Water Damage Tempe is a water damage restoration company serving Tempe and the Phoenix metro — including Mesa, Chandler, Scottsdale, Gilbert, and Phoenix, and AC & evaporative cooler water damage is one of the services we handle most. This page covers what the work involves here specifically — the climate, the local causes, and what it costs — rather than what it involves in general.

What we do on the first visit

The first visit is an assessment, not a sales call. We identify the water category, check how far the water has migrated into flooring, subfloor, and walls, and take moisture readings to establish a baseline. We confirm whether the source is a slab leak, a failed appliance, or storm intrusion — and then you get a written scope with affected areas and any mold remediation as separate lines.

If we think a smaller mitigation job is the better spend than a full restoration, or the source needs a plumber before restoration can start, we say so on that visit — including when it means the smaller job for us.

What's included

Extraction and cleanup of water from an evaporative cooler's overflowing water trough, typically discovered on a roof or attic ceiling below
Assessment of ceiling and attic damage where a swamp cooler sits on the roof, a common Phoenix-metro installation
Central AC condensate line and drain pan overflow cleanup, a distinct mechanism from a swamp cooler failure
Moisture mapping across the ceiling and affected room to see how far the water traveled from the source
Coordination with an HVAC technician on the actual unit repair — clogged pads, float valve failure, or a cracked drain pan
Structural drying set up for the affected ceiling, attic space, and any room below
Mold risk assessment for attic insulation and ceiling cavities, since these leaks often go unnoticed until staining appears
Written scope for the water damage cleanup, separate from the HVAC repair itself

What this costs

AC & evaporative cooler water damage doesn't fit a single published price range, because the scope depends on what an on-site assessment of your specific property and situation finds. We give you a written scope and price after that free assessment, before any work starts.

When it needs doing

Ceiling staining directly below a roof-mounted evaporative cooler
A damp or musty smell in an attic space during cooling season
Water dripping from a ceiling vent or light fixture near the AC or cooler
Visible water trailing down an exterior wall below the roof unit
Cooling pads that look crusted with hard-water buildup and aren't cooling effectively

DIY shop-vac, the cheapest bid, or the job done properly

	DIY shop-vac	Cheapest bid	Done properly
Water extraction	Shop-vac and fans — surface water only, moisture stays trapped in subfloor and walls	Basic extraction, no moisture mapping	Truck-mount extraction plus moisture mapping to find water that migrated under flooring and into walls
Drying equipment	A box fan or two, days longer than needed	Minimum air movers, pulled early	Commercial air movers and dehumidifiers, sized to the room and monitored to a dry standard
Water category handling	Treated the same regardless of source	Rarely distinguished	Clean, gray, and black water handled to IICRC S500's different safety and disposal requirements
Mold risk	Not checked	Skipped unless asked	Moisture readings logged until the structure reads dry, since mold can begin in 24-48 hours
Documentation	None	Rarely provided	Time-stamped photos and moisture logs, useful for an insurance claim
If it's not actually dry	Mold shows up later, now a bigger job	Chasing a phone number that stopped working	We come back and re-check until the readings confirm it's dry

How it works

How AC & evaporative cooler water damage runs

Locate the leak source
Evaporative cooler overflow (a stuck float valve or hard-water-clogged pads) and central AC condensate overflow are different mechanisms with different fixes — we identify which one caused the damage.
Extract and assess
Water is extracted from the ceiling, attic, or affected room, with moisture mapping to see how far it traveled from the roof-mounted unit or condensate line.
Coordinate the HVAC fix
The unit repair itself — pads, float valve, drain pan — needs an HVAC technician. We coordinate while handling the resulting water damage.
Dry and document
Drying equipment goes into the affected ceiling and attic space, with a written scope for the cleanup separate from the HVAC repair.

Questions

AC & Evaporative Cooler Water Damage questions

Why do evaporative coolers cause water damage in Phoenix-area homes?

Phoenix-area homes commonly run evaporative (“swamp”) coolers, usually roof-mounted. Their water-trough overflow — often from a stuck float valve or hard-water-clogged pads that stop absorbing water properly — is a documented, distinct leak mechanism from a central AC condensate issue, and it typically shows up as ceiling staining directly below the unit.

Is this different from a central AC leak?

Yes — a swamp cooler leaks from an overflowing water trough on the roof; central AC leaks from a clogged condensate drain line or a failed drain pan, usually near the indoor air handler. Both cause ceiling or wall water damage, but the fix and typical damage location differ.

How do I know if it's my cooler or something else causing the ceiling stain?

Location is the first clue — staining directly below a roof-mounted swamp cooler points there first, especially during cooling season. We trace moisture readings back to confirm the actual source before assuming.

Is evaporative cooler water damage covered by insurance?

Often, if it's a sudden failure (a cracked pad frame, a stuck valve that just failed) rather than damage from years of known neglect. Document when you first noticed the staining and check your policy — gradual, unaddressed leaks are more likely to be excluded than a sudden failure.

Do you charge for an on-site assessment?

No. On-site assessments are free across Tempe and the Phoenix metro — including Mesa, Chandler, Scottsdale, Gilbert, and Phoenix. We assess the damage, explain the water category, and hand you a written scope with affected areas and any mold remediation broken out as their own lines.
