The 16 line items a complete standby generator quote must show, with verified permit fees, manufacturer gas-line sizing, and the rows installers leave out.

Quick answer: A complete standby generator quote shows 16 line items, not one bundled price. It names the generator model number and its kW rating on your fuel, the transfer switch make, model and amperage, the gas pipe size and the measured run length, the jurisdiction's own permit fee separately from the installer's coordination fee, and the startup and commissioning visit that the manufacturer's warranty requires before coverage begins. The rows most often missing are freight, the panel load calculation, the gas meter capacity check, startup and commissioning, and the first scheduled service at 25 engine hours. A quote missing the gas pipe size, the meter responsibility, or the transfer switch model is not a fixed price, it is an opening number: those three omissions are what turn a $9,400 quote into a roughly $16,000 invoice. Ask for every row in writing, itemized, before you sign anything.

Installed standby-generator costs in New York: NYC's flat permit fee, Long Island's valuation-based fee, state electrician rules, and Sandy-era flood codes.

Quick answer: A whole-house standby generator installed in New York typically runs $12,000 to $18,000 or more all in, tracking at or above the national range this site quotes everywhere once the machine, pad, gas line, automatic transfer switch, permits, and labor are counted, with downstate labor costs in the NYC metro, Long Island, and Westchester pushing many projects toward the higher end. The real twist in New York is not the price, it is the paperwork. New York State issues no statewide electrician license at all: licensing is handled town by town, city by city, and village by village, so a master electrician licensed in one town is not automatically licensed one town over, let alone in New York City. Permit fees follow the same fragmented pattern: New York City charges a flat per-device fee for generator equipment, while a Long Island town like Oyster Bay prices the same permit off the value of the job on a sliding scale, a structurally different system a few miles apart across a county line. And in New York City's flood zones, the building code adopted after Superstorm Sandy requires a generator to sit at or above a specific flood elevation, a real site-planning cost this site has not documented in any other state. Confirm your electrician's specific town license and your flood-zone status before a dealer quote arrives.

Installed standby-generator costs in Georgia: why the online average looks low, Cobb County and Savannah permit fees, statewide licensing, and Helene's lesson.

Quick answer: A whole-house standby generator installed in Georgia typically runs $12,000 to $18,000 or more all in, the same national range this site quotes everywhere, once the machine, pad, gas line, automatic transfer switch, permits, and labor are all counted. Watch for a trap specific to Georgia's own search results: a popular online average for Atlanta, around $7,128, with a typical range of $3,749 to $10,620, prices the generator and its direct labor, not the full permitted project, so it reads well below what a complete install actually costs. Permit fees themselves are modest and consistent rather than a jurisdiction-to-jurisdiction surprise: Cobb County charges a flat $80 residential trade permit, and the City of Savannah charges $80 for its own generator-specific permit, both plus a small technology fee. Licensing is the simplest of any state this site has covered: Georgia law bars cities and counties from adding their own licensing requirements on top of the state electrical contractor license, so one license, the Division of Electrical Contractors' Class I or Class II, covers the whole state. Budget the full project, not the sticker you saw online, before a dealer quote arrives.

Installed standby-generator costs in North Carolina: the Wake County vs. Raleigh permit split, NCBEEC licensing, coastal wind zones and Helene's outage lesson.

Quick answer: A whole-house standby generator installed in North Carolina typically runs $12,000 to $18,000 or more all in, in line with the national range, once the machine, pad, gas line, automatic transfer switch, permits, and labor are all counted. Permit fees themselves are modest but split in an easy-to-miss way inside the Raleigh metro: Wake County charges a flat $75 for a combined residential electrical, mechanical, and plumbing trade permit, while the City of Raleigh itself charges its own electrical permit starting at $128 in FY26, a different fee for a different jurisdiction just a few miles apart. Licensing has its own twist: North Carolina's electrical contractor license is issued once, statewide, by the NC Board of Examiners of Electrical Contractors, but the individual electrician doing the work may still need a separate local journeyman card, since Raleigh and Charlotte/Mecklenburg County each run their own local journeyman licensing board on top of the state contractor license. North Carolina's coastal counties, Carteret, Dare, and Hyde, also carry a statewide-code high-wind design requirement most of the state does not. Budget the whole project, not the machine sticker, before a dealer quote arrives.

Installed standby-generator costs in Louisiana, including New Orleans and Baton Rouge permits, electrician licensing, and demand after Hurricane Ida.

Quick answer: A whole-house standby generator installed in Louisiana typically runs $9,000 to $18,000 all in, with a Louisiana-based installer's own published range landing at $9,000 to $15,000 for a typical home. Louisiana splits electrical licensing two ways: a state contractor license from the Louisiana State Licensing Board for Contractors is required on any electrical project over $10,000, but that license does not let a contractor pull a permit inside New Orleans, Baton Rouge, or Shreveport, each of which runs its own separate city journeyman and master electrician licensing on top of the state one. Permit fees themselves are modest: Baton Rouge charges a flat $500 for a residential generator permit, and New Orleans uses a formula of roughly $40 plus a few dollars per circuit and per amp of service. Louisiana's building code is also unusual: it is set once, statewide, with no county-added overlay the way Florida's hurricane zones work, but it requires a carbon monoxide alarm in every sleeping room and living area whenever a generator or other outdoor fuel-fired appliance is installed. Budget the whole project, not the machine sticker, before a dealer quote arrives.

Florida standby generator installation costs, Miami-Dade and Broward permit fees, electrician licensing, and hurricane-code pad requirements.

Quick answer: A whole-house standby generator installed in Florida typically runs $8,000 to $20,000 all in, with most mid-size homes landing between $10,000 and $16,000. Florida sits at or below the national $12,000-$18,000 range for the machine and labor, but the state's building code adds cost the national number does not: the pad and anchoring have to meet High Velocity Hurricane Zone wind-load rules in South Florida and sit above base flood elevation everywhere, and only about 16 percent of Florida households have piped natural gas, so most installs add a propane tank. Permit fees themselves are usually small, often under $250 in Miami-Dade and roughly 3 percent of the electrical job's value in Broward, but confirm your electrician holds a state-certified license (valid statewide) rather than only a county-registered one (valid in that county only) before you sign.

What a standby generator costs installed in Texas: Houston and Pearland permit fees, the state electrician license rule, and what Winter Storm Uri changed.

Quick answer: A whole-house standby generator installed in Texas typically runs $12,000 to $20,000 all in, at the higher end of the national range because more Texas homes need a propane tank instead of a natural gas tap. The permit itself is usually cheap, often $40 to $90 in a city like Houston, but installers commonly bill $400 to $1,400 to pull it, coordinate the inspection, and handle the paperwork. Texas has no local substitute for the state electrician license: TDLR requires a licensed electrical contractor for the transfer switch work everywhere in the state, no exceptions. Budget the whole project, not the machine sticker, before you take a dealer quote.

The full home generator buying decision in one page. Standby vs portable, sizing, fuel, transfer switch, installed cost, CO safety, and what to ask before you sign.

Quick answer: Pick the lane before the logo. If your outages run days, budget $12,000 to $18,000 for a standby project, not the $3,000 to $6,000 machine sticker. If they run hours, a $700 to $2,500 portable plus a $400 to $850 interlock covers it for a tenth of the money. Size from your real loads including motor starting watts, pick fuel by what your house already has, and never connect without a transfer switch or interlock. The order of decisions matters more than the brand.

How to budget for generator transfer equipment: interlock kits, manual and automatic transfer switches, electrician labor, permits, and safety.

Quick answer: The transfer equipment is not optional if you want to power house circuits safely. A portable generator often pairs with an interlock or manual transfer switch. A standby generator usually uses an automatic transfer switch.

How to compare generator noise claims, including inverter vs open-frame units, standby placement, local rules, distance, exhaust direction, and what buyers forget.

Quick answer: Generator noise is a placement and load problem, not only a decibel number. Distance, direction, walls, load, enclosure, and local rules decide whether the unit is livable during an outage.

How to think about generator fuel use during outages, including propane tank sizing, natural gas limits, gasoline storage, load, runtime, and refill planning.

Quick answer: Generator runtime is a fuel plan, not just a tank size. Load, fuel type, weather, refill access, and outage length decide whether the generator can actually carry your house.

How to size generator backup for a well pump, including starting watts, 240V circuits, pressure tanks, transfer equipment, and why pump specs matter.

Quick answer: A well pump can change generator sizing because motor starting load is often much higher than running load. Get the pump horsepower, voltage, and starting requirements before choosing the generator.

What to do after using a generator in an outage, including cool-down, refueling safety, oil checks, cords, CO alarms, fuel storage, and service notes.

Quick answer: After an outage, let the generator cool, inspect cords and transfer gear, check oil and runtime, handle fuel safely, document issues, and restock before the next storm.

A symptom-to-cause-to-fix checklist for a generator that won't start: stale fuel, closed valve, choke, low-oil sensor, dead battery, and spark plug.

Quick answer: Most no-starts trace to fuel, not the engine. Start with the basics: fresh gas, the fuel valve open, the choke closed on a cold start, and enough oil, because a low-oil sensor blocks starting. Then check the spark plug, the battery on electric start, and the carburetor. Never crank or run a generator indoors.

The appliance wattage table, running vs starting watts, and a plain kW-to-what-it-runs chart, so you size a generator to your real load, not a nameplate.

Quick answer: Every appliance has two numbers: running watts to keep it on, and a higher starting surge that motors pull for a second or two. Size a generator to your running total plus the single largest surge. A fridge, furnace fan, lights, and one pump fit a 5,000 to 7,500 watt portable; central air needs far more.

Running watts keep things on, starting watts get motors going. The wattage math, an appliance table, and the three sizes that actually fit a home.

Quick answer: Most homes fall into three sizes. To keep the essentials running on a portable, the fridge, furnace fan, lights, and one motor load, you want 5,000 to 7,500 running watts. A standby covering the essential circuits runs 10 to 14 kW. A whole-house standby that runs everything runs 18 to 26 kW. The number that trips people up is not the running watts, it is the starting surge a motor pulls for a second or two, which can be 2 to 4 times its running draw.

The lane decision is your outage pattern. Standby runs $12,000 to $18,000 installed and hands-off. Portable plus interlock, $1,500 to $3,500.

Quick answer: It comes down to your outage pattern. If you lose power a few times a year for hours, a portable plus an interlock kit, $1,500 to $3,500 all-in, is the best value in backup power. If you lose it for days at a time, or you have a well pump, medical equipment, or you travel, a standby at $12,000 to $18,000 installed starts itself and runs as long as the fuel lasts. A home battery is the third lane for short, silent, indoor-safe backup.

The standby machine is $3,000 to $6,000. Installed, the project runs $12,000 to $18,000. The real line items, plus the cheaper portable lane.

Quick answer: A whole-house standby generator is a $3,000 to $6,000 machine bolted into a $12,000 to $18,000 project. The install often costs as much as the generator once you add a concrete pad, gas line sizing, a possible meter upgrade, an automatic transfer switch, an electrician, a plumber, and permits. If your outages are a few short blackouts a year, a $700 to $2,500 portable plus a $400 to $850 interlock covers it for a fraction of that. Size the spend to your outage pattern, not the brochure.

Never run a generator indoors, in a garage, on a porch, or near a window. CO is odorless and kills in minutes. The rules that keep you safe.

Quick answer: Never run a portable generator indoors. Not in the house, not in the garage with the door open, not in the basement, not on a porch, and not next to a window. The exhaust is carbon monoxide, a gas you cannot see or smell that can kill in minutes, and opening a door does not make it safe. Run it outside only, at least 20 feet from the house, with the exhaust pointed away, and keep battery-operated CO alarms on every level.

Natural gas means unlimited runtime and no tank, but a small output derate. Propane works when the gas grid fails, if the tank is sized right.

Quick answer: Natural gas gives a standby generator effectively unlimited runtime with no tank to fill, but air-cooled units lose about 4.5 to 11 percent of their rated output on natural gas versus propane depending on the model, and they stop if the gas grid goes down. Propane works when the gas infrastructure fails and stores for years, but a 22kW standby at half load burns about 2 to 2.5 gallons an hour, so tank size decides how many days you get. On current EIA prices natural gas is the cheaper fuel per hour, roughly $4.26 against $6.55 at half load. If you have a gas line and your outages are grid-only, natural gas is the low-hassle default. If you want fuel you control, propane earns its tank.

Inverter means clean, quiet power for electronics. Open-frame means more watts per dollar and more noise. Which one actually fits your loads.

Quick answer: An inverter generator makes clean power (3 percent THD or less, safe for laptops and TVs), runs quieter, and weighs less, but costs more per watt. Champion publishes about 12 to 20 percent THD for its standard open-frame portables against under 3 percent for its inverters, and the noise gap is real: Westinghouse rates its iGen5000c inverter at 52 dBA while Champion rates its 7500-watt open-frame at 74 dB(A) at 23 feet. Higher THD is fine for motors and heaters and is the wrong choice for a UPS, a pellet stove or a high-efficiency furnace board. Buy the inverter for electronics and quiet, open-frame for storm duty and watts per dollar.

Interlock kit ($400 to $850) vs manual transfer switch (up to $1,500). What each does, code and permits, and why it is all electrician work.

Quick answer: To power your house from a portable generator legally, you need an interlock kit or a transfer switch, wired in by a licensed electrician. An interlock kit runs about $400 to $850 installed and lets you feed the whole panel while you manage the load by hand. A manual transfer switch runs up to about $1,500 and powers a fixed set of circuits with less juggling. Both prevent backfeeding, which is illegal and can kill utility workers. The automatic transfer switch that swaps power for you belongs to the standby lane and runs $2,000 to $5,000 in electrical work.

Buy and test your generator in spring, not the week a storm is named. Test runs, fuel storage, cords, and a carbon monoxide plan done early.

Quick answer: Buy and test your generator in spring, because in the week a storm is named the portables, cords, and fuel cans sell out and prices spike. The spring list is short: a monthly 20-minute test run under load, fuel stored with stabilizer (or propane, which keeps indefinitely), cords and the interlock checked, and a carbon monoxide plan with detectors and a 20-foot placement spot chosen in advance. When a storm is named you just fuel up, run a test, charge everything, and review the CO plan.

Short outages favor a battery, silent and indoor. Multi-day outages favor a generator you can refuel. Real installed costs and when the answer is both.

Quick answer: The split is clean. For short outages measured in hours, a home battery wins: silent, indoor-safe, no fuel, and it switches over instantly. For outages measured in days, a generator wins, because you can refuel it and a battery runs down. A standby generator is $12,000 to $18,000 installed, a home battery is $10,000 to $30,000 installed, and a portable plus interlock is $1,500 to $3,500. For a lot of homes the real answer is both.

Portable generator safety per CPSC: carbon monoxide, the 20-foot rule, safe refueling, wet weather, overload, and backfeeding, served straight.

Quick answer: Run a portable generator outside only, at least 20 feet from the house, with the exhaust pointed away from doors, windows, and vents. Never run it inside a home, garage, basement, crawlspace, shed, or on a porch, even with the doors open, because the exhaust is carbon monoxide and it kills more than 80 people a year (CPSC). Put battery-operated CO alarms on every level of the house, refuel only when the engine is off and cool, and have a licensed electrician wire in an interlock or transfer switch so you never backfeed the grid.

Standby service runs $200 to $400 a year plus oil and a battery every 2 to 3 years. Portable owners pay in stale fuel and no-starts.

Quick answer: A standby generator costs $200 to $400 a year for a service contract, plus an oil and filter change and a new starting battery every two to three years. A portable costs less in dollars and more in discipline: gasoline goes stale in one to three months without stabilizer, and gummed carburetors are the number one reason a generator will not start when the storm hits. Propane does not go stale, which is the quiet advantage of a dual-fuel portable. Budget the upkeep before you buy, because the year-three no-start is a pattern, not bad luck.

The generator regrets owners repeat most, from the quote that doubled to wishful watts and self-test noise, each with the number and the fix.

Quick answer: Most generator regrets are not about the brand. They are about the quote that doubled from a $6,000 machine to a $16,000 install, watts that looked bigger on the box than in the driveway, and no legal way to connect a portable without a $400 to $850 interlock. Add stale fuel that kills a portable by year three, oversized standby units burning fuel on a weekly test, and maintenance contracts that turn out to be mandatory for the warranty. Every one of them is avoidable if you price and size the whole project before you buy.

Generac vs Kohler compared for real buyers. Dealer network, warranty, self-test noise, and why the installed cost is the same for both.

Quick answer: Both Generac and Kohler build credible whole-house standby generators, and the installed cost is the same $12,000 to $18,000 for either. Generac's advantage is reach: it claims the largest factory-direct dealer network in North America. Kohler's advantage is the warranty structure, because its 5 years cover parts, labor and travel throughout while Generac drops to parts after year 2. On noise the folklore is out of date: Generac publishes 55 dB(A) in Quiet-Test against 56 for a Kohler 26RCA and 66 for a Kohler 20RCA. Pick Generac for network reach, Kohler for coverage and a strong local dealer.

Quiet Honda inverters, Westinghouse value, Champion and DuroMax dual-fuel for storm duty, and the interlock every portable pick actually needs.

Quick answer: For quiet backup that is safe for electronics, a Honda EU2200i (1,800 running watts, around $1,200 est.) or a Westinghouse iGen5000c inverter ($1,199 list, built-in CO sensor) is the pick, and the smaller iGen4000c ($799) covers a fridge-and-phones outage on a tighter budget. For storm duty, a well pump, or half the house at once, a Champion or DuroMax dual-fuel open-frame gives you 7,500 to 10,500 running watts for roughly $800 to $1,100 est. Whatever you buy, a portable that powers your panel needs a $400 to $850 interlock installed, and a model with a carbon monoxide shutoff sensor is the safety tiebreaker.

Compare the best home standby generators, Generac, Kohler, Briggs, Cummins and Champion, with the real installed cost of $12,000 to $18,000.

Quick answer: The best all-around home standby generator is a Generac Guardian, because nothing else matches its dealer and parts network. But the machine is the smaller half. Air-cooled whole-house units run $3,000 to $6,000 for the box and $12,000 to $18,000 installed, and that installed number barely changes between brands. Kohler, Briggs & Stratton, Cummins, and Champion are all credible, so the real tie-breakers are warranty length and which brand your local dealer actually services.
