Heat that keeps up with Rockford winters.

Rockford winter design temperatures fall to -7°F to -10°F, followed by humid 90°F summers. Older homes along the Rock River have deep basements, and most east-side homes use basement gas furnaces.

## Climate

Rockford sits at the northern edge of IECC Climate Zone 5A bordering Zone 6A. Winter design temperatures fall to -7°F to -10°F with heavy snow and freezing winds across the northern prairie, while July and August bring humid heatwaves fueled by Midwest agricultural transpiration ('corn sweat').

## Local homes

Neighborhoods along the Rock River—Edgewater, Churchill's Grove, and Rural Oaks—feature early-20th-century foursquares, Tudors, and bungalows with deep stone or poured-concrete basements. East-side Rockford, Loves Park, Machesney Park, Cherry Valley, and Roscoe/Rockton feature 1950s–1990s ranches, tri-levels, and two-story homes with basement gas furnaces and split-system central AC.

## Utilities

Commonwealth Edison (ComEd) for electricity and Nicor Gas for natural gas. Both ComEd and Nicor Gas offer residential rebates for upgrading to qualifying furnaces, air conditioners, cold-climate heat pumps, and smart thermostats.

## Questions

### Can my chimney-vented furnace in an older Rockford home be upgraded to a 96% high-efficiency furnace?

Yes. Older 80% furnaces in Edgewater or Churchill's Grove often vent into a masonry chimney alongside the gas water heater. When upgrading to a 96% condensing furnace (which vents horizontally through PVC pipe), licensed partner crews check that the remaining water heater flue is properly sized or lined per code.

### Do ComEd and Nicor Gas rebates apply in Rockford, Loves Park, and Roscoe?

Yes. Because Winnebago and Boone counties are served by ComEd and Nicor Gas, homeowners replacing a furnace and AC with qualifying equipment can take advantage of both utilities' rebate programs.

### How does financing work if my furnace fails in the middle of a Rockford winter?

No one plans for a cracked heat exchanger in January. Your advisor puts your system price in writing alongside financing options, so you can decide and get a licensed local crew scheduled.
