Water Heater Repair in Raleigh by ARC Plumbing

When your water heater quits, you want it handled today — not next week. Our Raleigh-based team offers same-day and emergency water heater repair for both gas and electric units. We diagnose the real problem first — a failed heating element, a bad thermostat, a worn anode rod, a faulty pilot or thermocouple — show you a flat-rate price up front, and fix it right. No pressure, no surprises, no trip charge to come take a look.

Water Heater Replacement & Installation

Sometimes a repair is throwing good money after bad. If your unit is 8–12 years old, leaking at the tank, producing rusty water, driving up your energy bill, or needing repair after repair, replacement is usually the smarter call — and we’ll tell you so honestly. We size the new unit to your household’s hot-water demand, install gas and electric models, and carry trusted brands. Not sure whether to stick with a tank or move to tankless? We’ll walk you through the trade-offs and the numbers before you decide.

Should You Go Tankless?

A tankless (on-demand) water heater gives you endless hot water, a lower energy bill, and back the floor space a bulky tank takes up. Tankless installs are one of our specialties — sizing and venting matter, and a good install is the whole ballgame. If you’re weighing it for your home, see our tankless water heater services page for the full breakdown, or ask for a free on-site quote and we’ll give you a straight answer.

Happy Clients

Bradley came out as scheduled and flushed out our tankless water heater! He also checked the water pressure and adjusted as needed. Very pleased with the job! Our technician was thorough and very knowledgeable! Great experience from the first call to final work! The staff is friendly and helpful! Thank you for all you do! We will definitely be contacting you for future work! Have a blessed year 2026!

Signs You Need Water Heater Repair or Replacement

If you’re seeing any of these, it’s worth a free on-site look before a small problem becomes a flooded floor.

No hot water, or it runs out far too quickly
Rusty, brown, or metallic-smelling hot water
Water pooling or dripping around the base of the tank
Popping, rumbling, or banging noises (usually sediment)
The unit is 10–12 years old or older
Energy bills creeping up for no clear reason

Common Water Heater Problems & Their Causes

Sediment buildup — minerals settle at the bottom of the tank, cause noise, and cut efficiency
Failed heating element or thermostat — the most common reason for “no hot water” on electric units
Corroded anode rod — once it’s spent, the tank itself starts to rust
Faulty pilot or thermocouple — a frequent culprit on gas units that won’t stay lit
Failed T&P (pressure-relief) valve — a safety issue worth addressing right away
Age and wear — most tanks simply reach the end of their life around 10–12 years

How to Get More Life From Your Water Heater

Have the tank flushed once a year to clear sediment
Check the anode rod every few years and replace it when it’s worn
Set the thermostat around 120°F — hot enough, easier on the tank, safer
Add an expansion tank if your home is on a closed system
Insulate older tanks and the first few feet of hot-water pipe
Schedule professional maintenance to catch small issues early

Now Installing the Essency EXR — A New Kind of Water Heater

Most homeowners only get two choices: a traditional tank or a tankless. ARC offers a third, cutting-edge option — the Essency EXR, the world’s first on-demand tank water heater. It pairs the steady, whole-home reliability of a tank with the efficiency of tankless: its SmartCore technology heats fresh water the moment you call for it, instead of burning energy to keep a tank hot 24/7.

Why it’s different:

Polymer tank — no rust, ever. There’s no metal in the tank to corrode, so no rusty water and no “rotten-egg” smell down the road.
No anode rod and no annual flushing. Water never sits stagnant, so the scale and sediment that kill ordinary tanks simply don’t build up.
Efficient on-demand electric heating — a great fit for homes where natural gas or a full tankless retrofit isn’t practical.

ARC is one of the few Triangle plumbers certified to install the Essency EXR. If you want the longest-lasting, lowest-maintenance water heater on the market, ask us whether the EXR is right for your home.
