Question 1

Do I need a permit for a standby generator installation in Ontario?

Accepted Answer

In most Ontario municipalities, yes. Standby generators typically require electrical permits and may require building permits depending on size and placement. ESA (Electrical Safety Authority) inspections are often required for larger installations. We handle all permit applications and coordinate inspections as part of our service.

Question 2

What is the ESA and why do I need their approval?

Accepted Answer

The Electrical Safety Authority (ESA) is Ontario's electrical safety regulator. They ensure electrical installations meet the Ontario Electrical Safety Code (OESC). ESA inspection may be required for generator installations to verify code compliance and safety. We coordinate with ESA throughout the process.

Question 3

How long does the permit and installation process take?

Accepted Answer

The complete process typically takes 2-4 weeks from initial consultation to final commissioning. This includes permit applications (1-2 weeks), installation (1-3 days), and inspections. Complex installations or custom electrical work may take longer.

Question 4

Can I install a generator myself to save money?

Accepted Answer

Generator installation requires licensed electrical and gas work in Ontario. DIY installation may violate local codes, void warranties, and create safety hazards. Professional installation ensures code compliance, safety, and proper operation.

Question 5

What size generator do I need for my home?

Accepted Answer

Generator sizing depends on your essential power needs. We perform a detailed load calculation considering your heating system, refrigeration, lighting, and other critical loads. Typical homes need 10-20kW, while larger homes may require 22kW or more.

Question 6

How much does generator installation cost in Ontario?

Accepted Answer

Installation costs vary based on generator size, fuel type, electrical requirements, and site conditions. Basic installations start around $8,000-$12,000, while larger or complex systems can cost $15,000-$25,000+. We provide detailed written quotes with no hidden fees.

Question 7

What fuel types are available for standby generators?

Accepted Answer

The two main options are natural gas and propane (LP). Natural gas is convenient if you have existing service and provides unlimited fuel supply. Propane offers independence from utility connections but requires tank refills. We help you choose the best option for your situation.

Question 8

Do I need TSSA approval for fuel systems?

Accepted Answer

Yes, the Technical Standards & Safety Authority (TSSA) regulates propane and natural gas installations in Ontario. Our TSSA-certified gas technicians ensure all fuel system work meets their requirements and passes inspection.

Question 9

How long will my generator run on propane?

Accepted Answer

Runtime depends on tank size and generator load. A typical 20kW generator on a 500-gallon propane tank will run approximately 40-60 hours at 50% load. We can calculate specific runtime based on your generator size and expected usage.

Question 10

What happens if I run out of propane during an outage?

Accepted Answer

This is why proper sizing and monitoring are important. Many customers install larger tanks or dual tanks for extended runtime. Some areas have emergency propane delivery services. We help design systems with adequate fuel capacity for your needs.

Question 11

Is natural gas or propane better for generators?

Accepted Answer

Both have advantages. Natural gas provides unlimited fuel supply and lower operating costs but requires utility connection. Propane offers fuel independence and works in remote areas but requires tank monitoring and refills. We evaluate your specific situation to recommend the best option.

Question 12

How often should my generator be serviced?

Accepted Answer

Most residential generators should be serviced annually by a qualified technician. Generators that run frequently or operate in harsh conditions may need service every 6 months. Regular maintenance ensures reliable operation and extends equipment life.

Question 13

What happens if I don't maintain my generator?

Accepted Answer

Lack of maintenance can lead to poor performance, failure during outages, shortened equipment life, and warranty voidance. Generators are mechanical devices that need regular service to remain reliable when you need them most.

Question 14

Can I service my generator myself?

Accepted Answer

Basic maintenance like checking oil levels can be done by homeowners, but professional service is recommended. Our technicians have specialized tools, training, and access to parts needed for proper maintenance and diagnostics.

Question 15

How do I know if my generator needs repair?

Accepted Answer

Warning signs include failure to start during weekly exercise, unusual noises, visible leaks, error codes on the control panel, or poor performance during testing. If you notice any of these issues, contact us for diagnostic service.

Question 16

Do you provide emergency service during power outages?

Accepted Answer

Yes, we provide 24/7 emergency service across Ontario. If your generator fails during a power outage, call our emergency line immediately. We prioritize these calls and dispatch technicians as quickly as possible to restore your backup power.

Question 17

What's included in a typical maintenance visit?

Accepted Answer

Standard maintenance includes oil and filter change, battery testing, fuel system inspection, load testing, visual inspection of all components, exercise cycle verification, and a detailed service report with recommendations for any needed repairs or improvements.

Question 18

How quickly does my generator start during an outage?

Accepted Answer

Modern standby generators typically start automatically within 10-20 seconds of detecting a power outage. The transfer switch then connects your home to generator power within another 10-30 seconds, providing nearly seamless backup power.

Question 19

Will my generator power my whole house?

Accepted Answer

This depends on generator size and your electrical needs. Whole-house generators (22kW+) can power most homes completely. Smaller generators may require load management or an automatic transfer switch that prioritizes essential circuits like heat, refrigeration, and lighting.

Question 20

How loud are standby generators?

Accepted Answer

Modern generators are designed to meet municipal noise ordinances. Most operate at 60-70 decibels at 7 meters, similar to normal conversation level. Proper placement and sound enclosures help minimize noise impact on neighbors.

Question 21

Can my generator handle starting large appliances?

Accepted Answer

Yes, properly sized generators can start and run large appliances like air conditioners, heat pumps, and well pumps. We perform load calculations to ensure your generator can handle the starting surge and continuous operation of all connected equipment.

Question 22

What happens when utility power returns?

Accepted Answer

The generator will continue running for a cool-down period (typically 5 minutes), then automatically shut down. The transfer switch reconnects your home to utility power. This transition is automatic and seamless.
