    Debbie

  • Your gentlemen successfully identified some faulty parts causing our never ending heating struggles.   We really appreciate what they are doing for us. 

    Andy

  • Thank you for the great service.  Greatly appreciated. 

    Don

  • Thank you for the professional installation of the garage heater.  It looks great and so far is doing the job.  Not that I wish for colder weather, but I can’t wait to see how warm the garage is when it’s -20 outside.  This will be a game changer this winter.  No more warming up the car before leaving for work.

  • Just a little “thank you” for your time and patience with us during our “building” issues.  We really appreciated Tim & Jesse coming out and talking us through the heating options.
