Heating and cooling in St. Petersburg
St. Petersburg's building fee schedule, revised 10/1/2017, lists an air conditioning unit changeout at $65.00, the same figure it gives for other mechanical work with no plan review and one inspection. It's an older schedule. Work outside those lines is priced by valuation: 50.00 up to 1,000.00, then 7.00 for each additional 1,000.00 for single family homes and duplexes. Construction Services and Permitting is in the MSC Building, 1 4th St. N.
Call 727-893-7231 for the main line. The ePlan help desk is 727-893-7230, and plan review requests have gone through the online Building & Permitting portal since November 1, 2023. Under HB 803, in effect since July 1, 2026, the city offers a Permit Exemption form for single-family work totaling less than $7,500. That leaves out mechanical work. So are structural components, electrical, plumbing and gas work. The city's page sends license checks to the Pinellas County Licensing Board, and its codes link (effective Dec. 2020) names the Florida Building Code without an edition.
Here, 62.8% of occupied homes have owners living in them, and the median year built is 1969 (ACS 2020 to 2024). A single-family or duplex changeout takes the $65.00 line. Other work goes by valuation.
What heating and cooling work costs near St. Petersburg
Nobody's given us a quote for work in St. Petersburg yet, so this page can't show a city price. The Florida page lists the estimates with what technicians earn (the Florida mean in May 2025 BLS wage data is $27.55 an hour, which is their pay, not your price) and some city and county permit fees. How we estimate costs.
Permits for heating and cooling work in St. Petersburg
Florida cities and counties issue the permit for replacing an air conditioner, heat pump or furnace, and each sets its own fee; the state's $7,500 small-job permit exemption leaves out mechanical work. DBPR certifies or registers the air-conditioning contractor, so ask for that license number as well as what your permit office needs.
