Hello everyone, I have a 2 story home with a basement approx 3/4
finished. Each level is approx 1500 sq ft. My hvac unit is a Trane XV
80 ( gas ) that was installed about 5 yrs ago by the previuos owners.
The house is about 15 yrs old so I dont think the insulation is all
that bad. My problem is that about 30% of the first floor which is the
family/tv room has a vaulted ceiling and the master bedroom on the 2nd
floor sits directly above a 2 car garage. I am going to assume ( yes I
do know the ass out of you and me saying ) that the unit that was
installed is sufficent. I did do some homework and found that the 2nd
stage wasnt even hooked up, not even a jumper, so I jumped the
terminals and the 2nd stage comes on after a delay of about 10 min.
There was a big difference in the fan speed and made somewhat of a
difference. It still gets extremely cold in the master bedroom, I guess

from the garage ( We live in NJ so it can get pretty cold ). I had
installed an R-30 in the attic on top of the existing R-19, so the
combination of the two should be good. I am also going to remove the
ceiling in the garage and do the same (this should help with the
bedroom), and go for 2 new and well insulated garage doors. Would it be

worth putting the 1st and 2nd floors on two zones.With the heating
prices rising, I am not all that that comfortable for the price we are
paying, wouldnt be so bad if we were comfortable. We keep all the vents

in the basement closed because that space is rarely used. I have all
the access to both main feeds in the unfinished portion in the basement

and I can "do it myself", also would wrapping the ductwork also be
worth it. Sorry for the long story, but I wanted you to have all the
information to base your answer. Thanks for any info on this subject
