Keep the Power
—and Peace of Mind—
On
Generator repair Charleston SC & preventive maintenance by Lowcountry’s factory‑authorized experts.
When hurricanes rattle the coast, a silent standby generator isn’t an option.
MHG Maintenance keeps Charleston‑area homes bright and safe with on‑site service that meets every line of your Generac warranty. We also protect your hot‑water comfort with professional instant water heater cleaning—all in one visit.
Why Generators Fail (and How We Stop It)
Industry studies tie most “won’t‑start” calls to batteries and starters stressed by salt air and heat. Our annual checklist changes oil, filters, and sparkplugs; load‑tests the battery; updates firmware; and seals units against rodents—locking in Generac warranty coverage for up to five years.
Our Services at a Glance
Maintenance Plans
Annual or semi‑annual flat rates record every service for proof and resale value.
Standby Generator Repair
Starters, controller displays, and alternator swaps completed on your pad—no shop haul‑away.
Instant Water Heater Cleaning
A 40‑minute tankless flush every 12–24 months clears mineral scale, restores pressure, and can cut energy bills.
24/7 Remote Monitoring
Mobile Link FLEET pings you—and us—about low battery, faults, or skipped exercise tests for just $145 per year.
Maintenance Pays for Itself
Routine service can slash emergency repair costs by a third and extends engine life well beyond the five‑year warranty window. Municipalities budget six‑figure contracts for the same reason: prevention beats downtime.
Built for the Lowcountry Climate
South Carolina logged more than three million utility customers—with hundreds out—in a single July afternoon. Salt mist, flooding tides, and palmetto bugs attack wiring daily. We counter with corrosion inhibitors, waterproof connectors, and rigorous cleaning of the screened vents designed to stand up to our coast’s hazards.
Transparent Service Area & Travel Policy
We cover Beaufort, Charleston, Myrtle Beach, and inland to Orangeburg. Projects more than 20 miles from our North Charleston PO Box include a flat $25 travel fee—clearly quoted before we roll.
