CNM Heating Cooling Piping LLC

CNM Heating Cooling Piping LLC operates from Storrs, Connecticut, serving the surrounding communities of Mansfield, Willimantic, and the Quiet Corner region with round-the-clock heating and cooling expertise. The company holds a perfect 5.0-star rating across 186 client reviews, reflecting consistent delivery of professional HVAC service. Founded to address residential comfort needs throughout northeastern Connecticut, this contractor specializes in boiler replacement, central air maintenance, and modern mini-split system installations for homes across the region.

What distinguishes CNM Heating Cooling Piping LLC is their commitment to transparent service. Owner Mark and his technicians routinely waive diagnostic assessment fees when they determine a homeowner has been previously overcharged by another company. The team handles complex safety repairs involving fuel tanks and furnaces, addressing safety concerns that less experienced technicians often miss. Their installation work includes full house systems completed efficiently, with one crew finishing a two-floor setup in approximately five hours while thoroughly cleaning the workspace afterward.

Customers consistently mention technician Cody by name, praising his punctuality and systematic approach to annual air conditioning service. During the extreme heat of July, CNM resolved a frozen mini-split condenser that the original installer could not repair, restoring comfort when it mattered most. Another homeowner, a 45-year construction manager, specifically noted the crew's reasonable pricing alongside their technical expertise, confirming what he called their "top shelf" quality. The team also handled emergency safety repairs on a heating oil tank, addressing concerns that other contractors overlooked.
