No he wasn't the lowest, he was the highest of 3, highly recommended by
others.

Let me ask you this then. I am ABSOLUTELY sure he has the blower speed on
either low or medium low. I know this because he had it on high temporarily
when installing the furnace, and then he set it to the very lowest setting.
When I switch between heat and AC, the blower works at the same speed.

Does the Amana SV 80 not have a separate cooling-mode blower speed setting?
I have looked at the wiring diagram and there's just a box there saying See
Installation Instructions. If someone could look up information on how to
set the blower speed during AC operation I would be extremely greatful.

If you're posting a reply, please only reply to alt.home.repair. Thank you.
I apologize for cluttering up the wrong group and I will use this message to
move the thread over.

Thanks again.

First off you really need to post this at alt.home.repair
Second, I gotta ask 2 questions (pretty sure I already know the answer)
1) Did the contractor actually *do* a heat load/loss calculation??
2) was your contractor the lowest bidder??

Now for a little information....
A correctly sized system is supposed to run constantly to maintain the
design comfort levels (usually 70 - 72 for heating and 75-78 for cooling)
at
the design temperatures for your area. This should have been explained by
your contractor. A correctly sized system will *maintain* the design
comfort
levels....not bring a really hot or really cold house to your comfort
levels. Bigger is *not* better. A correctly sized system will be a whole
lot
more cost effective to operate.
A correctly sized system with correctly sized ductwork will also be much
quieter.
BTW... a thermostat is a temperature controlled ON/OFF SWITCH...turning it
up/down isn't gonna make the system work any harder.
Set the thermostat and forget it.... the only time you should even need to
touch it (other than switching from heat to cool) is if you are going to
be
gone for more than a day or 2...then set it back about 10 degrees.

Hi,
I'll try and give as much info as possible, whether needed or not. 1250
sq
ft, brick ranch, 1956 construction, original windows. Insulation -
so/so.
Cleveland, OH area - we'll see a few mid-90s days a year.

Had a Amana SV 80 furnace 70,000 BTU (maybe 75,000, whatever amana makes
in
that "size") put in in October. Worked great through the winter, though
I
wish it was quieter. We decided to have the installer wait and replace
outdoor AC unit in spring. Indoor coil was a 2.5/3 Ton unit, he says he
installed the 3 Ton valve in it. His plan was to have a 3 ton indoor
setup
paired to a 2.5 ton outdoor unit.

I just had the AC compressor put in this week. It's not cooling all
that
great. He said a 2.5 Ton was plenty big. I warned him that this house
got
hot easily (black roof) and that the previous AC had to literally run
all
day long on hot days just to keep the temp even. On hot days with the
old
unit, whatever temperature I turned the AC on at, was the temp it was
able
to simply "hold steady" during the day, only starting to drop after the
sun
went down.

The other day I turn on the new AC. Outdoor 85F. Indoor starts at 84F
and
hits 80.5F in 2 hours. Humidity drops 6% during this time, from 36% to
30%.
So it's better than the old system but this still seems weak to me. I'm
no
expert but I would have thought more than 3.5 degrees in 2 hours. I
measured the air coming from a medium-length duct run as 63 F.

I noticed he did NOT add any refrigerant to system. I realize it's
pre-charged from factory but the manual says it's charged for up to 15'
of
pipe if I'm reading correctly. I have about 30' to the indoor coil.

Also, how do I set the blower speed of the SV 80 furnace during cooling?
I
found the diagram that shows which color wire to use for lo/med lo/med
high/high during heat operation, but it just says "check installation
instructions for setting blower for cooling operation". I didn't find
the
info in the installation instruction booklet. Isn't there a separate
speed
setting during cooling? I'm thinking going up one speed may help me
out.

What should I do first? He did measure the pressure of charge at
install.
If it was near the min of the range and he added some would that help me
noticeably? Can I bump up the blower speed? (I know the air won't dry
as
much, but I don't like very dry air, messes up my sinuses.) Should I
bite
the bullet and request he get rid of the 2.5 ton outdoor unit and put in
a
3
ton?

THANKS!!
Brian
