Common questions
How much does a new HVAC system cost in Chicago?
A full central AC and furnace replacement in Chicago typically runs $8,300 to $23,500, with most homes near $15,800. Efficiency rating and home size set the price.
How long does an HVAC system last?
A well-maintained central system lasts about 15 to 20 years. Rising repair bills and uneven cooling are the usual signs it is time to replace.
Is a high-efficiency system worth it in Chicago?
In IL climates with long cooling or heating seasons, a higher SEER2 unit costs more up front but the monthly energy savings often pay it back over the unit life.

Not always. If the existing ducts are sealed and sized right, they can stay. Leaky or undersized ducts add roughly $3,000 to do correctly.
