We completed construction on our home in Florida in 7/2006. We have 2
Bryant central air units (one 3 ton unit and one 4 ton unit). Last
week I noticed the 3ton unit couldn't keep up with the cooling during
the afternoon hours.
I called the A/C company that put the units in during construction.
Here is what happened:
Visit 1: (last week): the tech tells me the system is low on freon
either because it was never filled properly or there is a leak
(they'll test for the leak if it gets low again and the problem
resurfaces). I received a bill for $90 and was told the unit would
catch up that night then should be fine. The tech noted that air was
now coming out 16 degrees cooler than when going in so I should now be
Visit 2: after I called and advised there was no change the boss sent
out his "best diagnostician" who "made some adjustments" with the air
handler which is up in the attic and noted we now had 18 degrees of
cooling and the unit would be fine once it catches up tonight, but
again there was no change.
Visit 3 (today): the boss decided to send a team to figure it out, the
2 original techs plus one more. They each seemed to have their own
diagnosis of the problem based on what my wife had overheard
(unfortunately I wasn't around the whole time). They had simply told
me the plan was to gather info and have Bryant diagnose the system.
Now I'm told the reversing valve needs to be replaced to the sum of
$720 even though the unit and part is under warranty (I'm told it's a
lot of labor to replace it).
I called another company who will come in the morning for a free
estimate/2nd opinion. They told me the problem didn't sound like
something caused by a bad reversing valve but they'd come out and
I'm looking for any advice on how to proceed with and what questions I
should ask, as I'm looking at a lot of money and not confident these
guys know what the real problem is.
I got a 2nd opinion and found out there was no filter drier in the air
handler and I'm told that really screwed the system. Could this be
true? Full details below.
-I spoke with the owner of the company that installed and has been
servicing the unit. He says one of his techs felt the TXV valve was
bad but they worked with Bryant over the phone who said the reversing
valve was bad based on the data given. He said it would be close to
$1000 to replace both and I should call Bryant and bitch to see what
they'd do since the unit is only 14 months old.
-I called a new hvac company for a 2nd opininon. They sent a tech
out. He measured the refrigerant psi for the lines attached to the
condenser. He noted the pressure was climbing from 200 to almost 400
psi, at which point the release valve kicked in and it would soon
start all over again. He had eventually gotten the pressure stable
and said he believed there was contamination in the line and the issue
was now fixed (although I found no change later on). This is the info
he gave me on what he did:
-found system overcharged
-found system heat pressure raising to 450psi from 210
-pumped system down, inspected piston at liquid line at condenser &
screen at condenser. Found a small chunk of possibly brazing rod
-flushed nitrogen through lineset to make sure there was good flow
-pulled system into deep vacuum
-recovered some of refrigerant to proper charge
-system working properly
-suction & liquid pressure steady
- 10 degree superheat LO 80
-12 degree subcooling Hi 200
-18 degree delta T - compressor amps 10.1
I called the company back and they sent out another guy. He energized/
de-energized the reversing valve using heat and cooling but it did not
He had been looking at the air handler and says there's no filter
drier installed and now the system needs to be cleaned out, txv
replaced, filter drier installed and we mostly likely don't have a
filter drier on our other system (although that one's been functioning
I looked at the documentation for this unit and the filter drier is
listed under optional equipment but another page says it is suggested
in all field-connected split-system heat pumps. Can the absence of
this filter really cause the issue? If so, is this a major mis-step
of the installers to not put it in?
Could be, be many systems out in the field have no filter/drier and they
operate just fine.
I'm not agreeing that one shouldn't be installed, but not having one isn't
the root cause of your problems.
Call Bryant????? Why?????
The parts are still under the 5 yr manufacture's warranty!
If the installing HVAC company won't work with you on the installation of
the warranted parts (on a 14 month old system), they'd never get another
dime from me!
Most competent, honest contractors would be happy to work with you, as
problems like this is very unusual and don't happen all that often. If it
does, they need training!
There was contamination, yet he didn't charge the unit with new refrigerant?
I smell more incompetence and bullshit!
Means little without complete details.
Wow, another genius...
Which proves my point of it's not really required for proper operation.
However, it's there for protection!

I called Bryant yesterday morning. They told me to contact a Bryant
dealer in my area and have them conduct the following:
Bryant wants the report and will work with the dealer. A few hours
later, the owner of the company I called came out and straight away
said there's nothing wrong with the system after quickly checking it.
We went up to the attic and he showed me that the duct work was just
run wherever and not according to my original blueprints and 2/3 of
the house was on the 3ton system and 1/3 on the 4 ton system. I
agreed to pay him to do a load calc and we'll take it from there.
So let me see if I understand, they should have done a load
calculation in the first place and also hooked your ductwork up
correctly and you agreed to pay him for something he should have done
in the first place? Dumbass. I guess you must really like taking it in
Never said the new company should not get paid. He shouldpay them then
send their bill to the first company and insist it get paid or he goes
to the local tv station. That will get someones attention pdq.
