Do I need a permit for hvac replacement or installation in Wheaton?
Yes. In Illinois, hvac replacement or installation generally requires a permit, and Wheaton is no exception.
Wheaton provides a Furnace and Air Conditioner - Residential guideline and requires a permit to replace or install heating and cooling equipment. New gas-fired equipment may require a combustion air calculation, and the work must meet the adopted 2024 code editions and the manufacturer's specifications. The mechanical contractor must be registered with the City of Wheaton. Confirm whether your specific replacement needs a permit with the Building and Code Department at 630-260-2050 before scheduling the work. 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.
