Generator Repair in Toronto
PATO Mechanical Services provides generator repair in Toronto for units that will not start, keep shutting down, run rough, lose performance, or stop producing power.
A Running Generator Can Still Have a Problem
Starting the engine is only one part of normal generator operation. Your generator may start but surge, shut down after several minutes, struggle when equipment is connected, or fail to produce electrical output. Those symptoms point to different problems, so we begin with how the generator behaves rather than assuming every issue is engine-related.
Generator Problems We Repair
Your generator can provide useful clues before it stops working completely. Pay attention to what happens during startup, while it runs, and after equipment is connected.
Generator Will Not Start
If your generator refuses to start, tell us what happens and when it last ran normally. Fuel delivery, ignition, airflow, starter components, or another engine-related issue may be involved. We use the symptoms you describe to guide the inspection.
Generator Starts and Then Shuts Down
A generator that starts and stops shortly afterward presents a different problem from one that never starts. Let us know how long it runs, if the shutdown happens under load, and what changes immediately before the engine stops.
Generator Runs Rough or Surges
If the engine speed repeatedly rises and falls, sounds uneven, or struggles to run steadily, tell us when it happens. We look at how the generator behaves both before and after equipment is connected.
Generator Runs but Does Not Produce Power
A generator can have a running engine without providing usable electrical output. If connected equipment is not receiving power, tell us specifically so the electrical-output side of the generator can be considered during inspection.
Generator Loses Performance Under Load
Some generator problems only appear when equipment is connected. The engine may bog down, performance may drop, or the unit may struggle with loads it previously handled. Tell us what was connected and what changed when the problem appeared.
Generator Problems After Storage
Generators can sit unused for long periods before they are needed again. If your unit has been stored for months, tell us when it last ran and what happens now. That history provides useful context before inspection.
Why Choose PATO Mechanical Services for Generator Repair?
15+ Years of Mechanical Experience
PATO Mechanical Services brings more than 15 years of mechanical experience to equipment troubleshooting and repair. That background helps our team consider how the generator's different mechanical systems are working together.
Hands-On Generator Experience
Our mechanical background includes previous work with generators and water pumps, giving PATO Mechanical Services practical experience with equipment designed to operate when reliable mechanical performance matters.
Troubleshooting Based on Your Symptoms
You do not need to diagnose the generator before contacting us. Tell us if it will not start, shuts down, surges, loses performance, or runs without producing power, and we use those symptoms as the starting point.
Drop-Off and Onsite Service Options
Smaller portable generators that can be reasonably transported are generally suited to drop-off service. Larger units that are difficult to move may qualify for an onsite assessment depending on the equipment, location, and problem.
Our 4-Step Generator Repair Process
Tell Us What the Generator Is Doing
Contact PATO Mechanical Services with the make and model, your location, a photo when possible, and a description of the problem. Tell us what happens during startup, while the generator runs, and when equipment is connected.
Answer a Few Initial Questions
We may ask when the generator last worked properly, how long it has been stored, and when the problem appears. These details help us understand the generator's recent history before inspection.
Arrange the Inspection
Smaller generators that can be transported are generally handled through drop-off service. Larger units that are difficult to move may qualify for an onsite assessment based on the equipment, location, and service required.
Review the Findings and Repair
After inspection, we explain what we found, what work is required, and if replacement parts are needed. PATO Mechanical Services can source parts and keep you informed when availability affects the next step.
How Generator Repair Pricing Works
The cost of generator repair depends on the generator, problem, required parts, and work involved. A no-start problem can require very different work from an electrical-output issue, so PATO Mechanical Services does not use one fixed repair price for every generator. If we travel to your location for diagnosis, a $150 service call fee applies. We discuss the fee before the visit, and it is applied toward the repair cost if you proceed.
Generator Repair FAQs
Why Won't My Generator Start After Sitting in Storage?
The generator may not be getting what it needs to start and continue running after a long period of storage. Fuel condition, ignition, airflow, starter components, or another engine-related issue may be involved.
Why Does My Generator Start and Then Shut Down?
The generator can start but is unable to continue running normally. Pay attention to how long it operates and if the shutdown happens only after equipment is connected, because that helps identify when the problem appears.
Why Is My Generator Surging?
Surging means the engine speed repeatedly rises and falls instead of remaining steady. The behaviour may change depending on whether the generator is running by itself or supplying power to connected equipment.
Why Is My Generator Running but Not Producing Power?
The engine and electrical-output side of a generator perform different functions. If the engine runs but connected equipment receives no power, the problem needs to be assessed beyond basic engine operation.
Can I Drop My Generator Off for Repair?
Yes. Smaller generators that can be transported reasonably are generally suited to drop-off service. Contact PATO Mechanical Services first with the make, model, and problem so we can discuss the arrangement.
Do You Provide Onsite Generator Service?
Sometimes. Larger generators that are difficult to transport may qualify for an onsite assessment depending on the equipment, location, and service required. A $150 service call fee applies and is credited toward the repair cost if you proceed.

Toronto is the main service area for our generator repair service. PATO Mechanical Services also regularly serves Scarborough and Vaughan, with other GTA locations available based on the equipment, location, and current availability.

Have Your Generator Checked Before You Need It
If your generator will not start, keeps shutting down, surges, loses performance, or fails to supply power, contact PATO Mechanical Services. Call 647-612-0997 with the make and model, your location, a photo when possible, and a description of what the generator is doing.
