A/C not blowing correct temperature

I recently recharged my A/C system and put the correct amount of refrigerant in. It used to not work at all due to a major leak in the compressor. I replaced the compressor, pulled a vacuum on the high and low side, recharged the system and it blew colder than it was before. However, my climate control goes down to 60 degrees (this is as low as it can go). When I put a thermometer on the ac vents, it reads about 62-64 during the day (In Florida heat) when it should be 60 degrees. At nighttime, it blows 60 degrees with no problem. What could be causing this? Is this normal? Also, 60 degrees still does not seem to be very cold as modern-day cars. Is the lowest setting on a car typically 60 degrees or does it happen to be this model where they put it to where it can only go down to 60 degrees? Thanks!

Hello,

The reading of 62-64F during a hot day is typical. The loss is due to ambient heat, which is completely normal. That is why you get to 60F at night due to coolant temperature.

As for the 60F being the lowest setting, that is typical of just about all the vehicles on the road.
The only thing you want to make sure is that the blower is blowing at the highest setting. If for some reason the full blast or Max AC does not function, it can 'feel' like the AC is not working properly.

Thank you, Sean. That does make me feel better. I will need to put the A/C on full blast at night to see if it is still registering the correct temperature. When you say, "If the MAX AC does not function, it can 'feel' like the A/C is not working properly", what do you mean by that? Because during the hot day, I have put it on blast where it still is cold, but not as cold as if it was on low, but I may be over thinking it now due to my previous issue in the question which has now been answered.

I meant; you want to make sure that all the different fan speed if functional. Like from low speed to high. As long as they are working and you can feel the fan is blowing at the highest speed, it should be fine, as you are getting a good temperature reading.
Hope this answers your question.

Let me know of any concerns.
