What Are Pneumatic HVAC Controls?
Pneumatic HVAC controls use compressed air as the power source to operate and regulate heating, ventilation, and air conditioning (HVAC) systems. These systems have been a trusted standard in commercial and industrial buildings for decades due to their reliability, simplicity, and low operating cost.
Key Components of a pneumatic HVAC system include:
- Pneumatic Thermostats
- Actuators & Positioners
- Relays & Transducers
- Air Compressors & Dryers
- Tubing & Fittings
How Do Pneumatic HVAC Controls Work?
At the heart of the pneumatic system is a compressed air supply. Pneumatic thermostats sense temperature and adjust air pressure signals that control dampers, valves, and actuators throughout the HVAC system.
The air pressure signal typically ranges from 3 to 15 PSI, directly correlating to the control action needed, opening a damper, adjusting a valve, etc.
Common Problems in Pneumatic HVAC Systems and How to Fix Them.

Why Are Pneumatic Systems Still Widely Used?
Even with the rise of digital and Direct Digital Controls Systems, pneumatic controls remain popular in many facilities because:
- They are cost-effective to maintain and repair
- No electrical wiring is needed for control signals
- They are inherently fail-safe
- Many buildings have legacy systems that would cost millions to upgrade
