Not cooling enough.
I purchased a used mobile home last September. The seller had a new condenser unit (Goodman 2.5 ton) installed due to the attempted theft of the old unit. The line was cut and it was ran with no coolant. The evaporator was not changed, it is a Resco 2 ton unit. I don't know the age of the unit but it is most likely an old unit.
I moved in shortly after the new outdoor unit was installed. I had to have the installers back out because the ac was not cooling during the day. The tech stated that it wasn't hot enough on the day he installed the unit so he didn't have enough refrigerant in the system. He added some and it began cooling. This was at the end of the cooling season so I didn't have an opportunity to test it during really hot weather.
Now that we've hit the 90s here in North Carolina this spring, the a/c is not cooling during the day the same as before. I took the temperature from the floor register and the return grill, there is only a 10 degree difference.
I called the installer with my complaint because the outdoor unit is under warranty. He told me that most likely the evaporator coil is leaking. He said that he tried to get the seller to replace it at the same time as the condenser but was told if it wasn't leaking to leave it be. They leak tested it at that time and it was not leaking. However, as I mentioned above I had this same problem shortly after they installed the unit.
My question is, what could be causing my problem? The tech didn't come out here to check the outdoor unit. Could it be causing the problem I'm having? Neither unit has a problem with icing. Is it possible the evaporator is dirty? The filter is changed every month.

All mobile homes that i have ever seen have been 3 ton.
Sounds like a 2.5 ton on a 2 ton coil.
miss matched in size and efficiency.
could be miss matched refrigerant too.As iron sharpens iron so one man sharpens another Proverbs 27:17 NIV84

It is a singlewide from the 90s. The condenser is a Goodman gsc130181da. From what I saw online, the "30" indicates it's a 2.5 ton. The evaporator is a Resco cf5axa024000aaaa. The "24" indicates 2 tons, correct?
