Generac Generator Installation: Pricing Breakdown and Who’s Qualified to Install It
A home standby generator is one of those upgrades you appreciate most on the worst day. In Charlotte, summer storms and winter ice can knock out power without warning. If you work from home, have a medical device, or want to protect a finished basement from sump pump failure, a Generac standby generator is a smart move. Homeowners search for Generac generator installation near me because they want accurate pricing, a clean install, and a company that answers the phone after the first storm line passes. This guide lays out what drives cost, how permitting and gas work plays into it, and who can legally and safely install your system in Charlotte, NC.
Ewing Electric Co. installs Generac standby generators across Charlotte and surrounding areas, from Dilworth and Plaza Midwood to Ballantyne, SouthPark, Steele Creek, Huntersville, and Matthews. We work side by side with local inspectors and utility providers every week. The details below reflect real jobsite experience in this market, not guesses from a national average.
What you’re paying for: the real cost components
A full standby generator installation is more than the metal box on a pad. Pricing breaks into predictable pieces. You can control some of these with early decisions, but others depend on your property and local codes.
Generator unit. The generator itself is the largest single cost. A residential Generac air-cooled unit ranges from 10 kW to 26 kW. Expect about $3,000 to $6,500 for smaller units and $6,500 to $10,500 for larger air-cooled models, including standard warranty. Liquid-cooled units start higher and serve large homes with heavy loads or multiple HVAC systems. Most Charlotte homes land in the 18 to 24 kW air-cooled range.
Automatic transfer switch. The ATS senses power loss and shifts your home to generator power. Generac offers service-entrance rated switches that combine your main disconnect and ATS, which can save space and streamline the installation. Typical ATS cost runs $700 to $2,500 depending on amperage and features.
Electrical labor and materials. This covers panel work, conductors, conduit, breakers, grounding, and the generator pad and set. In Charlotte, trenching may be needed if the generator sits away from the meter and panel. For a straightforward set within 10 to 15 feet of the service, electrical labor and materials often run $2,000 to $4,000. Longer runs, meter upgrades, or panel rearrangements increase this line.
Gas work. Your generator needs natural gas or propane. Natural gas is common in Charlotte neighborhoods. The gas line must be sized for generator demand and other appliances. If your meter is undersized, Piedmont Natural Gas may need to upgrade it, sometimes at no charge, sometimes with a fee, depending on current usage and the increase. Expect $800 to $2,500 for typical gas piping on a short run. Longer runs, upsizing interior piping, or tank sets for propane add cost.
Concrete or composite pad. Many Generac units ship with a composite pad. Some sites require a poured pad for stability or to meet floodplain needs. Concrete pads in our area run $300 to $700 for a standard residential footprint.
Permits and inspections. Mecklenburg County Code Enforcement requires electrical and mechanical (gas) permits. Budget $200 to $600 total for permits. Homeowners associations may require an architectural review with screening or placement guidelines.
Site prep and restoration. Clearing shrubs, relocating AC linesets, or cutting and patching concrete can add $200 to $1,000. If the generator sits along a side yard in Myers Park or Dilworth where lot lines are tight, we plan setbacks carefully and sometimes add sound fencing, which carries a separate cost.
Startup, testing, and training. A proper install includes factory startup, voltage checks under load, and homeowner orientation. Reputable installers roll this into the project price. If you see it as an add-on, ask why.
A typical all-in price for a complete Generac air-cooled install in Charlotte, including equipment, ATS, gas, electrical, permits, pad, and startup, usually falls between $8,500 and $15,000. Homes with long gas or electrical runs, multiple panels, or meter upgrades can push higher. If a quote is far below that range, it may be missing necessary scope. If it is far above, ask for a line-by-line breakdown to compare assumptions.
Sizing a Generac generator the right way
Oversizing costs more upfront and may not run efficiently at low loads. Undersizing leaves you short when both heat and the oven call for power. We size based on actual loads, not guesswork.
Start with the service size and your must-run list. Most homes Take a look at the site here in Charlotte have 150 or 200 amp services. We ask what you must power during an outage. Common essentials are the refrigerator, microwave, lighting in key rooms, outlets for phone and internet, a sump pump, a well pump for rural properties, and one or two HVAC systems. If you have a tankless water heater, hot tub, EV charger, or heavy shop tools, we plan around them.
Understand HVAC start-up loads. Air conditioners and heat pumps have inrush currents that spike on startup. Generac’s larger air-cooled units with smart load management handle this well, but we verify tonnage, minimum circuit ampacity, and lock rotor amps on the nameplate. On a recent Ballantyne install, a 3-ton heat pump and a gas furnace blower paired well with a 18 kW unit using two load-shed modules. For a SouthPark home with dual 4-ton condensers, we stepped up to a 24 kW and staged HVAC starts through the ATS.
Plan for electric ranges and dryers. These are heavy continuous loads. Some homeowners choose to run one at a time during outages. We can program load shedding so non-essentials pause when the HVAC kicks on, then resume. This approach keeps generator size reasonable without giving up comfort.
Consider future loads. If you plan to add an EV charger in the next year, say so. We can rough-in capacity or conduit now. It is cheaper to plan ahead than to revisit a finished installation.
Most 2,000 to 3,500 square foot homes in Charlotte end up with an 18 to 24 kW air-cooled Generac that supports one or two HVAC systems and common circuits. Larger homes, all-electric houses, or properties with significant well or pool equipment may require a 26 kW air-cooled or a liquid-cooled model.
Who is qualified to install a Generac generator in Charlotte
Two trades are essential: a licensed electrical contractor and a licensed mechanical contractor for gas. Sometimes one company holds both licenses or partners closely with a gas fitter. The key is that the names on the permits match the work performed.
Electrical licensing. In North Carolina, residential and intermediate electrical contractors carry license numbers you can verify with the NC Board of Examiners of Electrical Contractors. Look for an established company with permitting history in Mecklenburg County. Experience with service-entrance rated ATS gear, grounding and bonding, and load calculations matters. The installer should pull an electrical permit under their license and schedule inspections.
Gas licensing. Gas piping falls under mechanical licensing. For natural gas tie-ins, the contractor coordinates with Piedmont Natural Gas. For propane, a licensed propane supplier sets and connects the tank. The mechanical permit, pressure test, and inspection are mandatory.
Generator certification. Generac trains and certifies installers. Factory-trained techs perform warranty startup and have access to parts and software updates. Ask whether your installer is a Generac PowerPro or holds current factory training. It affects response time and warranty support.
Insurance and compliance. Confirm general liability and workers’ compensation insurance. Ask to see recent inspection approvals for similar projects in Charlotte or your neighborhood. A company that installs weekly will know subtle code updates, such as NEC grounding updates or clearance requirements, that a general handyman will miss.
Ewing Electric Co. holds the proper electrical licensing for standby systems in Charlotte and works closely with trusted gas partners. We pull permits, coordinate inspections, and perform factory startups, so your warranty and code compliance are covered.
The installation process you should expect
A clean install follows a predictable arc. Timelines vary by utility scheduling and HOA approval, but the steps hold steady.
Site visit and load review. We walk the property, review your panel, check gas meter capacity, and map the generator location. We flag setbacks from windows, doors, and vents. Side yards in older neighborhoods often dictate tighter placements, which we handle with code-compliant clearances and sound considerations.
Proposal with detailed scope. A good proposal lists the generator model, ATS, pad type, trenching, gas work, permits, startup, and any panel upgrades. It should also state lead time and what is required from you, such as HOA documents or landscape changes.
Permitting and scheduling. We submit electrical and mechanical permits to Mecklenburg County. If Piedmont Natural Gas needs to upsize your meter, we request it early to avoid delays. HOA submissions can take a week or two depending on the board.
Install day. We set the pad, place the generator, run conduit and conductors to the ATS, and complete panel tie-ins. We run gas piping, pressure test, and leave gauges on for inspection. The yard stays neat, and pathways remain clear. Most single-family installs complete in one to two days of on-site work.
Inspections and startup. County inspectors check electrical and gas work. After approvals and gas turn-on, we perform factory startup, set exercise schedules, test under load, and walk you through operation and maintenance.
We also register your generator for warranty and set you up with maintenance options. Homeowners who travel or own rental property often prefer an annual service agreement so they are not chasing oil changes every two years.
Permits, clearances, and code items that matter in Charlotte
Local code is there to keep you safe and prevent nuisance issues with neighbors.
Setbacks and clearances. Generac requires specific distances from openings and combustible materials. Common practice is at least 5 feet from windows and doors and adequate space around the unit for service. Some HOAs ask for fencing or shrubs for screening. We plan airflow so screening does not choke the intake or exhaust.
Noise. Generac air-cooled units run in the low-to-mid 60s dB at 23 feet under load, which is comparable to a central AC unit. Placement matters. We avoid direct line-of-sight to bedroom windows on neighboring properties where possible.
Grounding and bonding. The ATS type dictates grounding strategy. Service-entrance rated ATS units require careful bonding and neutral handling. We follow NEC and local interpretations that our inspectors expect.
Gas meter sizing. A common snag is marginal meter capacity. If your meter supports a furnace, water heater, range, and grill, adding a 18 to 24 kW generator can exceed capacity during a cold snap. We do the math and file the meter upgrade request early.
Floodplain and grading. In low-lying parts of Charlotte, flood maps may require elevating the generator pad. We handle risers or pier pads to meet the base flood elevation if needed.
Ongoing costs you should plan for
A generator is an appliance, and like any machine that starts under load, it needs maintenance.
Fuel during exercise and outages. Generac units run a weekly exercise, usually 12 minutes. Fuel use during exercise is minimal. Under load, fuel consumption depends on size and demand. A 22 kW air-cooled unit might use roughly 2 to 3 cubic feet of natural gas per minute at half load. For propane, plan around 2 to 3 gallons per hour at half-to-full load ranges. If you use propane, sizing the tank at 250 to 500 gallons prevents frequent deliveries during storms.
Oil and filters. Air-cooled models need oil and filter service every two years or 200 hours, whichever comes first, and a valve adjustment at specified intervals. Most homeowners spend $200 to $400 per routine service visit when handled by a professional.
Battery replacement. Generator starting batteries last 3 to 5 years in our climate. Budget $100 to $200 when it is time.
Repairs and warranty. Generac warranties vary by model, commonly 5 years limited for residential units. Using a factory-trained startup and following service intervals protect coverage. Keep records.
Remote monitoring. Many Generac models support Wi-Fi monitoring. It is helpful to get alerts if a weekly exercise fails or a battery voltage drops. Connectivity depends on your home network; we recommend a stable 2.4 GHz signal near the unit or a dedicated extender.
Ways to save without cutting corners
Homeowners often ask how to control cost while keeping reliability high. There are smart moves that do not compromise safety or code.
Right-size the generator. Do not oversize for rare loads. If you only bake a turkey once a year, you can live without the oven during an outage. This decision alone can shift you from a 24 kW to an 18 kW unit and save thousands.
Use load management. Generac load-shed modules let you run a smaller generator while still handling big appliances. When the AC starts, the water heater pauses for a minute. You never notice it, and the generator stays within capacity.
Plan placement for shorter runs. Putting the generator near the electrical service and gas meter reduces trenching and conduit length. We still follow clearances and HOA rules, but a shorter run means less material and labor.
Combine projects. If you already plan a panel upgrade or EV charger, we can coordinate work. Shared trenching and panel time reduce total cost relative to separate jobs.
Schedule ahead of storm season. Lead times spike after region-wide outages. If you plan in spring or early fall, utility and inspection schedules are often smoother.
Common pitfalls and how we avoid them
We see patterns in problem installs that lead to callbacks or failures.
Undersized gas piping. The generator starts, runs for a minute, then stumbles. That is often a fuel supply issue. We size the pipe and regulator for full load and verify pressure during startup.
Improper neutral bonding. Mixing service-entrance rated ATS gear with subpanel neutrals can create stray currents or tripping. Our electricians follow a clear bonding plan and label panels for future service.
Poor placement. Tucking a generator into a narrow alcove seems neat until it overheats or bothers a neighbor’s bedroom window. We place for airflow, service access, and sound.
Skipping permits. It is faster until it is not. Insurance claims, home sales, and utility work all get sticky without a permitted install. We pull the proper permits every time.
No startup verification. Turning the key and hearing it run is not enough. We test under load, verify voltage and frequency, and confirm the ATS cycles cleanly. This is where small wiring mistakes show up before they can cause harm.
Why homeowners search “Generac generator installation near me” in Charlotte
Local matters for this type of project. Site conditions, HOA expectations, and utility coordination are all local. An installer who works daily in Charlotte, Pineville, Mint Hill, and Davidson knows which alleys are tight, which neighborhoods push for side-yard screening, and which inspectors prefer certain labeling. Local also means a faster response during the first hot week in June when two pop-up storms expose weak batteries across town.
Searchers use Generac generator installation near me because they want a company that answers a local number, shows up to walk the site, and is still available after the invoice. That is our business model at Ewing Electric Co.
A quick look at example projects and costs
SouthPark two-story with dual HVAC, gas heat, and gas water heater. We installed a 22 kW Generac with a 200A service-entrance rated ATS. Gas meter upgrade by utility, 20-foot gas run, 15-foot electrical run, composite pad. Permits and inspections smooth, HOA asked for a low hedge. All-in around $12,800.
Matthews ranch on propane with well pump. 18 kW Generac with 100A ATS feeding essential circuits, new 500-gallon underground propane tank by supplier partner, trenching across yard. Slightly longer schedule due to tank install and landscaping. All-in around $14,900 with tank work included.
NoDa bungalow with small footprint and tight side yard. 14 kW Generac with smart load management for AC and water heater. Short runs but creative placement for setbacks from windows. All-in around $9,600.
These are examples, not quotes. They show how placement, fuel, and load choices shape the budget.
How to prepare your home and your expectations
Before we arrive, clear a path to the electrical service panel and gas meter. If you plan to change landscaping or fencing, tell us. We confirm access for trenching and equipment. If pets are on site, we plan so gates stay closed. During install, power may be off for a short window while we tie in the ATS. We schedule that window when it suits you. After startup, we set weekly exercise for a time that will not disturb your household or neighbors.
For homes with security systems and smart devices, remember that a generator powers your circuits, but your internet and cable provider’s neighborhood equipment also needs power to keep service flowing. In many outages, the network stays up, but in wide outages, it may not. We can back up your modem and router circuits regardless.
Maintenance and service support from a local team
After installation, a simple maintenance plan keeps your generator ready. We offer annual service that includes oil and filter changes at the right interval, battery testing, firmware checks, and a full system run under load. If the generator sends an alert, you call a local number. During widespread outages, our service queue prioritizes clients with medical or sump pump needs, and we communicate realistic arrival windows.
We also offer an assessment for older generators. If you moved into a Charlotte home with an existing Generac, we can evaluate it, run it under load, and give an honest view on whether to keep it or replace it. Many 10 to 15-year-old units run well with basic refresh work.
Straight answers to frequent questions
How long does a Generac install take? The actual on-site work takes one to two days. Permits and inspections add time. If a gas meter upgrade is required, the overall timeline often lands at two to four weeks start to finish. HOA reviews can extend that.
How loud is the generator? Similar to an AC condenser. Placement and terrain make the biggest difference. We can add sound screens if an HOA or neighbor asks for it, while keeping airflow clear.
Will it power my whole house? It can, but many homeowners choose essential circuits with load management. Whole-home coverage usually means a 22 to 26 kW unit for gas-heated homes and a larger or liquid-cooled unit for all-electric homes. We’ll show you both options with costs.
Is financing available? Many clients prefer financing to keep cash free for other projects. We can discuss current options during your site visit.
What happens during annual service if I’m out of town? With your permission, we can perform maintenance without you present, and we’ll send photos and a report.
