Since he didn't respond to my prior post & doesn't listen to advice, I
figure he will end up screwing up big-time!
Houston,TX, huh. Summer Design is 95-Dry Bulb. 77-Wet Bulb or 18 degree
drop, around 44% Relative Humidity.
I thought there should be a higher humidity down there, - Stated ARI
Go back & read the advice I gave you in my prior post, or throw you
money to the wind.

the point that is lost to so many contractors is the fact that the
customers money is his to spend how he sees fit.
conventional wisdom would say upgrade the glazing & insulation prior
to upgrading the ac system, but sometimes the budget doesnt allow for
all of that, and the bottom line is when its hotter than hell outside,
we want our damned ac, period. Do we really care how much the
electricity costs us when the choice is stay cool or roast thru the
night trying to get a few hours sleep?
We all know his existing duct system is marginal at best, and when
connected to 13 seer equipment, he's going to have problems.
So now factor in a new air distribution system as well, crammed into
that low pitched roof. Now what's the budget?
OK I guess I started a crap storm at this place.........Let me ask you
this if my air handler is ok for a 3 ton unit then what about my
inside coils???? I know all of you are going to say I need to chance
that as well soooo....how do I find out what the maximum or what the
compatibility is for the inside coil??? Basically how do I tell if it
will handle a 3 ton unit??
I bow down to the A/C GODS!!!!
post the make, model & serial number for each component. If you cant
find a model number for the condensing unit, post the numbers on the
compressor. model numbers will tell us capacity, serial numbers tell

Its a 1997 Goodman air handler that will handle 30,000 BTU of cooling.
(With the correct refrigerant metering device)
The Condenser is a 24,000 BTU (25 if you want to get particular) and
probably 1981 but who cares.
Now go buy a new one and get a new thermostat, maybe a ductbooster and
a 25 yr labor warranty.
So the air handler will handle a 3 ton but nothing.....and you're
saying that the condensor I cuttently have is a 2.5 ton......I'm gonna
go with a 3 ton and I've already installed a new T-stat but I have no
idea what a duct booster is gonna look it up.......thanks a bunch I'm
sure your customers are very pleased with you since you actually have
some personallity and don't talk like a freaking manual or robot.....
30k is actually 2.5 ton and 24k is 2 ton. So your air handler fan will only
accomidate up to 2.5 tons and your current coil is a 2 ton coil. 3 ton is
likely to be oversized. You really need someone to do a load calculation to
determine the right size. Oversizing results in damp cold air and that
sucks comfort wise. If you really want to keep your current air handler you
might have to remove the inside coil and replace it with a cased coil that
goes with the new outside unit. That may or may not take some sheet metal
work. Air handlers are pretty cheap comparatively so simply getting a new
airhandler with the right coil probably will not cost much more than what it
will cost to retain your old one since you will need a new coil anyway and
you then will have all new. If you factor in the labor it's probably a
wash. You definately do not want to simply buy a new outside unit and have
it hooked to the existing coil.
