Heating and Cooling Service in the Village of Thiensville

Thiensville may be the square mile Ozaukee County village surrounded by Mequon, but its homes face the same Wisconsin extremes as everywhere else we work — and when a system fails, response time is what matters. On Time Heating & Cooling runs a genuine 24/7 line at (262) 671-8999; a person answers, and a tech gets moving.

We are a family-owned Waukesha operation, founded by Shane Herro in 2019. Shane is still in the field, the techs are factory-trained, and the results show: a 5.0★ Google rating across 480+ reviews and the Best of Waukesha 2025 award.

Everything Your Thiensville Home's Comfort Runs On

• Furnaces — repair, replacement, seasonal tune-ups
• Air conditioning — repair, installs, maintenance
• Boilers — common in the village's older housing stock, and a specialty of ours
• Heat pumps and ductless mini-splits
• Water heaters and tankless systems
• Indoor air quality and air duct cleaning

Older Villages Deserve Careful Work

Established village blocks mean mature trees, tighter mechanical rooms, and heating systems that have been renovated in layers over decades. We diagnose what is actually there before recommending anything, pressure-test airflow rather than assuming, and quote repair and replacement honestly so you can pick the path that fits.
