A commercial site is a list of assets, and a maintenance checklist that treats them all the same is a checklist that misses things. The rooftop unit needs its belts, filters, economizer and condensate checked; the split system needs its coils and charge; the exhaust fan needs its bearings and belt; the controls need their setpoints and schedules verified. This page is for the owner or service manager of a US HVAC contracting business building the commercial HVAC maintenance checklist per asset type, and it sets out what the printable checklist has to record so the visit produces a report the property manager will renew on. The maintenance checklist tool on this site produces the checklist per unit type from your own task list.
The asset list comes before the HVAC maintenance checklist template
Before the checklist, the site's equipment has to be tagged and listed: each unit with its location, model, serial, tonnage, refrigerant, filter sizes and belt sizes. The checklist is then generated per asset from its type, so the technician arrives with the right filters and belts and records against the right tag. A commercial HVAC preventive maintenance checklist PDF without asset tags produces a report nobody can act on.
The rtu maintenance checklist PDF
For each rooftop unit: filters replaced and sizes confirmed; belts inspected and tensioned or replaced; blower and motor checked and amperage recorded; condenser and evaporator coils inspected and cleaned as needed; refrigerant charge checked by superheat or subcooling and recorded; economizer damper and linkage operated; condensate drain cleared and trap checked; electrical connections tightened and contactors inspected; controls and thermostat schedule verified; cabinet, curb and roof penetrations inspected; readings before and after recorded; deficiencies listed with a recommended repair.
Splits, exhaust and controls
Split systems add the indoor coil, the blower wheel and the lineset insulation. Exhaust fans are bearings, belts, dampers and airflow. Controls visits verify setpoints, schedules, sensor calibration and alarm history. Each asset type gets its own task list so the HVAC maintenance checklist template stays honest about what was actually done.
Readings, not ticks
A checklist of tick boxes proves presence; a checklist of readings proves work. Record the amperage, the temperatures, the pressures and the static where they apply, before and after. The readings are what the next visit compares against and what defends the contractor when a unit fails between visits.
From the checklist to the report and the repair
Every deficiency on the checklist should become a priced recommendation on the report the property manager receives after the visit, and every accepted recommendation should become a work order against the same asset. That flow is the return on the maintenance contract. The free checklist tool produces the per-unit list; the paid product keeps it against the asset with its history.
Questions people ask about commercial hvac maintenance checklist
Where can I get a commercial HVAC maintenance checklist PDF?
Build it from your own task list per asset type with the checklist tool on this site and print it, or keep it on the phone. A downloaded generic checklist is a starting point for tasks, never for the asset list.
How often should commercial units be maintained?
Quarterly is common for rooftop units, with filter changes more often where the environment demands. The contract should state the frequency per asset type.
Should a commercial HVAC preventive maintenance checklist PDF include readings on every visit?
Yes. Readings recorded against the asset are the history that lets you show the property manager a unit is failing before it fails.
