Why does my house smell musty when the AC starts?

Musty startup odors usually mean mold or mildew on the evaporator coil or in the ductwork — common in Columbia's humidity. A pro can inspect the coil and ducts, and duct cleaning plus moisture control addresses the cause rather than the smell.

Should I repair or replace my old air conditioner?

With the extreme runtime Columbia demands, older systems lose efficiency fast. A pro weighs age, repair history, and refrigerant type — if a major repair approaches a large fraction of replacement cost on an aging unit, replacement usually wins.

Columbia 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.

Condensate management is the local specialty: ACs pull gallons of moisture from the air daily, and when drain lines clog with algae, the water has to go somewhere — usually through a ceiling. Ductwork in hot, humid attics and vented crawl spaces sweats, leaks, and grows mold.

When heating or cooling trouble hits your Columbia home — an AC blowing warm on a sweltering afternoon — 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

Slab-on-grade ranch homes with supply ducts running through scorching attics.
Concrete-block homes that hold humidity and challenge even well-sized systems.
Historic homes with retrofitted ducts or mini-splits working around plaster and pier foundations.

Common local HVAC issues

Year-round runtime wear: compressors, capacitors, and fan motors log extreme hours — failures cluster in the hottest months.
Ductwork mold: humid attics and crawl spaces turn leaky ducts into mold farms; musty odors at startup are the tell.
Storm damage: hurricane-season winds, flooding, and flying debris batter outdoor equipment.
Weak-heat freeze surprises: the rare hard freeze finds heat pumps on backup and idle furnaces failing to fire.
Sandhills heat: the sandy Midlands run hotter than the coast, and attic temperatures soar past 140 degrees — radiant barriers and sealed ducts fight the bake.
Fire-ant nests: fire ants love electrical contactors — mounded nests inside condensers cause mysterious no-cool calls each summer.
USC rental churn: student rentals near campus cycle yearly — neglected filters and propped-open doors punish even new systems.
Tropical-storm prep: storm remnants drench outdoor units and flood disconnects — elevated pads and a post-storm electrical check are cheap insurance.

Columbia FAQs

At least once a year before cooling season — and with Columbia'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.
