I had an intermittent problem with my furnace (some days it worked, other days it didn't). I saw the reviews here and decided to call Premier in the morning last week and they got a tech here by the afternoon. The tech, Adam M., fixed the problem and did a maintenance check in a little over an hour. I also liked that he explained and showed me what he was doing as he did it.
The furnace has been working great since then and I plan to call Premier again if I have another issue.
