Pittsburgh HVAC Permit

What's Required in Pittsburgh

• Replacing, modifying or installing heating, cooling, ventilation or fuel gas equipment needs a PLI mechanical permit.
• Like-for-like equipment replacements serving one home qualify for a one-day EZ permit with no plans.
• Outdoor units within 5 feet of a side lot line must be screened from the adjacent property to stay EZ eligible.
• Front-yard units closer to the street than the house and home generators need a standard permit.
• Portable units and self-contained systems with 10 pounds or less of refrigerant need no permit.
• The fee is $6 per $1,000 of value with a $130 minimum plus $11.50 in fixed fees; outdoor equipment adds zoning review.
• An HVAC/Mechanical trade license is required to install or replace any mechanical system in the city.
• Emergency replacements may be made first if the permit application is filed by the next working business day.

Do You Need a Permit to Replace a Furnace or AC in Pittsburgh?

Yes. PLI's mechanical permit page says a permit is required to renovate, repair, extend, modify or install mechanical or fuel gas systems, and that includes a like-for-like furnace or air conditioner swap. The good news is the EZ Permit pilot: replacing or installing listed heating, cooling or ventilation equipment serving one home, with the related ductwork, refrigerant lines, condensate drains and gas piping, qualifies for a permit with no plans, issued within one business day after the license information is verified. So does replacing an outdoor air conditioner or heat pump in its existing approved location.

Outdoor equipment carries extra conditions because zoning regulates it. To stay EZ eligible, ground-mounted equipment within 5 feet of a side property line must be screened from the neighbor, equipment in front of a porch or stoop must be screened and no closer to the street than the porch, and rooftop units must be screened from view. A unit in the front yard closer to the street than the house, an unscreened unit closer than 5 feet to a property line, or a home generator needs a standard permit. Only small things are exempt: portable heaters, fans and coolers, replacing a minor part, and self-contained units holding 10 pounds or less of refrigerant with motors of 1 horsepower or less, which covers typical window units.

How Much Does an HVAC Permit Cost in Pittsburgh?

An EZ permit costs the same as the permit type; PLI charges no extra fee for it. The 2026 residential base fee is $6.00 per $1,000 of construction value, minimum $130, plus a $4.50 state training fund fee, a $5.00 digital record retention fee and a $2 technology fee at the minimum. PLI's fee calculator adds a zoning review fee ($1.00 per $1,000, $50 minimum) when the work includes exterior equipment such as condensers. A $6,000 furnace: $141.50. An $8,000 condenser replacement: $141.50 + $50 zoning = $191.50. A $20,000 heat pump system that also needs a new circuit: $141.50 mechanical + $50 zoning + $141.50 electrical = $333. Those are PLI's residential rates; its permitting page puts attached single- and two-family dwellings in the commercial category, where the minimum base fee is $605, so confirm which category the portal assigns your house.

Who Can Pull an HVAC Permit in Pittsburgh?

A licensed HVAC contractor, in practice. PLI's licensing rules say an HVAC/Mechanical trade license is required to install, erect, enlarge, repair, alter, remove, convert or replace any mechanical system in the city; the license takes an ICC master mechanical exam and four years of experience and education. PLI's EZ page lists homeowners at a primary residence among those who may do residential EZ work, so if you plan to do it yourself, confirm with PLI before buying equipment. Wiring a new outdoor unit is a separate electrical permit.
