HVAC Services Charleston SC | Call Southern Air conditioning and Heating

Uneven cooling is common in our area, often due to leaky or poorly designed ductwork, an incorrectly sized AC unit, or a failing component like a compressor. Our technicians perform a detailed evaluation of your entire system and home layout to pinpoint the exact cause—whether it's an airflow imbalance, refrigerant issue, or insulation problem—and provide a lasting fix to ensure consistent comfort in every room.

In Charleston's humid, pollen-heavy environment, we recommend checking your filter monthly and changing it at least every 1-3 months. A clogged filter forces your system to work harder, leading to higher energy bills, reduced cooling power, and uneven temperatures. More importantly, it can't trap allergens and dust effectively, impacting your indoor air quality. Regular filter changes are the simplest way to protect your HVAC investment and your family's comfort.

Our coastal climate demands specific preventative care. We recommend bi-annual professional tune-ups: one in spring for your AC to handle the summer heat and humidity, and one in fall for your heating system. These services include cleaning coils, checking refrigerant levels, inspecting electrical components, and ensuring proper drainage to prevent mold—all critical steps to improve efficiency, prevent unexpected repairs, and extend the life of your system.
