Generator installation, from someone who's done it before.
Whole house generator installation hides behind a dozen other job titles: electrician, HVAC shop, propane dealer. We checked installer websites in 50 states (9,020 listings) for real standby and whole-home generator experience, whatever brand they work with, and kept the list independent. No broker layer, no lead resale. Just a better place to start.
6,698 installers nationwide with a dedicated generator page on their site.
6531 dedicated, 685 repeated, 1804 signal across the live directory.
Website signal is a starting filter, not a license check, not an endorsement.

Whole-house install or ongoing service?
Narrow the national directory by standby / whole-house signal or by shops with service and maintenance language in reviews.
Already know the brand?
The directory is brand-agnostic. Generac buyers often search for dealers, installers, or service. That hub covers all three from website signal.
Read before you request quotes
Cost, sizing, and the first-call questions, written from primary sources, not installer blogs.
Whole-house generator cost
What a finished standby project actually costs: equipment vs labor, air-cooled vs liquid-cooled, and why two quotes on the same unit can differ by thousands.
What size generator do you need?
Skip the square-footage rule of thumb. Load calculations, locked-rotor amps, and when load management lets a smaller unit cover the house.
Questions to ask a generator installer
A first-call checklist: licenses, fuel work, load calc, permits, warranty path, and the red flags that show up in real complaints.

Not an endorsement. A better place to start.
Common questions
- How does GeneratorInstallerList decide who makes the list?
- We cast a wide net, then check installer websites ourselves. A company stays on the list when their own site shows standby or whole-house generator signal: a dedicated page, repeated mentions, or at least one clear mention worth a first call. That is website signal, not a license check or endorsement.
- What is a dedicated generator page?
- A page on the installer’s own website about standby or whole-home generator work. It is the strongest website signal we track. You still need to verify licensing, insurance, references, and scope yourself.
- Does it matter which generator brand I want?
- No. Generac, Kohler, Cummins, Briggs & Stratton, whatever you have in mind, this directory is not tied to one manufacturer. We filter installer websites for real standby generator signal regardless of brand, then let you narrow by brand if you already have a preference.
- Where should I search if I want installers near me?
- Use the Near Me page for ZIP distance sorting. Standby crews often cover a wide radius, so a state or metro list is usually more useful than a single city name.
- What should I ask before requesting a quote?
- Ask who holds the electrical and gas licenses, how they size the unit, what the quote includes, who pulls permits, and how warranty service works. Use our questions-to-ask guide for a full checklist.
- I am an installer. How do I get listed or correct an entry?
- Open the For Installers page and send the correction or the URL that shows your standby generator work. Include enough detail for us to match the right listing.
