HVAC Replacement Cost in Illinois
What it costs to replace a central heating and air conditioning system.
Overview
A full HVAC replacement swaps out your furnace and/or air conditioner (and often the ductwork connections) with a new, properly sized system.
Most homeowners replace both the furnace and AC condenser at the same time since they're designed to work together and tend to wear out around the same age.
Why Illinois prices differ
Costs run higher in the Northeast and West Coast due to labor rates, and lower in the Midwest and South. Homes in extreme climates often need larger, more expensive systems.
Frequently asked questions
How long does a new HVAC system last?
Most systems last 15-20 years with regular maintenance. Furnaces tend to last slightly longer than AC condensers.
Should I replace my furnace and AC at the same time?
It's often recommended since they're designed to work together, and doing both at once usually costs less than two separate service calls.
