All air conditioners and cooling devices fail during late April, or first week of May, in Texas. It is a rule! Had it happen to my refrigerator, house air conditioner and all of the car air conditioners during the 10 years I lived there. It’s probably written in the Constitution in Austin! ;~)
You forgot the corollary to the Failure of Your Air Conditioner Rule.
Not only do the air conditioners fail, they are legally bound to fail after 5:00 P.M. on a Friday. That way you have to do without all weekend or call a repairman at triple overtime weekend rates.
