Three months of real heat, and storms in between
Kankakee County asks for cooling from June through August. Summer afternoons average 83°F, warm enough that a struggling system falls behind fast once the sun's been on the house all day.
The county has also seen its share of rough weather, with 99 damaging wind events and 21 hail storms over the past ten years, one dropping hail 2.5 inches wide. An outdoor condenser sits exposed to all of that, so it needs to be installed solid and positioned with some thought. Any new central air conditioner installed since 2023 has to meet a federal minimum of 13.4 SEER2, so whatever goes in will meet that mark at least.

In Illinois, HVAC licensing for homes is left to the cities and towns.
That leaves it to Kankakee County and whatever city or village the house sits in to decide who can do this work. Some places keep a contractor list or their own licensing rule, others don't regulate it at all, so whether there's a state or local record of who's doing the install depends entirely on the address.
For an air conditioner install, the piece that's consistent no matter where the house sits is the permit. Replacing an air conditioner typically needs a permit from the local building office, and an inspector checks the finished work before it's signed off. That inspection is what stands behind the installation here, not a license, and it's worth knowing that's the protection this job comes with.

- What size air conditioner does my house need?
- The right size depends on your home's square footage, ceiling height, insulation, window placement, and how much shade it gets, so there's no number that applies to every house. Bigger isn't better here. An oversized unit cools the air fast but shuts off before it pulls the humidity out, so the house feels clammy even at the right temperature. A contractor will do a load calculation on your actual house, room by room, and size the equipment to that number.
- Should I replace the whole system or just the outdoor unit?
- In most cases you replace both together, not just the outdoor unit. The indoor coil and outdoor condenser are matched to work at a specific capacity and efficiency, and pairing an old coil with a new condenser usually means you lose the efficiency gains and put strain on the new equipment. If your indoor coil is old, a contractor may also flag the furnace or air handler it sits on, since a system installed years apart can end up mismatched in ways that shorten the life of the new outdoor unit.
- Do HVAC contractors in Kankakee need a state license to work on my home?
- Illinois doesn't license HVAC contractors at the state level for residential work. That's left to individual cities and towns, so whether a license is required depends on where in the Kankakee area you live. Check with your local city or village office to see what they require before hiring.
