Commercial HVAC is different from residential work in ways that matter: the equipment is larger, the stakes are higher when a system goes down, and the range of system types is broader. Heirloom Mechanical has the training and experience to service, repair, and replace commercial HVAC equipment across southwestern Pennsylvania.

Rooftop packaged units (RTUs)

Rooftop packaged units are the most common commercial HVAC equipment in the Pittsburgh region — found on retail buildings, office complexes, light industrial facilities, and multi-tenant properties throughout Allegheny, Westmoreland, Fayette, and Washington counties. We service all major RTU brands for repairs, preventive maintenance, and full replacements. Our recent RTU replacement project along the Route 30 corridor in Westmoreland County is an example of this work.

Commercial boilers

Many older commercial buildings in the Pittsburgh area heat with boilers — hot water or steam systems that require specialized knowledge to service safely and correctly. We service and replace commercial boilers for multi-family properties, office buildings, and light industrial facilities.

Commercial ductwork and air distribution

Commercial ductwork projects require design knowledge and fabrication capability that not every contractor has. We have completed custom sheet metal ductwork fabrication and installation for commercial build-outs in the Greater Pittsburgh area, including a full custom duct system for a light industrial facility in Monroeville.

Preventive maintenance agreements

Commercial properties benefit from scheduled preventive maintenance that keeps systems running efficiently and catches problems before they become failures. We offer maintenance agreements for commercial clients that include scheduled visits, priority service response, and documentation of system condition over time.
