Tankless Water Heater Repair in Bloomington, MN

Specialized Tankless Expertise & Training

Tankless water heaters operate differently than storage tanks, with unique diagnostic requirements and technical challenges. Our technicians are trained specifically on on-demand systems, not just general plumbing. We understand the electronics, gas flow, water sensors and venting that make these systems tick, so we fix the right problem the first time.

Licensed, EPA-Certified Technicians

All our water heater service professionals hold EPA certification for handling refrigerant and gas systems safely. We’re held to exacting standards and trained on the latest tankless models. Your home deserves licensed professionals, not generalists.

Navien, Rheem & Multi-Brand Competence

We specialize in Navien systems, the industry leader in reliability and efficiency, and we also service Rheem, GE and other major tankless brands. Every manufacturer has unique control boards, sensors and failure modes — we know them all and carry the parts to fix them fast.

Family-Owned Reputation Built Over 48 Years

Three generations of our family have been fixing home systems in Bloomington. We’re still here tomorrow to stand behind the repair we do today. That’s not something you get from a big-box franchiser; it’s the difference of being your neighbour and your trusted contractor.

Upfront Diagnostics & Transparent Pricing

We’ll never sell you a repair you don’t need. When we visit, we test your system thoroughly using the proper diagnostic equipment, explain what’s gone wrong and why, and give you a clear quote before any work begins. If repair isn’t the best option, we’ll tell you that too.

Thorough Repair Warranty & Peace of Mind

Every repair includes written documentation of parts and labour, a warranty that covers what we fix, and our promise that if an issue arises, we make it right. Repairs are our accountability.

1. Comprehensive System Diagnostic & Testing

Our EPA-certified technician begins by listening to your problem, then systematically tests your entire system using specialized diagnostic tools designed for tankless units:

• Check the water inlet filter and flow rate to confirm adequate supply and pressure
• Test the flame sensor and ignition system to verify the burner operates
• Measure outlet water temperature and verify it matches your setpoint
• Inspect gas pressure at the appliance — insufficient supply is a common culprit
• Read any error codes and retrieve diagnostic data from the control board
• Examine the heat exchanger for scale buildup and check water quality
• Test electrical connections, circuit boards and sensor continuity

2. Diagnosis Report & Repair Options

Once we know what’s wrong, we sit down with you and explain the failure in clear language before any work begins. In this step we:

• Describe exactly what failed and why it happened — age, use, or poor water quality
• Provide an upfront estimate for the repair so you know the cost
• Explain whether repair or replacement makes more sense for your situation
• Discuss how to prevent similar issues in future, from water conditioning to a maintenance schedule
• Answer all your questions so you feel confident approving the work

3. Precision Repair Using Proper Parts & Techniques

For most failures, replacement of the failed component restores full hot-water delivery. Our technicians carry common parts and know the unique requirements of tankless systems:

• Replace failed heating elements, sensors or gas valves using OEM parts when required
• Clean mineral scale from the heat exchanger using approved descaling procedures
• Repair or replace water inlet filters and check for sediment damage
• Correct gas supply pressure and verify flame quality after the work is done
• Reseat or replace failed electrical connectors and circuit board components
• Test all safety shutoffs and pressure-relief mechanisms

4. Testing, Calibration & Performance Verification

After the repair, we run your system through a full test cycle to confirm it’s working reliably — not just that it turns on:

• Verify hot-water temperature matches your desired setpoint
• Confirm consistent temperature under variable flow conditions
• Test the system’s response to thermostat changes
• Check that all error codes have cleared and no new faults appear
• Listen for any remaining unusual noises during operation
• Inspect all connections and vents for leaks or damage

5. Documentation, Warranty & Maintenance Guidance

We close out every repair with clear paperwork and next steps so you’re never left guessing:

• Provide written records of all work performed and parts replaced
• Explain the warranty that applies to your specific repair
• Discuss regular maintenance needs and our maintenance plan options
• Share tips for extending your tankless heater’s lifespan
• Leave contact information for follow-up questions and support
