Palmetto Heating and Air Conditioning | Emergency HVAC Services in Charleston, SC

The high humidity in Charleston is the main culprit. Prevention starts with ensuring your AC system is properly sized and maintained to effectively remove moisture. We recommend annual maintenance checks where our technicians inspect ductwork for moisture and cleanliness, verify your system's airflow, and ensure the condensate drain is clear. Using a properly rated air filter and considering adding a whole-house dehumidifier can also significantly reduce the risk of mold growth in your ducts.

Clogged drain lines are extremely common here due to our humid, algae-prone environment. The stagnant water in the drain pan and line promotes algae and mold growth, which creates blockages. During our preventative maintenance service, we thoroughly flush the drain line with a specialized solution to clear existing clogs and inhibit future growth. We also check the condensate pan and the system's primary safety switch (float switch) to prevent potential water damage to your home.

Be on the lookout for a persistent musty odor when the system runs, increased allergy symptoms or respiratory irritation among household members, or visible mold growth around vents, on the insulation of ducts, or in the air handler unit. If you notice any of these signs, it's important to have a professional inspection. Our technicians can perform a visual assessment and may recommend duct cleaning and sanitization to remove contamination and restore your home's air quality.
