Robert and John Freund founded Comfort- Air Engineering and Primo Plumbing, Inc in 1964. Both are mechanical engineers from UT. They wanted to design and build air conditioning systems for residential and commercial customers who lacked indoor cooling. The second generation took over the family business in 2001, and we continue to design and build mechanical systems, and serve our community for all of their HVAC and plumbing needs in residential, commercial, and industrial spaces.
