Simple routines that catch failures early and make service calls more productive.
A consistent daily walk catches leaks, odors, hot/cold complaints, restroom issues, door problems, abnormal equipment sounds, and safety hazards while they are still small. The value comes from walking the same route and comparing today's building to yesterday's.
Restrooms generate a constant stream of small maintenance problems. A monthly inspection of flushometers, faucets, drains, partitions, accessories, caulk, exhaust, lighting, and hidden leaks catches water waste and user complaints before they become emergencies.
There is no universal 'change every 90 days' rule for commercial HVAC filters. Occupancy, construction dust, filter efficiency, outdoor-air load, runtime, and system design all matter. Build your interval from inspection history and pressure-drop data where available.
A usable PM calendar is simple, equipment-specific, assigned to a person, and tied to recurring work orders. Start with critical assets and common failure points instead of trying to document every component in the building on day one.
A good service call starts with evidence: exact location, symptom, equipment identity, controller readings, error codes, timing, affected areas, and what changed recently. Five minutes of documentation can prevent repeat trips and reduce diagnostic time.
