About Harker Heating & Cooling

COVID-19 Specific Information and Services

Madison’s Honest HVAC Company

Together with our team members, HVAC technicians and manufacturer partners, we’ve been able to sustain a company that puts its Midwestern values up front and center. When you’re in need of HVAC repairs or replacement, you can bet on receiving an honest estimate and a firm handshake to demonstrate our commitment to serving you.

Not sure of your home heating and cooling options? We invite you to visit our premier showroom at 87 West Beltline Highway in Madison, where one of our Harker HVAC specialists can show you our wide array of furnaces, air conditioners, water heaters, and radiant heat options. In need of a fireplace instead? We’ve got those, too.

Harker is open for business. We will be taking extra precautions to ensure we keep all of our staff, including office and technicians, healthy and safe through these challenging times. Your health is very important to us also. Please don’t hesitate to call us if you have any questions! If you need to stop by and grab a filter or a part – call ahead at 608 480 6157. We can deliver it to you “curbside.” 🙂
