AC Not cooling like it should...maintenance guy gives up...help!


ok I used the thermometer to test the input and output vents for the inside unit. 77 going in (what hte thermostat currently says) and 60 coming out. The weird thing is that it's mid 70's outside right now, I'm keeping it on just to test it out. Shouldn't it be at LEAST as cool as outside since the air it cools comes from out there???

It's comfortable in here, but not cool like we want it. I'll be opening the windows for tonight, but with those numbers, it looks like the unit is fine, so why can't we get the apartment to cool?????

another thing u mention in the description is that the maint guy recharged the system to make it work "properly",

if he overcharged the system, it can make the pressures inside the system work at higher pressures thus causing lower cooling capacity if it works with an "orifice" metering device

the compressor could also be overheating and shutting off intermittently (internal overload safety device) and when that happens the condenser motor keeps on running, giving the impression that the outside unit is "turning on" and running normally

u need an expert to check the unit out if u believe there is something truly wrong with the system

The air the A/C cools comes from inside the building through the return air grills not outside. For the Pros I know it don't cool it removes heat , just sayin for the layman out there.
