Tezel & Cotter Air Conditioning, L.P.

Mr. William E. Ebert, a mechanical engineer from New York, founded Ebert Air Conditioning, the parent company of Tezel & Cotter. This was the first company in the area to concentrate its efforts in the “new field” of air conditioning. Mr. Ebert passed away in 1948, and the company was purchased by Otto E. Tezel, his Plumbing Foreman and by Mr. R.P. Cotter, a local Mechanical Engineer. At that time the company was renamed Tezel and Cotter Air Conditioning Co. and it continued to grow in the installation and servicing of heating and air conditioning systems. In 1964, Paul Tezel joined the company as service manager and in 1968 R.J. Cotter joined the company in the construction department. In 1995, Paul Tezel purchased R.J. Cotter’s outstanding shares and appointed Stephen Tezel Vice President in charge of construction and John Tezel Vice President in charge of Business Operations.
