Our service tech Ian was courteous, friendly, knowledgeable, and competent. He thoroughly inspected the furnace and found one faulty component that was replaced on the spot under warranty. He went above and beyond by offering to replace the humidifier canister that was due soon, saving us another service call that we had planned next month. Kept us informed at every step, and left us very satisfied with the service. We're glad that we have the service plan with Comfort Matters.
