Moving into a house with a fairly (less than 2 year old) new Space Pak system. When we did the inspection, it was not working - moving air, but not cooling. The inspector suspected there was a freon leak that was the cause. (The house has not been occupied for at least a year). The temperature differential during the inspection was seven degrees - I think 89 in, 82 out. The seller had a contractor out, and says it "must have been a loose wire" and is now blowing 50 degrees. Now, obviously, I can turn on the AC and see if the air [B]FEELS[/B] cool... But how else can I check? Can I just stick a cooking thermometer in the duct coming directly out of the air handler and take a reading? Thanks,

Hey all, We live in a 4yr old atrium ranch home (about 1800 sq ft main floor, basement finished with 1100 sq. ft.). In the summer the great room / kitchen living area is quite a bit warmer than the bedroom side of the house. I believe this is due to the vaulted ceilings and atrium windows. The sun hits the back of the house in the late afternoon and cooks it pretty good. I'm interested in the cost / benefit of running a window AC unit on the warmer side of the house to supplement the central air. Do any of you have an opinion on whether it is more cost effective for me to run the central air at a cooler temperature to make the warmer side of the house cooler (thereby also making the bedroom side even cooler than it is) versus putting in a window unit and leaving the central air temp alone or maybe cranking it up a few degrees? I'm not familiar with window units and how much they cost to run. Simply closing vents in the bedrooms / bathrooms doesn't really help much. We already had the atrium windows tinted to help reduce heat from the afternoon sun. Thanks in advance for any and all opinions!
