Seasonal cooler care
Swamp cooler start-up and winterizing
Time your start-up to El Paso’s real heat dates, not the calendar. When you are ready, a local provider can call you to schedule it.
When the heat arrives
June 12
Average date of El Paso’s first 100° day. Average last: August 3.
May 7
The earliest 100° day on record, in 2020.
June holds about 45% of all El Paso triple-digit days, and June 18 to July 1 is the highest-chance stretch. If you want the cooler running before the earliest heat on record, that means early May, ahead of the seasonal rush.

What a seasonal visit covers
The national cost source we use describes a seasonal tune-up as cleaning, inspecting, adjusting water flow, and checking pads and belt. Its national planning range is $80–$200.

Winterizing: when to shut it down
We have not yet found a sourced normal first-freeze date for El Paso, so we will not give you one from guesswork. We will add it once it is checked against National Weather Service normals.
What we can say: 2026’s cooling season ran long. Through October, El Paso logged 3,262 cooling degree days against a normal of 2,655, and October alone had 165 against a normal of 114.

A leaking cooler and El Paso’s water rules
El Paso Water’s ordinance page does not mention coolers by name. It does list two violations that a leaking or overflowing cooler can run into: water flowing into the street, and leaks not repaired within five working days. Violations can bring a Class C misdemeanor citation.
