If you live in Albuquerque, chances are your home relies on a swamp cooler to beat the desert heat. And if you’ve lived here long enough, you also know that flipping the switch on your evaporative cooler isn’t as simple as just turning it on and hoping for the best. Without proper start-up prep, your system might not run efficiently—or worse, not run at all.
As someone who’s been in HVAC for over two decades and has worked on more swamp coolers than I can count, I can tell you: spring prep is the single most important thing you can do for your cooler’s performance and longevity. Let’s walk through what that looks like and why it matters here in the high desert.
What Makes Swamp Coolers So Effective in Albuquerque?
Swamp coolers—also known as evaporative coolers—use water and airflow to cool your home. They pull in hot, dry air, pass it over saturated pads, and push out cooler, slightly humidified air into your living space. It’s a simple concept, but one that works exceptionally well in our dry climate.
At B. Carlson Heating, Air Conditioning & Plumbing, we service every type of evaporative cooler you can imagine—from older roof-mounted units to high-efficiency ground-level models. We’ve seen firsthand how well these systems can perform when properly maintained—and how quickly things can go sideways when they’re not.
Why Swamp Cooler Startup Prep Isn’t Optional
Every spring, we get calls from homeowners whose systems aren’t cooling, are leaking, or just won’t turn on. Nine times out of ten, those issues could have been prevented with a proper startup.
Even worse, we’ve seen folks try to handle deep cleanings or part replacements themselves with equipment rented from the hardware store—only to end up injured or damaging their system. Evaporative cooler maintenance isn’t just a checklist; it requires careful attention, safe handling, and the right tools. Some of the equipment used in professional cleanings—like belt sanders or vacuum pumps—can cause serious injury if mishandled.
In short: it’s not just about efficiency; it’s about safety and protecting your investment.
6 Critical Steps to Prep Your Swamp Cooler for Summer
If you’re a DIY-inclined homeowner, here’s what needs to happen before that first 90-degree day rolls in:
1. Remove Covers & Inspect for Damage
Take off the winter cover and check the exterior for rust, corrosion, or rodent damage. Albuquerque’s wind and dust can be brutal, and small cracks or holes can become big problems fast.
2. Deep Clean Interior Components
Inside your cooler, hard water buildup and desert dust don’t take a season off. Clean the reservoir, float valve, water distribution lines, and pump screen thoroughly. If you’re using power tools or solvents, know what you’re doing—or leave it to the pros. Improper use can be dangerous or damage the unit.
3. Inspect & Replace Cooling Pads
If your pads are crusty, brittle, or smell musty, it’s time to replace them. Good pads make the difference between cool, clean airflow and weak, musty air. Bonus: replacing your pads helps improve indoor air quality too.
4. Check Water Lines & Connections
Make sure water lines are fully connected and not cracked from winter freezing. Leaks can damage your roof, walls, or ceilings—and in Albuquerque’s sun, even a minor leak can bake into a major stain.
5. Test Electrical & Mechanical Components
Look at your motor, fan belt, and switches. Is the belt tension right? Are wires frayed or brittle? Swamp coolers can be deceivingly simple—but when the motor shorts or the float malfunctions, it’s not always a quick fix.
6. Run the System Before It’s Hot
Don’t wait for the first 95-degree day to find out your cooler isn’t working. Turn it on now, listen for strange noises, and check for consistent airflow and proper water flow.
