EPA removes the R-410A installation deadline for existing equipment
A May 2026 final rule lets residential and light-commercial systems built before 2025 be installed until inventory runs out. The 2025 manufacturing cutoff still stands.
Rental apartments, condominiums and mid- to high-rise residential towers. We deliver the electrical, mechanical and fire protection that every suite depends on, floor after floor.

A multi-unit residential building is hundreds of homes stacked on top of each other, each with its own power, plumbing, heating and cooling, ventilation and sprinkler protection, all fed from shared risers and central plant.
The same suite layouts repeat floor after floor, so getting the first ones right sets the standard for the whole building. Residents move in on a schedule, often while upper floors are still being finished.
Every sector has its own risks. These are the ones we plan around from the first meeting.
We prove out the first suites in detail, then repeat that standard floor by floor, using prefabricated assemblies where they save time.
Lower floors are often occupied while upper floors are still under construction. We plan risers, life safety and building services so each phase can be signed off on its own.
Duct, pipe, conduit and sprinkler lines share shallow ceilings and bulkheads. Coordinating them as one scope avoids clashes and lowered ceilings.

We review a mock-up suite with the developer, general contractor and design team before production starts, so questions are answered once rather than on every floor.
From there, each trade works to the same floor-by-floor sequence. Riser work, testing and inspections are planned alongside the general contractor’s schedule, so floors are ready when residents are.
