Recent Review: For new system, needed two wells drilled 440 feet each. Connecticut Valley Artisan Well drilled the wells. They started in June and were done in July. Claude had the new units delivered to the house in July, and a week or so later he installed them. He removed the old water heater and put in a new electric one that will be incorporated into the geothermal system. They also removed the old furnace, oil tank, old condenser. They hooked up the unit in the cellar first to make sure we didn't go a day without air-conditioning! The second unit was installed in the attic to service the second floor. New vents were installed in the ceiling of the master bedroom, master bath, hallway and guest bedroom, incredibly with no mess! The new system was working perfectly for hot water and air conditioning. No more oil bills! We didn't use the heat until October. The humidifier wasn't working. We called Claude and he returned within a week to fix it. In January, there were four or five days where the temperature was near zero. The system was having trouble keeping the house warm. We called Claude and he was at the house with in two days. He realized the one of his subs - the guys who put in the duct work in the attic didn't remove the old ducts from the cellar to the second floor. The downstairs system was trying to warm both downstairs and upstairs! Claude and his son were there the next week to remove them. Major improvement! He also sent his son back a week later to seal all the duct work in the cellar free of charge. It was a pleasure to work with Claude. He solved our second floor air conditioning problem, by adding the unit in the attic. We are extremely pleased with our new system and with the work Bisson Plumbing did!
