The repairman came and was super nice, and honest. Did not try to sell anything extra. We decided it was better to replace whole furnace instead of repair. Today it was installed, so I cannot rate unit, though it’s quiet and works. I can rate the guys and installation. Everyone was awesome, from delivery to tear out, to installation. Polite respectful and honest. Cannot say enough good things about Best Service. I am completely satisfied and happy. Thank you!
