return duct size
I'm getting my heat exchanger replaced through my home warranty and they approved the repair however the repair company wont do the repair until I agree to a suggested repair to my return duct. I have asked why and they say because its a 10" return and should be 12". The house currently has two returns one 20 x 20 and one 14 x 20 for a 3 ton unit. Is this suggested repair needed?
