Understanding Tonnage vs. Physical Weight
When you look into how much an HVAC system weighs, you’ll find a key difference. HVAC pros talk about “tonnage” in a way that’s not about the system’s weight. Instead, it’s about how much cooling it can do.
The idea of tonnage comes from a cool historical method. One ton of cooling is the heat needed to melt one ton of ice in 24 hours. This means it’s about 12,000 British Thermal Units (BTUs) of cooling power per hour.
- 1 ton = 12,000 BTUs of cooling capacity
- 4-ton system = 48,000 BTUs of cooling power
- Actual physical weight varies by system type
Home HVAC systems usually range from 1.5 to 5 tons. The actual weight of an HVAC system depends on several things:
- Unit size
- Materials used
- Specific system configuration
Tonnage | BTUs | Typical Weight Range |
---|---|---|
1.5 ton | 18,000 BTUs | 100-200 lbs |
3 ton | 36,000 BTUs | 250-350 lbs |
5 ton | 60,000 BTUs | 400-500 lbs |
Knowing this difference helps you choose the right HVAC system. Remember, tonnage is about cooling power, not the system’s weight.
