DeKalb County · ZIP 60178
Apex Climate Control has been inside Sycamore homes around one of Illinois' prettiest courthouse squares — and if there's one thing this town's housing teaches an HVAC company, it's not to assume anything until you've seen the mechanical room.
What we see here: a historic core of Victorian and early-1900s homes with steady modern growth at the edges — century-home retrofits remain a specialty need here. That range is exactly why we diagnose and quote from the actual house in front of us instead of a formula.
The climate does the rest. DeKalb County homes run furnaces near-continuously from Thanksgiving into March, then pivot to humid 90-degree cooling season — a duty cycle that finds every weak part and every dirty coil. Regular maintenance and clean airflow aren't luxuries here; they're how equipment survives.
Landmarks aside — and Sycamore has good ones, from the DeKalb County Courthouse to historic downtown Sycamore — what matters to us is the block-by-block reality of the homes. Our North Aurora shop is 25 miles away — close enough that Sycamore calls never sit at the bottom of a regional route list.
