Clogged condensate drains. Pan overflow. Attic air handler cascade through ceilings. Houston's humidity puts massive load on AC systems — failures are predictable and the damage is significant. Direct insurance billing — you pay your deductible only.
Algae and debris — most common cause
Safety switch didn't trigger shutoff
Worst case — rains through ceilings
Refrigerant issues cause overflow
System loses charge, ices up
Coastal Houston specific pattern
Yellow ceiling stains, musty smell
Slow leaks colonize mold in cavities
Houston's gulf-coast humidity puts massive load on residential AC systems. Each year your AC removes 30 to 60+ gallons of moisture per day from indoor air during peak summer. That water exits through a small condensate drain line. When algae or debris clogs that line, the pan overflows. Attic-mounted air handlers cause the worst damage — the water rains down through ceiling assemblies, often discovered only after stains appear or sagging develops.
Dispatcher confirms HVAC system on/off, identifies attic vs. closet vs. garage unit, dispatches nearest crew.
Truck-mount extractors, thermal camera. HVAC unit shut off if still running. Drain pan and overflow switch inspected.
Ceiling thermal scan from below maps the full wet envelope. Attic inspection confirms unit-side conditions.
Sagging or saturated drywall removed. Wet insulation pulled. Antimicrobial applied to framing.
Air movers + dehumidifiers run continuously. Daily moisture readings documented. HVAC coordination for drain line repair.
Insulation replaced, drywall installed, texture matched, paint to match. HVAC tech installs float switch upgrade. Single insurance claim.
Every Houston summer brings HVAC condensate failures. Pre-positioned crews, established HVAC contractor partnerships, and standardized scope make this our most efficient loss type to handle.
HVAC condensate damage coverage is typically yes — sudden discharge is covered under standard Texas HO-3 policies. Gradual leaks face more dispute. The timing argument matters: was this 'discovered today' or 'has been leaking for 6 months?' Our documentation establishes the timing, and proper float switch and drain maintenance records support the sudden classification.
Annual HVAC maintenance records (we recommend yearly clean-and-check) document that you've been maintaining the system — supporting the sudden-event classification. We help you build that documentation case alongside the damage scope.
We know each major Texas carrier's playbook for this loss type
Most projects bill direct to insurance. Out-of-pocket cost is typically your deductible only.
Free on-site thermal imaging + scope documentation. No obligation. Attic inspection and HVAC repair quote from partner included.
We bill carrier for full water damage scope. HVAC repair is separate — usually $200-$600 for drain line clear, $400-$900 for float switch install.
Out-of-pocket HVAC condensate damage ranges by ceiling area affected, attic location, and mold colonization extent.
"AC pan overflowed and ruined a 12-foot stretch of ceiling. They found the full migration with thermal imaging, dried it properly, and worked with our HVAC company to install a float switch at the same time. Insurance covered everything beyond our $1,000 deductible."
"Slow leak dripped from our attic for months. Mold had colonized the insulation and ceiling cavity. Their TDLR remediation team handled the mold under the same scope. Total project closed in 18 days, insurance paid in full."
"Their HVAC partner had installed a float switch after our previous loss. When the drain clogged again last year, the switch shut the unit off. Total damage: $0. The upgrade cost $400 and saved us tens of thousands."
Annual HVAC maintenance (clean and check). Pour 1/4 cup of bleach down the condensate drain monthly to prevent algae buildup. Install float switches on secondary pans (every attic unit should have one). Inspect attic units quarterly for any signs of moisture. Cost of prevention: $200/year. Cost of a single attic cascade loss: $8,000-$15,000.
Sudden discharge: typically yes under standard HO-3. Gradual leaks running for weeks/months: often disputed. The timing documentation we build at intake distinguishes the two. Annual HVAC maintenance records support the sudden classification.
Sometimes — depends on saturation level and how long the leak ran. Slight staining with minimal saturation: yes, we apply stain-blocking primer and repaint. Significant saturation or sag: no, the drywall needs replacement. We assess with moisture meters before deciding.
Typical: 7-10 days for water damage scope (extraction, drying, demo, insulation, drywall, texture, paint). HVAC repair runs in parallel (usually 1-2 days). Larger losses or extensive mold: 14-21 days total.
Yes if you don't have one. Texas code now requires them on attic-mounted units. A float switch on the secondary drain pan triggers AC shutoff if water collects — preventing the cascade entirely. Cost: $200-$400 installed. Most-recommended single home water-loss prevention upgrade we make.
Because the moisture source is still active. Painting over the stain doesn't address the leak. The water continues to come through, and the stain comes back — sometimes with mold underneath. Stain-blocking primer (Kilz, BIN) only works AFTER the leak is fixed and the cavity is dry. We address both.
Drain pan overflow, frozen coil thaw, refrigerant leak, attic cascade — we identify, dry, coordinate HVAC tech, and bill insurance direct.
