Commercial Building Preventive Maintenance Checklist

Preventive maintenance keeps small problems from turning into closed floors and emergency invoices. This checklist groups common commercial building tasks by system and frequency so a new maintenance technician knows what to look at and when. Always follow the manufacturer instructions and your site procedures first.

Before you start: safety basics

1. 1. Wear the right PPE for the task and the space.
2. 2. Isolate energy before opening equipment, using lockout tagout.
3. 3. Check the equipment history in the work order system.
4. 4. Tell occupants when work will affect comfort, water, or power.

Daily checks

1. 1. Walk mechanical rooms and listen for unusual noise or vibration.
2. 2. Look for leaks around pumps, valves, water heaters, and restroom fixtures.
3. 3. Confirm building automation alarms are cleared or assigned.
4. 4. Check exit signs and emergency lighting indicators along your route.
5. 5. Note any hot or cold complaints and their zones.

Weekly checks

1. 1. Inspect rooftop units for loose panels, debris, and belt noise.
2. 2. Check restroom flush valves, faucets, and drains.
3. 3. Test a sample of lighting controls and occupancy sensors.
4. 4. Review open work orders and close finished ones with notes.

Monthly checks

1. 1. Check and replace HVAC filters as scheduled. See routine maintenance for HVAC systems.
2. 2. Inspect belts, pulleys, and motor mounts on air handlers.
3. 3. Clean condensate pans and confirm drains flow.
4. 4. Test sump and sewage ejector pumps where present.
5. 5. Do visual checks on fire extinguishers and record tags.

Quarterly and seasonal checks

1. 1. Clean condenser and evaporator coils. Practice the steps in air conditioner maintenance.
2. 2. Prepare heating equipment before winter. Review gas furnace maintenance and boiler inspection and preventive maintenance.
3. 3. Inspect chillers and cooling equipment before summer with air cooled chiller maintenance.
4. 4. Check roof drains and gutters after storms.
5. 5. Verify thermostat and zone setpoints match the season.

Yearly tasks

1. 1. Coordinate fire alarm, sprinkler, backflow, and elevator inspections with licensed contractors.
2. 2. Review the equipment list and update asset records.
3. 3. Infrared scan of electrical panels by a qualified electrician.
4. 4. Update the preventive maintenance calendar based on last year failures.

Turning the checklist into a habit

A checklist only works when each task becomes a scheduled work order with notes. Our perform preventive maintenance micro skill lets you practice the routine in a safe simulation before working on live equipment.

FAQs

What is preventive maintenance in a commercial building?

Preventive maintenance is scheduled inspection, cleaning, and service done before equipment fails. It reduces emergency calls, extends equipment life, and keeps occupants comfortable.

How often should HVAC filters be changed in a commercial building?

It depends on the filter type, the equipment, and the building. Many sites check filters monthly and replace them on a schedule set by the manufacturer and the building engineer.

Who performs life safety inspections?

Facility technicians often do visual checks, but fire alarm, sprinkler, and elevator inspections are usually performed by licensed contractors on the schedule required by the local authority.

Can I use this checklist as is?

Use it as a starting point. Every building should adjust tasks and frequencies to manufacturer instructions, local codes, and its own equipment list.
