The water that circulates through heating, ventilation, and air conditioning (HVAC) systems plays a pivotal role in maintaining energy efficiency, protecting equipment, and ensuring a healthy indoor environment. From cooling towers and chillers to closed-loop heating systems, the quality of HVAC water can influence corrosion rates, scale formation, and even air quality within a building.

Corrosive conditions, scaling, and biofilm formation impair heat exchange and force systems to work harder, raising energy bills.
Cooling towers and open-loop HVAC systems can harbor Legionella and other microbes, creating serious health risks if not properly monitored. Our CDC ELITE–certified Legionella testing and ASSE 12080–qualified water safety expertise help you detect contamination early and maintain full ASHRAE 188 compliance for safe and efficient system operation.
Corrosion weakens pipes, valves, and heat exchangers. Scale deposits lower system efficiency and can lead to costly repairs or early equipment replacement.
Many jurisdictions and guidelines, such as ASHRAE 188, call for periodic Legionella testing in HVAC systems. Our regulatory compliance services help ensure alignment with local and national health standards.
We maintain the highest standards in environmental compliance and sustainability. Our certifications demonstrate our commitment to responsible practices and regulatory excellence.
Why Test:
Proper pH balance is critical to prevent corrosion and scaling. Alkalinity levels guide water treatment decisions, ensuring optimal chemical dosing to maintain stable conditions.
Why Test:
High TDS can indicate excessive mineral content, which leads to scale buildup, reducing heat transfer efficiency. Conductivity measurements track the overall ionic load and help determine when blowdown or treatment adjustments are needed.
Why Test:
Hard water minerals precipitate as scale on heat exchanger surfaces, increasing energy consumption and wear on equipment. Monitoring hardness supports preventative measures like softening or anti-scale treatments.
Why Test:
Elevated metal concentrations suggest corrosion of pipes or equipment. Early detection enables targeted corrosion inhibition programs, extending the life of costly infrastructure.
Why Test:
Biofilms and bacterial growth reduce heat exchange, raise health risks, and promote corrosion. Routine microbial testing and Legionella screening help maintain safe and hygienic conditions.
Why Test:
Many HVAC systems use chemical treatments—corrosion inhibitors, scale inhibitors, and biocides—to maintain water quality. Measuring their residual levels confirms proper dosing, ensuring conditions remain stable and contamination is minimized.
Maintain comfort and energy efficiency by preventing scale buildup in chillers and ensuring that cooling tower water meets recommended microbial standards.
Hospitals and clinics require Legionella testing and corrosion control to protect patients. Routine microbial screening minimizes risk and supports safety and regulatory compliance.
Improve heat transfer efficiency and system reliability by optimizing the chemical balance in high-stakes cooling systems that protect sensitive equipment from overheating.
Preserve expensive mechanical components by controlling corrosion and scaling in steam and hot water loops critical for process heating and climate control.

Frequency depends on the system and its complexity. Many facility managers test monthly or quarterly, while others opt for continuous monitoring of critical parameters. We can customize a schedule based on your equipment type, local regulations, and operational goals.
While not always mandated by law, many local guidelines and standards—particularly regarding Legionella control—strongly recommend routine testing. Insurance providers and accrediting bodies may also require documentation of water quality management.
Our experts help you respond swiftly and effectively. We can guide you through shock chlorination protocols, system flushes, improved filtration, or the adoption of alternative biocides to restore safe conditions.
Yes. We can present results in formats compatible with building automation systems, enabling real-time data visualization, trend analysis, and proactive alerts for abnormal conditions.
Absolutely. Even closed-loop heating or chilled water systems benefit from monitoring for corrosion, pH shifts, and inhibitor depletion. Early detection helps you maintain equipment efficiency and prevent costly downtime.
