“After 15+ years, we decided it might be a good idea to replace our heating and cooling unit. We were scheduled with Big John. He is a very personable and professional salesman. He presented us with 3 quotes and was very through in explaining all of the differences. We just had our final walk through and Big John helped me get the app and set up our new thermostat and gave me great tips. I highly recommend scheduling with Big John and Hamstra.”
