Generac Generator Installation in West Palm Beach, FL
Generac builds the most common home standby generators in South Florida, which means most of the backup power questions we get start with a Generac quote in hand. We install them, we service them, and we'll tell you honestly whether the model you were quoted is the right size for your house. Nassif Electric has handled backup power across South Florida since 1976. As a Florida statewide licensed unlimited electrical contractor (License EC13001410), we size the system, install the generator and automatic transfer switch, pull the permits, and maintain it afterward. Call 561-582-2600 for a free assessment and one written price for your Generac generator installation.
Who Installs Generac Generators in West Palm Beach?
Three kinds of companies install them: generator-only dealers, big-box retailers who subcontract the work, and licensed electrical contractors like us. The equipment is the same. What differs is who sizes it, who pulls the permit, who does the electrical work, and who comes out when it won’t start during a storm.
We handle all four. We also service Generac units installed by other companies, which matters when the original installer is backed up for weeks after a hurricane.
Generac Home Standby Models We Install
Size | Typical use in South Florida | Covers |
|---|---|---|
10–14 kW | Smaller homes, essential circuits | Fridge, lights, outlets, one AC zone, internet |
18–22 kW | Most 2,000–2,800 sq ft homes | Central AC, kitchen, laundry, pool pump (with load management) |
24–26 kW | Larger homes, two AC systems | Whole-home coverage with less load shedding |
32 kW and up | Estates, light commercial | Full load, sometimes three-phase |
Generac’s air-cooled Guardian units cover most of the residential range, with liquid-cooled models above that. Sizes jump in steps, and the honest answer is often that load management lets a 22 kW do what people assume needs a 26 kW — which saves several thousand dollars and some yard space. We run the load calculation before recommending a model, rather than quoting whatever is in stock.
What Does Generac Installation Cost?
Generac states that installation costs for a home standby generator range from $8,000 to $16,000 including the generator. In Palm Beach County, that holds for most homes, with propane sites and flood-zone platforms at the higher end.
System | Typical installed range* |
|---|---|
14–18 kW air-cooled | $9,000 – $13,000 |
20–22 kW air-cooled (most common) | $12,000 – $17,000 |
24–26 kW air-cooled | $16,000 – $22,000 |
32 kW and above | $22,000 – $35,000+ |
Propane tank, pad and gas piping | Added; depends on tank size and placement |
Annual maintenance plan | Quoted per system |
*Estimates for planning only. Your price comes from a site visit and a load calculation.
What changes the number: model and size, natural gas versus propane, the distance from the unit to your panel and fuel source, the pad or platform, whether your electrical service needs upgrading, permits, and any screening your HOA requires.
What a Proper Generac Installation Includes
- Load calculation and model selection, with load management where it saves you a size.
- Permits — electrical and gas, plus structural review for the pad and anchoring, and HOA documentation.
- Site prep: a level concrete pad or engineered platform, anchored for Florida wind loads, with the manufacturer’s clearances from windows, doors and vents.
- Automatic transfer switch installed at your main panel, sized to the service, so the generator can never back-feed FPL’s lines.
- Fuel connection: correctly sized gas line with an exterior shutoff, or an LP tank sized for the runtime you want.
- Electrical connections, battery, and grounding, all terminated to specification.
- Startup and commissioning: fuel pressure checks, simulated outage test, exercise schedule set, and Mobile Link monitoring connected so you and we can see the unit’s status remotely.
- Inspection and registration: we meet the inspectors, close the permit, and register the unit for warranty.
Most installations take one to three days on site, with permits and equipment availability setting the overall schedule.
Generac Service, Repair & Maintenance
A standby generator is an engine that sits outside in salt air and runs a few minutes a week. Ours is the number we want you to call when it stops doing that.
- Annual or semi-annual maintenance: oil and filter, spark plugs, air filter, battery test, coolant where applicable, fuel pressure, enclosure and connection inspection, plus a load test.
- Repairs: units that won’t start, won’t transfer, throw controller faults, or fail their weekly exercise.
- Batteries, which are the single most common reason a generator doesn’t start when the power goes out.
- Units installed by others: we service them too, including when your original installer is booked out after a storm.
Book maintenance before June. Once hurricane season starts, every service company in the county is triaging emergencies.
Generac Warranty — What Actually Matters
Generac covers its home standby units with a limited warranty whose length depends on the model and whether an extension was purchased. Two practical points: the unit has to be installed per the manufacturer’s instructions and registered, and warranty terms generally cover the equipment, not the labor or the electrical work around it. We install to the manual, register the unit, and keep the documentation. Check the current terms for the specific model on your quote — Generac updates them.

Frequently Asked Questions
Generac puts typical installed cost at $8,000 to $16,000 including the generator. In Palm Beach County, a 20–22 kW system usually runs $12,000 to $17,000 installed, with propane tanks, flood-zone platforms, or service upgrades adding to it.
In South Florida, usually 18–22 kW, because central air conditioning drives the sizing rather than square footage. With load management or a soft-start on the AC, a smaller unit can often cover the same home. We confirm with a load calculation.
We strongly advise against it. The installation involves a high-amperage connection at your main panel, a gas or propane line, a permitted pad with wind-load anchoring, and inspections. DIY work also creates problems with insurance and with warranty coverage.
Generator dealers, big-box subcontractors, and licensed electrical contractors all do. We are a licensed electrical contractor serving West Palm Beach and Palm Beach County, and we both install Generac units and service units installed by others.
Yes. We maintain and repair existing Generac units regardless of who installed them, including emergency service during outages.
One to three days on site for most homes. The bigger variables are permit approval and equipment availability — lead times stretch during and after hurricane season, which is why we recommend ordering in the off-season.
At least an annual service: oil and filter, plugs, air filter, battery test, fuel pressure check, and a load test. Coastal homes benefit from twice a year because of salt-air corrosion. Batteries are the most common failure.
Generally not for a typical home. Narrow exceptions exist, such as documented medical necessity or business use of a property. Google sometimes pairs this with questions about unrelated federal tax changes — those are not generator incentives. Ask a tax professional about your situation.
Some insurers offer a small credit for permanently installed, properly permitted backup power, but it varies by carrier and is rarely large. Ask your agent, and make sure your installation is permitted and inspected either way.
Natural gas if your street has service: no tank, no refills, and supply usually continues during storms. Propane where there is no gas main, with the tank sized for the runtime you want. We confirm what’s available at your address before quoting.
