Summertime heat can be brutal – not just for you, but for your animals too. When temperatures rise, barns can become hot, stuffy, and uncomfortable, putting livestock at risk for heat stress and even serious health issues. While air conditioning might seem like the dream solution, the cost and impracticality of installing a full HVAC system in a barn or agricultural structure makes it an impossible task for most farmers and ranchers.

Fortunately, there’s an affordable, easy, and effective alternative: portable evaporative cooling.

Why Heat is a Big Deal in Barns

Barns are often built for ventilation, not climate control. During extreme heat, especially in closed or metal barns, temperatures can spike quickly. This heat doesn’t just cause discomfort; it can impact animal health, reduce productivity, and increase the risk of heat-related illnesses.

Animals like horses, cows, goats, and chickens are particularly vulnerable:

• Horses in prolonged exposure to high temperatures can result in heat stress, heatstroke and problems such as dehydration, and muscle spasms.
• Cows produce less milk and become lethargic.
• Chickens can suffer from reduced egg production or even fatal heatstroke.

When animals are uncomfortable, they eat less, move less, and are more prone to illnesses which cost you time and money.

The Problem with Traditional Barn Cooling Methods

Most barn owners rely on one or more of these methods:

• Shop fans or ceiling fans – These help with air movement but rarely reduce actual ambient temperatures.
• Opening windows or doors – Effective air movement if there is a breeze but still doesn’t do anything to reduce temperature rates.
• Misting systems – These can cool the air slightly (more effective in dry climates) but often leave floors and equipment wet, which can lead to slippery surfaces, mold growth, rusting, or discomfort for animals that can cause illness.

These methods can result in some improvement, but they’re not always enough, especially during summer heatwaves.

Why Evaporative Coolers Are a Game-Changer

Evaporative coolers (also known as swamp coolers or desert coolers) use water and airflow to reduce the temperature of the ambient air. With proper air circulation and ventilation, this is the most effective way to cool outdoor spaces. As hot air passes through the water-saturated cooling pads, the air is cooled down and blown into the surrounding space.

Here’s why they’re a perfect fit for barns:

•  Lowers ambient temps by 10–25°F depending on climate conditions
•  No refrigerants or compressors – much more eco and animal-friendly
•  Energy-efficient – Less electronic components, making it the most eco friendly option compared to HVAC systems
•  Portable and easy to operate – move it where it’s needed (foaling stalls, milking stations, tack rooms, cattle barns, travel trailers, etc.)

For barn environments where ventilation is key, but climate control is tough, swamp coolers can change everything.

How to Choose the Best Evaporative Cooling System for the Barn

If you’re shopping for an evaporative cooler for your barn, here’s what to consider:

• Coverage area: Make sure the unit can cool the size of your barn or specific zones (most range from 700–3,000+ sq ft). Look into accurate CFM ratings
• Portability: Look for built-in wheels (without brackets) so you can move the unit easily. The more compact in size, the easier it is to mobilize.
• Tank capacity: Larger water tanks mean longer run times without refilling or having to keep a water source attached.
• Durability: Outdoor and barn environments can be rough—choose a cooler with tough housing, quality components, and a low-maintenance design.

Pro tip: If you already have shop fans or ceiling fans installed but need more of a boost, use your cooler in conjunction with the fans to maximize the cooler air circulating throughout the entire barn.
