Common Tankless Water Heater Repairs We Handle in Coquitlam
Our team is equipped to handle a full range of tankless water heater repairs, including:
Heat Exchanger Repairs & Replacement
The heat exchanger is the core of your tankless system. If it’s cracked, scaled, or failing, your unit won’t heat water effectively. We assess whether a repair or replacement is the right call for your situation.
Flow Sensor & Pressure Relief Valve Repair
A faulty flow sensor can prevent your unit from recognizing when water is being drawn, causing cold water or ignition issues. We test, clean, and replace sensors as needed.
Gas Valve & Ignition System Repair
Ignition failures are one of the most common tankless water heater complaints. Our gas-certified technicians diagnose and repair gas valve issues, igniters, and flame sensors safely and to code.
Venting & Exhaust Issues
Improper or blocked venting can trigger safety shutoffs and cause carbon monoxide risks. We inspect and repair venting configurations to ensure your system is safe and efficient.
Error Code Diagnosis
Every brand has its own fault code system. We carry manufacturer documentation and have hands-on experience with Navien, Rinnai, Noritz, Rheem, Bosch, and others to get to the root of the issue quickly.
Scale & Mineral Buildup Removal
Coquitlam’s water supply can leave mineral deposits inside your tankless unit over time. We perform descaling service to restore heat transfer efficiency and extend unit life.

Frequently Asked Questions About Tankless Water Heater Repair in Coquitlam
How do I know if my tankless water heater needs repair or replacement?
Generally, if your unit is under 10–12 years old and the repair cost is less than 50% of a new unit, repair is usually the smarter investment. Our technicians will assess the overall condition of your system and give you an honest recommendation either way. We also install new tankless units if a replacement is the right call – you can learn more on our Tankless Water Heater Installation page.
How long does a tankless water heater repair typically take?
Most repairs are completed in a single visit – usually 1 to 3 hours depending on the issue. If a specific part needs to be ordered, we’ll let you know the timeline upfront and work to source it as quickly as possible.
Do you repair both gas and electric tankless water heaters?
Yes. We service both natural gas and electric tankless units. Our technicians are certified for gas work in BC and are experienced with electric systems as well.
What brands of tankless water heaters do you repair?
We repair all major brands including Navien, Rinnai, Noritz, Rheem, Bosch, Bradford White, and more. If you’re unsure whether we service your brand, just give us a call.
Is it worth repairing an older tankless water heater?
It depends on the age of the unit, the nature of the problem, and the cost of the repair. Tankless water heaters typically last 15–20 years with proper maintenance. We’ll give you a straightforward assessment so you can make the right decision for your home and budget.
Do you offer any warranty on repairs?
Yes. We stand behind our work. Ask us about our labour warranty when you book – we want every repair to be one you feel confident about.

Signs Your Tankless Water Heater Needs Repair
Don’t wait for a complete breakdown. If you’re noticing any of the following, it’s time to call a pro:
- No hot water or inconsistent temperatures – Your unit is firing but not delivering, or water temperature fluctuates unexpectedly during use.
- Error or fault codes on the display – Modern tankless units flag problems with codes. Our technicians can interpret and resolve these quickly.
- Unusual noises – Banging, hissing, or rumbling sounds often indicate mineral buildup, a failing component, or a venting issue.
- Ignition failure – The unit attempts to start but won’t fire, leaving you with cold water only.
- Low water pressure from hot taps – Can indicate a flow sensor issue or internal blockage.
- Water leaks around the unit – Even small leaks can signal a cracked heat exchanger or loose fitting that needs immediate attention.
- Pilot light keeps going out (gas units) – Points to a thermocouple or gas valve issue.
- Surging or fluctuating flame – Often a sign of gas supply or pressure problems.
If you’re experiencing any of these issues in Coquitlam or the surrounding Tri-Cities area, give us a call. We’ll send a technician out to diagnose the problem fast.
