anybody got a Carrier PTAC unit charging chart??? I have 167 units that the
previous guy put piercing valves on every one of them.....on the suction
side only!!! (it quit coolin' so it must need FREON!!)


been having problems with them losing the charge.... and/or frying the
compressors....I have been putting them back into service after cleaning the
units and servicing them with braze-in taps.....18 degree superheat, 20
degree delta-T

unfortunately I don't have access to either an accurate scale or charging
cylinder to "weigh in" a charge...any help???

thanx

Couldn't your local Carrier dealer fax you one?

The PTAC units have gone the way of the Window unit....disposable junk.

They're not meant to be serviced/repaired, just tossed.

It does seem they have really been cheapened - product wise but not
price.
GE has some nice electronics but some cheap plastics. Amana especially
seems to be worse and NOISY!!! The last Friedrich we put in melted its
discharge grille cuz the filter got too dirty. I haven't seen a Carrier
lately but if I recall, they went to 1 motor instead of their usual 2.

The charge must be weighed in. Invest in a scale since you've got 167 units.
How cheap can your boss be?

If they are taken care of (properly cleaned and motors oiled).. just like
window units they should last 15 - 20 years.... some of these units that I
have to deal with are only 1 - 2 years old!!!!

I'd appreciate a copy of the charging chart. Is it specific to a brand or
manufacturer?

Thanks.

Just curious -- many years ago, John Zink was a common air
conditioner brand name here. Any relation?

According to the Carrier Blue Book, they haven't been made in over
a dozen years. I haven't seen one here for awhile...of course, Phoenix
is a good proving ground for A/C's.

I'm not sure the technicalities but they got renamed Sunbeam and now
evolved into AAON, a popular national account rooftopper.

Ever hear of ADA? I think it is Air Distribution Associates. Funky old
bombs, one of our McD's has them.
