South Side Plumbing & Heating provides licensed air conditioning repair, AC replacement, and ductless mini-split installation for homeowners and businesses in Mt. Lebanon, PA. As a Trane Comfort Specialist and Rheem Authorized Dealer, our registered Pennsylvania contractors (PA010066) deliver 24/7 emergency cooling services to keep your home comfortable through the hottest Allegheny County summers.

Many historic and mid-century homes in Mt. Lebanon rely on radiant heat and lack the ductwork required for traditional central air. If you are tired of relying on noisy window units, our ductless mini-split systems are the perfect solution.

We design and install high-efficiency, zoned mini-splits that provide whisper-quiet cooling exactly where you need it. Because installation requires only a small hole in the wall to connect the indoor and outdoor units, we preserve the architectural integrity of your home while drastically lowering your summer energy bills.

Whether your AC stops blowing cold air on a humid July afternoon or you are ready to upgrade an aging system, our master technicians are ready to deploy to your Mt. Lebanon property.
