In November of 2014, our furnace failed unexpectedly when it began leaking carbon monoxide into our basement. Representatives from Komfort Heating & Cooling quickly arrived at our residence to assess the problem. They were able to identify the cause as a failed heat exchanger, and gave me the option of repairing the existing unit, or replace the furnace with a new unit. I opted for a new furnace, which arrived with the installation technician within two hours. The technician was very meticulous, knowledgeable, and courteous. His pride in workmanship was evident as he explained the installation procedure, and his knowledge of applicable codes was equally impressive. The new furnace was started up and thoroughly checked out for proper operation. The old furnace was removed and everything was cleaned up nicely. I highly recommend Komfort Heating & Cooling.
