I have a Lennox system r22 system not cooling properly. Low

Customer Question

I have a Lennox system r22 system not cooling properly. Low side 80psi high side 202 psi. Register temp drop is only 12 deg? What are causes? Expansion valve seems to be working. No Freon added for 7 years. That's the age of the unit, coils cleaned properly. No hard start cap. No noises from comp. Runs smooth. Any idea?
