About Liberty Mechanical
A Philadelphia-based commercial and industrial HVAC contractor built on integrity, craftsmanship, and long-term client relationships.
Who We Are
Liberty Mechanical Services Inc. is a licensed and insured commercial and industrial HVAC contractor serving the Philadelphia region and beyond. We specialize in the installation, maintenance, and repair of heating, ventilation, and air conditioning systems for commercial buildings, industrial facilities, and institutional clients.
Our team brings decades of hands-on experience to every project — from coordinating with MEP engineers on new construction to responding to emergency breakdowns in the middle of the night. We take pride in doing the job right the first time and standing behind our work.
Over the years we have built lasting relationships with clients across Pennsylvania, New Jersey, and beyond — including projects as far as Anchorage, Alaska and Bermuda. That track record speaks to the trust our clients place in us and the quality we deliver on every job.
