Am I crazy for thinking of living in Durham, NC without air conditioning? Considerations: I get really really hot, have a somewhat crazy internal thermometer, I have lots of books, and I don't want to be miserable. Problem: we found a super cute house and it doesn't have AC. What to do? [more inside]

A/CFilter: Central A/C unit is 7 years old and ran pretty well until this year. Now it barely cools and has to run all day to do it. Have done all the homeowner checks (cleaned unit, checked filter and vents, sealed cracks and ductwork, etc.) A technician charged us $140 (having "cleaned" the unit and checked the coolant) to hold his cigarette up to the running unit and, using the smoke as his diagnostic tool, proclaimed that the fan was running...backwards. He insisted that this can happen with some units after a power surge. Did we just have sex with our clothes on? Or is he for real? Can a fan spontaneously run backwards? [more inside]
