NJM Mechanical & Contracting

NJM Mechanical & Contracting serves residential and commercial clients throughout New York City, delivering plumbing, heating, cooling, and general contracting solutions from a single responsive team. The business maintains a perfect 5.0-star rating across 55 client reviews, with customers praising both the quality of craftsmanship and the direct communication they receive throughout each project. Their 24/7 emergency line ensures that urgent situations, whether a failed water heater or a heating system breakdown, receive prompt attention.

The contractor distinguishes itself through full-spectrum capabilities that rarely appear under one roof. Their service menu covers everything from traditional boiler installations and gas line inspections to modern geothermal heating systems and radiant floor heating, giving homeowners options beyond conventional forced-air setups. The contracting division handles structural additions including dormer designs, home extensions, window installations, and full kitchen and bathroom renovations, work that many HVAC specialists farm out to third-party remodelers.

Reviewers consistently highlight technician Neil as the professional who manages their projects. One client described Neil arriving within 24 hours to replace a failed water heater, completing the installation the same day. Another homeowner recounted multiple projects over a year, from fixing a kitchen sink leak to installing a complete HVAC system with heat pumps, air handler, and dual-zone furnace, praising Neil for explaining each step and flagging concerns before they became expensive problems. A third reviewer noted Neil's kindness in warming an 87-year-old client's home during an emergency furnace failure.
