Why Is My House So Humid?

December 27th, 2020 | Cooling & Heating

Homeowners in South Carolina are familiar with the high heat and humidity that living on the coast brings. No one is surprised when humidity starts becoming a problem, but when it is not being managed properly inside your home, the risk of mold and mildew growth increases. High humidity inside your home also creates bad smells from mildew and makes your furniture damp, your mirrors, and windows foggy, and can be downright uncomfortable. When your AC is not doing the job of keeping humidity at bay, you may need to make an appointment for air conditioning service; however, if you want to investigate the problem yourself, you may find one of these issues is to blame:


  • Daily Activities: There are a few daily activities that naturally increase humidity in the home such as showering, cooking, exercising, running the dishwasher or laundry machine, or any other processes that use water. 
  • Poor Ventilation: Humidity from daily activities is usually dispersed through proper ventilation of the home. Kitchens, bathrooms, and laundry rooms usually need special ventilation fans to keep moisture and humidity at bay. 
  • Wrong Size AC: One of the most common culprits of high in-home humidity seen by AC conditioning service in Charleston is the wrong sized AC unit. An air conditioner that is too large for the home, cooling will happen too quickly and in short spurts which gives little time for dehumidifying in between. 


In addition to these three reasons for high humidity, weather is also always a factor in changing humidity levels and is usually temporary. 

Removing Humidity 

An air conditioning service can be called to inspect your AC to ensure the dehumidifying components are working properly and the AC size is the right fit for your home. You can also run a transportable dehumidifier to remove excess moisture, keep windows open and fans on, and make sure your home is properly ventilated. 

If your AC unit needs a checkup from a professional air conditioning service, call AirMax Heating and Cooling at 843-595-8273.
