Reliable Plant Maintenance (RPM) is an independent, family-owned commercial and industrial HVAC-R contractor serving the DFW Metroplex and North Texas since 2008. Most vendors send whoever's available for a quick fix — so facilities end up managing the vendor and paying for the same problem twice. RPM works differently: we assign the same skilled technicians to your facility, so they know your equipment and its history, diagnose the real problem instead of patching it, and give you clear options instead of a surprise bill. The result is HVAC that's simply handled — with maintenance, repair, and installation for RTUs, chillers, boilers, cooling towers, DX units, computer-room cooling, and indoor-air-quality systems, backed by proactive programs and 24/7 response, and compliant with OSHA, EPA, and IAQ standards.
