Our Story

Denny Sisler

Denny Sisler, the owner of Sisler Heating & Cooling, Inc., began working at a young age for Ty’s Heating & Cooling in Valley City, Ohio. Soon after, he realized that the heating and cooling field was something that could always be needed and decided to start his own company in 1979. He started with a two man operation and did heating and cooling in many new construction homes throughout Medina County. His business thrived well enough that in 1994 he was actually able to purchase Ty’s Heating and Cooling. Since then Sisler Heating & Cooling, Inc. has become one of the most well-known heating and cooling companies in northeast Ohio.


We believe that our job is not only to install HVAC systems that function to their greatest ability, but also that every job should be done as if it was in our own homes. We have received numerous awards for our work & lots of customer referrals.
