AC blowing out Cold Air- Help baby in the house

Hello,
I have a climate master AC model GCV018BG30CLTS. I recently had the vents cleaned and they found mold in the AC so they cleaned that as well. Now the AC is blowing cold air, I hear the compressor turn on but it turns off in a couple of minutes.

I removed the filter to see if that would fix the problem, but it is still blowing hot air.

Any advice?

Welcome to the forums.

If the compressor AND outside fan both cycle every few minutes then you'll need to have the refrigerant charge checked. It sounds like your system may be low.

Does your geothermal unit display any trouble codes when you temporarily short the 2 test terminals? (Like high head pressure trip or condensate overflow trip)

Some Geo units display diagnostic codes on the exterior of the unit but I don't think yours does.

I'm on my phone now but may be able to Google your manual when I get home.

So, the entire story is that I yesterday I had some AC people come and clean the vents and while cleaning they found mold on on the panel that you put the filter in. They used acid to clean the vent.

Now the compressor turns on and its cold for ten seconds and then it stops. so my question is, do you think the acid could of ruined the coil or do you think its just a leak ??? Please advise and thank you so much for answering, i read so many other post and u guys answered its kind of like your celebrities.

Thanks

Page 64 shows 3 LED's with 2 test pins on the control board.


page 68:
a slow flash on the green LED and 3 flashes on the red LED would indicate low pressure switch lockout.

The unit was working completely normal before they cleaned the ducts ?

I doubt the acid ate the coil but maybe they spilled it into the control area or got the control areas wet.

These units are extremely complex.

The control board is usually found in the lower section.

This is more advanced than a standard heat pump and many techs will avoid them.
