We recently decided to replace our 20 year old furnace with a new one and add air conditioning. These guys were great through the whole process. The estimate was thorough and detailed. They went over what we wanted out of our system, and explained how each of several potential options compared to each other to meet our needs. Very knowledgeable about their product and the industry as a whole. The person who we dealt with was very nice about making sure we were aware of, and offered, any and all options, but I never felt like he was selling me. I always felt like he was offering options just in case one of them was something I really wanted. He even pointed out, several times, things that were options but he suggested not doing them because the cost to benefit was low. Install was a big job because my garage has fairly low ceilings and the furnace is buried in a corner by the water heater. But they got the whole thing torn out. New furnace installed and new A/C installed in one day!
