Woodbury uses a combination permit. Separate permits will only be required on jobs where there is no related building permit. Check your building permit to see if it already includes the Heating, Ventilation and Air Conditioning (HVAC) Permit fee.
A HVAC permit is required for most HVAC work, including the installation or replacement of a furnace, air conditioner, fireplace, wood stove or HRV unit. For furnace replacement, a fresh air intake must be installed if not currently existing.
