4th Gen Mechanical

Commercial & Other

Commercial rooftops, custom mechanical, and the work that doesn't fit a category.

4th Gen Mechanical builds beyond the standard residential install — rooftop RTUs lifted by crane, spiral ductwork in commercial buildouts, Lochinvar boiler rooms for small commercial buildings. If it's mechanical and it's in Monroe County, we can probably build it.

What we take on

The kind of work that lives here.

Most of our work is residential geothermal, heat pumps, heating, and cooling. But the trade has corners. When a commercial building needs an RTU swap, when a small business needs a Lochinvar boiler room rebuilt, when a buildout needs spiral ductwork run — those jobs land here.

Same crew, same standards, same family name on the truck.

  • Packaged rooftop unit (RTU) installs — York and equivalent equipment, including crane setting
  • Commercial spiral and rectangular ductwork — buildouts, renovations, and tenant fit-outs
  • Light-commercial Lochinvar boiler rooms — circulation pumps, valves, overhead distribution
  • Curb-mounted gas piping and refrigerant lineset routing
  • Custom mechanical work that doesn't fit a standard residential service category
  • Mixed-use buildings — homes with attached commercial space or multi-zone setups
