RUUD Model UAHF-036JAS - not as cold as used to be, but

Customer Question

RUUD Model UAHF-036JAS - not as cold as used to be, but cool; outside unit runs constantly after operating properly for hours; inside unit freezing-up. Cut off and let thaw, and it runs normally for a while. Is this low pressure/low freon ? Unit is mfg. 6/92.

Let's start though first making sure that filter is squeaky clean or new!2nd that blower is still moving air out of vents strongly.I'll hang tight for an answer

Icing is in the coil inside the ductwork in the basement, above the blower (upright heating unit). Filter is good and blower (air flow) is good.

Outside unit clean. No heavy buildup or pollen on the unit. You can clean this easily by hosing it down with a water hose.If this doesn't fix it then it sure does sound low on refrigerant unfortunately..... I told you everything I do before I even hook my guages up to check charge.

Yep, sprayed-out the coils outside with water hose. If pressure is low, does this indicate the need for more R22 ? Can R22 still be purchased ?
Expert:  Sean replied 1 year ago.
If pressure is low that indicates that there is a leak in the system somewhere could be extremely small or large.I would say since you freezing up usually.i see that's a average of a small leak.Yes you can still purchase r22 from a licenced HVAC company.Beware though it has really went up in price.
