Why this directory was built

A standby generator install crosses trades: there's electrical work, often a fuel line to run, and the contractor needs to be licensed for every part of the job. Efficient hiring starts with knowing which companies really do this work. That's what this directory is for: we find the companies, read what each one says about itself, and publish the classification.

How this directory is built

1. Discover. Broad web-search sweeps across a state's metros, county seats, and rural anchor towns surface candidate installer websites. Aggregators, marketplaces, and lead-gen sites are filtered out.
2. Read. We fetch each company's own website: the homepage plus its generator, service-area, and about pages.
3. Classify. Each company is classified from that text: does it actually do standby-generator work, which brands does it install versus service, what services does it offer, and where does it say it works. Companies that don't do generator work are dropped.
4. Normalize. Self-stated service areas are checked against the Census gazetteer so county and town pages reflect real, in-state places.

What the tiers mean

• Generator specialist: Standby generators are the core business — sales, installation, and service.
• Authorized dealer: A factory-authorized dealer for one or more generator brands, typically handling warranty service.
• Electrical contractor: An electrical contractor that installs standby generators alongside general electrical work.
• HVAC / plumbing contractor: An HVAC or plumbing company that installs standby generators alongside its main trade.

No bias

We think the most useful directories are the neutral ones:

• For homeowners: we don't bias one listing over another. We take no money from a company to place it higher, feature it, or give it any edge in the roster. Every company sorts the same way, by tier then alphabetically, whether it has claimed its listing or not.
• For installers: we don't charge for visibility. We only get paid when we hand a company a real lead, and it's a 1:1 hand-off: one homeowner to one company, never a request fanned out to several bidders at once.

Claiming a listing

A company can claim its listing, and claiming is free. Once we verify that a real representative of the business made the claim:

• The listing shows a small "Owner verified" badge next to its name, a signal to homeowners that the company is paying attention.
• Its profile page gains a "Request a Quote" button in the upper-right corner. When a homeowner uses it, we create a contact request and pass it on to the company.
• We charge the company $100 for each lead we send it.

Claiming changes none of the company's public information (phone number, services, and service area are already shown for every listing), and it buys no placement advantage.

What we don't vouch for

Everything on a listing (brands, service areas, dealer status, license numbers) is what the company says about itself on its own website, read and classified by us. We're not affiliated with any manufacturer. Before hiring, verify the contractor's electrical license with the state and confirm dealer status with the manufacturer if warranty coverage matters to you.
