Heating & Cooling Services by Windy City HVAC Repair

Joliet is the largest city we serve — 150,362 residents at the 2020 Census — and one of the most varied when it comes to housing. A single day of calls can take a technician from a century-old house near downtown to a 2005 build on the far west side. Windy City HVAC Repair serves all of Joliet, and we handle both.

Furnace and AC Repair for Joliet Homes, Old and New

Two very different Joliets

Older Joliet. About 15.7% of Joliet’s housing was built before 1940 — more than double the Will County share (6.9%) — and another 23% dates from 1940–1969. Homes like these come with their own HVAC challenges: furnaces retrofitted into spaces never designed for them, older or undersized ductwork, chimney venting that has to be checked when a new high-efficiency furnace goes in, and upstairs rooms that ductwork never properly reached.

Newer Joliet. At the other end, about 41.6% of Joliet homes were built between 1990 and 2009, much of it on the city’s west side. Those homes have standard forced-air systems — and many are running original equipment that is now 15–30 years old, which is right when furnaces and AC condensers start failing.

Heating and cooling in Joliet's historic neighborhoods

  • Joliet takes its history seriously. The city has two National Register historic districts — the Upper Bluff Historic District (352 buildings) and the Joliet East Side Historic District (257 buildings) — plus locally designated districts such as Raynor's Addition and Whitney Terrace. Near the Upper Bluff, the Cathedral of St. Raymond Nonnatus on North Raynor Avenue (completed in 1955) anchors one of the city's established residential areas, and downtown's Rialto Square Theatre, the 1926 movie palace on North Chicago Street, is a reminder of how long people have been building and living here.
  • For homeowners in these neighborhoods, HVAC work has to respect the house:
  • Adding air conditioning without tearing into plaster. A ductless mini-split needs only a small wall opening for each indoor unit, which makes it one of the least invasive ways to cool an older home. We install Rheem and Durastar ductless systems and can show you single-zone and multi-zone options.
  • Furnace replacements and venting. When an older furnace is replaced with a high-efficiency condensing model, the venting changes. We check existing chimney and flue conditions as part of the job.
  • Uneven heat. Older homes often have a few rooms that are always too cold. Sometimes it's airflow; sometimes a dedicated ductless head is the better fix.
  • If your home is in a locally designated historic district, check with the City of Joliet about any exterior-work review before you place an outdoor unit where it's visible from the street.

Joliet HVAC FAQ

Often the best option is a ductless mini-split system, which needs only a small wall penetration for each indoor unit. We’ll assess the house and walk you through the choices.

Older furnaces should be inspected for cracked heat exchangers, venting problems and carbon monoxide risks. If you smell gas or your CO detector sounds, leave the house and call your gas utility or 911 first.

Yes. We serve all of Joliet. Call (312) 500-4822 to confirm the earliest time for your address.

Possibly. In 2026, Nicor Gas lists rebates of $150 for a qualifying ≥95% AFUE furnace and $225 for ≥97% AFUE, and ComEd lists incentives of up to $1,000 for qualifying ductless mini-split heat pumps (up to $1,075 with a qualifying smart thermostat). Equipment and account requirements apply. Rebates are subject to change, and utility programs may end or change without notice. Eligibility is determined by the utility, not by Windy City HVAC Repair.
