Greensburg: Local Training, Real Equipment
Our recent visit to Central Westmoreland Career & Technology Center in nearby Youngwood put us face-to-face with the next generation of Westmoreland County technicians. The lab includes live furnace training units, condensers, air handlers and sheet-metal fabrication equipment—the same kinds of systems and components our team encounters in Greensburg homes, storefronts and office spaces.
High-efficiency gas furnaces, split-system air conditioners, heat pumps, boilers, air handlers and fabricated ductwork.

Recent Project — Greensburg, PA
ACiQ Mini-Split Installation in Greensburg, Westmoreland County
In September 2026, our team completed a ductless mini-split installation for a Greensburg-area homeowner looking for an efficient, flexible heating and cooling solution. We installed an ACiQ ductless mini-split system — a high-efficiency heat pump that delivers both heating and air conditioning without the need for ductwork. Learn more about our heat pump and mini-split installation services across southwestern Pennsylvania.
Mini-splits are an increasingly popular choice for Westmoreland County homeowners — particularly for additions, sunrooms, garages, and older homes where extending existing ductwork is impractical or cost-prohibitive. They offer precise zone control, quiet operation, and SEER2 efficiency ratings that can significantly reduce monthly energy costs compared to window units or electric baseboard heat.
Our technician commissioned the outdoor condenser unit on-site, verifying refrigerant charge, electrical connections, and system operation before leaving. Every installation we complete is tested to manufacturer specifications — not just connected and handed off.
Is a Ductless Mini-Split Right for Your Greensburg Home?
Mini-splits work well for a wide range of applications across Westmoreland County — from single-room additions to whole-home multi-zone systems. Common use cases include:
- Additions and sunrooms without existing ductwork
- Garages, workshops, and finished basements
- Older homes with radiator or baseboard heat and no central air
- Rooms that are consistently too hot or too cold
- Energy-efficient replacements for window AC units

Built to Last — From the Ground Up
We Invest in the Next Generation of Westmoreland County HVAC Technicians
Heirloom Mechanical was built on the belief that great HVAC work starts with great people — and great people need great training. That's why we actively partner with local career and technology centers, including Central Westmoreland Career & Technology Center (CWCTC) in Youngwood, PA, to connect with passionate students who are serious about a career in the trades.
We visit programs, talk to students, and recruit directly from the region's best vocational pipelines. When you hire Heirloom Mechanical, you're not just getting a technician — you're getting someone who was trained right here in southwestern Pennsylvania, mentored by our senior team, and committed to doing the job the way it should be done.
If you're a student or recent graduate from CWCTC, Westmoreland County Community College, or another regional HVAC program — and you want to build a career at a company that will invest in you for the long haul — we want to hear from you.
