Summers in Salt Lake City are famously dry, but also increasingly unpredictable. As temperatures climb into the 90s and 100s, staying cool isn’t just a matter of comfort — it’s essential for your health, home, and peace of mind.
If you’re trying to decide between sticking with a swamp cooler (aka evaporative cooler) or upgrading to a traditional air conditioning system, you’re not alone. Many Utah homeowners are facing the same question. Below, we’ll walk through how each system works, the pros and cons, cost factors, and why more Salt Lake City residents are choosing to make the switch.
What Is a Swamp Cooler?
A swamp cooler uses a simple principle: evaporative cooling. It pulls warm, dry outdoor air through water-saturated pads. As the air passes through, it cools down and gets humidified, then is blown into your home.
This process works well in arid environments like northern Utah. But the term “swamp” cooler is essentially ironic, having originated from the musty odor some units gave off when poorly maintained, which smelled more like a swamp than a desert breeze.
How Is It Different From Traditional AC?
Air conditioners don’t rely on evaporation. Instead, they use refrigerant and a closed system to remove heat and moisture from your home’s air. That cooled, dehumidified air is then circulated back into your space.
While swamp coolers rely on open windows or airflow, air conditioners are sealed systems that work best in closed, insulated homes.
Comparing the Two: Which One Works Better in Utah?
Salt Lake City’s dry heat in June and July is a natural fit for swamp coolers, but during wildfire season or August’s sudden humidity spikes, these systems often fall short.
Let’s break down some key differences
Swamp Cooler Benefits:
- Lower energy bills: Swamp coolers use about 75% less electricity than AC units.
- Eco-conscious: No refrigerants, fewer moving parts.
- Affordable upfront: Basic installations are less expensive.
Swamp Cooler Drawbacks:
- Humidity makes them ineffective: Not ideal when Utah’s weather shifts during monsoon season.
- Requires airflow: Open windows mean reduced security and more dust or allergens.
- Limited control: You won’t hit precise temperature targets.
Air Conditioner Benefits:
- Reliable in any weather: Hot, humid, smoky, or dusty, it handles it all.
- Better air filtration: Ideal during wildfire season or allergy flare-ups.
- Improves home value: Modern buyers expect central AC.
Air Conditioner Drawbacks:
- Higher energy use: More power means higher utility bills.
- More complex installation: Especially if your home lacks ductwork.
- Initial cost: Equipment and labor can add up.
Why More Salt Lake Homeowners Are Ditching Swamp Coolers
Historically, swamp coolers were ideal for the Wasatch Front. But that was before:
- Wildfire smoke became a seasonal concern (open windows = poor air quality).
- Summers started stretching into September and bringing humidity with them.
- Air quality and comfort became priorities for resale and year-round living.
The shift in Utah’s climate and expectations means more families are choosing central air for better air control, quieter operation, and 24/7 reliability.
Cost Comparison: What Should You Expect in Salt Lake?
Upfront Installation Costs
- Swamp Cooler: $1,500 – $3,000
- Central AC: $4,500 – $9,000+ (may require ductwork and electrical upgrades)
If your home is older and still running off a single rooftop swamp cooler, a full HVAC upgrade might include adding ductwork or new electrical panels.

Monthly Energy Costs
- Swamp Cooler: $20–$40/month
- AC Unit: $80–$180/month (depending on home size, insulation, and usage)
Maintenance Needs
- Swamp coolers need pad replacements, water checks, and frequent cleaning.
- AC units benefit from annual tune-ups and regular filter changes, but run more quietly and consistently.
What About Portable Evaporative Coolers?
Portable swamp coolers (like floor units or window models) can be useful for:
- Garages, workshops, or patios
- Renters who can’t modify HVAC systems
- Supplementing cooling in smaller rooms
But they come with limitations:
- Less power and coverage
- Still requires low humidity to work well
- Add moisture, which isn’t always desirable indoors
Your Top Swamp Cooler vs. AC Questions Answered
Can swamp coolers run in 100-degree heat?
Yes — if the air is dry. However, during August’s humidity and rainstorms, performance drops sharply.
Do portable swamp coolers use much electricity?
Not really. Most use far less than an AC unit, making them great for small, dry spaces.
Where are swamp coolers usually installed?
Typically on rooftops or through windows. Portable units sit on the floor or a counter and plug into a standard outlet.
Is a swamp cooler ever “better” than AC?
For small homes in very dry climates with limited use during peak humidity, yes. But for full-home comfort in Utah’s changing conditions, AC is the better long-term investment.
