What they do

Millas Heating & Cooling is an HVAC contractor based in Mystic, Connecticut. Air conditioning is the core of its work, and the company takes on both new installation and repair of cooling equipment. That makes it a fit for a household that needs a unit replaced before the warm months, or a fault fixed in an existing system. Its work is aimed at cooling problems that arise in summer, when a faulty unit can leave a home without relief. The business is open Monday to Friday and closed at weekends, so plans for a repair should allow for weekday visits.
