Done right

How swamp cooler leak damage is handled right

Follow the duct

Cooler water often runs down the duct and out the ceiling register, so the ductwork and the register boot get checked too.

Attic insulation

Insulation around the cooler drop gets soaked first. Wet sections come out before the ceiling can dry.

Fall shutdown

A cooler left full in fall can freeze and split its line. The team documents the cause for the claim file.

Why swamp coolers leak in Englewood

Evaporative coolers are common on Englewood's post-war ranches and bungalows, because the dry Front Range air lets them cool cheaply. Most sit on the roof and drop cool air through a single duct into a central ceiling register. The water that makes them work sits right above the living space, and the usual failures are:

  • A rusted-through steel pan on an older unit
  • A float valve that sticks open and overfills the pan
  • A cracked or split supply line, often from a freeze after the season
  • A clogged drain or bleed line that overflows onto the roof deck
  • Pads and louvers that let wind-driven rain into the unit during a storm

What the drying involves

Cooler leaks land in the attic insulation around the duct, then in the ceiling around the register. The drying team pulls wet insulation, checks the duct boot and the ceiling with meters, and dries what can be dried in place. Ceilings that sag or crumble are removed, the same way as any ceiling leak. Walls under a long leak are checked for water running down the top plates.

Shutting the cooler down right

Draining the pan and supply line, closing the valve and covering the cooler before the first hard freeze prevents most off-season leaks. The Energy Saver evaporative cooler page from the U.S. Department of Energy covers maintenance, and a frozen cooler line is handled like any frozen pipe.

Swamp cooler leak water damage questions

Where is the swamp cooler water shutoff?

Most rooftop coolers are fed by a small line tapped off a basement or utility room pipe, with a valve there. Some have a second valve near the roof penetration.

Can the ceiling around the register be saved?

If the drywall stays flat and meters dry within a few days, it is sealed and repainted. Sagging or stained plaster and drywall that stays wet is removed.

Is swamp cooler water dirty?

Water that sat in a pan for a season carries minerals, dust and algae, so it is often treated as Category 2. Fresh supply-line water is Category 1.

Does homeowners insurance cover a cooler leak?

A sudden failure, such as a split line or a stuck float, is often covered; damage from a long, slow leak or lack of maintenance may not be. Coverage depends on your policy, so it is worth checking with your own insurer.

Why did the cooler leak in winter?

A cooler line left full in fall can freeze and split, and it leaks when the weather warms. Draining and closing the line before the first freeze prevents it.

How long does drying take after a cooler leak?

Usually two to four days for an attic and ceiling once the wet insulation is removed.
