Top Notch Customer Service. They responded to my service call way faster than I expected (I called around 6:30 in the morning and they were there by 8:30 when I’d been told the backlog for the day would likely mean not seeing them before noon). The two technicians were courteous, friendly, and professional in their demeanor. They did end up making an incorrect diagnosis of what was wrong with my heating but their customer service gave me a full refund for the call, again handling what could have been a negative exchange into one where I’d be willing to call them again if I have another major issue with my HVAC or plumbing. No gimmicks, no excuses, they put the customer first.
