What your New Canaan neighbors say

“Our oil boiler quit after dinner on one of the coldest nights of the winter. Wilton HVAC answered right away, talked us through protecting the pipes, and had a tech out fast. He fixed a failed ignition component and stayed long enough to make sure every radiator was heating again.”
L Lauren M. Georgetown, Wilton · Boiler Repair
“We wanted to get off oil without making a mess of our older home. They laid out the pros and cons of propane versus a cold-climate heat pump, handled the details clearly, and the finished conversion came out cleaner than we expected. The house is more comfortable and the team was easy to trust.”
C Chris D. Cannondale, Wilton · Heating Conversion
“They installed ductless mini-splits in our old farmhouse where traditional ductwork would have been a nightmare. The heads are placed thoughtfully, the outdoor unit is quiet, and the crew protected floors and trim the whole time. It finally made the upstairs usable in both summer and winter.”
M Megan S. Silvermine, Wilton · Ductless Installation
