Stepping into a cold shower is a rough way to start the day. Before you assume your water heater is dead, run through these checks — a few of them are simple fixes you can do in minutes.
If none of them bring the heat back, it's time to call. But it's worth two minutes to rule out the easy stuff.
1. Gas heater: check the pilot light
On a gas water heater, look through the sight glass near the burner. No flame means the pilot is out. Follow the relight instructions on the tank's label. If it won't stay lit, the thermocouple may be failing — a common, repairable fault.
2. Electric heater: check the breaker
On an electric unit, check your panel for a tripped breaker and reset it. If it trips again immediately, stop — that points to an electrical fault or a shorted element that needs a pro.
3. Look for a leak
Water pooling around the base means a leaking tank, which can't be repaired. Shut off the water to the heater and call — this is the one that can flood a garage. See emergency water heater service.
4. Check the thermostat setting
It sounds obvious, but settings get bumped. The sweet spot is around 120°F. If someone turned it down (or to 'vacation'), turn it back up and give it 30–45 minutes.
5. Consider whether you just ran out
Back-to-back showers and a load of hot laundry can drain a tank faster than it reheats — especially an undersized or sediment-filled one. If hot water returns after an hour, you may simply have outgrown your tank.
6. Listen for popping or rumbling
Those sounds are hard-water sediment cooking at the bottom of the tank. It makes the heater work harder and shortens its life — a big reason Las Vegas water heaters fail early. A flush helps; a failing tank may need replacement.
7. Check the age of the unit
Find the manufacture date on the label. In our hard water, many tanks give out at 6–8 years. If yours is past that and struggling, repairs get less worthwhile and a new (or tankless) unit is the smarter spend.
In cooler months this is one of the most common calls we get across Henderson and the valley — and one we can often solve same-day.
When it's time to replace instead of repair
Some no-hot-water calls are a cheap fix — a thermocouple, a heating element, a thermostat. But there's a point where pouring money into an old tank stops making sense.
If your heater is past 8–10 years, has a leaking tank, or needs a second repair inside a year, replacement is usually the smarter spend — and it's a chance to size the tank to your actual demand or switch to a tankless unit for endless hot water. We'll lay out the repair cost against a replacement honestly, so you're not sinking money into a heater with a year left.

Frequently asked questions
Is no hot water an emergency?
It can be, especially in winter or if the tank is leaking. If you smell gas, see water pooling, or a breaker keeps tripping, treat it as urgent and call right away.
How quickly can you restore hot water?
Many no-hot-water calls are a same-day fix — a heating element, thermocouple or thermostat. If the tank has failed, we offer same-day replacement too. Call (614) 830-0578.
Is it worth repairing an old water heater, or should I replace it?
Under about 8 years with a simple fault, repair. Past that — or with a leaking tank, or a second failure in a year — replacement usually wins, because our hard water is already thinning the tank from the inside. We'll give you both numbers and an honest recommendation rather than defaulting to the bigger job.
The bottom line
Run the seven checks — pilot, breaker, leak, thermostat, demand, sediment, age. If hot water doesn't come back, we'll get it sorted fast, whether that's a quick repair or a same-day replacement.
