JM Heights Cooling Corp.

JM Heights Cooling Corp. has kept North Jersey comfortable since 1969, building more than five decades of continuous service as a family-owned contractor. Based in Yonkers, the company holds dual licensing , HVAC 9370 and Plumbing 12023 , and maintains a perfect 5.0-star rating across eight documented reviews. The operation serves residential, commercial, and industrial clients across the North Jersey corridor, handling heating, cooling, and plumbing from a single unified team rather than farming work to subcontractors.

What distinguishes JM Heights from typical HVAC contractors is their in-house mechanical engineering capability , they employ a staff engineer who performs custom system design and heat loss calculations, work most shops simply subcontract out. Financing through Synchrony opens immediate installation options for homeowners facing unexpected system failures, while their explicit policy of honest diagnosis with no unnecessary upselling directly addresses a frustration many callers have voiced about competing contractors. This combination of technical depth and transparent pricing creates a different service tier than standard replacement-and-installation operations.

Customer reviews name specific technicians and scenarios: Mitch and Romel installed a new heating system in March 2026, with the homeowner praising their workmanship. Jesus, identified as the company's plumber, receives repeated recognition for responsiveness , answering late-night calls and arriving promptly , and for completing repairs without recommending work the customer did not need. One heating repair customer noted the technician arrived on time, explained the issue clearly, and tested the system before leaving, emphasizing efficiency and professionalism throughout the visit.
