The Pittsburgh market

Pittsburgh splits the paperwork. Plumbing permits, including the replacement card for a new water heater, come from the Allegheny County Health Department's Plumbing Division, not the City. Furnaces, AC and heat pumps fall under the City's Department of Permits, Licenses and Inspections (PLI), which requires a permit to install, alter, repair or replace any mechanical or fuel gas system; swapping a minor part that does not change the equipment's approval is exempt. PLI's 2026 schedule charges residential permits $6 per $1,000 of construction value (minimum $130) plus a $4.50 state fee. Who may pull mechanical permits was not confirmed, so ask PLI. Pennsylvania's housing leans old: EIA's 2020 survey found 19% of homes heat with a boiler and 13% with fuel oil, while 52% use natural gas.

Only about 54% of Pennsylvania homes have central air, and boiler-heated houses often have no ducts for a conventional system. For a home without ducts, ask for a ductless heat pump quote as well, since it adds cooling and some heating in one installation. Where ducts exist, ask whether the coil on the furnace matches the new condenser. Get the SEER2 rating and tonnage in writing.
