    A few years ago Paul Johnson Installed my Fujitsu Air/Heating unit in our masterbedroom by his suggestion. The unit is fantastic and is also an air filter unit as well. The installation went really well and I couldnt have been happier.
    Since it's installation Paul has conducted an annual cleaning/ inspection of the unit. He is the owner and service provider and just a great and honest guy. I look forward to his annual visit and highly recommend his services and products.

    i had a nightmare situation with a company called TL Services. I called Paul, he came out and with in a few minutes found the issue. it was a $10.00 breaker, not a $325.00 repair that TL Services quoted. This is the company to go with.

    I don't like strangers coming to my house! I took the recommendation of a friend to speak with Johnson Air when looking to install an air conditioning system (It was HOT this year). Paul Johnson came out and I could not have been more pleased with the results. Pleasant, honest, and a clean cut Marine who owns Johnson Air.. Nice air conditioning system is now awaiting the summer!
