Hi there folks, great forum. I am in Florida, Jacksonville
I have a 1 ton unit cooling an area of about 480 Sq feet, adequate as I am told. On days under 90, no problem, but if the temp goes over 90, the temp starts to drift. For example, it is 93 today and my thermostat now reads 78. I have it set for 75. About 830pm tonight the temp will come down to 75.
I've had the vents in the attic checked for leaks, nothing. I have a Fluke 116 and measure 97 at the low pressure line and 65 at the high pressure. This is inside at the blower end, outside measurements are slight lower. On a normal day my high pressure line is about 58 degrees. What could cause this drift in temp?
Also, suddenl I have water dripping from my filter to the drip pan. I 've had the coils cleaned so thats not it.
