Questions & answers
How much does a home backup generator cost?
“A partial-home generator covering essential circuits starts around $10,000 installed. A whole-home standby generator that powers your entire panel typically starts around $14,000 installed. Costs vary based on generator size, fuel type, electrical complexity, and permitting requirements. Every project begins with a free on-site consultation so we can provide an accurate quote with no surprises.”
How do backup generators work?
“A standby generator monitors your utility power continuously. When it detects an outage, an automatic transfer switch disconnects your home from the grid and starts the generator within 10 to 30 seconds. It runs on natural gas or propane, powering your home until utility power is restored — then it shuts down automatically. No manual intervention required.”
Where should the generator be placed?
“The unit must be at least 5 feet from windows, doors, and fresh air intakes, and at least 18 inches from exterior walls. We recommend a level concrete pad in an accessible location. Our installation team handles all placement planning, permitting, and code compliance.”
How often should load bank testing be performed?
“NFPA 110 requires annual load testing for emergency power systems. Many facility managers choose semi-annual or quarterly testing for additional assurance. For diesel generators that rarely run under significant load, we recommend at least annual load bank testing to prevent wet stacking and verify performance.”
How much does load bank testing cost?
“The cost depends on generator size, location, and testing duration. Residential load bank tests typically range from $500 to $1,000. Commercial and industrial tests range from $1,000 to $3,000+. We provide detailed quotes before scheduling. Maintenance program customers receive discounted load testing rates.”
How long does a load bank test take?
“A complete load bank test typically takes two to four hours, including setup, warm-up, incremental load steps, sustained full-load running, cool-down, and documentation. Larger generators and extended-duration tests may take longer. We coordinate scheduling to minimize disruption to your operations.”
How often should I have my generator serviced?
“Most manufacturers recommend annual maintenance for residential generators and semi-annual or quarterly service for commercial units. If your generator runs frequently — during outage-prone seasons or for regular testing — you may need more frequent service. We will recommend the right schedule during your first visit.”
How much does a maintenance visit cost?
“Annual maintenance on a residential air-cooled standby generator starts at $695 per visit. Larger liquid-cooled residential units start at $895 per visit. Commercial generator maintenance ranges from $1,200 to $3,000+ per visit depending on unit size and compliance requirements. Our maintenance programs offer predictable pricing and priority scheduling at a lower per-visit cost than one-off service calls.”
Can I do generator maintenance myself?
“You can perform basic tasks like checking oil level, inspecting the enclosure for debris, and verifying that the battery charger light is on. However, oil changes, coolant service, battery load testing, transfer switch operation, and electrical checks require trained technicians with proper tools and diagnostic equipment. DIY work on electrical systems can be dangerous and may void your warranty.”
