HVAC Services in Bayside, WI

North Shore Heating and Cooling, On Your Schedule

Bayside sits at the top of Milwaukee's North Shore, and its homes — many from the postwar decades, shaded by mature trees near the lake bluff — are now on their second or third generation of mechanical systems. When one of them quits, On Time Heating & Cooling answers 24/7 at (262) 671-8999.

We are a family-owned Waukesha company: owner Shane Herro founded On Time in 2019, still works service calls, and trains every tech on the crew. That approach has earned a 5.0★ rating across 480+ Google reviews and the Best of Waukesha 2025 award.

Established Homes, Layered Systems

Decades of renovations leave North Shore houses with mixed-era ductwork, additions on their own heat sources, and cooling that was squeezed in after the fact. We diagnose the system you actually have, test airflow instead of guessing, and design replacements around a real load calculation — because an oversized unit short-cycles and dehumidifies poorly in lake-adjacent summer air.
