How much does it cost to install a standby generator at home?

Installing a home standby generator is a customized project, so total cost is confirmed after an on-site assessment of your home’s power needs and installation conditions. The biggest driver is generator size (how many circuits or whole-home loads you want to cover), followed by installation complexity. Our team installs and services standby systems throughout the Haverhill area with options for whole-home or essential-circuit coverage. You can also use available financing, and a $250 off home generator installation offer is currently listed; ask about eligibility and conditions. A right-sized system avoids paying for capacity you’ll never use while keeping essentials running during outages.

What typically affects price:

• Power capacity (kW) and whether you choose whole-home or partial coverage
• Transfer switch type and required electrical panel work
• Fuel setup and location, pad/placement, and wiring distances
• Model features and accessibility for service

Schedule an in-home assessment to get an exact proposal and avoid over- or under-sizing. <br/> Updated: 2026-03-14 <br/> Need help in Haverhill, MA? Call (978) 716-5703 or book online.
