Who is this hvac inspection checklist for?
- Facility managers who check rooftop units, split systems, or air handlers between contractor visits
- Building maintenance staff who clean filters and want a record of each unit
- Store and office managers who need to show when a unit was last checked and what was found
When to use it
Use one sheet per inspection visit. Many buildings do this check monthly or quarterly, and before the cooling and heating seasons start. If you have several units, write the unit ID on each row, or use one sheet per unit.
What's included
The template includes the following. Delete anything you do not need.
- Header for building or location, inspection date, and inspector
- Indoor unit: filter, drain pan and condensate line, supply air temperature, noise, panels, blower belt
- Outdoor unit: clearance, condenser coil, fan, line insulation, pad and isolators, disconnect
- Refrigerant and piping: leak signs, corrosion, and a reminder about leak checks by a certified technician
- Controls: thermostat, set points, schedules, error history, and a thermometer check, plus 2 blank rows
- Unit ID and reading columns, Pass / Fail / N/A drop-down, and a defect record
- A filled-in sample sheet and a print layout for US Letter

| 7 | ■ Sheets in this workbook |
| 8 | "Entry Sheet" … The sheet you fill in on a computer. Landscape layout. |
| 9 | "Sample (Filled In)" … A filled-in example. Use it as a guide to how each column is written. |
| 10 | "Print (Letter)" … For printing and filling in by hand. Taller rows, and the column headings repeat at the top of every page. Set up for US Letter. |
| 11 | |
| 12 | ■ How to use |
| 13 | 1. Fill in the building, date, and your name at the top. |
| 14 | 2. For each item, write the unit ID and mark Pass, Fail, or N/A. Write the reading if you measured something (for example supply 56°F, return 74°F). |
| 15 | 3. For each Fail, write what you found and what you did in the findings column. |
| 16 | 4. If the unit needs a contractor, write it in the defect record with who you reported it to and when. |
| 17 | 5. Write the next inspection date and any change in schedule in the summary, then save the file with the date. |
| 18 | |
| 19 | ■ How to mark results, and what to do (read before you start) |
| 20 | Pass … OK to use. |
| 21 | Fail … Stop using it on the spot and tag it "Do Not Use" or barricade the area. Tell your supervisor and write the corrective action. |
| 22 | N/A … The item does not exist here or does not apply today. Do not leave it blank. A blank cell means "not checked". |
| 23 | The inspector may decide to stop. Nobody is blamed for stopping. If in doubt, mark Fail. |
| 24 | After the corrective action, do not return it to service until the verifier writes the re-check date and name. |
| 25 | |
| 26 | ■ Adapting it to your site |
| 27 | • Delete rows that do not apply, such as the blower belt on direct-drive units or the outdoor unit for a water-cooled system. |
| 28 | • Add rows for your equipment, such as economizer dampers, a humidifier, a boiler, or a cooling tower. |
| 29 | • If you track many units, add one row per unit for the filter check and keep the other items per visit. |
| 30 | |
| 31 | ■ Things to watch |
| 32 | • This is a general inspection template, not a manufacturer service checklist or an official form. Follow the manufacturer's maintenance instructions for each unit. |
| 33 | • Work on refrigerant circuits, gas piping, and electrical parts should be done by a qualified, certified HVAC technician. |
| 34 | • Turn off power at the disconnect before opening panels or cleaning coils, and follow your lockout procedure. |
| 35 | • Rules on refrigerant leak checks and records depend on the refrigerant and the size of the system. Ask your HVAC contractor which apply to your units. |

How to use the hvac inspection checklist
- Fill in the building, date, and your name at the top.
- For each item, write the unit ID and mark Pass, Fail, or N/A. Write the reading if you measured something (for example supply 56°F, return 74°F).
- For each Fail, write what you found and what you did in the findings column.
- If the unit needs a contractor, write it in the defect record with who you reported it to and when.
- Write the next inspection date and any change in schedule in the summary, then save the file with the date.
Adapting it to your site
- Delete rows that do not apply, such as the blower belt on direct-drive units or the outdoor unit for a water-cooled system.
- Add rows for your equipment, such as economizer dampers, a humidifier, a boiler, or a cooling tower.
- If you track many units, add one row per unit for the filter check and keep the other items per visit.
Before you use it
Please read
- This is a general inspection template, not a manufacturer service checklist or an official form. Follow the manufacturer's maintenance instructions for each unit.
- Work on refrigerant circuits, gas piping, and electrical parts should be done by a qualified, certified HVAC technician.
- Turn off power at the disconnect before opening panels or cleaning coils, and follow your lockout procedure.
- Rules on refrigerant leak checks and records depend on the refrigerant and the size of the system. Ask your HVAC contractor which apply to your units.

HVAC Inspection Checklist FAQ
What is included in an HVAC inspection?
A routine HVAC inspection usually covers filters, the drain pan and condensate line, coils, fans and belts, refrigerant line condition, electrical connections, and controls. This checklist groups 20 such items for indoor units, outdoor units, piping, and controls.
How often should HVAC be inspected?
Many facilities check filters monthly and do a fuller check each quarter, with a contractor service before the cooling and heating seasons. Follow the manufacturer's schedule and adjust for dust and run hours at your site.
What is the difference between an HVAC inspection checklist and an HVAC maintenance checklist?
An inspection checklist records what you looked at and what you found. A maintenance checklist lists the work done, such as filter changes or coil cleaning. This template does both: mark the result and write the action taken in the findings column.
What supply air temperature is normal?
It depends on the system. In cooling mode, many technicians look for a split of about 15 to 20°F between return and supply air. Check the manufacturer's data for your unit.
