I've read your posts where you discuss Goodman units. Maybe you'll take
the
time to offer an opinion for me.

I am the "lucky" owner of a package Goodman 12 SEER heat pump unit. I
live
in Central Florida and the unit has been in place for about nine months.
It
heats and cools wonderfully, no complaints there.

The problem I'm describing is not something new but has been around since
day one.

You have mentioned that Goodmans are noisy. Well, mine is noisy, but only
intermittently under certain conditions.

It's at is quietest in the A/C mode during the summer after the sun has
gone
down and the ambient temp has dropped somewhat. Sometimes under the above
conditions the unit will be loud when it first starts and then within a
couple of seconds the noise level drops considerably to what I consider
acceptable. Sometimes it starts loud and then slowly the noise level
deceases. During the heat of the day it's noisy during the entire on
cycle.

Now in the winter when in the heating mode it is noisy all the time.
Ambient temperatures are between 35* and 60* when it's running to maintain
70* inside.

I've noticed when it's heating and the unit is running in the "noisy mode"
if I press down on the grill that supports the large fan that the noise
level will decrease. I placed a 5 gallon bucket filled with water on the
center of the grill and that quieted it down quite a bit. That was when
the
compressor was running the in heat mode. Now today, with the high outside
temperature and in the cooling mode I discovered that removing the bucket
of
water reduced the noise level.

I don't know if my explanation is clear or not. If you can make any sense
of it I'd appreciate any comments you may offer, other than Goodmans are a
POS, I've read enough of that already.

Thanks in advance....

I had a 1999 10 seer Goodman on my last home. I took readings and it was
over 70 db at 10 feet away. 13 feet was my patio.

You can get a compressor blanket, for it. That will lower the DB some.
Check to see if the shipping bolts on the compressor were loosened. Most
builder units are not.
You can buy vibration isolator pads one for each corner and one under the
compressor. They will help, 1-3 db, if vibration is the issue.

Lastly there is a product called Zerol Ice. It is a lubricant for R-22. I
installed a can in my Goodman and the sound was lowered 3-5 DB at 10 feet.
It was noticeable quieter inside after the zerol ice install. Ya I had a
compressor blanket on it all ready.

I paid ~$50 bucks for the can. I was fortuante enough to have a friend of a
friend that had the special tool needed to open the can, another $30. 1
can will do up to 7.5 tons if I remember correctly.

It worked for me. It also lowered the amp draw a couple across the board.
I was satisified with the product. Now for the bad news. It was recommended
to me not to use this product on new equipment. I am not sure that I would
be inclined to install the product in something as new as yours.

I would recommend, in order
check shipping bolts, and install a sound blanket, less than $100 bucks and
goes on with velco. If you can get to the compressor you can install it.
install vibration pads between unit and concrete
Lastly call Nucalgon and get the name of a installer near you. NOT everyone
has heard of this product.

Have fun
