Our Team
Expert repair service for efficient, continuous hot water
Tankless water heaters are complex appliances with electronic controls, specialized heat exchangers, and precise flow sensors that require specific expertise to diagnose and repair correctly.
Our technicians have extensive experience with all major tankless brands and models, enabling them to quickly identify issues and implement effective repairs. From error code diagnosis to component replacement, we handle all aspects of tankless water heater repair with precision and care.
Benefits of professional tankless water heater repair
Restore efficient operation and energy savings
When tankless systems develop problems, they often consume more energy while delivering less consistent hot water. Professional repair restores the energy efficiency that likely motivated your tankless purchase in the first place.
After repairing flow sensors and descaling a heat exchanger for a Saratoga Springs family, they noticed an immediate 20% reduction in their gas bill along with more consistent water temperature.
Extend system lifespan and maximize your investment
With proper maintenance and timely repairs, a tankless water heater can last 15-20 years or more – significantly longer than traditional tank units. Professional repairs address issues before they cause cascading damage to multiple components, protecting your substantial investment in tankless technology. Many problems that seem serious can be resolved with targeted component repair at a fraction of replacement cost.
Address underlying causes, not just symptoms
Amateur repairs often treat symptoms without identifying the root cause, leading to recurring problems. Our diagnostic process identifies both the immediate issue and any contributing factors like water quality, installation problems, or maintenance needs. We recently repaired a unit in Eagle Mountain that had been “fixed” twice by another company but kept having the same problem – we discovered an improper venting configuration that was causing the recurring error codes and resolved it permanently.
Improve performance and reliability
Beyond simply fixing what’s broken, our repairs often improve overall system performance. Descaling heat exchangers, calibrating gas valves, and updating control firmware can enhance hot water delivery, temperature stability, and system efficiency. These improvements restore like-new performance that may have gradually declined so subtly you didn’t notice until after the repair was complete.

Advanced repair capabilities
These advanced capabilities mean we can repair most issues without default recommendations for complete replacement when targeted repairs would be more economical.

- Flow sensor cleaning and calibration
- Gas valve adjustment and replacement
- Ignition system repair
- Venting system correction
- Recirculation pump service

Comprehensive diagnostic process
Before attempting any repair, we conduct a thorough diagnostic process that identifies the specific issue affecting your system. This includes error code interpretation, electronic testing, gas pressure measurement, water flow testing, and visual inspection of critical components.
Same-day service for many repairs
We recognize that hot water is essential, not a luxury. For urgent problems, we prioritize same-day service whenever possible. Our technicians arrive with specialized tools and common replacement parts for major tankless brands, allowing them to complete many repairs during the initial visit.
Scale mitigation solutions
Scale buildup from Sandy’s hard water is the leading cause of tankless water heater problems in our area. During repairs, we can implement scale prevention solutions that protect your system from future damage.
Preventative maintenance during repairs
While addressing your immediate issue, we also perform preventative checks that identify potential future problems. This proactive approach often prevents additional service calls by addressing developing issues before they cause system failure.

When repairing a gas valve for a West Jordan homeowner, our technician also noticed scale beginning to affect the heat exchanger – addressing both issues at once prevented a likely breakdown just weeks later.

When to Schedule Tankless Water Heater Repairs in Sandy
A Spanish Fork family contacted us when their showers would suddenly go cold for 10-15 seconds before heating again – cleaning their clogged flow sensor completely resolved this irritating issue.
Error codes on the display panel
Modern tankless water heaters display specific error codes when problems occur.
Increasing energy bills
If your utility costs are rising without corresponding increases in hot water usage, your tankless system may be operating inefficiently.
Fluctuating water temperature
Inconsistent water temperature or sudden cold water “sandwiching” (brief bursts of cold water between hot) typically indicates flow sensor problems, scale buildup, or modulation issues.
Reduced hot water flow
When your tankless system delivers hot water at noticeably reduced pressure compared to cold water fixtures, internal scale buildup or flow restrictions are likely culprits.
System shutoffs during use
If your tankless unit frequently shuts down during operation, especially during high-demand periods, it may be experiencing overheating, flow problems, or sensor issues.
Ignition or combustion failures
Gas tankless systems that fail to ignite properly or make unusual combustion sounds need immediate professional assessment. These issues can stem from gas supply problems, ignition component failures, or venting restrictions.
Visible leaks or moisture
Any water leaking from a tankless unit requires immediate attention. While external connection leaks can often be repaired easily, internal leaks may indicate heat exchanger problems or other serious issues.
Unusual noises during operation
Strange sounds like excessive buzzing, rumbling, or whining often indicate pump problems, scale buildup affecting water flow, or fan issues in vented models.
When a Herriman homeowner noticed a small amount of water beneath their wall-mounted tankless unit, our inspection revealed a repairable connection issue that could have caused significant damage to their control board if left unaddressed.
