The salesman, Rob, was very knowledgeable about the options for our HVAC. He was very detailed, clear and concise with his approach. He helped us to find the exact heating solution for our home. The price was actually lower and for a better system than the other quotes we got. The install crew was very good. They were professional, did quality work, and left no mess in our home. I would definitely recommend Hamilton Heating and Cooling.
