Savannah guide
Why Savannah homes feel sticky, how your AC removes moisture, and practical fixes from thermostat settings to system sizing.
As warm, humid air passes over the cold indoor coil, moisture condenses and drains away. That is why comfort in Savannah depends on more than temperature: a house at 76 degrees with low humidity feels much better than one at 72 with sticky air.
If the thermostat fan is set to ON, the blower runs even when cooling stops, and water sitting on the coil can blow back into the house. Setting it to AUTO lets moisture drain away between cycles.
A unit that is too big cools the air quickly and shuts off before it has run long enough to pull out much moisture. The result is a cold, clammy house. When replacing equipment, ask for a proper load calculation rather than matching the old unit's size. Variable-speed systems run longer at lower output, which helps with humidity.
Leaky ductwork in a hot attic can pull humid air into the system. Sealing ducts, weatherstripping doors and running bathroom and kitchen exhaust fans all reduce the moisture your AC has to fight.
All that moisture has to go somewhere. Algae in the condensate drain line is one of the most common summer service calls in coastal Georgia. Ask your technician about flushing the line during maintenance, and never ignore water around the indoor unit.
