Heating & cooling by town
Pick your town
Heating and cooling businesses help you keep your home comfortable through cold winters and hot summers. Many of the companies listed here offer furnace and boiler installation and repair, air conditioning repair, heat pump installation, and indoor air quality work. Towns include Milford, Branford, East Haven, West Haven, Farmington and Hamden, so you can compare providers close to where you live. When you choose one, ask whether they handle your specific system, such as a boiler or heat pump, and confirm they offer service calls on short notice. It also helps to ask for a written estimate before any work begins, and to check hours so you know when someone can come out.
