Our experience with this firm is limited to solar heating, and it is excellent. We had a solar panel installed by the owner, George Kitzmiller, about 30 years ago and have saved the price of the system more than 10 times over. The work was done expertly, the panel survived all the hurricanes we've had in Miami since then, and we have needed to call on him only to replace a small photovoltaic panel that runs the circulation pump, to disconnect and reconnect the solar panel when our roof was replaced, and now to patch a small leak at the elbow of the pipe on the roof. It's great for Miami and for the planet that he continues to be in business.
