Our History

Bay Heating & Air Conditioning is a third-generation, family-owned business.

The first generation, Bill Patterson, started the business in Bay Village in 1944, with Al Tresch joining as his manager in the 1960s. The second generation, Bill’s daughter and son-in-law, Lynn and Billie Robinson, joined the business 35 years ago. They were also joined by Al Tresch’s son, Roger J. Tresch, Sr. The third generation, Roger J. Tresch, Jr., joined Bay Heating & Air Conditioning in 1994, and Billie and Lynn’s daughter, Kori Robinson, joined in 2000.

Since Bay Heating & Air Conditioning’s humble beginning, we have made several moves before finally settling at our present Westlake location in 1970. Our motto is: “If you don’t sacrifice your comfort, we won’t!”

    "Cleaned up the work area as if they were never there"
    Bay furnace installed a whole house humidifier in March. The crew was very polite, professional and cleaned up the work area as if they were never there. I definitely would recommend them.

    "Our basement was cleaner than when they arrived"
    Yesterday we had our furnace replaced. The service people were warm and friendly. They explained everything to us. They explained the thermostat until I understood It. They cleaned up so much that our basement was cleaner than when they arrived. I highly recommend them.

    "Our new A/C is awesome"
    Excellent service. Installers were very friendly and knowledgeable. Our new A/C is awesome. Thanks Bay Heating and Cooling.
    - Brian S.
    "This kind of workmanship is hard to find these days"
    I'm very happy with the furnace/AC replacement project carried out by Paul, Johnny and Jerry. Top rated! This kind of workmanship is hard to find these days. It comes down to the people who put the system in the house. We pay a little more but we got a team who stayed with Bay furnace for 20+ years, who took pride in their finished product.
    - Zhiqiang G.
