Indoor Air Quality Services in North Charleston, SC

Persistent allergy symptoms that improve when you leave the house, musty odors, excessive dust, visible mold, and sticky humidity in the summer are all classic signs. Family members with asthma flaring up indoors is a strong tell. We offer in-home IAQ assessments that measure pollutants and humidity to pinpoint the cause.

A combination usually works best: a whole-home HEPA purifier captures 99.97% of particles down to 0.3 microns (pollen, dander, mites, mold), and a UV air purifier neutralizes bacteria, viruses, and mold spores. Upgrading your filter to MERV 13 is a good first step. Sealing leaky ductwork usually doubles the impact.

In Charleston, dehumidification is the bigger need. A whole-home dehumidifier integrated with your AC system pulls indoor humidity down to a healthy 45-55% during muggy summers, which prevents mold, dust mites, and that sticky feeling. In winter when heat strips run, a small humidifier can help with dry skin and respiratory irritation.

Standard 1-inch filters every 1-3 months. High-efficiency 4-inch media filters every 6-12 months. Pets, allergies, and how often the system runs all shorten that timeline. Higher MERV is better for allergies but must be matched to your blower so you don't choke airflow. We check filters during every AC maintenance visit.

Yes. A coil-mounted UV-C lamp continuously sterilizes the evaporator coil, drain pan, and surrounding ductwork — the three places mold loves most in the Lowcountry. It's one of the cheapest IAQ upgrades you can install on existing equipment.
