Be aware that running the furnace fan on all the time in the summer (anytime you run the AC) can cause high humidity in your house. The condensation on the coils evaporates right back into the circulated air, instead of dripping and drying before the next cooling cycle. I thought running the fan would circulate air better and keep my computers cooler, but the high humidity made it feel muggy even at lower temps.
