A gym is one of the toughest environments for aircond — 30 people generating 300-600 watts each, treadmill motors adding heat, and Malaysia's tropical climate outside. Getting it wrong means unhappy members and equipment damage.
Why Gyms Need More Cooling
An exercising person generates 4-6x more heat than a resting person. 30 people working out = 9,000-18,000 watts of body heat alone, plus equipment and solar heat gain.
Capacity Calculation
Standard office rules don't apply. For gyms: Cardio area: 800-1,000 BTU/sqft. Weights: 600-800. Yoga studio: 500-600. A 2,000 sqft gym needs roughly 40-50HP total — far more than the same space as an office.
💡 Quick Sizing
2,000 sqft gym: Minimum 2x5HP cassettes (barely adequate). Recommended: 3-4x5HP (comfortable at peak). Premium: VRF with zoned control. Cost: RM25,000-45,000 installed.
Best Types for Gyms
Ceiling cassettes are most popular — 4-way distribution, mounted safely out of the way. Ducted for premium look. Wall-mounts only for small boutique studios under 500 sqft.
Ventilation: Often Forgotten
30+ people exercising rapidly consume oxygen and produce CO2. Without fresh air supply: fatigue, dizziness, body odour buildup. Use exhaust fans + filtered fresh air intakes feeding into aircond return.
Humidity Control
30 people sweating = 80-90% humidity. Creates slippery floors, equipment rust, mould. Consider commercial dehumidifiers if aircond alone can't keep humidity below 65%.
Maintenance Schedule
- Filters: weekly (gym air is much dirtier)
- Professional coil cleaning: every 2 months
- Chemical wash: every 6 months
- Full system check: quarterly
