Heat Pump Return Duct

12 years ago

I have a 4 ton heat pump(Goodman #GPH1348H12A) set up in a 24x56 (1344 SQ FT) mobile home. I have two 16" return ducts that tie into one main 16" return line to the unit (Flex hose). The Filter size at each is 14x20x1. I have two 14" (Flex) lines that tie into each side of the mobile home's rigid ducts (One single long line). I have had a problem needing to charge the A/C each summer and a tech has told me it is due to the main return line needing to be 20" with both 16"s joining to it. Also the vents need to be 20x20x1. Are the 16" returns okay or do I need to plan a replacement project?

Good grief the FIRST and only thing you need to be concerned with ( yes I know this is a old thread/posts but I have to respond to this ) is what in the world is a 4 ton doing in a 1300 sq ft double wide???????????? If you dont have moisture problems your house must be blessed by god himself. That unit is ENTIRELY too large for your home.
