Besson was contracted in early May to replace our aging central air system, We chose them over two…read moreother contractors because they also offered an inside duct sealing service that maximizes system efficiency. This was a 2 day project using the 1st day to remove the old system and seal ducts and day 2 to install and test the new system. They arrived on time with all the necessary parts and equipment to handle any potential problems. During the duct sealing process, it was determined that the existing duct structure had the equivalent of a 25.8 square hole. After sealing, this was reduced to the equivalent of a 2.3 square inch hole. IMPRESSIVE ! The new system was installed per plan and has been running well for over a month which includes one or two 90 degree days. It is so quiet that one can hardly hear it. The 3 man team were very personable, neat, efficient and explained things clearly as work progressed. If you need a CAC system, call Besson 1st before anyone else

Called Sullivan in Monticello, NY, to attend to a low water pressure warning on my combination HW…read moreheater/boiler. They came in the house and IMMEDIATELY warned that this code "usually means tankless water heaters are shot." Mind you, this system is only ten (10) years old and in good shape. After removing the cover and looking at the heater, they closed it again and left. According to the invoice, "Technician found the boiler should be replaced, there are several leaks, the heat exchanger has calcification. The unit has not been maintained in a long time and is beyond cleaning. Technician did currently leave it working but it will shut down again." I then get a bill for $159. The problem is, the heater WAS WORKING when they arrived, worked fine throughout their stay, and continued to work without any assistance from them. When I contacted another plumber, he found zero leaks, then explained the unit required nothing more than a heat exchanger and routine service and was nowhere near the end of its service life. Apparently Sullivan is more anxious to sell and install new heating system than to service existing ones fairly.
