Thanks for the recommendation of the chart.
It is hard for me to trust HVAC people on such matters. Last year my
parents got new units for two houses. One has two stories, six
bedrooms, 5.5 baths, and seven other rooms and they sized it at 2
tons. Now the inside of their house is mildewing because it can't
keep it cool or dry. The other house is one small story, three
bedrooms, two baths, 2 other rooms, and they (different person) sized
it at 4 tons. I told my parents that, if anything, they should have
put the 4 ton unit in the big house and the 2 ton unit in the small
house.

All you need to do is hang around here for a while (or, better still,
alt.hvac) to know that there are plenty of alleged "professionals" in
the business who don't know squat.

They first should have gotten a heat load on both homes to show them what
proper size was needed.

Hi,
If that pump has been running well, it has few more years life left.
B4 you decide to spend for upgrading, how about air
tightness(insulation) of your house? SEER 10.5 is of course outdated to
today's standard but to get real improvement you have to deal with whole
package, not only one component of a system.(like air handler, etc.)
What is your electric rate? I pay 7 cents/KWh.
