Gregg Heating was established by Greg Hausinger in 1974, with a 1968 Ford station wagon, since then it has grown to a million dollar + company. Greg learned the heating and air conditioning trade from an old German craftman, who said, "Do the job right the first time, and stand behind what you do." That has been our motto, for the past 38 years.
