AC Leak Water Damage Repair in DeSoto, TX

Why AC leaks are common in DeSoto

An air conditioner pulls moisture out of the air as it cools. That water, called condensate, drips off the evaporator coil into a pan and runs out through a drain line. In a hot climate the volume is large. The National Weather Service in Fort Worth says summer highs are consistently in the 90s and often reach or exceed 100 degrees.

The drain line is the weak spot. Algae, dust and debris clog it, and when it backs up the pan overflows. If the air handler sits in an attic or a closet, the overflow reaches the ceiling or a wall within hours. A frozen coil can also melt all at once, sending more water than the pan can hold.

Other causes include a cracked drain pan, a loose connection, a dirty air filter that lets the coil ice up, and a failed condensate pump. Fixing the system is HVAC work. Our crews handle the water that has already left it, and a technician should look at the unit before it runs again.

What you see and what it means

First-hour safety steps for an AC leak

How crews dry an AC leak

The crew locates the water path. A moisture meter and a thermal imaging camera show how far the overflow traveled across the ceiling and into walls. Because the water is condensate, it is not sewage, but it can carry dust, algae and slime from the pan, so wet materials are not treated as clean.

Wet insulation is removed, since it holds water against the drywall. Soft or stained ceiling drywall is cut out in sections. Dry ceilings are dried in place with air movers and dehumidifiers. Readings are logged until the materials meet the dry standard, following the ANSI/IICRC S500 reference.

Repeated small overflows are common. Several seasons of drips can leave rusted fasteners, stained drywall and mold on the backside of the ceiling, which is why a moisture check is worth doing even if the stain looks old. Rebuilding is covered on the water damage repair page.

What changes the cost of AC leak repair

• How long it leaked. One overflow is small, while a season of drips affects framing and insulation
• Where the unit sits. An attic unit reaches ceilings, a closet unit reaches walls and floors
• Ceiling type. Smooth, textured and acoustic ceilings are repaired differently
• Insulation. Wet attic insulation is removed and replaced
• Mold. Wet materials that sat for weeks may need separate mold work
• Access. Tight attics take longer to work in

Insurance and AC leaks

In plain terms, the Texas Department of Insurance describes sudden and accidental water releases as commonly covered and continuous leaks as typically not. A drain line that clogs and overflows once is often the sudden kind. A drip that ran for months may be treated as a continuous leak, so the dates matter.

Photograph the ceiling, the pan and the drain line. Keep the failed parts. Permits may apply when HVAC components are replaced, and the City of Duncanville lists AC systems among work that generally needs a permit, so ask DeSoto Building Inspections at 972-230-9610 what applies here.

Preventing the next overflow

• Schedule a tune-up. A technician clears the drain line and checks the pan
• Change the filter. A clean filter keeps the coil from icing up
• Add a float switch. It shuts the system off when water backs up
• Flush the drain line. Some homeowners do this at the start of the cooling season
• Check the pan. A rusted or cracked pan needs replacing
