We purchased this Bosch System because of its rating and efficiency. Our old system was no longer efficient so we decided to spend more money than we had originally planned to get a top of the line system. The installation went great, the installers were very knowledgeable at what they were going. We only hope the system lives up to its reputation and performs as the comfort representative said it would. As far as pricing we don't know because we never compared with any other companies. Only problem right now is getting adjusted to the new thermostat and how it works. Thanks You Dave and Debbie Strothers
