Everyone I interacted with was so professional: respectful, showed up on time, left everything clean, good communication. Price on installing. a zone heating system was much more reasonable than the other quote we got. On top of that, Dante, who came to take care of changing out a filter part that had been installed incorrectly by another firm, went the extra mile to troubleshoot a solution to the cause of the problem and suggest alternatives. THEN when he heard how loud the heater was, tuned something so that now it's WAY quieter.
