A duct system in Tega Cay cools through a long, humid season, breathes some of the heaviest pollen in the country and often runs through a crawlspace. This is what we actually find here, and what we check on every visit.
Two-story Tega Cay homes usually cool the upstairs through attic ductwork that bakes all afternoon. Heat ages flex duct, dries out taped joints and sags loose straps, so the upstairs - the rooms that need the air most - get the least of it.
Separated joints under a Tega Cay house spill cooled air into the crawlspace all summer. The system runs longer, the floors can feel clammy from the humidity that follows the pressure change, and the fix is sealing and repair under the house rather than a larger AC.
Gaps in return runs are common in South Carolina homes, and a return that leaks pulls unfiltered air from attics, garages and wall cavities - dust, insulation fibers and fumes included - and sends it through the house, bypassing the filter entirely.
Warm upstairs, cold downstairs is the standing Tega Cay complaint, and ductwork is usually behind it: leaking attic joints, undersized returns for the second floor and flex runs kinked during construction. An inspection separates the duct causes from the equipment ones.

It removes a real reservoir. Tega Cay pollen loads the return side heavily each spring, and the system keeps recirculating it after the season ends. Cleaning the trunk and returns out means the house stops re-dosing itself. It is not a medical treatment, but most families notice dust settling more slowly afterward.
Rooms that never reach temperature, an AC that runs long cycles, dust returning days after cleaning and weak airflow at far registers. Under Tega Cay homes, separated crawlspace joints are the standing culprit, and professional mastic sealing is the lasting fix.
Often yes, for a different reason: construction dust. Builders run systems during drywall and paint in many Tega Cay subdivisions, and that dust packs the trunk before move-in. An inspection shows it plainly on camera - if the system is clean, we tell you that instead.
Yes - offices, restaurants, retail, churches and multi-unit buildings across Tega Cay, scheduled around your hours. Commercial systems get the same method: the negative-air machine sealed onto the trunk, every run cleaned individually, and a camera record of condition.
Where ducts run through attics and crawlspaces - most Tega Cay homes - leaks spill cooled air outside the living space, and sealing them means the AC runs less to hold the same temperature. We check for leaks on every inspection and tell you plainly which work would pay off.
No — and be wary of anyone who does. Every duct system is a different size and condition, so a phone price is a guess that changes at your door. Our inspections and estimates are free: a tech looks inside your actual ductwork first, then gives you one clear price before any work starts.
