Cased Coil Misalignment

On occasion, you will either find a furnace or be tasked with installing a furnace where the coil overlaps the edge of the furnace because the coil is wider. In the case of a Carrier CNPVP coil, you need to ensure that you align the coil according to the manufacturer's specs, or you risk cutting off about 1/3 of the airflow.

The best-case scenario is to use a coil that is a sizer match for the coil, or you can buy or make a tapered metal transition between the furnace and the coil. In the case of the CNPVP, the manufacturer allows the coil to be offset to the left.

In this video, we illustrate replacing a leaking coil and reconfiguring it in the proper orientation.
