28psi is low for how warm it is in the summer. Should be well up around 45-55psi.

 

Sounds like the system is might be low on R134a. And if that is the case, you have a leak.

check the charge on the system if it is low, you have a leak. 9 out of 10 times its the condensor

Change the condenser and vacuum and recharged the system
