I've had this unit for a long time. Estimated installation was 1992. It has been a great unit.
Just today I turned it on and everything is working but the air is not cold. Is there anything I can do to figure out what is wrong? Is there a way to check and recharge if needed?
I've used it all summer without any problems or signs of failure.
Thanks for the reply. I looked at the section you mentioned. My set up is different from this one. Mine is a self contained Air Conditioner. Where would my A-Coil be located? And are these types of units able to be recharged? Fixed?
I looked at the plate on the side of the unit. It's so faded that I no longer can read it so I don't have a Model Number. Unless there is one located somewhere else on the unit.
It could be in need of a cleaning. Yrs ago when it was installed, the service man told me He or I never needed to do any maintenance to it. I thought that was rather odd.........but it has lasted all these years. Appreciate your help!
Thanks again for the reply. I'll take a look at the A-coil and clean if necessary. I did the other cleaning mentioned. The air seems to be alittle cooler.....but not cool enough to cool my home.
What does it usually cost to have a technician come out to check/charge the unit? I think at this point, that may be all I'll do if the cleaning doesn't help. I have no idea since I never had any problems with the unit.
Thanks for an honest answer. I priced these units an they are a tad expensive........
Again, thanks for the reply. Yes, this just happen very suddenly. It showed no signs of failure all summer. The unit always cooled very well.
I havent had the chance to open the unit up. Proibably wont be able to get to it till the weekend. Right now we are having cool tempertures.
Should I run the unit for awhile before I open the case? I know to disconnect the power before I open but prior to that?
The guy who installed it yrs ago, I thought said that when it goes, you just replace it. I directly asked about recharging the system each year or if I needed him to check it. He said NO, that when it goes, you just replace. I was worried becasue when I bought it was around the time they were changing the systems from Freon to some other type refridgerate and worried that mine wouldnt be able to be re-charged.
I'll let you know my findings. Hopefully it's something on the A-coil. Like maybe some insulation that got sucked through the duct work.
How do I test to see if the compressor is running? I know the fan on top is running..........but how can I tell about the compressor? I wondered about that after reading different post.
This weekend I will open the case and look for the A-coil. I really hope that it's just dirty. Should I run for awhile before opening?
When I was running it, It seemed like the air that was coming out of the ducts was at the same temperture as the outside air. Not sure since I had no way of testing.....but it sure did appear that way.
You can feel the bigger of the two refrigerant copper lines inside unit and see if it's cold. You can also open panel to get to compressor and listen for hte humm of it running.
You can also look for the drain line pipe coming out of unit from evaporator coil and see if it is dripping water.
I would clean it if possible before running.
Thanks,
Robert

As odd as it is and them being as old as they are, but I have another customer I am helping with his Suncutter 7448 packaged unit right now.
BTW, the drain will be below and in between the two large ducts attached to unit.
IF you are facing back side of unit, the duct on your right closest to the condenser fan is the return. The evaporator coil is upright behind that inside the unit.
You can see it well to see if it needs cleaning by disconnecting the flex duct, that is if you don't have a plenum box built around the two flex ducts.
Just remove any visible panels and look at all visible copper lines for signs of leaks.
Also, just out of curiosity, you don't happen to have a wiring diagram for yours do you ?
I don't have one as for as I know, but do have a parts pictorial of it.
Anyway, that would help greatly with other gentleman, his was given to him and he can't get it running and may have it miswired.
Trying to get him a wiring diagram.
Take care and best wishes,
Robert

Thanks for the additional information. Today I plan on opening the unit. I'll let you know my findings.
I saw that other thread. I was wondering if it was a unit like mine. I do not have a wiring diagram. I can not locate any paperwork for the unit.....which is odd because I keep everything. I'll continue to look....if I do find anything I'll let you know.
