Efficient heating & cooling
Heat Pump & Ductless Mini-Split Installation
Heat pumps and ductless mini-split systems offer efficient year-round heating and cooling for homes and businesses throughout Greater Pittsburgh. Heirloom Mechanical installs and services these systems throughout Allegheny, Westmoreland, Fayette, and Washington counties.
Systems We Install
Air-source heat pumps
Whole-home heating and cooling systems that move heat rather than generate it, offering efficiency advantages over traditional furnace-and-AC setups.
Ductless mini-splits (single-zone)
Ideal for additions, garages, sunrooms, or any space without existing ductwork.
Multi-zone ductless systems
Multiple indoor units connected to a single outdoor unit, allowing independent temperature control in different rooms or zones.
Cold-climate heat pumps
Modern heat pump technology designed to operate efficiently even in the cold winters common in southwestern Pennsylvania.

Project Spotlight — September 2026
Bosch IDS Edge Installation — Liberty, PA (Near Glassport)
Our install team just completed a full Bosch IDS Edge inverter ducted split heat pump installation for a homeowner in Liberty, PA — just outside Glassport in Allegheny County. The project included a new attic air handler and a complete whole-house ductwork retrofit, designed and installed from scratch to match the system's airflow requirements.
The Bosch IDS Edge is a compact, side-discharge outdoor unit with a variable-speed inverter compressor — it modulates continuously to match the exact load the home needs, delivering more consistent comfort and lower energy bills than a conventional single-stage system. For Pittsburgh-area homes, its cold-climate performance means efficient heating even when temperatures drop well below freezing.
