Last spring I bought a home with a pellet stove and I didn’t have a clue how to turn it on let alone use it. I didn’t know who to call but after doing a Google search I found Tri-County Hearth & Patio/ Magic Broom. I have to say that I am a little weary when it comes to service companies because I never really feel like I am getting what I am paying for. The Tri-County technician arrived at my home on time, in a lettered van, and a clean uniform. He took me through everything I needed to do to properly run and maintain my stove. The best part was that he didn’t talk down to me or get frustrated even after the million questions I asked. I would highly recommend this company to anyone.
