Power out? Electric utilities in the Charlotte area

• Duke Energy: Outages

Duke Energy serves Charlotte and much of Mecklenburg County. Some surrounding towns are served by a city utility or co-op instead. Use the outage page for the utility on your bill.

How Pool Helpline works in the Charlotte area

We're a video service, not a local pool company, and we don't have an office in the Charlotte area. You book a call, point your phone at the equipment pad (pump, filter, heater, salt cell and any display codes) and a real pool tech guides you by voice. Many problems can be diagnosed, and often fixed, in one call. If yours needs hands-on work, we'll help you find a local pro.

Flat prices, shown before you book: Quick Fix $49 · Full Diagnostic $89 · Priority Fix $139.

Power outage or a tripped breaker?

When the pump and the rest of the equipment go quiet in the Charlotte area, first work out whether it's the pool or the grid. If the neighbors and streetlights are out too, it's an outage: report it to your utility (links above). If everyone else has power, the problem is on your side, usually a tripped breaker or GFCI for the pool equipment. Reset it once. If it trips again, leave it off and call a licensed electrician (see pool light or electrical problem).

Anyone in the water who feels tingling, or a pool light flickering or on when it shouldn't be, is an emergency sign, not a repair to try: the U.S. Consumer Product Safety Commission says to get out of the water, turn off all power, and call 911 if someone may have been shocked. During an outage, SRP suggests turning off appliances so there's no surge when power returns; when it does, check that the pump primes and that the timer or automation clock didn't reset (see pump not priming).

Hot summers and freezing nights

NOAA's 1991-2020 climate normals for Charlotte Douglas International Airport put the average July high at 90.3°F, with about 49 days a year reaching 90°F, mostly from May through September. Heat and sun burn through chlorine, so test often: the CDC recommends a home pool pH of 7.0 to 7.8 with at least 1 ppm free chlorine (at least 2 ppm with stabilized chlorine such as trichlor tablets). If the water turns cloudy or green, a tech can walk you through it by video.

The same normals show about 58 nights a year at or below 32°F. The median first fall freeze is November 3 (as early as October 22 in one year in ten), and the median last spring freeze is March 30 (as late as April 14 in one year in ten). Moving water doesn't freeze easily, which is why Pentair's IntelliFlo3 pump guide says that in mild climates, when temporary freezing conditions may occur, you should run your filtering equipment all night, and warns not to rely on the pump's own freeze-protection "Thermal Mode" alone to protect the whole system. If the power goes out on a freezing night, report it to Duke Energy (above) and check for cracked pipes or housings before you restart (see pump not priming). Nearby Atlanta pool help faces a similar freeze window.

Opening and closing a Charlotte pool

If you close your pool for winter, plan to have it done before that early-November first freeze, and remember that a closed pool still needs its lines protected. When you open in spring, watch for a late freeze into March or early April before you shut off freeze protection. At start-up, a pump that won't catch prime or a heater that won't fire are the usual first problems (see pump not priming and heater won't fire).

Mecklenburg County pool barrier rules

Mecklenburg County Public Health requires approval before you build a residential pool, and you also need a building permit from the county's Land Use and Environmental Services Agency. The county's residential pool construction application says every outdoor residential pool must be completely fenced or protected once it can hold water. The minimum barrier under Appendix G of the North Carolina Residential Code is 48 inches high, with no opening greater than 4 inches through the barrier and no more than 2 inches of clearance under it. Gates must be self-closing and self-latching (and lockable where that applies); driveway gates that are part of the barrier need automatic self-closers. Towns around Charlotte set their own rules, so check with yours before changing a fence or gate.

Charlotte pool not working? Start here

• Pump not priming: Pump runs but the basket won't fill. Almost always air or water level.
• Heater won't fire: No heat, a flow or pressure code, or an ignition lockout. Flow comes first.
• Salt cell / chlorinator codes: No Flow, Check Salt, Inspect Cell and what the IntelliChlor LEDs mean.
• Green pool water: Green means chlorine ran out. Find out why so it doesn't come back.
• Electrical safety & pool lights: Tingling, flickering lights or a GFCI that won't reset. Treat it as an emergency.
• Need a replacement part? Send us your model and the old part's label, and a tech matches the exact part.
• Need someone on site? Tell us your ZIP code and we'll help you find a local pro.
