Four months of real heat, every year
Peoria County runs its air conditioners June through September, with summer afternoons averaging 84°F. That is not extreme heat, but it is steady, and a new system needs to hold up to four straight months of daily work without a break.
The county has also logged 106 hail events and 147 damaging wind events over the past ten years, with hail up to 2.5 inches. The outdoor unit sits exposed to that. Any new air conditioner installed here has to meet the federal efficiency minimum of 13.4 SEER2, and it needs to be set up and protected with those storms in mind.

In Illinois, HVAC licensing for homes is left to the cities and towns.
Peoria County does not run its own contractor license, and Illinois has none either. Whether any local rule applies depends on Peoria itself or whichever town the house sits in. There is no state list of tested contractors here. That part is left entirely to the local building office.
For an air conditioner install, the piece that does show up here is the permit. Most cities and counties require one for a new air conditioner, and an inspector checks the finished work once it is done. That inspection is where the wiring and the unit's placement get looked at by someone outside the company doing the job.

- What size air conditioner does my house need?
- There is no single size that fits every house. The right size depends on your square footage, how many windows you have and where they face, your insulation, your ceiling height, and how many people live there. Too big and it cools the air fast but never runs long enough to pull the humidity out, so the house feels damp and cool at once. Too small and it runs constantly through the summer and still struggles to catch up on the hottest afternoons. A contractor works this out with a load calculation on your actual house, not a formula based on square footage alone.
- Should I replace the whole system or just the outdoor unit?
- In most cases the outdoor unit and the indoor coil need to be matched, so swapping only the condenser can leave you with a system that runs poorly or wears out early. The two parts are engineered to work together at a specific capacity and refrigerant charge. If your indoor coil is old too, replacing just the outside unit often means replacing it again in a few years anyway. A contractor can look at the age and condition of your indoor coil and tell you whether it can pair with new outdoor equipment or whether it makes more sense to do both at once.
- Do HVAC contractors in Peoria need a state license to work on my home?
- Illinois does not license HVAC contractors at the state level for residential work. That is handled city by city, so whether a license is required depends on where you live. Check with your city to see what it requires before you hire someone.
