Hassler Heating is a terrific company! Their skills, professionalism, teamwork, and efficiency exceeded anything I could have imagined. Everyone I met was skilled, pleasant, competent and really committed to doing a great job.  I am so happy with our new furnace and duct work and our new tankless water heater. They started and ended with an energy audit and assisted with obtained rebates and coordinated everything from start to finish. This is a 10 star company and I highly recommend them!
