Generator Installation in Concord, NH
Concord, New Hampshire generator installers serve the state capital region where Eversource and New Hampshire Electric Cooperative outages from ice storms, severe winter storms, and the occasional summer thunderstorm drive steady demand for whole-home standby generators. Generac, Kohler, and Cummins dominate the residential market, with most installs using 18-26 kW air-cooled units running on natural gas (where Liberty Utilities serves) or propane (most surrounding areas). Concord and surrounding town permits cover electrical, gas, and mechanical work, with transfer switch installation requiring a New Hampshire-licensed electrician. Typical turn-key installs run $9,000-18,000 including unit, transfer switch, gas/propane line work, concrete pad, and permit fees.
Concord-area outages from ice storms can run 5-7 days during severe events, making whole-home generators particularly valuable. Most installations run on propane given limited natural gas availability outside the immediate downtown area. Propane sizing requires a 500-1,000 gallon tank to support extended-duration outages, often replacing existing 250-gallon tanks for heating-only use.
Frequently Asked Questions
- Should I use natural gas or propane for a Concord generator?
- If Liberty Utilities natural gas is available at your address, it's usually the simpler choice—no tank refills disrupted by storms. Most Concord-area homes outside downtown run on propane and need 500-1,000 gallon tanks for extended generator operation. Reputable installers coordinate tank sizing with propane suppliers (Eastern Propane, AmeriGas).
- How long does a Concord generator install take?
- A typical 22 kW Generac install takes 1-2 days: pad placement, gas/propane line tie-in, electrical service wiring, transfer switch installation, and commissioning. Permit inspection adds another 1-2 weeks before the unit is fully operational. Many installers schedule installs 4-8 weeks out during peak storm season.
- What size generator does a Concord home need?
- A 14-18 kW unit handles essential circuits (HVAC, kitchen, well pump). 22-26 kW handles a typical 2,500-3,500 sq ft home with central AC, electric oven, and other major loads. Whole-home coverage requires load calculations the installer performs based on your service panel and lifestyle.
