Air conditioning & ventilation testing, inspection, certification

The air-conditioning and ventilation industry faces strict regulatory requirements regarding safety, energy efficiency, and environmental impact. Manufacturers must ensure compliance with international standards to facilitate smooth market entry. Additionally, customers demand clear and reliable performance data, including sound levels, efficiency metrics, and hygienic design.

If you are a manufacturer of refrigeration systems or heat pumps seeking to place your products on the market, certification by a notified body is mandatory. Without CE marking, market placement is not permitted. According to the European Pressure Equipment Directive (PED) 2014/68/EU, refrigeration systems or heat pumps incorporating pressure equipment classified as category II or higher — such as refrigerant receivers or heat exchangers—are considered assemblies and require the involvement of a notified body during manufacturing.

As a notified body, TÜV SÜD Industrie Service GmbH provides expert support to ensure compliance with EU Directives. Additionally, on-site inspections may be necessary depending on the country of installation, such as in Germany, where the German Industrial Safety Regulation (BetrSichV) applies. Our experts are here to guide you through air conditioning certification and ventilation certification as per regulatory requirements, ensuring a smooth market entry for your products.

Increased focus on air quality and energy efficiency

Indoor air quality and hygiene are increasingly vital post-COVID-19. There’s also more adoption of energy-efficient and environmentally friendly HVAC systems.

Regulatory compliance

Compliance with evolving EU directives, such as Ecodesign Regulations 327/2011, 1253/2014, and 1254/2014, is vital to avoid costly redesigns and market delays.

Technological developments

Integration of smart technology and IoT in HVAC systems for better performance monitoring necessitates up-to-date expertise for inspection and certification.

Global market access

Proper testing to meet stringent energy-efficiency and safety regulations is vital for entry to global markets and competitive differentiation in these markets.

Consumer trust

Businesses can gain trust by meeting expectations for transparent and verified performance metrics such as energy efficiency, sound levels, and hygienic design.

With global reach, TÜV SÜD gives you access to a worldwide network of experts and accredited test facilities. With extensive experience in HVAC systems (from domestic to industrial applications), we can guide you from design phase testing to post-market certification.

Our deep knowledge of diverse regulations such as EU Ecodesign Directives, VDI guidelines, and national standards such as DIN helps you achieve reliable certification, as well as transparent and traceable documentation for market entry.

We enable early identification of design and performance gaps to avoid costly delays. Our tailored solutions for manufacturers ensure alignment with global and local standards for air conditioning certification and ventilation certification.
