Emergency Service and Maintenance


For over 40 years, Ronnie's Generator Service Ltd has been a trusted emergency generator repair contractor in Ontario. We specialize in providing emergency generator services, all generator repairs, and backup power solutions throughout the Greater Toronto Area and beyond. Our expert technicians are available to handle any generator issue you are experiencing and offer preventative maintenance generator contracts for all makes and models.  Contact us today for reliable generator repair and maintenance services in Ontario.


At Ronnies, we repair and service all generator makes and models including generators that are fueled by natural gas, liquid propane gas, or diesel. Our sister company, Paramount Power Systems is an authorized Kohler dealer for the residential and light commercial market and we handle all service, preventative maintenance and any warranty claims on their behalf.  Whether you have a maintenance contract with us or your system is out of warranty, we can provide service, maintenance and repairs as needed.


We also provide maintenance contracts for other brands such as:

Cummins® Onan


MTU/Detroit Diesel




We service virtually any power generators ranging from 20kW to 3200kW.


We meet the stringent maintenance code requirements imposed by the Canadian Standards Association (CSA-C282) for emergency generators used for life safety purposes. The same high standard of customer care is provided to all our residential customers.


Most warranties from Paramount Power Systems are valid for five years.  It is important to maintain your generator regularly during the warranty period and afterwards to keep your system running at peak performance. The maintenance frequency will take into account the type of system and the inherent risks of going without a power source.  If you have an existing Kohler residential generator under warranty, you also have the option to purchase an extended warranty for peace of mind.


Is your backup power generator ready to step in if your primary source should fail during a brownout or blackout? If your answer is "maybe," you should definitely consider regular power generator maintenance. To schedule service, call Ronnie's Generator Service Ltd. today!


Even well-maintained generators can encounter issues that cause them not to start when you need them. Some common generator issues include:

Dead batteries: If the battery is dead or low on charge, your generator won't start.

Fuel:  In some cases, the fuel tanks are empty, or the fuel supply is low or restricted.  Fuel can also break down over time, making it difficult for your generator to start.

Clogged air filters: Air filters can become clogged with dirt and debris, reducing the airflow to the engine and causing starting issues.

Malfunctioning spark plugs: Faulty spark plugs can prevent the engine from starting or cause it to misfire.

Faulty fuel pumps: If the fuel pump is not working correctly, your generator may not start or may stall.


How Much Does Generator Repair Cost?

Repairing your generator will vary in cost depending on the parts required and the time it will take to repair the generator.  If the unit is under warranty and the unit was regularly maintained, the cost to repair it will be much less than a unit that is out of warranty and has not been regularly serviced.

What Causes a Generator To Stop Working?

Generators commonly break down because of the loss of residual magnetism. Generators operate by moving electrical conductors through a magnetic field. Generators need to work properly in order to maintain that residual magnetism. Therefore, often when your Genset has been out of operation for a long time, it may not start up immediately.


We are available 24/7 to help you with any generator emergency you may have.
