How to Lower Humidity in a Coastal Home
Aim for about 30 to 50 percent indoor humidity. Correct AC sizing and operation matter most.
Humidity is the quiet comfort killer on the Grand Strand. It makes a 75 degree house feel sticky and encourages mold.
Know your target
Many sources recommend keeping indoor relative humidity between roughly 30 and 50 percent. An inexpensive hygrometer tells you where you are.
Start with your AC
Set the fan to Auto, keep filters clean and make sure the system is properly sized. An oversized system cools quickly, shuts off early and leaves the air damp.
Fix air leaks and ducts
Leaky ducts and gaps in the building envelope draw humid air inside. Sealing and insulation help.
Use ventilation wisely
Run bath and kitchen exhaust fans when showering or cooking and vent them outdoors.
Consider a whole-home dehumidifier
If humidity persists after the basics, a dehumidifier integrated with your system can help. We evaluate your home first so you only buy what you need.
