Our A/C has been having trouble keeping up this year. We only run it when the temperature inside the house gets into the mid 80's, which has happened the last few days.
IIRC, last year on a 90-ish degree day the A/C would run almost, but not quite constantly, but was able to maintain 75 degrees in the house. However yesterday when we turned the A/C, around on the temperature outside was 83 and falling and by 8pm or so it was about 75 degrees, but the temperature inside was still 77 (that's after the A/C was running constantly for 4 hours). Today the temperature outside was about 95 and the A/C hasn't been able to keep up at all - the temperature has gone up 3 degrees inside since we turned it on.
The air blowing out of the vents was 56 degrees when I checked yesterday, while the room temperature was 77; so a split of 21 degrees. Air filter is recently replaced. The same blower is used for heat in the summer and the system has no problem keeping the house warm.
What else should I check?
