L & M Mechanical: New York and Long Island’s Trusted HVAC Partner

L & M Mechanical is a leading provider of HVAC services and maintenance across New York City and Long Island. Whether you're a tenant, building owner, or property manager, we deliver fast, reliable, and cost-effective solutions performed by highly skilled mechanics.

HVAC System Start-Up & Commissioning
Our proactive commissioning process ensures clear communication between owners, designers, and contractors. We verify that system designs meet the owner’s requirements, that all equipment is installed and functioning according to construction documents and manufacturer specifications, and that all devices are calibrated correctly.

HVAC Service Contracts
Regular service is key to avoiding costly breakdowns. L & M assigns a dedicated journeyman mechanic to your location—someone who knows your system inside and out—so any necessary repairs are handled quickly and efficiently by a technician who’s already familiar with your setup.

Exhaust System Service Contracts
We offer service contracts tailored to commercial-grade exhaust systems. L & M supplies specialty exhaust filters at some of the most competitive prices in NYC, including carbon tray filter reactivation services.

24/7 Emergency Service
Emergencies don’t wait—and neither do we. L & M Mechanical Services is available 24/7 to respond to urgent HVAC issues. We take pride in being there when you need us most.
