Excellent. Paul is a very comfortable and professional person to talk to. I received five estimates to replace my system. Two were high. One was low. Then Paul and one other installer came in very close together. Paul was slightly more expensive than the other HVAC Company. But the rep from the other company missed our first appointment and was late for the second appointment. Paul gave us a very good presentation on what to expect. He told us the different systems, and suggested that for us a least expensive system was actually the better choice. The install team showed up on time and took great care during the install. Very happy overall.
