History

Alfred Lassen opened the doors of Lassen Heating & Air Conditioning, Inc. in 1982 to serve the needs of Connecticut's Northwest communities by installing and repairing heating and air conditioning systems. Over the years, we have grown to become a trusted HVAC services company offering a wide variety of name brand products and highly skilled services for heating, cooling, comfort and safety across the North and Northwest Suburban area.

Now under ownership of Alfred's son, Sean Lassen and his team remain focused on the customer by providing them with superior design, installation and service capabilities.
