J&G Heating & Air Conditioning provides RTU installation, maintenance, and repair for businesses throughout Lancaster County. Each area receives the same quality commercial HVAC workmanship, emergency support, and commitment to minimal business disruption.
A rooftop unit is a complete HVAC system—heating, cooling, and air handling—packaged into one large outdoor unit mounted on your roof. Unlike split systems (indoor + outdoor), RTUs are “all-in-one” solutions common in commercial buildings.
