Our furnace stopped working on the coldest night of the year. Day & Nite had a technician at our door within two hours. Diagnosed the problem quickly, had the part on the truck, and we had heat by midnight. Absolutely incredible service.
We upgraded from oil to a new heat pump with Day & Nite. The whole process — consultation, permit, installation — was seamless. The team was professional, clean, and explained everything. We’re saving significantly on our energy bills.
Day & Nite installed a ductless mini-split in our home office addition. They walked us through all our options, gave a fair quote, and the installation was done in a day. Great company — we’ll use them for everything.
