Spring startup: beat the first heat wave
A proper startup uncovers the unit, reconnects and pressure-tests the water line, installs fresh pads, cleans the pan, and confirms the pump and motor run. Doing this in early spring means problems surface on a mild day — not during the first 100-degree week when every cooler company in town is booked solid.
Fall winterization: prevent freeze damage
Winterizing drains the pan and lines, shuts off and blows out the water supply, removes the pads, and covers the unit. The point is simple: water left in the pan and lines can freeze, expand, and crack the pump, pan, or supply line over an Albuquerque cold snap. Covering the unit also stops cold drafts from pouring in through the ducts.
Why the shoulder seasons are the smart window
Reddit's Albuquerque homeowners say it repeatedly: don't wait until mid-season for major work. Late fall and early spring offer the best scheduling, and it's far cheaper to replace a worn belt or pump during a planned visit than as an emergency call in July.
A month-by-month swamp cooler calendar for Albuquerque
Here's the rhythm most Albuquerque homes follow:
- April–early May: spring startup — uncover, re-pad, pressure-test, and tune before the first 90° days.
- June–August: peak season — monthly checks of pad saturation, water level, and airflow; expect reduced cooling during monsoon humidity.
- September: late-season check; a good time to fix anything that acted up.
- October–early November: winterize before the first hard freeze — drain, disconnect, cover.
Booking the startup and winterization at the edges of the season avoids the rush and the emergency rates.
What happens at a professional startup
A proper startup is more than flipping a switch. The technician removes the winter cover and inspects the cabinet and roof jack, reconnects the water line and pressure-tests it for leaks before they can reach your ceiling, installs fresh pads sized to your unit, cleans the pan, and runs the cooler to confirm the pump, float, belt, and motor all work. Anything worn is flagged with an upfront price so you can fix it now rather than during the first heat wave. It's the cheapest insurance against a mid-summer breakdown.
Signs you waited too long to winterize
If you've already had a hard freeze and the cooler wasn't drained, look for a cracked pan, a split pump, or a burst section of water line when you start it up in spring — all classic freeze damage. Cold drafts pouring in through the cooler vent all winter are another sign the unit and its duct damper were never sealed. If any of this sounds familiar, have the unit checked before the season so you're not surprised by a leak on the first hot day.

Startup and a tune-up pair naturally, as do winterization and any end-of-season repair. See seasonal startup and winterization, or call to book early.
