Backup Generator Installation FAQs

Common questions about our Backup Generator Installation services

Most residential generator installations take 6-8 hours over one or two days, depending on your home’s setup and permit requirements. We typically install the concrete pad first and let it cure, then return to complete electrical and gas connections. The actual installation time depends on the distance from your electrical panel to the generator location and whether we need to run new gas lines. We coordinate with local inspectors to ensure timely permit approval and final inspection scheduling.
Generator sizing depends on your home’s electrical load and which circuits you want powered during outages. Most homes need between 16-24kW for whole house coverage, but we calculate your specific requirements based on your electrical panel, appliances, and HVAC system. We don’t oversell capacity you don’t need, but we ensure adequate power for essential systems like refrigeration, heating, cooling, and lighting. A proper load calculation prevents overloading and ensures reliable operation during extended outages.
Yes, backup generator installation requires electrical and sometimes building permits in Cook and Will County. We handle all permit applications and coordinate inspections as part of our installation service. Permits ensure your installation meets local safety codes and doesn’t affect your homeowner’s insurance coverage. The permit process typically adds 1-2 weeks to project timeline, but it’s necessary for safe, legal installation. We’re familiar with local requirements and inspector expectations, which speeds up the approval process.
Whole house generator installation typically ranges from $8,000-$15,000 depending on generator size, installation complexity, and site requirements. Factors affecting cost include distance from electrical panel, gas line routing, concrete pad requirements, and permit fees. We provide detailed estimates after evaluating your specific installation needs. While the upfront investment is significant, most homeowners find the peace of mind and avoided outage costs justify the expense, especially after experiencing extended power failures.
Standby generators need annual professional maintenance including oil changes, filter replacement, battery testing, and system inspection. Most units automatically exercise weekly for 15-20 minutes to keep components lubricated and batteries charged. You should check oil levels monthly and keep the area around the generator clear of debris. We offer maintenance service plans that include annual tune-ups and priority service calls. Proper maintenance ensures your generator starts reliably when you need it and extends equipment life significantly.
A properly sized whole house generator can power all your essential systems including HVAC, refrigeration, lighting, and outlets. However, you might need to manage high-draw appliances like electric dryers or pool equipment depending on your generator’s capacity. We design installations to prioritize critical circuits first, then add convenience loads as capacity allows. Most homeowners find they can maintain normal routines during outages with a correctly sized system, though some minor usage adjustments may be needed during peak demand periods.
