What Pekin winters and summers ask of a new system
Pekin sees eight months of heating and four months of cooling, and with winter nights averaging 20°F from December through February, a new furnace has to be sized to handle real cold, not mild chill. Most homes here already heat with gas, so that furnace runs hard for most of the year. Summer afternoons average 84°F, so the air conditioner paired with it has its own season to answer for, shorter but still real.
Tazewell County has logged 10 winter storms and 154 damaging wind events over the past ten years, and across Illinois 16% of households lost power for at least a day in 2024. A new system installed here should be matched to both seasons and set up so it comes back on its own once the power does.

In Illinois, HVAC licensing for homes is left to the cities and towns.
Illinois does not test or license HVAC contractors at the state level. Whatever rule applies depends on the city or town the house is in, since licensing here is a local matter and not a state one.
For an installation like this, the protection that matters is the permit. In most cities and counties, putting in a new furnace, air conditioner or heat pump needs a permit from the local building office, with an inspection once the work is done. That inspection is what checks the job was done right, since a bad gas or electrical connection is the part of an installation that can actually hurt someone.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is old enough that a repair bill makes you stop and think about the cost of a new unit instead, that is the sign. Failures tend to come more often and cost more each time once a system gets old. Your furnace runs here from October through May, so if it quits on a cold night you are not left waiting long for a fix. If yours is getting up there in age, it is worth having a contractor look at it before the next cold stretch rather than after it fails.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, that is usually the better time to do it. A furnace and air conditioner installed together are matched to work with each other, and a contractor can handle the ductwork and wiring for both in one job. If one is much newer than the other, replacing just the failing one is the more sensible call. A contractor can look at the age and condition of both and tell you which situation you are in.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or air conditioner in place, and connects it to your ductwork, gas line or refrigerant lines, and electrical. Once it's connected, they check the airflow, the refrigerant charge if it's an air conditioner, and the gas pressure and ignition if it's a furnace, making sure everything runs the way it should before they leave. They will also check that the system is sized right for your house. The exact steps depend on what you're replacing and how your current setup is laid out, so a contractor can walk you through what it means for your house specifically.
