I use InMotion Heating & Plumbing for my business and in my own house. They're great. People sometimes express concern about them being so expensive, but they're worth it. They are the best people around for hydronic heating. They are the most responsible and well-qualified. A real pro outfit. I've used others, but now I only use InMotion Heating & Plumbing. They're my guys. Not that many people do hydronics. It's fairly complicated. Some companies dabble, but the people at InMotion are really good specialists. I'm very picky, and my company only does high-quality work. InMotion makes the cut with me. It might take three months to get on their schedule because they are so busy, but they can also be flexible for certain situations. I highly, highly recommend InMotion Heating & Plumbing.
