Customer Testimonials
"The first contractor we used to install our hybrid system didn't do the job right, and we didn't even realize our heat pump wasn't heating for a couple years. Only the furnace was heating and propane is expensive. Now we have the right thermostat, and are system is working correctly. We highly recommend JD Marx." - K. Boudreau
