Hi, all,

Just spoke to a Trane contractor. He recommended replacing the entire
unit, inside and out, because both parts are 14 years old and because
we could increase the SEER to 15 if the parts were properly matched.
He also noted that our current air handler lacks a plenum for mixing
the cool air prior to sending it out into the duct!
He recommended the R22 system because 410 is still "beta" (not all the
bugs have been worked out yet).
Any thoughts?
