Charlotte homeowners feel the outages more each year. Summer thunderstorms knock trees onto lines. Ice storms glaze the power grid. Humidity loads the HVAC and strains Duke Energy during peak demand. For many homes in Mecklenburg County, a whole house generator moves from a nice-to-have to a practical safeguard.
Ewing Electric Co. installs standby generators across Charlotte and nearby towns like Matthews, Pineville, Huntersville, Mint Hill, Concord, Belmont, and Gastonia. The team focuses on seamless backup power for HVAC, medical devices, home offices, and sump pumps. This article explains when a generator is worth it, what the installation involves, and how to size and select the right system for a Charlotte home.
Signs a Standby Generator Is the Right Call
Frequent power interruptions are the first sign. Homeowners in 28277 and 28210 report brownouts and short outages during heavy heat. Those in older neighborhoods such as Myers Park and Dilworth face mature tree canopies that drop limbs during storms. Ballantyne and Steele Creek see fast growth, which adds electrical load.
A second sign is risk. If a home relies on a sump pump, a refrigerator full of groceries, refrigerated medications, a CPAP machine, or a home office that must stay online, the cost of an outage adds up fast. A standby system for Charlotte’s climate keeps the air conditioning running during sticky summers and protects pipes and electronics during winter ice events.
A third sign is lifestyle. Some families travel. Some own rental property in NoDa or Plaza Midwood where tenants expect stability. Others care for elderly parents. In these cases, automatic backup power is a smart investment.
What a Whole House Generator Does During Grid Failure
A standby generator sits outside on a concrete pad in a weatherproof enclosure. It connects to a natural gas line or a propane tank. The system ties into the home’s electrical panel through an Automatic Transfer Switch. During a power outage, the unit senses the loss, starts, and flips the transfer switch within seconds. Lights come back. The HVAC restarts. Refrigerators, medical devices, and routers keep running.
Ewing Electric’s team handles the full integration of the Automatic Transfer Switch with the existing breaker panel. For larger homes in South Park or estates near Freedom Park, the crew can install a subpanel for essential loads or deploy smart load management to stage heavy circuits like air conditioning and electric ranges.
Generator Types That Fit Charlotte Homes
Air-cooled standby generators suit most single-family homes in neighborhoods like Dilworth, Elizabeth, and Plaza Midwood. Typical sizes range from 14 kW to 26 kW depending on load. They offer solid performance and value.
Liquid-cooled generators fit larger homes and luxury estates where long runtime and heavy loads matter. This option is common in South Park and Myers Park properties with multiple HVAC condensers, pool equipment, and EV charging.
Dual-fuel models are available where natural gas is not present. A propane tank provides long runtime when storms disrupt service roads.
Ewing Electric specializes in air-cooled units for standard homes and liquid-cooled systems for higher demand sites. The technicians size the unit by running a professional load-calculation that accounts for HVAC tonnage, heat strips, well or sump pumps, refrigerators, freezers, ovens, and office equipment.
Brands, Warranty, and Noise
Brand choice affects reliability, service access, and parts availability. Ewing Electric installs Generac and Kohler units across Mecklenburg County and keeps common parts on hand. Champion, Briggs & Stratton, Cummins, Honeywell, and Westinghouse also serve distinct needs and budgets. Many homeowners pick Generac Guardian for a balance of price and support. Kohler appeals to those who value quiet operation and durable enclosures. Homeowners who want advanced remote monitoring and low sound often upgrade to a Honeywell standby system.
Factory-trained technicians protect the warranty. Ewing Electric is a licensed, insured, and bonded electrical contractor. The company offers maintenance contracts, remote monitoring options, and annual service to keep systems ready.

Real Charlotte Scenarios
A family in 28277 with two heat pumps and a sump pump had repeated summer outages. A 22 kW air-cooled unit solved basement flooding risk and kept their home office online.
A homeowner near Bank of America Stadium works night shifts at the airport. Power interruptions made CPAP therapy unreliable. A compact standby unit with an ATS now restores power in seconds.
A Myers Park estate near Queens University of Charlotte required a liquid-cooled generator with smart load management. Noise limits and tight setbacks called for proper siting and a tuned enclosure.
The Installation Process, Step by Step
- Site survey and load-calculation: The electrician measures real demand, reviews the electrical panel, and confirms gas capacity. Permitting and inspections: Ewing Electric manages city permits, HOA paperwork where needed, and schedules inspections with Mecklenburg County. Concrete pad and placement: The crew pours a level pad and sets the enclosure with clearance to meet code and neighborhood noise ordinances. Gas and electrical integration: Coordination with licensed gas plumbers for natural gas line or propane tank sizing. Wiring the ATS and any subpanel or smart load management devices. Startup, meter sync, and training: Final Duke Energy meter coordination, full system test under load, and homeowner walkthrough on weekly exercise and alerts.
What It Protects During Charlotte Weather
Thunderstorms in late spring and summer bring voltage spikes and outages. An ATS and voltage regulator protect sensitive electronics. Ice storms can cause multi-day outages. The battery charger and auto-start logic keep the system ready to run. Rolling blackouts during extreme heat can last hours. A standby unit maintains HVAC and prevents food spoilage. Storm damage can knock out well pumps and sump pumps. Backup power prevents basement flooding and water supply loss.
Sizing and Fuel Considerations
Right sizing matters. Too small, and the generator struggles to start HVAC compressors. Too large, and the cost is unnecessary. The technician calculates total load in kilowatts and considers starting surges. One 4-ton air conditioner may require 7 to 10 kW to start, then 3 to 4 kW to run. Add refrigerators, lighting, and outlets, and the typical Charlotte home lands between 18 kW and 24 kW for whole-home coverage.
Natural gas is common within Charlotte city limits and offers continuous fuel supply. For homes in parts of Huntersville or Mint Hill without gas service, propane is reliable, with tanks sized to support multi-day runtime. Dual-fuel options provide flexibility.
Local Codes, Noise, and Placement
Historic districts like Myers Park Homepage and Dilworth have specific rules on equipment placement. South Park estates and lots near Freedom Park may have tighter noise sensitivity. Ewing Electric works within these constraints. Placement choices include side yards with privacy fencing, rear patios with proper exhaust clearance, and setbacks that meet manufacturer specs and Mecklenburg County code.
Maintenance That Keeps the System Ready
Standby units should exercise weekly to keep fluids moving and batteries charged. Annual service includes oil and filter changes, spark plugs, valve checks on some models, battery inspection, and firmware updates for remote monitoring. Ewing Electric offers maintenance contracts with reminder scheduling, which keeps warranties valid and performance steady.
Cost Ranges and What Affects Pricing
Most air-cooled whole-home systems in Charlotte fall in a range that reflects generator size, gas line length, pad work, ATS type, and permitting. Liquid-cooled units cost more but are the right fit for high-demand homes. The best way to get accurate pricing is a site visit with whole home generator installation a load-calculation. Ewing Electric provides a free generator installation estimate after the assessment.
Neighborhood Coverage and Response Time
Ewing Electric serves the Queen City from Ballantyne to Huntersville, Steele Creek to NoDa, and everything between. Located within range of Freedom Park and Charlotte Douglas International Airport, the team provides fast response and clear scheduling windows. The company is familiar with inspections in zip codes 28202, 28205, 28210, 28226, 28269, and 28277. Work near landmarks such as Discovery Place Science and the U.S. National Whitewater Center helps the crew plan logistics and minimize disruption.
The Anatomy of a Professional Installation
A clean installation begins with a level concrete pad, an enclosure placed to code, and a fuel source sized for peak demand. The Automatic Transfer Switch routes power safely and isolates the home from the grid during outages. A subpanel can separate essential loads if full coverage is not needed. Smart load management sheds noncritical circuits so the generator never overloads. The final step is the Duke Energy meter sync and a controlled test that proves the system through several start-stop cycles.
