Carolina storms, ice events, and grid outages don't give much warning. A properly installed whole-home generator kicks on within seconds of a power loss and keeps your lights, HVAC, refrigerator, and well pump running until utility power is restored. Total Plumbing Pros installs and services whole-home and standby generators across Mooresville, Charlotte, Lake Norman, and surrounding NC and SC communities.
We install all major brands — Generac, Kohler, Briggs & Stratton, Cummins — and handle everything from sizing and permits to the gas hookup, the automatic transfer switch, and annual maintenance. Whether you want whole-home backup or a smaller standby unit for essentials only, we size it right and install it safely.
Signs You Need Generator Installation & Hookup
FREQUENT OR EXTENDED OUTAGES IN YOUR AREA
If your neighborhood loses power more than once or twice a year, or outages routinely last hours, a generator pays back in convenience and peace of mind quickly.
WELL WATER OR SUMP PUMP DEPENDENCY
Homes on well water or with sump pumps lose more than lights during outages — they lose water and flood protection. A generator solves both.
MEDICAL EQUIPMENT IN THE HOME
CPAP machines, oxygen concentrators, refrigerated medications, and home dialysis equipment all depend on reliable power. A generator is real safety here, not a luxury.
WORK-FROM-HOME OR HOME BUSINESS
If your livelihood depends on staying online, a generator is straightforward business insurance against outages that would otherwise cost you a day of work.
