Every 3-5 years is the rule of thumb in the Lowcountry, sooner if you have pets, allergies, recent renovations, smokers, or visible dust at the registers. Charleston's humidity makes mold inside ductwork more likely than in dry climates, so periodic professional duct cleaning matters.

The average US home loses 20-30% of conditioned air through leaky ductwork, which can add hundreds of dollars to your annual power bill. Sealing and repairing ductwork typically cuts heating and cooling costs 15-25% per year and improves room-by-room comfort. Pair it with annual AC maintenance for the biggest savings.

Charleston summers regularly push outdoor humidity past 80% and an oversized AC alone can't hold indoor humidity at a comfortable 45-55%. If you feel sticky air, see window condensation, smell mustiness, or have warping wood, a whole-home dehumidifier integrated with your indoor air quality system is the right fix.

Start with a MERV 11-13 media filter to capture pollen, pet dander, and dust mites. For more severe allergies, a whole-home HEPA purifier provides hospital-grade filtration and a UV air purifier neutralizes mold spores, bacteria, and viruses. We assess your specific triggers before recommending an indoor air quality combination.
