The company specializes in manufacturing professional-grade HVAC testing and measurement instruments, including digital manifolds, refrigerant leak detectors, clamp meters, and diagnostic tools used by heating and cooling technicians across Southern California and beyond. With a 4.3-star rating compiled from 66 customer reviews, Fieldpiece has built a reputation among HVAC professionals for producing durable, precision instruments designed to withstand the demands of field service environments.

What distinguishes Fieldpiece from typical tool suppliers is their commitment to supporting technicians throughout the entire product lifecycle. Their website showcases an extensive product catalog featuring the SMAN digital manifold series, A2L-compatible leak detectors for newer refrigerant technologies, and the Job Link wireless probe system. The company operates Fieldpiece University, offering training resources and certification support for HVAC professionals. Their online portal provides product registration, firmware updates, and direct access to user manuals, resources that help contractors stay current with evolving HVAC technology.

Customer testimonials reveal the human side of Fieldpiece's operations. A reviewer named David Scott drove from San Diego to their Orange facility where technicians Chris and Nick repaired his multimeter and refrigerant scale, replacing both out of warranty at no charge. Another customer, Happy Sailor, received a replacement refrigerant scale on the same visit after describing his issue to tech support. These experiences illustrate a service-first approach that keeps professional technicians loyal to the Fieldpiece brand.
