Commercial rooftop HVAC decisions, made before the next emergency.
Use the failure checklistA rooftop unit failure can turn into tenant complaints, operational disruption, rushed quotes, and an expensive decision made with incomplete information. HVAC DELVAN helps commercial property teams prepare the right questions and compare repair and replacement paths.
Clear boundary: HVAC DELVAN is an independent commercial RTU information and intake operator in a temporary launch regime. It operates under the HVAC DELVAN brand while legal entity details and a public business address are pending. It accepts requests only for preliminary qualification by authorized commercial property representatives. It is not an HVAC contractor, emergency dispatcher, or contractor recommendation service, and it does not perform or promise repairs, field visits, or contractor selection.

Packaged systems are common in commercial buildings
The U.S. Energy Information Administration reported that packaged air-conditioning units were used by 55% of commercial buildings with cooling in its nationally representative 2018 survey. That makes rooftop and other packaged equipment a useful, specific starting point—not a claim that every building uses the same system.
