How Often Should You Perform Glycol Testing? Expert Guidelines
Maintaining a glycol-based HVAC system requires more than just initial installation and setup. Regular glycol testing is essential to ensure your heating and cooling systems operate efficiently, remain protected from freezing, and avoid costly equipment damage. But how often should you actually test your glycol? This guide provides expert recommendations to keep your system running optimally. Why Glycol Testing Frequency Matters Unlike "set it and forget it" systems, glycol solutions degrade over time. Heat, oxygen exposure, and stagnant conditions break down the fluid, forming organic acids that lower pH and corrode system components. Without regular glycol testing, you're operating blind—unaware of concentration levels, inhibitor depletion, or contamination that could lead to catastrophic system failure. The consequences of neglecting glycol testing include: Frozen pipes due to insufficient glycol concentration Corrosion damage from depleted inhibitors Equipme...
