Whole-House Generator Installation and Service in the Grand Strand

When a tropical system, ice storm, or transformer failure takes the grid down along the Grand Strand, a properly sized standby generator is the difference between a few seconds of inconvenience and days without power. Greg Beverly Services, Inc. has been installing and servicing whole-house generators for South Carolina coastal homeowners and businesses since 1985. We size each system to the home, manage the full permitting and inspection process, coordinate with the utility on the gas connection, and stand behind every installation with a one-year labor warranty on top of the manufacturer’s coverage.

Our installers are licensed South Carolina electricians, not subcontracted labor, and our office in Murrells Inlet means we are minutes away from Pawleys Island, Litchfield Beach, Surfside Beach, Garden City, Carolina Forest, and Myrtle Beach. Whether you are protecting a primary residence, a coastal vacation home, or a commercial property that cannot afford downtime, we deliver a generator solution that is sized correctly, installed cleanly, and supported for the life of the equipment.

Horry and Georgetown counties sit in one of the most lightning-active and hurricane-exposed regions in the Southeast. Extended outages are not a remote possibility — they are a documented annual reality. The combination of Atlantic tropical activity from June through November, frequent severe thunderstorms, and occasional winter ice events means most Grand Strand neighborhoods lose power at least once a year and many lose it several times.

A whole-house standby generator eliminates that disruption. Within seconds of detecting a grid outage, an automatic transfer switch isolates your home from the utility and starts the generator. Your HVAC stays on, your refrigeration and freezers stay cold, your sump pumps and well systems stay running, and your medical equipment, internet, and security systems stay live. For homes with short-term rental income, a generator is also business-critical infrastructure — a single weekend cancellation during peak season can cost more than the annual maintenance on a generator.

Beyond storm protection, a standby generator adds measurable value at resale. Coastal South Carolina buyers increasingly view a permanent generator as a baseline expectation in the $500K-plus market, particularly for homes purchased as second properties.

Every generator project follows the same six-step process so there are no surprises and no scope drift.

1. On-site load assessment. We visit your property to measure square footage, document existing HVAC and pump loads, check panel capacity, identify the best pad location relative to the gas meter and panel, and confirm setback distances from windows and openings under current code.

2. Written estimate. You receive a line-item estimate showing the generator model and kW rating, transfer switch, pad, electrical and gas runs, permit fees, and any required panel work. No vague allowances and no hidden change orders.

3. Equipment order. Once approved, we order the generator and transfer switch. Typical equipment lead time is 4–6 weeks; supply chain has improved significantly since 2024.

4. Permits and utility coordination. We pull the electrical and mechanical permits with Horry or Georgetown County and coordinate the gas service or upgrade with Santee Cooper or your propane provider.

5. Installation. On-site installation typically takes 2–3 days. We pour or place the pad, run the gas line, install the transfer switch, wire the generator into the panel, and clean up the site as we go. Your home is on grid power throughout the install with only a brief planned outage for the transfer switch cutover.

6. Commissioning and walkthrough. We run a full operational test under load, verify automatic transfer in both directions, register the warranty in your name, and walk you through monthly self-tests, the mobile monitoring app, and the maintenance schedule. You receive the permit close-out, warranty registration, and maintenance booklet.

We are authorized installers for both Generac and Kohler residential standby generators. Both manufacturers produce reliable, code-compliant systems with strong dealer support in coastal South Carolina, and the right choice for your home depends on load profile, fuel source, and budget.

The most widely installed residential standby brand in the country. Strong parts availability, the Mobile Link remote monitoring app is reliable, and the price point on the 18kW–22kW models is typically the best value for a 2,000–3,000 sq ft home. We install the full Guardian Series along with the larger Protector Series for homes above 4,000 sq ft.

A premium option with somewhat quieter operation under load and a 5-year limited warranty as standard. Kohler is often the right call for larger homes, homes in close-built neighborhoods where sound profile matters, or homeowners with a strong brand preference. The OnCue Plus monitoring platform is robust.

We size every system using actual measured loads, not generic square-footage estimates. A 22kW generator is right for many Grand Strand homes, but a 26kW or 32kW may be needed where there are dual HVAC systems, electric water heaters, pool pumps, or a planned EV charger. Undersizing a generator is the most common mistake we see when we are called in to service or replace systems installed by other contractors.

A standby generator only protects your home if it starts when the grid goes down. The leading cause of generator failure during an actual outage is skipped maintenance — typically a battery that has aged out, a fuel system issue, or a control board fault that an annual service would have caught.

We perform annual maintenance on Generac, Kohler, and most other major residential and commercial standby brands. A standard annual service includes:

• Oil and filter change
• Air filter inspection and replacement as needed
• Spark plug inspection
• Battery load test and replacement when below threshold
• Coolant check and top-off (for liquid-cooled units)
• Transfer switch operational verification
• Control panel firmware update
• Full load test with documented runtime and voltage readings

We recommend scheduling annual service between April and early June so the system is verified before hurricane season opens June 1. We also offer 24-hour emergency service for active outages — if your generator fails to start when you need it, we will respond as quickly as conditions allow.

We install and service standby generators throughout Horry and Georgetown counties, including:

• Murrells Inlet (our home base)
• Pawleys Island
• Litchfield Beach
• Georgetown
• Surfside Beach
• Garden City
• Myrtle Beach
• North Myrtle Beach
• Carolina Forest
• Socastee

40+ years on the Grand Strand. We have installed generators through every major storm cycle since 1985, including Hugo, Floyd, Matthew, Florence, Dorian, and Idalia. We understand what coastal generators face here.

Licensed South Carolina electricians. Every install is performed by licensed electricians under full liability coverage. We never use unlicensed labor.

Permits pulled, inspections passed. We do not deliver a project until it has cleared inspection with Horry or Georgetown County. You receive the close-out documentation.

Authorized Generac and Kohler installer. Manufacturer-backed warranties registered in your name on the day of commissioning.

One-year labor warranty. On top of the manufacturer warranty. If anything is not right, we come back.

Local office in Murrells Inlet. Not a regional dispatch center routing your call through three states. You talk to the same team that installed your system.

Hurricane season opens June 1. The homes that are protected when the grid goes down are the ones whose owners decided in March. If you have been thinking about a standby generator, the right time to start the conversation is now — equipment lead times push installs out 4–8 weeks once the contract is signed.
