The fan on setting has been an space of controversy for many years. Because the air dealing with fan runs continuous, any moisture left on the coil and drain pan dumps again into the airstream when the compressor is off. When you add in return duct leaks, extra humid air enters the system.

Economizer controller settings ought to handle economizer airflow. Nevertheless, many economizer louvers don’t seal 100% hermetic, so they’re a chief location for humid air to enter the air dealing with system. Louver upgrades can present higher seals and cut back leakage.
Latent Capability Suffers
Some HVAC gear have restricted moisture or latent elimination capability. Roughly 85% of the gear’s whole cooling capability goes to decreasing the house temperature. That leaves 15% to take away humidity from the air.
It doesn’t take lengthy to overwhelm a system while you combine damp crawlspace air and 90°F exterior air with a 72°F dew level. So, you’re left with a system that runs continuous, leaving a constructing chilly and clammy. Tools efficiency will proceed to undergo until you cope with the additional moisture load at its supply.
Subsequent Steps
