We recently had a contractor install a new unit (a Bryant Puron 2.5
ton in a 1500sq/ft 3br/2ba home) a couple of months ago. This week
we've had some really warm weather with temperatures in the 90s
nearing 100 degrees. The problem is the unit is not cooling the house.
The unit runs all day and doesn't drop the temperature below 78
degrees. Our older unit never had this problem.

We called the contractor that installed the unit out and he said that
was normal. He told us that these units won't cool more than 20
degrees below the ambient air temperature. He also said that the fact
that our ducts are in the celing makes this problem worse. Something
doesn't sound right here. I mean, our old unit cooled the house fine
and that unit was smaller (2 ton).

What's going on here? Is he correct, ignorant or simply lying? Can you
guys educate me on this? Should this unit be capable of cooling the
house better than it's doing now?

Not expert here, but it sounds like the guy is trying to swat you
away, at least for awhile. Exactly how 'cool' does the new unit
actually get the house now, vs what your old one got it to?

I would wait for some good feedback here and get your ducks in a row
before you pressure the AC guy too much more. That way you'll maybe be
able see through some of the smoke screen excuses he might be giving
you.

Good luck. Post how it all gets resolved.

I'm in Texas. It's hot here. My house is bigger than yours, and 3 tons
will cool it as low as I want to go.

The "20 degree" rule of thumb is across the A/C. So if your house is
at 100 degrees, the A/C should be able to blow (more or less -- it's
just a rule of thumb, not Gospel) 80 degrees. Then, once the house is
cooled down to 80 degrees, it should be able to blow 60 degrees. Etc.

Btu is Btu. If the new unit is larger, it should cool to a lower
temperature than the old one. Proper sizing aside, the higher capacity can
remove more heat. Proper sizing gets into things like humidity control
where to big is no good. If the 2 ton unit was good, the 2.5 ton should be
at least as good at reducing the temperature.

I'd do a quick check of the basics first. Are the duct leaking? Was
something left undone or is airflow blocked? Check the temperature of the
air entering and leaving the AC. It should have about a 20 degree drop
across the coil. Cooler at night with no sun load? By cooler, I mean the
differential between outside and inside temperature. Personally, I think
there is a problem and since it is new, get him back to check things, such
as the pressures in the unit. There may have been a leak.

There is a lower limit, of course. At 100 degrees, a properly sized unit
won't get it much more than 20 to 25 degrees cooler than outside, but if the
old one did, the new one should.

The design and sizing of a system is also somewhat dependent on where you
live. We live in the Phoenix area. Few people here would be happy with 95
degrees inside on a 120 degree day, a 25 degree differential. We can
easily cool our house down to 70 degrees on a 120 degree day, although we
usually keep it at 75 degrees.

Wayne,

Your reply makes me curious........how many tons of a/c do you need to be
able to get a 50 degree temperature drop for how many square feet of living
space? What would be a typical electric bill during the summer months?
Thanks,

It's a 3 ton high efficiency unit. House is 1500 sq. ft. The walls have a
6" insulation space with R50 insulation, as does the roof. The house is 1-
1/2 years old. We're on "averaged billing" which runs $165/mo. year round.
It's also an all-electric home.

Got a thermometer? Put it in front of the AC air intake. Record the number.

Now put the thermometer in an outlet vent. Record the number.

That's the 20 degrees difference he's talking about. Outside temperature is
irrelevant.

Even if it's 100° outside, you should be able to cool your inside to
astonishingly low temperatures (given suitable insulation, leakproofing,
etc.). I've seen ice storage sheds keep blocks frozen with a piddly 1/4 ton
window unit (and two feet of cork on the walls, ceiling, and floor).

Now *IF* you get a 20° differential AND you still can't cool below 76°, then
the heat's getting IN faster than the AC can pump it OUT (insulation, open
doors, etc.).

2.5 ton is not big enough for 1500 sq. ft. Unless you have very high dollar
windows and are super insulated with 6" walls. Should have been 3 or even
3.5 ton.

What's going on here? Is he correct, ignorant or simply lying? Can you
guys educate me on this? Should this unit be capable of cooling the
house better than it's doing now?- Hide quoted text -

we have 3 ton and space pack cooling a 3500 sq ft 90 yr old original
window, poorly to non insulated all original leaker. It was even
guarnteed in writing by the installer to give a 30f drop which it
exceeded when it reached 113f here in chgo after it was installed 20
years ago. I dont know where you get your numbers.

nearing 100 degrees. The problem is the unit is not cooling the house.
The unit runs all day and doesn't drop the temperature below 78
degrees. Our older unit never had this problem.

We called the contractor that installed the unit out and he said that
was normal. He told us that these units won't cool more than 20
degrees below the ambient air temperature. He also said that the fact
that our ducts are in the celing makes this problem worse. Something
doesn't sound right here. I mean, our old unit cooled the house fine
and that unit was smaller (2 ton).

If you had 2 ton and it cooled you fine before why did he want to put
in a more expensive 2.5 ton and why did you agree to it, a larger unit
will run less, but remove less humidity and that you didnt want, but
to the point of cooling something must be wrong on the install if you
are sure you had 2 ton before and it cooled better. The new larger
unit wont remove as much humidity since it will run less, if it was
put in right.

Did you pull a permit, is one required in your area, what does the
contract say because inspectors help by checking work for free. If I
had a non performing , wrongly oversized AC that will now leave me
more humid I would make the installer put in the right unit, I bet he
didnt do a load calc in writing, which is to your benefit if you did
have 2 ton before, You hired a crooked hack if he oversized you, as
you state you cooled before with 2 ton.

Did the guy come back and checkthe refrigerant level? If not, call
him and keep calling.

When we bought a new system years ago, they turned it on and left. It
never cooled worth a damn and I could never get them back out to check
it. When they set it up originally, the guy said somebody would be
back out to check it and get the freon level right. That person never
came. A couple of years later I got somebody else out who found the
thing was quite low, and once that was fixed it worked much better.

A couple of things you can check.
1. I figure when they upgraded you to a 2.5-ton from a 2-ton condensing unit
they replaced the evaporator coil. If so, look around the system and see if
you have any air leaks.
2. The system may have never been charged properly in the first place. I
would have another service tech out from another company come out double
check their work and see if you need further work. Just have him check the
system, labor only, and if he finds problems then contact the company that
did the work.
