A.N. Roth Company is a fifth-generation, family-owned heating, air conditioning, and geothermal 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. A.N. Roth Company was a finalist for the 2020 Greater Louisville Inc. Inc.redible Award for Small Business, and the Small Business of the Year award winner of the Family Business Award facilitated by Louisville Business First and the University of Louisville Family Business Center.
