Frequently Asked Questions About Whole-Home Generator Installation in Markham
The ideal size (typically 14kW-24kW for residential) depends on your home's square footage, essential appliances, and desired backup coverage. We'll help you determine the right fit during our assessment.
Most installations are completed within 1-3 days, depending on site complexity, fuel line requirements, and electrical panel work. Permitting adds to the overall project timeline.
A standby generator is permanently installed, automatically turns on during outages via an ATS, and runs on natural gas or propane. Portable generators require manual setup, fueling, and extension cords.
Yes, an ESA electrical permit is mandatory for all whole-home generator installations. Additionally, Markham has specific bylaws (like 396-2018) regarding noise and setbacks that must be followed. RenoHouse handles all permitting.
We specialize in installing leading brands such as Generac, Kohler, and Briggs & Stratton, known for their reliability and performance.
A typical turnkey 16kW installation in the GTA ranges from $8,000 to $18,000. Overall project costs can vary from $6,500 to $22,000, with an average around $12,500, depending on various factors.
Standby generators typically require annual maintenance to ensure optimal performance and longevity. This includes oil changes, filter replacements, and system checks.
Most whole-home standby generators are designed to run on either natural gas or liquid propane (LP). We will connect your generator to the appropriate fuel source available at your property.
Yes — newer homes often lack outlets in convenient locations, especially in kitchens, home offices, and garages. We add outlets by running new wiring through walls and ceilings, ensuring every addition meets ESA (Electrical Safety Authority) requirements. USB-integrated outlets are a popular upgrade.
A Level 2 EV charger (240V) installation in a newer suburban home typically costs $800–$2,000 including the dedicated circuit, wiring, and outlet or hardwired connection. Homes with the electrical panel in the garage are at the lower end, while longer wire runs increase cost.
LED pot lights use 75% less energy than halogen, last 25,000+ hours, and provide superior light quality. A full-home LED pot light upgrade (15–25 lights) typically costs $2,000–$4,000 installed and is one of the most impactful lighting improvements you can make.
