Air Pressure Testing Services
Precision compressed air testing for gas lines, building envelopes, and systems requiring dry testing methods throughout British Columbia.
What is Air Pressure Testing?
Air pressure testing utilizes compressed air instead of water to verify system integrity and detect leaks. This method is essential for applications where water cannot be used, such as gas piping systems, building envelope testing, and systems that must remain dry during verification.
At PressureTesting.ca, we employ calibrated air compressors, precision digital gauges, and specialized monitoring equipment to conduct air pressure tests that meet industry standards including CSA B149 for gas piping and ASTM E779 for building envelope testing. Our certified technicians have decades of experience in compressed air testing methodology.
Air pressure testing is particularly valuable for detecting even minor leaks that could pose safety hazards in gas systems or compromise energy efficiency in building envelopes. The testing process is non-destructive and provides immediate, quantifiable results.

Safety First: Professional Air Testing
Air pressure testing requires specialized knowledge and safety protocols. Compressed air systems can be dangerous if not properly managed. Our certified technicians follow strict safety procedures including proper pressure regulation, use of appropriate gauges, and adherence to CSA and ASTM standards. Never attempt air pressure testing without proper training and equipment.
Air Testing Process & Standards
Gas Line Testing Standards (CSA B149)
Gas piping systems in BC must be tested according to CSA B149 (Natural Gas and Propane Installation Code):
- Test Pressure: 1.5 times working pressure (typically 10-20 PSI for residential gas lines)
- Test Duration: Minimum 30 minutes to 1 hour depending on system size
- Acceptance Criteria: Zero pressure drop - gas systems must hold pressure completely
- Documentation: Test must be witnessed and documented for Technical Safety BC
Building Envelope Testing
Air tightness testing follows ASTM E779 and E1827 standards:
- Blower Door Testing: Measures air changes per hour (ACH) at 50 Pascals
- Target Values: Modern buildings: <2.5 ACH50; Passive House: <0.6 ACH50
- Leak Detection: Uses thermal imaging and smoke testing to locate air leaks
- Energy Efficiency: Required for BC Energy Step Code compliance
Advantages of Air Pressure Testing
Safety Critical for Gas Systems
Essential for detecting gas leaks before system activation. Prevents potentially dangerous gas leaks and ensures compliance with Technical Safety BC requirements.
No Water Damage Risk
Eliminates the risk of water damage to systems, materials, or surrounding areas. Ideal for systems that must remain dry or in occupied buildings.
Rapid Results
Faster depressurization and immediate system availability after testing. No need to drain water or dry the system before commissioning.
Energy Efficiency Verification
Building envelope testing identifies air leakage that increases heating and cooling costs. Essential for BC Energy Step Code compliance and energy efficiency rebates.
