A.N. Roth Company is a fifth-generation, family-owned heating & air conditioning, geothermal, and radiant flooring heating company that services Louisville, Kentucky, 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 commitment to fair prices have helped our customers lower their energy use and save those nickels – a whole lot of them.
