JC Heating and Cooling serves homeowners and businesses throughout Rock County and surrounding Southern Wisconsin communities. From our shop at 300 South River Street in Janesville, we're close enough to respond quickly across our entire service area — whether it's a furnace that quit in the middle of January or an AC that decided summer was the perfect time to act up.

Janesville, WI — Our Home Base Since 1997

Janesville is where we work, where we live, and where we've been building our reputation one customer at a time since Jason Cox founded this company nearly 30 years ago. With over 66,000 residents, Janesville is the county seat of Rock County and one of the ten most populous cities in Wisconsin. It's a community of established neighborhoods, growing subdivisions, and a mix of older homes and new construction — and every one of those homes needs a reliable HVAC partner.

The median construction year for Janesville homes is 1972, which means a significant portion of the housing stock is aging into the sweet spot for equipment replacement and efficiency upgrades. Whether your furnace is original to the house or you're looking at your first heat pump, we've seen it all right here in our own backyard. We serve all Janesville zip codes — 53545, 53546, and 53563 — for heating, cooling, air quality, and everything in between.

Beloit, WI — Rock County's Second-Largest City

Beloit sits about 12 miles south of Janesville and is a community we know well. With a population of over 36,000 and a dense mix of residential neighborhoods and commercial properties, Beloit keeps our team busy year-round. Manufacturing is the city's largest employment sector, and we're proud to serve both the families who live here and the businesses that keep Beloit running.

Beloit's housing stock skews older, which means furnace replacements, ductwork repairs, and AC upgrades are common calls we get from this area. We handle it all — furnace repair, central air installation, heat pump systems, ductless mini splits, and seasonal tune-ups for both residential and light commercial customers.

Milton, WI — History in Progress

Milton is increasingly tied to Janesville, its larger neighbor to the south, with parts of Janesville now falling within the Milton School District as the city expands northward. It's a growing community with a proud history — the Milton House, built in 1844, is a National Historic Landmark and one of 14 recognized stations on the Underground Railroad, making it the oldest concrete building still standing in the United States.

The median home value in Milton has more than doubled since 2000, reflecting real growth in this community. New construction and established neighborhoods sit side by side here, which means we're just as likely to be commissioning a brand-new Daikin system in a new build as we are replacing a 20-year-old furnace in an older home. We serve Milton for AC installation, furnace replacement, heat pumps, and seasonal maintenance.

Edgerton, WI — Tobacco City, U.S.A.

Edgerton earned the nickname "Tobacco City U.S.A." for its role as a historic center of the tobacco-growing industry in southern Wisconsin, and it still carries that small-town character today. With a population near 6,000 and a footprint that spans both Rock and Dane counties, Edgerton is a tight-knit community of homes, farms, and small businesses that we're glad to call part of our service area.

Older homes are common in Edgerton, and we see a lot of systems that are overdue for an efficiency upgrade. If your heating bills have been creeping up or your AC is struggling through summer, give us a call. We handle HVAC repair, installation, and full system replacements for Edgerton homes and small businesses.

Evansville, WI — A Town Worth Knowing

Evansville sits about 20 miles northwest of Janesville and is part of the Janesville–Beloit metropolitan area. It's the kind of place that surprises people — the Wisconsin Historical Society called Evansville home to "the finest collection of 1840s to 1915 architecture of any small town in Wisconsin." All those beautiful older homes? They need good HVAC care.

Over a third of Evansville's housing units were built before 1940, which means aging boiler systems, undersized ductwork, and equipment that's well past its prime are common situations we walk into here. We're experienced with older homes and can help you figure out the right upgrade path — whether that's a modern boiler, a ductless mini split, a heat pump, or a traditional forced-air replacement. We serve Evansville residential customers for heating, cooling, and everything in between.

Whitewater, WI — Furnace repair, AC service, and HVAC installation for Whitewater homeowners and businesses.

Whitewater, WI — College Town, Real Homeowners

Whitewater is home to the University of Wisconsin–Whitewater and is located near the southern portion of the Kettle Moraine State Forest. With a population of over 16,000, it's a lively community that sometimes gets reduced to "the college town" — but there are real homeowners, landlords, and business owners here who need dependable HVAC service, not just a quick seasonal call.

We serve the non-student side of Whitewater for furnace repair, AC service, HVAC installation, and ongoing maintenance. Whether you own a home, a rental property near campus, or a commercial building in town, JC Heating and Cooling is close enough to get there fast and local enough to care about the work we leave behind.

Janesville, WI — Our home base since 1997. We serve Janesville homeowners and businesses for all heating, cooling, and IAQ needs.

Beloit, WI — We regularly serve Beloit residential and commercial customers, including furnace repair, AC service, and HVAC installation.

Rock County and Beyond

We serve communities throughout Rock County, Wisconsin — including Clinton, Orfordville, Brodhead, Fulton, and the townships in between. Southern Wisconsin's climate is no joke: winters regularly push below zero and summers get genuinely humid. Your HVAC system works hard here, and it deserves a team that knows the region.

If you're not sure whether we cover your area, just call us at (608) 752-2472. We'd rather answer that question than have you go without heat waiting to find out. Financing is available through Wisetack, and we're a proud authorized Daikin Comfort Pro dealer — which means factory-trained technicians and equipment backed by some of the best warranties in the industry.
