A system built for eight months of heat and three of cooling
Winter nights around Rockford average 16°F from December through February, and homes here need heat from October through May. That is 8 months of the burner or the heat pump running, against summer afternoons that average 82°F over just three months, June through August. Eleven months of the year, one system or the other is working.
Most homes here heat with gas, so the furnace carries the longer season. A new system has to be sized for those cold winter nights and still hold up through the summer afternoons, with both sides built to run this much of the year.

In Illinois, HVAC licensing for homes is left to the cities and towns.
Illinois has no state HVAC license. Whether a contractor here has been tested or registered at all depends on the city or township the house sits in, since some local governments set their own rules and others have none.
For this installation, the protection that applies is the permit process. In most cities and counties, replacing a furnace or air conditioner needs a permit from the local building office, and the work gets inspected once it is done. That inspection is what checks the gas connection and the rest of the work was done right, not a contractor license.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is old enough that a breakdown is a real risk, not a maybe. Needing repairs most years, rising energy bills, or a system that no longer keeps the house comfortable are all signs it is time. Here that decision matters more than in most places, since homes need heat or cooling from October through August, eleven months of the year, and a failure during a stretch of winter nights averaging 16°F is not something to wait out. If your furnace is old and due, replacing it before cold weather sets in rather than during it is worth planning for.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, and there is a real reason for it here. A furnace and air conditioner installed together are matched to work as a pair, and replacing one while keeping an old one often means the new equipment cannot run at its full efficiency. With 83.5% of homes here heating with gas, most furnaces and coils were sized and installed together in the first place. If only one is failing and the other is still young, a contractor can tell you whether replacing just the one makes sense for your system.
- What happens during an HVAC installation?
- The contractor removes the old furnace, air conditioner, or both, and sets the new equipment in place, then connects it to your ductwork, gas line or electrical circuit, and the condensate drain. For a furnace, that includes venting for exhaust and testing the ignition and gas pressure. For an air conditioner, it includes running refrigerant line to the outdoor unit and charging it to the right level. Once everything is connected, the contractor runs the system through a full cycle to check airflow, temperature rise, and that it shuts off and restarts the way it should.
