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.

Is a Heat Pump or Mini-Split Right for You?

Homes without ductwork: Ductless mini-splits are often the most practical solution for older homes, additions, or spaces where running ductwork isn't feasible.
Replacing both furnace and AC: A heat pump can replace both systems in a single installation, potentially simplifying your equipment and reducing long-term maintenance.
Specific zones needing independent control: Multi-zone ductless systems allow different areas of a home or building to be heated and cooled independently.
Efficiency-focused upgrades: Modern heat pumps can be significantly more efficient than traditional heating systems under the right conditions.

Project Spotlight

Recent Work in Dawson, PA

This Fayette County home needed a complete heating upgrade. Heirloom Mechanical installed a new heat pump system alongside a high-efficiency propane furnace, giving the homeowner reliable year-round comfort and a backup heat source for the coldest winter days.

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.
