An HVAC inspection checklist is the record a technician completes on a service visit, covering equipment condition, measurements and what needs follow-up. It has 8 items: visit details, system identification, safety and access, indoor equipment, outdoor equipment, system-specific checks, evidence and findings. 5 preparation steps set the scope. Then come 7 indoor checks and the outdoor assessment. 4 equipment attachments cover gas furnaces, electric furnaces, heat pumps and ductless systems. Each finding records the next action. Residential and commercial versions name each covered asset. ENERGY STAR recommends a spring cooling checkup and a fall heating checkup, which means 2 visits a year for a home with both systems.
What are the 8 items on an HVAC inspection checklist?
An HVAC inspection checklist contains 8 record sections that document the authorized visit from identification through findings. Inspection evaluates conditions. Maintenance performs defined upkeep. Repair corrects a fault. Commissioning verifies operation against design and startup requirements.
The PDF previews below show the visit record and gas furnace attachment. The download includes the indoor and outdoor checks, findings record, and separate electric furnace, heat pump and ductless attachments. Fields accept typed entries, and each task has a result selector.
The checklist records visit details, system identification, safety and access, indoor equipment, outdoor equipment, system-specific checks, measurements and evidence, and findings and action. The diagram below groups those eight items into the inspection workflow.
Each task receives one of 5 result states: pass, attention, fail, not tested or not applicable. A reading includes its unit, test conditions and equipment reference. An untested item includes the reason and required follow-up.

What are the 5 steps before an HVAC inspection?
HVAC inspection preparation is a five-step review of scope, hazards, procedures, instruments and access limitations. It establishes the conditions for the authorized service visit.
- Confirm the customer, property, covered equipment and authorized scope.
- Identify hazards and the required controls for each task.
- Review the equipment instructions and service history.
- Verify instrument ratings, calibration and technician qualifications.
- Record inaccessible equipment and tasks outside the approved scope.
Under OSHA 29 CFR 1910.147, covered servicing and maintenance requires hazardous-energy control procedures, employee training and periodic inspections. The technician applies the employer’s procedure where unexpected energization or stored energy creates exposure. Electrical work follows the applicable electrical-safety requirements and task-specific procedure.
HVAC business setup establishes the credentials, insurance and operating processes for field service. The guide to starting an HVAC company article covers that preparation.
What are the 7 indoor HVAC inspection checks?
Indoor HVAC inspection checks are 7 component reviews covering the filter, blower and coils, condensate system, supply and return, ducts, controls and ventilation. Each record identifies the accessible component and the observed condition.
| Check | Observation or record |
|---|---|
| 1. Filter | Type, dimensions, fit, condition and service performed |
| 2. Blower and accessible coils | Visible condition, contamination and equipment-specific findings |
| 3. Condensate system | Drain and pan condition, leakage and authorized functional checks |
| 4. Supply and return | Accessible restrictions and measured airflow context |
| 5. Ducts and insulation | Visible damage, disconnection and deterioration |
| 6. Thermostat and controls | Settings, reported issue and authorized operating checks |
| 7. Ventilation | Installed components, observed condition and access limitations |
Lennox’s static-pressure guidance describes 0.5–0.8 in. w.c. as a common residential design range. The equipment’s published blower data establishes the reference for the inspected system. The record includes total external static pressure, measurement locations, blower setting and the applicable maximum.
ACCA’s A Split in Diagnosis calculates a 16.5°F cooling temperature difference for its example at 85°F outdoor temperature, 75°F entering dry bulb, 67°F entering wet bulb and 1,000 CFM. Manufacturer performance data, indoor humidity and airflow establish the expected split for each inspection. The checklist retains both measured temperatures and those operating conditions.
What are the outdoor HVAC inspection checks?
Outdoor HVAC inspection checks are equipment-condition records for access, mounting, coils, fans, insulation, controls and authorized cooling operation. These seven checks establish the observed outdoor condition and test context.
| Check | Observation or record |
|---|---|
| 1. Access and clearances | Measured clearance and manufacturer requirement |
| 2. Mounting and cabinet | Support, level, visible damage and corrosion |
| 3. Coil condition | Visible debris, damage and airflow obstruction |
| 4. Fan condition | Visible condition and authorized operational observations |
| 5. Line insulation | Coverage, deterioration and exposed sections |
| 6. Electrical and controls | Condition and permitted measurements under the task procedure |
| 7. Cooling operation | Ambient conditions, readings, operating mode and reference data |
ENERGY STAR’s maintenance checklist includes coil condition, refrigerant-charge checks and blower-component assessment. EPA Section 608 requires the applicable certification for regulated refrigerant service, including attaching gauges to measure pressure. The visit record identifies the technician, equipment and readings associated with that work.
A visible condition record identifies its evidence (photographs, component location, measured clearance). An operating assessment records its test procedure and equipment specification. Restricted access or unsuitable test conditions receives a “not tested” status and an explanation.
What are the 4 system-specific HVAC inspection checks?
System-specific HVAC inspection checks are 4 equipment attachments for gas furnaces, electric furnaces, heat pumps and ductless systems. Each attachment records the tasks and references for that equipment type.
| System | Inspection context | Reference recorded |
