Ottawa’s harsh winters and frequent power outages make a home backup generator less of a luxury and more of a necessity. Beyond keeping the lights on, a generator ensures your sump pump keeps running, prevents frozen pipes, and protects your home office from costly downtime.
If you’re considering investing in a generator, here’s what every Ottawa homeowner should know before buying.
Choosing the Right Generator Features
Don’t get distracted by marketing jargon. Instead, focus on:
- Automatic transfer switches – seamlessly power your home when the grid fails.
- Noise ratings – quieter models keep neighbours happy and comply with Ottawa’s by-laws on generator placement.
- Fuel efficiency – compare propane vs. natural gas generators to decide what’s easiest to source in Ottawa.
Understanding Costs Upfront
Backup generators aren’t a one-time purchase. Homeowners must budget for:
- Installation fees – costs vary by neighbourhood and electrical setup. Learn more in our guide: Backup Generator Installation Cost in Ottawa.
- Fuel costs – propane often has higher upfront costs, while natural gas can save long term.
- Maintenance – routine service ensures compliance with Ottawa’s electrical safety inspections.
Warranty and Maintenance in Ottawa’s Climate
Harsh winters can put extra strain on generators. When comparing models, look for:
- Cold-weather kits – essential for reliable starts in sub-zero temperatures.
- Long-term warranties – prioritize brands that cover major components for at least 5 years.
- Local electricians – trusted experts like Electricians Ottawa can handle ongoing service and emergency repairs.
