Little brick bungalow in the midwest US, 800 sq. feet. New Heil HVAC system installed Mar. '06. The central AC is 2-ton, r-22, 10-seer.
The hi yesterday was around 100 F. At 5:05 it was 87 in the house, and I set the Tstat to 79. At 6:45 it had cooled to only 81 F.
So, it cooled only 6 F. in 100 min. with outside temp of 100.
The system is under warranty. This is I think the first time it's been hot enough to really stress-test it. There's no way I'd expect really fast cooling with a 2-ton unit, but 17 min. per degree of cooling sounds kinda suspect.
I'm thinking maybe low charge, maybe even tiny leak.
Your knowledgable opinions are enlisted.
Thx, Puddin'
