As HVAC/R technologies advance, accurate testing and certification measure performance, safety, and compliance. Tools like airflow meters, leak detectors, and infrared cameras assist professionals in maintaining system integrity and aligning with standards. Trusted certifications from bodies like Intertek and UL Solutions reinforce market readiness.
HVAC/R (heating, ventilation, air conditioning, and refrigeration) systems require precise tools and procedures to ensure efficient operation, safety, and compliance with industry standards. Essential testing equipment includes digital multimeters, infrared cameras, refrigerant leak detectors, airflow meters, and temperature/humidity meters. These tools help diagnose, maintain, and repair HVAC/R systems.
Typical HVAC equipment comprises air conditioners, boilers, chillers, heat pumps, dehumidifiers, humidifiers, radiant systems, and other mechanical heating and cooling devices. They are vital components in modern buildings. Testing, adjusting, and balancing (TAB) is essential for optimal system performance. TAB ensures that HVAC and refrigeration components function efficiently and according to design specifications.
HVAC testing and certification involve evaluating system performance, safety, and energy efficiency to meet regulatory standards. This validates high-quality operation. Common performance testing methods include inspecting airflow and distribution, examining electrical plugs and breakers, checking thermostat settings, and cleaning ducts, vents, and condensers to remove dust and debris.
As smart HVAC/R systems become more prevalent, regulatory compliance presents new challenges. Many companies supply advanced instruments for monitoring parameters like temperature, pressure, and airflow. Furthermore, Intertek and UL Solutions offer testing and certification services, covering system performance, safety, and energy efficiency standards for HVAC/R equipment. Below are insights into randomly selected companies compiled from sources offering testing and certification services.
Intertek Solutions
HVAC equipment testing ensures that it meets the required standards for performance, safety, and energy efficiency. Independent testing laboratories, like Intertek, do this testing. Equipment that meets the required standards is given the ETL certification mark. This indicates that it has been tested and certified. HVAC testing and certification help ensure that HVAC systems and equipment are safe, reliable, and energy-efficient. Market requirements for HVACR equipment are evolving quickly, including standards for safety, energy efficiency, performance, chemicals, IoT, and more. To ensure the most efficient path to product success, manufacturers and stakeholders seek Intertek for the most up-to-date regulatory information and all their assurance, testing, inspection, and certification needs.
UL Solution
UL Solutions provides independent third-party verification to help demonstrate the performance and quality of your HVACR products so they stand out in a crowded marketplace. With UL energy efficiency testing and certification, the company benefits from flexible, localised service from UL Solutions laboratories that conduct tests for international energy efficiency standards for each region. UL Solutions’ expert engineers help HVACR manufacturers meet end-consumer, retailer, and installer expectations and comply with emerging environmental and safety regulations in all HVACR industry segments.
Testo
The Flue Gas Analyser – testo 350 is designed and crafted considering the user’s needs. This instrument is matchless in performance and engineered to perfection. With the testo 350, up to 6 gases can be analyzed simultaneously—the user can choose between the sensors such as O₂, CO, CO₂, NO, NO₂, SO₂, HC, and H₂S. The sensors are easily replaceable by the user in the field without even using any tools. The analyser has features that calculate standard parameters such as flue gas loss, excess air ratio, and boiler efficiency. By connecting additional probes, it measures velocity, differential pressure, and temperature. Its user-friendly on-site calibration program ensures zero downtime. Testo 350 is the ideal solution for flue gas analysis. The Testo 350 is a rugged, easy-to-use exhaust gas analyser designed to meet the highest demands for precise industrial emission measurements and proper data administration.
PCE Instruments
The HVAC tool or a meter is a key aspect of HVAC balancing, testing, and adjusting. During the initial inspection of a commercial or residential building, temperature gauges, such as an HVAC meter, can be verified for proper heating and cooling operation. PCE Instruments pressure and leak detectors quickly detect duct problems and find leaks in refrigeration manifolds. Their multimeters and power analysers assist in identifying possible electrical issues with everything from pumps, compressors, and cooled chillers to igniter and flame sensor wires for a combustion chamber.

Fieldpiece Instruments Inc.
A refrigerant leak detection sensor checks leaks used in air conditioners and refrigerators. The sensor is placed in system parts, such as near cooling pipes, joints, or machines. Fieldpiece’s two newest detectors are raising the bar. The DR82 Infrared Refrigerant Leak Detector and the DR58 Heated Diode Refrigerant Leak Detector bring a higher level of performance and offer new, bright blue backlit LCD screens that are easy to read and understand. They are portable and built to work all day and all night with USB rechargeable batteries that can get 10-18 hours of use per charge. They are designed for the field with rugged, impact- and water-resistant, IP54-certified over-moulded bodies. Each leak detector also comes with a blow-moulded carrying case.
HVAC & Tools Direct
HVAC and refrigeration workers use the Uniweld RHP800 nitrogen regulator to test or clean out systems that use nitrogen gas. It assists in regulating the nitrogen flow and pressure as it exits the tank. For the majority of HVAC operations, such as cleansing lines or checking for leaks, this regulator’s 800 PSI pressure handling capacity is sufficient. It features a 1/4″ male flare outlet. It attaches to most hoses used in HVAC operations and a CGA580 intake, a common connection for nitrogen tanks.
The Uniweld RHP800 helps control the flow and pressure of nitrogen gas for cleaning and testing the systems. Due to the large, clear gauges on the front, technicians can quickly check the output pressure and tank pressure.
It is available either with a classic analogue output or optionally with digital interfaces like Ethernet and RS-485 (Modbus protocol). As a standalone solution, the measured data stored in the optional data logger can be read out via a USB stick and evaluated using the software CS Soft Basic.
