How do I keep indoor humidity down in summer?

Start with the AC itself: proper sizing, clean coils, and good airflow let it dehumidify as it cools. If the home still feels sticky, a pro may recommend a whole-home dehumidifier or duct repairs — oversized short-cycling systems are a common culprit.

Why does water drip from my ceiling vents?

That is usually a clogged condensate drain: the AC pulls gallons of moisture from humid air daily, and when algae blocks the drain line, water backs up and overflows. Shut the system off to stop the damage and have a pro clear the line and check the drain pan.

How often should AC be serviced in Greenville?

At least once a year before cooling season — and with Greenville's near year-round runtime, many pros recommend a second mid-season check. Constant use wears capacitors, contactors, and coils fast, and a tune-up catches the small problems before the hottest weeks.

Greenville is deep in cooling country — air conditioners here run most of the year, and the long, humid summer is the season that decides how long HVAC equipment lasts.

Near the coast, salt air and storm exposure add their own tax: outdoor condensers corrode faster, and hurricane-season winds and flooding batter equipment that was never anchored for it.

When heating or cooling trouble hits your Greenville home — an outdoor unit rattling after a storm — AirFlow HVAC connects you with an independent local HVAC pro. Tell us what is happening and we will match you with a pro nearby, fast.

Homes here, and the HVAC problems they get

Local housing notes

1970s–2000s suburban builds where builder-grade ACs are reaching replacement age in waves.
Newer high-efficiency builds — tighter envelopes, but still dependent on proper humidity control.
Raised cottages with air handlers and ductwork underneath, exposed to humidity and storm water.

Common local HVAC issues

Corroded outdoor units: salt air eats condenser coils and cabinets near the coast.
Oversized ACs, clammy homes: short-cycling systems cool fast but never dehumidify.
High indoor humidity: even a working AC can leave homes sticky if airflow or sizing is off.
Condensate overflows: algae-choked drain lines back water into drain pans and through ceilings.
Upstate winters bring ice and sleet that coat heat-pump outdoor coils, forcing long defrost cycles and pushing auxiliary heat strips into expensive overtime.
Spring pine pollen buries rooftop and ground-level condensers in yellow dust, and a clogged coil drives head pressure up while cooling capacity slides down.
Older mill-era bungalows near downtown hide undersized return ducts behind plaster, starving the blower and leaving back bedrooms warm no matter the thermostat setting.
Afternoon thunderstorms roll off the Blue Ridge with frequent lightning, so surge protectors on the disconnect and a clean condensate trap earn their keep every summer.

Greenville FAQs

Most South Carolina jurisdictions require a mechanical permit for AC and heat-pump replacements, and the installing contractor typically pulls it. Confirm permitting is included before work starts.
