I've been using Solvit Home Services for years. They've installed our furnace, a/c, water heater and most recently had them relight my water heater after it went out. The servicemen are knowledgeable and friendly and finish the job efficiently. I do have to say, though, that they're pretty expensive. It would be great if they could lower their prices. Besides that, Solvit Home Services is always reliable and does good work.
