    John H. Coleman Co. has a terrific staff of capable and kind people. I worked with Jason, Chris, and Brandon - who all helped me with decisions on direction, without trying to sell me anything.
    I hired them to replace two units for my building
    … More and also to install UV systems in each of our units. The install crew members were punctual, efficient, kind and knowledgeable.
    After spending time getting several quotes from companies around town, John H. Coleman came to me with the best price, best service, and a great follow through!

    Scheduled appointment and received reminder.
    Tech kept us informed on his ETA and arrived promptly. He was very courteous and thorough. He wore a mask the entire time.
    Coleman has been 5 star for us for the past 15 years.
