Buying Guide: Key Considerations For A Horse Trailer
- Trailer size and cooling area: Measure the interior length and width to estimate square footage. Choose BTU accordingly to avoid overworking the unit or undercooling.
- Ventilation and exhaust setup: Check window kit compatibility and whether you need an external vent for efficient heat removal. A simple seal kit helps minimize drafts during transport.
- Noise and vibration: Trailer use benefits from quieter models to avoid spooking horses and reducing stress for animals during cooling.
- Moisture control: In humid climates, dehumidification modes help maintain comfortable humidity levels, while evaporative coolers perform best in dry environments.
- Power requirements: Confirm electrical supply in the horse trailer. Look for Energy Star-style efficiency and avoid disrupting other essential equipment.
- Ease of installation: Consider models with window kits and simple hose connections to minimize setup time between stops.
- Maintenance and filtration: Look for units with washable filters to simplify upkeep and maintain good air quality for animals and handlers.
- Portability vs. capacity: Balance weight, size, and power. A mid-range BTU unit often provides the best compromise for trailers used for travel and turnout.
