What are UL (Underwriters Laboratories) Certified/Recognized Products?

When it comes to making a purchase, finding a reliable product is sometimes difficult to recognize. Luckily, UL (Underwriters Laboratories) approved products make that decision simpler, ensuring required standards are met such as safety, sustainability, performance, and quality. In addition, UL certified products must pass testing that is set forth by UL and the IEC (International Electrotechnical Commission).

The UL listed mark on an HVAC unit lets homeowners know that the unit has met the required standards. When a unit is UL certified, it means the components inside are also UL recognized components. This means that the manufacturers of these approved components are inspected at a minimum of four times per year. This ensures the products are being manufactured to the UL standard and the quality of the product hasn’t deteriorated. Nearly 22 billion products annually hold the UL mark. Looking for UL marks and labels when purchasing products ensure a reliable and honest manufactured product.

It is best to make sure that the compressor being replaced in your system holds the UL recognized logo to meet the same standards as the system requirements for UL Certification.

Underwriter Laboratories Mark

“The UL Mark typically consists of the appropriate UL LISTED, CLASSIFIED or CERTIFIED symbol with the corresponding word, a product identification, a control number consisting of the UL file number or 4 alphanumeric characters for Type R Marks, or an issue, lot, or serial number for Type L Marks.” – www.UL.com

The Benefits of UL Certified/Recognized Products

  • The OEM can be assured that the UL recognized or listed components they are installing in their units will perform properly and have been thoroughly tested for endurance and safety outlined by UL and IEC standards.
  • The contractor knows that if a component needs to be replaced, the UL recognized components are designed and tested with integrity in mind to meet the standards stated above.
  • In addition, building inspectors also look for UL marks during inspections to assist approval of the installations, knowing the instruction manuals are reviewed with the equipment.
