Village permitLike-kind replacement is on the Village’s no-permit list, but the contractor must be licensed and bonded with the Village. New equipment, new central air, a fuel or venting change, a relocation or new piping needs a permit. The Village’s express-permit page also lists furnaces and air conditioners, so confirm with Building & Zoning at (708) 714-3552 before work starts.

Ask every contractor
- Full model numbers: furnace, condenser, coil?
- Did the size come from a load calculation?
- Single, two-stage or variable, and why for my house?
- What duct work is included, and what if more is needed?
- How is it vented, and what happens to the water heater flue?
- Labor warranty in years, separate from parts?
- Installed cash price, and how long it holds?
What moves the price: Tier and ductwork move the number most. Venting and the water heater are the surprise items on 96% furnaces.
