FAQs
Why should I install a residential backup generator in Thorn Hill?
Thorn Hill experiences occasional power outages due to severe weather, grid maintenance, or unforeseen equipment failures. A backup generator automatically restores electricity within seconds, preventing food spoilage, sump-pump failures, frozen pipes in winter, and the inconvenience of living without lights, HVAC, and essential electronics. It adds peace of mind and can increase home resale value.
What size generator do I need for my home?
The correct generator size depends on the circuits and appliances you want to power. A whole-home unit typically ranges from 14 kW to 24 kW for most Thorn Hill residences, while partial-load systems can be as small as 7 kW. Our technicians perform a load calculation that considers HVAC, refrigeration, well or sump pumps, medical devices, and any high-demand appliances to recommend the most economical and reliable option.
How is a standby generator installed and how long does it take?
Installation involves (1) site assessment and permitting; (2) pouring a concrete or composite pad; (3) mounting the generator and automatic transfer switch (ATS); (4) connecting fuel lines (natural gas or propane); and (5) wiring the unit into your home’s electrical panel. Most projects take 1–2 days of on-site work once permits and utility locates are approved, typically within 2–3 weeks from initial consultation.
Do I need a permit or inspection in Thorn Hill?
Yes. York Region and the City of Markham require an Electrical Safety Authority (ESA) notification and inspection for generator wiring. Natural gas hookups must meet TSSA codes, and building permits may be required for exterior installations. As a licensed electrical contractor, we handle all paperwork, inspections, and coordinate with Enbridge or your propane supplier to ensure full compliance.
What fuel options are available and which is best?
Most Thorn Hill homeowners choose natural gas because it provides an unlimited fuel supply through existing utility lines and eliminates refueling. Propane is the preferred alternative where gas service is unavailable; it offers similar reliability but requires an on-site tank that must be kept filled. Gasoline and diesel are less common for residential standby use due to limited storage capacity, odour, and higher maintenance.
How much maintenance does a standby generator require?
Maintenance is straightforward: an annual service visit includes oil and filter changes, spark-plug inspection, battery check, and software diagnostics. The generator runs a self-test for a few minutes each week to keep internal components lubricated. With proper servicing, most units last 15–20 years or 2,000+ operating hours. We offer maintenance plans that satisfy manufacturer warranty requirements and provide priority repair service during outage events.
