A: The air temperature produced by your system depends on the temperature of the air going into it. Generally, the air produced should be 18°-20° below what enters the system. So if the entering air is 80°, the exiting air should be about 60°-62°. However, that only works on a system that has been running at least 15 minutes on a warm, dry day with a home that is about 80° inside. On a milder day, with an indoor temperature in the low 70′s, the air coming out may only be 15°-17° cooler than what enters.
