Learn More About Bob's Quality Heating & Air Conditioning

The dream of owning a business became a reality in 1978 when Bob and Mary Nennig started Bob's Quality Heating & Air Conditioning in their garage with the help of their 3 children. In 1985, Bob's Quality Heating & Air Conditioning moved to our current location at 123 S Railroad St in Kimberly.

In 1997, Todd and Kim, Bob and Mary's son and daughter-in-law, bought the business. Today, they operate the state-of-the-art facility with 18 employees, 12 service vehicles, and the same commitment to quality and values that our founders had.
