Flock's Heating & Air Conditioning

Our roots go back to 1960, when Clarence Flock founded Flock’s Sheet Metal near Cashton, Wisconsin. Sylvester and Ramona Flock purchased the operation in 1970, followed by their sons Mark and Anthony “Tony” Flock in 1985. Their brother William “Bill” Flock joined them as a partner in 1998. In 2002, we became Flock’s Heating & Air Conditioning to better reflect the work we do. More than 55 years after our founding, we remain family owned and operated, serving homes and businesses throughout west central Wisconsin.

We design, install, maintain, and repair a broad range of heating, cooling, and indoor air quality systems. Our services include central air conditioning, high-efficiency oil and gas heating, geothermal ground-source heating and cooling, programmable thermostats, whole-house humidifiers and dehumidifiers, air exchangers, garage heaters, air filtration systems, and custom sheet metal work. We also provide system tune-ups and cleaning, safety and efficiency agreements, free estimates, and 24-hour emergency service. Whether a customer needs help with a home comfort system or commercial HVAC equipment, we work to find an option suited to the property and its needs.

Geothermal heating and cooling has become an important part of our work. We were named ClimateMaster’s Wisconsin Geothermal Contractor of the Year in 2008, and Mark Flock was elected president of the Wisconsin Geothermal Association in 2013. We have also partnered with WaterFurnace International to provide geothermal systems for heating, cooling, and hot water applications. From geothermal equipment to traditional oil and gas systems, our trained, licensed, and NATE-certified team serves customers in Cashton, Sparta, Tomah, and the greater west central Wisconsin area. Our mission remains simple: to treat our customers as we would want to be treated while providing quality heating and cooling service at the best prices possible.
