Pueblo summers come in hot and dry, with plenty of sunshine and afternoon highs pushing into the 90s. That dry air makes swamp coolers (also known as evaporative coolers) a popular option for many homes and small businesses in Southern Colorado. But lately, more Pueblo residents are asking the same question: Should I stick with my swamp cooler or switch to air conditioning?
In this guide, we’ll explain how both systems work, compare pros and cons, and help you decide what’s right for your home, especially in a climate like Pueblo’s, where conditions can shift from dry heat to muggy monsoons in a flash.
What’s a Swamp Cooler, and How Does It Work?
Swamp coolers use evaporative cooling, a natural process that relies on dry air and water. Here’s the basic idea:
- Warm outdoor air is drawn into the unit and passed over damp pads.
- The water in the pads evaporates, cooling the air and adding humidity.
- A fan then pushes that cooler, moist air into your home.
This works well in low-humidity areas like Pueblo, particularly during late spring and early summer. But once humidity rises, like during July and August thunderstorms, the efficiency drops fast.
Why Is It Called a “Swamp” Cooler?
Older models had a reputation for producing a musty odor if the pads weren’t cleaned regularly, earning them the unfortunate “swamp” nickname.
How Does Central Air Conditioning Work?
Air conditioners use refrigerant and a closed-loop system to remove heat and moisture from the air:
- The AC pulls warm indoor air into the system.
- It passes through coils containing refrigerant, which cools the air and pulls out humidity.
- The now-cool, dry air is circulated back into your home.
AC systems are fully enclosed, meaning they don’t rely on open windows or external airflow. This makes them ideal for year-round indoor comfort, regardless of weather swings.
Swamp Coolers vs. Air Conditioners: Pros and Cons
Swamp Cooler Advantages:
- Energy Efficient: Uses far less electricity than AC.
- Eco-Friendly: No refrigerants, fewer moving parts.
- Lower Upfront Cost: Easier installation for many Pueblo homes.
Swamp Cooler Drawbacks:
- Humidity Problems: Less effective during Pueblo’s monsoon season.
- Open Windows Required: This can let in allergens, dust, and unwanted heat.
- Inconsistent Cooling: Can’t always maintain steady indoor temperatures.
Air Conditioner Advantages:
- Reliable in All Weather: Works through heatwaves and humid afternoons.
- Better Air Quality: Filters allergens, smoke, and pollutants, critical during wildfire season.
- Boosts Resale Value: Central AC is a major selling point in modern homes.
Air Conditioner Drawbacks:
- Higher Energy Use: May increase utility bills in the summer months.
- Upfront Installation Costs: Can be more expensive than a swamp cooler, especially if ductwork is needed.
- Ongoing Maintenance: Requires regular filter changes and tune-ups.
Why Pueblo Homeowners Are Switching to AC
Swamp coolers served Pueblo well for decades, but today’s climate and lifestyle expectations are different:
- Climate Change = More Humidity: Late summer storms bring higher moisture levels, making swamp coolers unreliable just when you need them most.
- Better Air Matters: Whether it’s wildfire smoke or seasonal allergies, sealed AC systems with filters offer protection that open-window cooling can’t.
- Home Comfort is Year-Round: Swamp coolers are seasonal; AC works whether it’s June or September.
Breaking Down the Costs in Pueblo
Installation Costs:
- Swamp Cooler: $1,500–$3,000 (rooftop unit + basic setup)
- Central AC: $5,000–$10,000+ (depending on ductwork and home size)

Monthly Energy Use:
- Swamp Cooler: ~$15–$50/month
- AC System: ~$80–$180/month depending on usage and system efficiency
Maintenance Needs:
- Swamp coolers need frequent pad replacements, seasonal cleaning, and waterline checks.
- AC systems benefit from annual tune-ups and filter changes, offering quieter, more consistent performance.
Portable Evaporative Coolers: A Third Option?
If you’re not ready for a full system change, portable swamp coolers can help cool small spaces.
Pros:
- Garages, shops, or porches
- Temporary rental situations
- Homes with low cooling needs
Limitations:
- Won’t cool an entire house
- Not effective during Pueblo’s humid late-summer days
- Still requires fresh air and adds moisture indoors
Pueblo Homeowners’ FAQs
Can swamp coolers handle 100-degree temperatures?
They can, as long as the air stays dry. But when Pueblo’s summer storms roll in and humidity rises, their cooling power takes a noticeable hit.
Are swamp coolers installed inside or outside the home?
Whole-home swamp coolers are typically mounted on the roof or in a window. Smaller, portable units are designed for indoor use in single rooms.
Do swamp coolers use a lot of energy?
Nope. They’re actually one of the most energy-efficient cooling options out there, especially when compared to traditional air conditioning.
Is air conditioning a better option than a swamp cooler?
That depends on your needs. If you’re looking for consistent cooling, better air quality, and a fully enclosed system, AC is often the smarter long-term investment.
