Swamp Cooler Winterization in Burleson, TX
One hard freeze can crack a cooler’s water line, split the pump housing and leave you with a roof leak. Our swamp cooler winterization service drains, cleans, disconnects and seals your evaporative cooler before winter, so it survives the cold and starts clean in spring.

What Happens When a Cooler Is Left Running Into Winter
Burleson winters are mostly mild, which is exactly why coolers get forgotten. Then an arctic front drops temperatures into the teens overnight and the water sitting in the line, pan and pump freezes and expands.
Burst Supply Lines
Frozen copper or plastic tubing splits and floods the roof or attic when it thaws.
Cracked Pump & Pan
Ice expands inside the pump and water pan, ruining parts that were fine in fall.
Heat Loss & Drafts
An open cooler duct lets cold air pour in and warm air escape all winter long.
Rust & Mineral Damage
Standing water left in the pan speeds up corrosion and scale buildup.
How to Winterize a Swamp Cooler, Step by Step
Shut Off the Water
We close the supply valve and confirm no water reaches the cooler.
Drain the Line
The supply line is disconnected and blown clear so no water is trapped.
Empty & Clean the Pan
Sediment, scale and algae are removed and the pan is dried.
Remove Old Pads
Worn pads come out so mold and minerals do not sit all winter.
Protect the Pump
The pump is drained, cleaned and unplugged or removed for storage.
Cut the Power
We switch off and lock out the cooler circuit at the disconnect.
Inspect for Wear
Belts, bearings, motor and cabinet are checked and noted for spring.
Seal & Cover
A fitted cover goes on outside and the indoor vent is closed to stop drafts.

Winterization Questions
Plan for late October to mid-November, once you no longer need cooling and before the first hard freeze. Burleson can see freezing nights by late November, and arctic fronts can arrive with little warning.
Turning it off stops the fan, but water left in the line, pump and pan can still freeze. A proper winterization drains everything and blocks cold drafts through the duct.
Yes. A fitted outdoor cover keeps out wind, rain and debris, and closing or covering the indoor vent stops heat from escaping through the cooler duct.
We reverse the process: reconnect the water and power, install fresh pads, test the pump and float, and check the belt and motor. See our swamp cooler repair page for start-up service.
Shut off the water to the cooler right away and call us. We will find the split, replace the damaged section and check for roof or ceiling water damage.
You can handle the basic steps, such as shutting off the water and closing the ceiling vent. Our blog post on 6 easy steps to winterize your swamp cooler walks you through them. Roof-mounted units, pressurized lines and electrical shutoff are best left to a technician.
Pair It With Heating Care
