Replacement options
Replace only what the system needs
The cheapest component is not always the lowest-cost outcome. We assess the condition and compatibility of the complete fan assembly before recommending an option.
02
Motor and impeller
Used when the drive assembly or impeller is damaged, incompatible, unbalanced or no longer economical to retain.
- Matched components
- Rotation verification
- Clearance checks
- Vibration assessment
03
Complete fan replacement
Recommended when the assembly is deteriorated, obsolete, incorrectly sized or requires extensive rectification.
- Fan selection
- Mounting modifications
- Weatherproof connection
- Final testing
Repair or replace?
How we choose the practical option
| Assessment | Motor replacement may suit | Complete fan replacement may suit |
|---|---|---|
| Fan condition | Housing and impeller remain sound | Corrosion, damage or multiple worn components |
| Parts | Compatible motor is readily available | Original components are obsolete or mismatched |
| Performance | Fan previously delivered suitable extraction | Fan is undersized, inefficient or poorly selected |
| Controls | Existing starter or VFD is suitable | Controls also require redesign or replacement |
| Value | Isolated failure with serviceable equipment | Repair cost approaches the value of a new assembly |
Our process
From diagnosis to tested replacement
STEP 01
Inspect and identify
We record the motor, fan, electrical supply, controls and site-access requirements.
STEP 02
Recommend options
You receive the practical replacement options, scope and pricing before work proceeds.
STEP 03
Supply and install
The approved equipment is installed, connected and configured for the application.
STEP 04
Test and hand over
Rotation, operation, controls and obvious vibration or airflow issues are checked.
Technical scope
The motor must match the system
Correct replacement involves more than matching the kilowatt number on a nameplate. Speed, phase, mounting, enclosure, duty, controls and fan performance all matter.
- Motor power and speed
- Single or three phase
- Mounting arrangement
- Impeller compatibility
- DOL starter suitability
- Roof isolator condition
- VFD compatibility
- Rotation and operation

Frequently asked
Before replacing an exhaust fan or motor
Should I replace the motor or the complete fan?
Motor-only replacement may suit when the housing, impeller, bearings and supporting components remain serviceable. Complete replacement can provide better value when several components are deteriorated, obsolete or incorrectly sized.
Is the callout fee waived if the motor replacement proceeds?
Yes. The standard callout fee is waived when an approved motor replacement proceeds.
Can you replace single-phase and three-phase motors?
Yes. We work with both single-phase and three-phase commercial kitchen exhaust equipment, subject to site conditions and equipment availability.
Can you install a VFD with the replacement motor?
Where the motor and system are suitable, we can supply and program a correctly selected VFD for controlled starting, speed adjustment and system integration.
How quickly can replacement equipment be installed?
Timing depends on equipment availability, motor size, access and required modifications. We confirm the expected timing with the replacement scope.
Do you replace complete roof-mounted exhaust fans?
Yes. We replace motors, motor and impeller assemblies, and complete roof-mounted or inline commercial kitchen exhaust fans.
