I have a new Payne heat pump we purchased in the summer. Now that the
unit is in winter operation the noise is driving us crazy! The unit
is quite and heats the house great but every 1.5 hours or so is lets
out a sound like an airplane taking off. I belive it puts itself in
reverse to keep the outside coils from freeing up. But should it be
so loud that it wakes people up?
I should have been weary of an obviouse knock-off of "Train" heat
pump. Is this realy going to be a Payne in the butt? My insurance
company replaced my York with the bottom of the barral I guess right?
One last thing, it's running off the York thermistat, could the
mismatch be causing the problem? Any thoughts would be great!
FWIW, Payne equipment had been around a long long time, and is not
intended to be confused with Trane. Payne may actually have been around
longer than Trane. Payne is made by Carrier corp, and from a reliability
standpoint is fairly decent, but they have to be the noisiest POS ever
made. I have spent hours trying to quiet them down and stop the rattling
panels, with very limited success. The York stat should not cause your
problems. Did a home warranty company install this unit? Around here, it
seems most Payne equipment is mixed and matched with little concern
about compatibility. Larry
Yes, a home warrenty did replace the unit. I've had this new unit
since July and never heard the noise until heating season, so I'm ass-
u-me ing, the defrost is only needed in the winter. The unit works
great and the house has never been warmer even with an ice storm that
coated the entire unit. But to coin a phrase from the Grinch: The
noise, the noise, the noise, noise, noise, noise........
I mean, it really is loud, and it not a rattling sound it's more
like ... did you ever hear an electric fogger or electric paint
sprayer buzz? It's that sound only 3 times as loud. Emagine that
sound every 1.5 hours all night long, every night. The crazy thing
is, the dog sleeps right through it!
But you all agree, maybe I should have the installer back for a
checkup? (it's going to cost me $50. deductable).
You need to find the airplane and get rid of it.
When it reverses, it should only wake up the dog, not you.
It will only be a pain in your side. Leave your butt out of it.
I didnt know insurance companies replaced heat pumps. Usually a
qualified hvac company does that.
Any mismatch can cause problems. Why would you let them do that?
If the head pressue is running excessively high at the beginning of
the defrost cycle, then the changeover will be excessively noisy as
well. If head pressure is high at the end of the defrost cycle you'll
have the same noise issue. In the former case the likely culprits
would be low indoor airflow or an overcharge. In the latter case a
stuck or incorrectly located defrost sensor would be the likely
Have you checked the air filter? If it's clean then you might want to
have a professional look the system over.
Other than that, yes, as the other poster said, Paynes are typically
noisy in a vibration/rattling sense. That doesn't seem to be what
you're referring to though.
Funny you should say the beginning and ending. The first noise lastes
about 7 seconds then about 3min later I get a noise equally as loud
but only for 3 sec. My filter is a bit dirty so I'm going to replace
the filter this weekend and monitor the start and finish noise, then
report back here.
At least I have a plan to follow now!
There was a service bulletin sent out on this. It recommended a "quiet
shift" defrost board to alleviate this noise problem (that exists on
some models). Ask your local Carrier, Bryant, or Payne dealer about
this. What the board does is shut the compressor down for one minute
and then starts it back up with the reversing valve switched.
Your unit may already have one of these boards. There is a dip switch
on the upper right hand corner that says "quiet shift" above it. It
can be switched on or off. We leave them in the off position unless
there are noise complaints.
Well, that's some great information. This is a brand new unit so I
would assume the dip-switch is present. Even if there were no noise
complaints, it seems to me that jamming the compressor in reverse
rather then shutting it down, then going in reverse, would be better
for the compressor's longjevity.
I can't wait to try this!
Not so Lucky....
I found the circuit board but no sign of a dip-switch.
I posted some pictures at http://www.schmooseme.net/payne-in-the-ear.htm
I'd love to get my hands on this circuit board and install it myself.
I know the home warrenty service would never pay for it, would you
belive they would not pay for the legs this unit has to sit on?
Thanks for your help Richard!
Did ya ever notice that when home owners post on here that they want *free*
advice, or *free* instructions on how to fix their 20 - 30 year old POS
furnace, its because they have already screwed with it and they ended up
with a lot more damage than they started with. And all because they were too
cheap to call a *competent*, licensed, insured, professionally trained, HVAC
technician to diagnose and correct the original problem. Then there is the
thought of <gasp> replacing the furnace.... they can drive brand new cars,
and live in nice homes, but can't be bothered to get their comfort systems
serviced, or replace them when their past their design service life.
What kills me is that they call us rip-offs when it would have been a whole
lot cheaper to pay a competent tech, and get it done right in the first
Usually, but that doesn't apply to the OP, yet. The unit is in fact
new, and the complaint is valid. Noise is not covered by the standard
warranty unless there is a defective part causing it, and even then
only the part is covered. In this case the parts work, but the
engineering could be said to have failed. I'm not fond of bad
engineering, so I tend to be sympathetic to its victims. Both the
part and the labor should be covered by Carrier for the upgraded
board. It isn't the customers fault that Carriers engineers produced a
piece of shit unit.
I thought it best for my own sake to add this:
Not all of their units are pieces of shit, but that one is. OTOH,
competition causes all manufactures to offer builders grade systems.
Even so, if they can't produce a cheap unit that doesn't wake up the
neighbors then they should send spies out to the other manufactures to
figure out how they manage to do it. I worked on exactly the same
model unit just last week, and it was a noisy SOB. I guess I still
have some pissed-offedness left over from that. There's nothing I can
do to quieten the unit short of replacing it. :)
There is a market for cheap, but damn!
Bullshit Steve he hasn't messed with the fucking unit it at all far as I can
tell simply stated it either has a defective reversing valve or it has one
that is too fucking small for the job replace it with one that has a big
enough coil so it can quickly shuttle the spool regardless of head pressure.
