeping the temp. It has been perfect ever since. AND they didn’t charge me for the second call. Unheard of right … well this is a sign of a true professional. They have me for every plumping job from now on. They even installed my new kitchen faucet.
