Tankless Water Heater Repair in Brunswick County
Certified Diagnostics for Coastal NC Homes & Vacation Properties
Tankless water heaters fail differently than tank units, and a generic repair approach often misses the real problem. At A+ Heating & Cooling – Electrical, our certified technicians run a full diagnostic before recommending any repair, then show you the complete price before a single wrench turns. That’s true whether the call comes in on a Tuesday afternoon or a Sunday night.
Our One Call. One Company. model means your water heater, HVAC system, and electrical needs are all handled under one roof. No coordinating between separate contractors, and no extra fees for emergencies, evenings, or weekends.
When your tankless water heater stops delivering, we’re available 24/7 to diagnose and repair it. Call us at (910) 600-6025 to schedule service in Brunswick County, NC.
Signs Your Tankless Water Heater Needs Repair
Tankless units give fairly clear signals when something is wrong. Knowing what to look for helps you describe the problem accurately and address the issue faster.
- No hot water or inconsistent temperature: If the unit runs but water stays cold or fluctuates unpredictably, the issue could be anywhere from the flow sensor to the heat exchanger.
- Cold water sandwich: A brief burst of hot water followed by a slug of cold water, then hot water again. It’s most noticeable when hot water is turned off and back on quickly, and it often points to a buffer or flow issue within the unit.
- Ignition failure: The unit fires but doesn’t stay lit, or won’t ignite at all. Common causes include a closed gas valve, a failing igniter, or a dirty flame sensor.
- Error codes on the display: Modern tankless units flag ignition, airflow, temperature, and flow sensor faults with specific codes. Our technicians read those codes as the starting point for every diagnostic.
- Rumbling or popping sounds: These typically point to mineral and scale buildup inside the heat exchanger. Left unaddressed, scale reduces efficiency and can trigger overheating shutdowns.

Fast, friendly, and fair prices. We bought a new HVAC unit from Costco and they contracted A+. I was happy with the installation in 2019, and again today with a quick repair.

Kathleen A. -
"The service at A+ is always impeccable!"
Our tech came out but we didn't hear the phone upon his arrival. When we realized we had missed the call we called and customer service informed us that he had come out, checked the outside unit, and found and repaired the issue.
