Doug with LHI Litchfield Heating Inc. has been doing my make-up air and air turnover start-ups for over 25 years. I don’t believe there is a more qualified service technician to work on any large commercial/industrial unit than Doug. He is my first and only call when I need an expert with start up experience in the industrial HVAC field. He is honest, easy to work with, and can troubleshoot and correct any issues that arise.

His quality of work has always met my and exceeded my expectations. After 25 years of working together, I also consider him a great friend.
