Commercial Rooftop Unit Replacement Along Route 30

Commercial properties along the Route 30 corridor in Westmoreland County depend on reliable HVAC to keep employees comfortable and operations running. When a rooftop packaged unit reaches the end of its service life — or fails unexpectedly — a fast, properly executed replacement is critical.

Heirloom Mechanical recently completed a commercial RTU replacement in this corridor. Our crew handled equipment staging, electrical coordination, refrigerant recovery, and full startup commissioning — with every step documented before we left the site. The photos here show our team working through the installation and reviewing the startup documentation on-site.

If your business in Irwin, North Huntingdon, or anywhere along Route 30 needs a rooftop unit serviced or replaced, we're the local team that knows this corridor and can respond quickly.
