Responded to a no-heat call for the furnace in the wine storage cellar. Upon inspection, found the inducer motor to be seized. Examined the heat exchanger and noted the furnace is in very poor condition—originally installed in 1999. Unable to perform a combustion analysis until the inducer motor is replaced and a major cleaning is completed. Also observed rodent damage within the furnace. While inspecting the heat exchanger with a scope, no visible cracks were found. However, we cannot guarantee it is not compromised without a combustion analysis, which cannot be performed until the inducer motor is installed. Given the age and condition of the unit, repairs are not recommended. Estimates have been provided for a new furnace installation, which will include a warranty. Please reach out to Richard regarding the new furnace installation.
