Do I need a permit for hvac replacement or installation in Romeoville?
Yes. In Illinois, hvac replacement or installation generally requires a permit, and Romeoville is no exception.
Furnace and air-conditioning replacement is reviewed under the 2021 International Mechanical Code and 2021 International Fuel Gas Code adopted by the Village. Gas and electrical connections must comply with the adopted 2021 IFGC and 2020 NEC. Contractors must be registered, bonded and insured with Romeoville before a permit is issued. Most Illinois jurisdictions require a mechanical permit to replace a furnace, air conditioner or heat pump, even for a like-for-like changeout. Gas piping, venting and any new electrical circuit normally require their own trade permit, inspection and pressure test. Which code edition applies is set by your municipality or county, because Illinois has no statewide residential building code for work on an existing home.
