It’s 90 degrees out with high humidity in Florida, vent is blowing 62-65 with a stick thermometer down the vent

typically we try to get/see vent temps of 45 or so degrees.

Suggest you get your system checked at a pro AC shop

Uncle Tabasco's we grease'em corner shop not such a good idea

BTW you did not provide make/model/yr

2014 F250 diesel. Just recently had the evap core and compressor replaced, blew cold in the low 40s for the first week.

What issues were you having with the compressor and evaporator?

Evap was leaking, and the compressor was shot

I'd be tempted to bring it back....may still have a leak......

That sucks !!! Should be in the 40s Fahrenheit.

Ya gots a leak !!! Take it back to the shop, it worked fine before refrigerant leaked out !

Cusser, good to see you on here more often, I always enjoy your posts,

If it worked well for a week and then it didn't, I agree that your A/C system probably has a leak or leaks...someplace. The trick is to find it (them) by having the shop check every part--including the new components--using a "sniffer."

Although buried deep inside the dash, checking the evaporator by "sniffing" the condensate drain tube often results in a "hit" if the evaporator is leaking. A compressor can leak at the shaft seal, case joints, control valve if applicable, and/or hose connections. So I would pay particular attention to those areas even though the compressor is new.

How does the condenser look? Any suspicious oil stains that might indicate refrigerant leakage? The condenser can take a real beating from road debris because of its location at the front of the vehicle, and they often leak due to damage and/or corrosion.

Any refrigerant tubing down low that might be subject to corrosion due to chemicals applied to icy roads in winter?

Yeah, I vote leak.

Given the average price of that job, I would take it right back.
