Do I need a permit for hvac replacement or installation in City of Pittsburgh?
Yes. In Pennsylvania, hvac replacement or installation generally requires a permit, and City of Pittsburgh is no exception.
Under the Pennsylvania UCC installing or altering a mechanical system requires a permit, so a furnace, air handler, or air-conditioning changeout is permitted work in most municipalities even when it is a like-for-like swap. Emergency replacement of failed equipment may proceed if a permit application is filed with the code official within 3 business days. Relocating equipment or changing fuel or electrical connections adds scope, so confirm with your local code office. Pittsburgh regulates HVAC through a separate PLI Mechanical Systems permit (including fuel gas) filed in OneStopPGH; only portable heating, ventilation, or cooling units and replacement of a minor part that does not alter approval are exempt, so a full furnace or air-conditioner replacement is not exempt. The city maintains its own mechanical/HVAC trade licensing, so the work should be performed by a licensed Pittsburgh mechanical contractor, and permits tied to a licensed activity are suspended if the trade license lapses. A contractor performing more than $5,000 of home improvement work in Pennsylvania in a year must also hold PA Home Improvement Contractor (HICPA) registration.
