"Very dissatisfied. They tried to take advantage of an 80+ yo by not even completing a repair, produced a false image of a faulty (12 year old) heat exchanger at $99 wanting me to buy a new furnace. Thanks to website weeks of research and using my wood stove, info I was able to clean the condenser trap in 10 minutes and the furnace has been working for weeks, now."

"I was able to get the work scheduled quickly. The two workers were right on time. Good communication about what to expect. They did a great job sanding and painting exterior doors and trim. They had to move some items in the garage to get to the door, and put everything back just as it was. They cleaned up everything when finished. The workers were polite and respectful and kept me informed as they worked. Will definitely use Tri State again. Very happy with the quality work they performed. "

"Gas controller on my boiler was not working. Watkins responded and came within about 4-5 hours. The tech, Al, was very polite and professional. He looked at my controller, diagnosed that the problem was a broken spring and, since it's a "unique" and unavailable part, he modified the existing one and reconnected it stating he wasn't sure it would hold because of how stretched it was. It held for about 3 hours but broke again. I called Watkins again and they scheduled another tech since it was closed to after hours. My original tech took the call even though he was not on call. He had an idea for an alternate repair that has worked very well. I'm quite satisfied with the work and I believe the cost was reasonable. I highly recommend Watkins."
