Customer feedback reveals two named technicians making notable impressions. John Anderson received praise for replacing a furnace within five days during winter conditions, navigating shipping delays and adverse road conditions to restore heating after a carbon monoxide inspection flagged the old unit. Another reviewer mentioned John's work from eighteen years prior, original ductwork designed for future expansion that earned compliments from a subsequent contractor during a system upgrade. However, one customer reported unresponsive service calls regarding a refrigerant leak, noting persistent voicemail issues reaching their service department.
