Why Preventative Maintenance Matters
Every hour your vehicle or machine is down costs you time and money — preventative maintenance keeps both in check. By staying ahead of wear, leaks, and failures, you reduce major repair costs, extend asset life, and keep your fleet operating safely and efficiently.
At Simmons Services, we track every interval, inspection, and service performed so you always know the status of your equipment. Whether we’re servicing a single truck or a full fleet, our PM approach is proactive, precise, and built around your operation’s schedule.
