been sorting out my choices for a new system and have learned a bunch from all of your responses to my posts and by reading the posts of others. i am extremely grateful to all of you who take the time to educate us.
here is what i believe i want but not sure what else pieces go with it (so i can bounce it off what the contractor will be proposing)
auxil heat strips
clean effect air filter
if it make any difference, my system is in a attic in a horizontal layout, i am in the nothern virginia area, and 3 1/2 ton unit.
is there a guide to perfectly matching a system (i.e. what pieces work best with each other) that is available to homeowners?
