RTU replacement
engineered for
Brooklyn
buildings, done right

As a general guideline, units over 15 years old, facing repair costs approaching half the replacement cost, or experiencing repeated failures of the same component are usually better candidates for replacement. Denair's technicians give you a straight recommendation during any Brooklyn service call, weighing repair cost against remaining unit life.

Yes. Denair coordinates the engineering drawings and NYC DOB filing process required for rooftop equipment replacement, managing the paperwork alongside procurement and installation scheduling so your project isn't stalled waiting on approvals.

LL97 sets carbon emissions limits for Brooklyn buildings over 25,000 sq ft, and an aging rooftop unit is frequently a building's least efficient major system. Replacing it with a modern high-efficiency unit is often the single biggest available lever for reducing HVAC-driven emissions, and we can model the specific impact for your building before you commit.

Cost depends on unit tonnage, rigging complexity, ductwork and electrical tie-in scope, and whether new permit filings are required. Every project starts with a fixed, itemized proposal after a site assessment — there are no hourly surprises once the scope is agreed.

Timeline depends on permit approval speed, equipment lead time, and rigging logistics, but straightforward single-unit replacements often complete installation within one to two days once the unit arrives on-site and permits are approved. We build the project schedule around equipment lead time from the start to minimize downtime.
