AC Leaking Water in Marietta, GA
When an air conditioner leaks water in Marietta, the cause is frequently a clogged condensate drain line backed up with algae or sediment, a frozen evaporator coil thawing rapidly, a dirty air filter restricting airflow, a cracked or rusted drain pan, a failed condensate pump, or low refrigerant levels causing ice buildup. From historic neighborhoods around Marietta Square and Whitlock Heights to Sope Creek, East Cobb, and residences near Kennesaw Mountain National Battlefield Park, our own technicians are dispatched directly across Marietta to diagnose and resolve your AC water leak.

Signs Your AC Is Leaking Water
Catching an active cooling condensation leak early protects ceilings, flooring, and electrical components from costly structural moisture damage.
Water Pooling Near Indoor Air Handler or Furnace
Standing water collects around the base of the indoor unit in your utility closet, basement, or attic platform.
Water Stains or Active Dripping on Ceilings and Walls
Brown moisture rings or active water drips appear on drywall below attic air handling equipment or upstairs duct runs.
Ice Accumulation on Refrigerant Line or Evaporator Coil
Frost or solid ice forms across the indoor coil or copper line, melting rapidly into puddles once the cooling cycle stops.
Musty Odors or Visible Mold Growth Near Supply Vents
Damp, mildew-like smells circulate through the home as stagnant condensate water lingers inside ductwork or the drain pan.
Overflowing Drain Pan or Float Switch Shutting Off System
The secondary condensate drain pan fills to the brim, triggering the emergency float safety switch to halt system operation.
AC Running Continuously with Weak Airflow and Rising Humidity
The air conditioner struggles to cool indoor spaces while airflow drops and sticky indoor humidity rises alongside coil frost.
