Dehumidifiers in Arden & Asheville, NC
Humid stretches settle into homes here even on days that don’t get particularly hot, and an air conditioner that only lowers temperature without removing enough moisture can leave rooms feeling clammy at the right setting. A dedicated dehumidifier handles the moisture your AC alone wasn’t designed to fully manage. Our team can recommend and install the perfect dehumidifier to control moisture levels, enhancing comfort and indoor air quality.
Mountain Air installs and services whole-house and portable dehumidifiers for homes throughout Asheville, Arden, Hendersonville, and Brevard, NC. A whole-house dehumidifier connects directly to your ductwork and pulls excess moisture from the air as your system runs, rather than fighting humidity room by room with a portable unit. Mountain Air is there for your comfort on the humid stretches your air conditioner alone doesn’t fully solve.

FAQs
How do I determine the right size of dehumidifier for my space?
Determining the right size of dehumidifier for your space depends on various factors. First, calculate the square footage of the area you want to dehumidify. Next, consider the relative humidity level and any specific moisture issues. For moderate humidity, a general guideline is to select a dehumidifier with a capacity of 10 to 12 pints per day per 500 square feet. However, a larger capacity may be necessary for high humidity or severe moisture issues. Additionally, factors like room temperature and airflow should be taken into account.
Can a dehumidifier be used in basements or in cold temperatures?
Dehumidifiers can be used in cold temperatures and basements. However, not all models are designed to operate efficiently in cold environments. Look for dehumidifiers with built-in defrost functions or those specifically labeled for low-temperature use. Dehumidifiers in basements are particularly effective as they help control moisture levels and prevent mildew. Ensure proper ventilation and use a dehumidifier that suits your space’s size and humidity level.
What is the ideal humidity level to maintain with a dehumidifier?
The ideal humidity level to maintain with a dehumidifier is typically between 30% and 50%. This range helps prevent dust mites and allergens while creating a comfortable indoor environment. However, preferences may vary, so it’s important to find a humidity level that suits your needs and ensures the well-being of your space and health.
How is a whole-house dehumidifier different from a portable one?
A whole-house unit connects to your ductwork and treats the air throughout your home as your system runs, while a portable unit only treats the room it’s sitting in and needs to be emptied manually.
Why does my house still feel humid with the air conditioner running?
Air conditioners are built primarily to lower temperature, and only remove some moisture as a byproduct. A dedicated dehumidifier addresses the moisture directly instead of relying on your AC to do both jobs at once. Sustained humidity can affect wood, drywall, and finishes over time, and creates conditions that support mold and mildew growth. A dehumidifier addresses the moisture before it becomes that kind of problem.
How much maintenance does a whole-house dehumidifier need?
It should be checked during your regular system maintenance visit to confirm the drainage line is clear and the unit is pulling moisture correctly.
