About Us.
Tier 4 Equipment Repairs is a family-owned and operated heavy diesel mobile repair service built on integrity, reliability, and faith. We provide on-site diagnostics, repairs, and preventative maintenance for heavy equipment at construction sites, farms, and job sites—bringing the tools and experience straight to you to minimize downtime and keep your equipment running at its fullest potential.
Founded by Randy, a Brevard, NC native now based in the Upstate with his wife Christina and their son Gavin, Tier 4 was built on the kind of values you can’t fake: show up, do what you say you’ll do, and treat people right. We take pride in quality workmanship, clear communication, and the relationships we build along the way—because when you call Tier 4, you’re not calling a call center, you’re calling a team that treats every customer like family.
