The stock heater/blower should provide plenty of heat and air if the system is clean of mouse nests and debris, and the diverter doors and fan are working properly.

On the right side of the interior heater box there is a rectangular plastic plug where one of the cables goes through. Pull that plug out and with a good light you can see if there is a mouse nest in the outside heater box through the hole.
