Why Johnson Air Rotation?
American built HVAC systems that perform!
- Cost Savings
- Johnson Air-Rotation HVAC eliminates much of the infrastructure needed for more conventional systems.
- Maintenance Reduction
- Grade mounted, vertical air handlers are maintained from ground level, making maintenance easy.
- Efficiency
- Johnson introduces conditioned air near the roof deck that returns at the ground and uses efficient prop fans.
- Consistency
- In many applications, temperature and humidity design criteria are critical, meaning consistency is a must.
- Extended Product Life
- Higher quality construction and components results in a product lifespan of 30+ years versus 10-15 for rooftop units.
