Heating & Cooling



A. N. Roth Company is a fifth-generation, family-owned heating, air conditioning, geothermal, and injection foam insulation company that services Louisville, Southern Indiana and the surrounding areas. We opened our doors in 1866, the same year Congress approved the creation of the nickel. Coincidentally, our ‘whole house approach’ and fair prices have helped our customers lower their energy use and save those nickels – a lot of them.

We are Louisville and Southern Indiana’s home comfort and energy experts, having earned a reputation for doing things right the first time. Some of your neighbors, your favorite restaurants and professional contractors call A. N. Roth Company to solve indoor air quality and comfort issues in homes and commercial buildings. Our decades of expertise and inventory of tools enable us to develop customized solutions for nearly any heating and cooling problem. Call or email us right now and find out why we are Louisville and Southern Indiana’s home comfort and energy experts.
