On a service call to check out a newer 125,000 BTU 90+ furnace. It is running a supply temperature of 146 degrees and the blower is on medium high speed. The homeowner is complaining that the fan noise is bothering them. The furnace seems somewhat oversized and is short cycling when on. Is there any reason why we shouldn't plug one or more of the burners, reducing capacity to 100K or less, and then reduce fan speed to get nameplate temperature rise?
