i have a 2.5 ton miller airhandler with 10 kw. and a carrier 2 ton hp. installed carrier txv i had leftover. hp is not heating very well (cools great in summer) oh this is in a 70 * 14 moble home. it starts out cold for about 2 min then it starts putting out luke warm air. it will keep temps around what i want but i can not stand the cold air. (i like sitting over the vent with a cover). i charged it by subcooling and when its where it should be man it has pressures like 345-400. i know its over charged. my problem is my ductwork. i put my airhandler under the house. hard piped it with 14 round into the tralor duct. and i think that duct is leaking also. so im going to install new duct and make this right. my question is when i size the duct should i make it at a higher static (being a moble home) and would it be better too size for a 2 ton or a 2.5 (match my airhandler or the hp). seems like less airflow at a higher static would be better in my case.
thanks for any replys
