I like my AC cold, and have run this unit at 70 F for the past 7 years without a hitch. The one air filter is changed monthly, anf the outside coils are clean. Sight glass shows everything clear. The unit has performed flawlessly, like a champ.
Recently, though, corresponding with some record high temperatures
07-31 105 08-01 108 08-02 110 08-03 111 08-04 109 08-05 107 08-06 106 08-07 106
beginning about the time the sun hits the outside unit/and/or the outside temp hits 101-102 the unit stops produding cold air. Up until that point, works perfectly, hits set point 70 with no problem. Just updated thermostat to Honeywell 7-day, same behavior, that is, later in the evening, about 8:pm or so, when the outside temp drops down below 100, the cold air starts up again and the house cools down as set on the thermostat. Ice cold, so freon seems good. Rinse and repeat with each 102-3+ F day so far.
Is the unit, which outside of these extremes seems to work flawlessly/no differently than last 7 years, protecting itself somehow with some type of automatic limiting switch? Or is this indicative of some breakdown that would require technician service?
Thanks for any insights. In the meantime, I'm warm now, I'll be cool tonight and tomorrow morning, and mid afternoon forward tomorrow I'll be warm again, unless something changes.
