Westenn Heating & Air Conditioning

Mission: To provide all of our customers with exceptional value through professional workmanship and integrity.

For over 50 years, Westenn has been a leading provider of HVAC installation and service for commercial and residential customers in Walworth County and the surrounding area. Westenn’s quest for 100% customer satisfaction is reinforced every single day. Moreover, Westenn is renowned for its quality technicians who have all undergone, and continue to receive, the most up-to-date product and installation training.

Ray Alberth and Randy Smith purchased Westenn on January 1, 2020. Under Ray’s leadership, and tapping into his industry expertise, Westenn is poised to grow its customer base with uncompromised quality, value and honest service.

“For me, taking over the operations of Westenn is a dream come true,” says Ray Alberth. “The opportunity brings me back full circle to where I began my HVAC career as one of Bill’s employees over 25 years ago. Randy and I are excited to continue offering the full range of heating, cooling and air quality services and products.”

Professional. Honest. Value.

Three little words that are taken to heart and form the foundation of Westenn.


“I had Ray install a whole new furnace a/c and all new duct work in my remodel project. His craftsmanship was superb and his price was very reasonable! I watched him build a custom duct for the project in the field that looked like it was built in the shop. I will definitely use him and Westenn on my next project. I highly recommend Ray and the Westenn company. ”

Tommy G • Remodel Design and Install

“The technician you sent was outstanding! I don’t think I’d rate any other HVAC tech higher that I’ve ever used – sharp – quickly diagnosed the issue and fixed it.”

Mike C • Residential Repair
