Service
Building on years of experience with load-based testing (LBT), we partner with leading heating, ventilation and air conditioning (HVACR) manufacturers to pilot controls verification procedure (CVP) methodologies and provide feedback that helps shape the approach to testing.
The potential for improved energy efficiency grows as HVACR systems incorporate variable-speed compressors and fan motors. Traditional performance testing methods rely on static conditions and fail to measure how these systems operate under real-world scenarios.
The CVP is a testing methodology developed to assess whether HVACR equipment can function as intended under its native control algorithms during regulatory testing. By allowing systems to run dynamically, CVP confirms that variable-speed units perform across different load conditions.
UL Solutions conducts CVP testing in alignment with guidance provided by AHRI, helping manufacturers meet evolving industry expectations. While AHRI is the official certification body accredited to ISO 17065 and responsible for listing products in the AHRI Directory, UL Solutions supports this process by issuing ISO 17025-accredited test reports.
As an independent third-party laboratory, we help manufacturers validate performance, refine controls and prepare for certification with confidence. This collaborative approach supports consistency and transparency across the HVAC industry.
Our CVP testing services extend beyond certification support. We also offer:
Our experts are ready to help you pursue certification from AHRI with confidence, so you can demonstrate that your HVACR systems perform as expected under real-world conditions. Let us know how we can help you build confidence and bring your products to the market.
*Within UL Solutions we provide a broad portfolio of offerings to many industries. This includes certification, testing, inspection, assessment, verification and consulting services. In order to protect and prevent any conflict of interest, perception of conflict of interest and protection of both our brand and our customers brands, UL Solutions has processes in place to identify and manage any potential conflicts of interest and maintain the impartiality of our conformity assessment services.
Dynamic load-based testing (LBT) simulates a building’s heating and cooling demands, providing insights into system performance and efficiency.
