Not every tankless water heater problem announces itself with a dramatic failure. Many conditions develop gradually over successive heating seasons, going unnoticed until they compromise efficiency or cause unexpected downtime. Here are some warning signs that your tankless unit is due for professional maintenance:
A reduction in hot water volume or fluctuating temperatures during use are common indicators of mineral scale buildup inside the heat exchanger that is restricting flow and reducing heating efficiency. McQuillan Home Services can restore full performance with a professional descaling and flush service.
Error codes on a tankless unit frequently point to ignition failures, flow sensor issues, or venting obstructions that develop as a result of deferred maintenance. McQuillan Home Services can diagnose the specific code, address the underlying condition, and verify proper operation before leaving the premises.
Clicking, popping, or rumbling noises during operation often indicate mineral deposits within the heat exchanger or debris interfering with the burner assembly. McQuillan Home Services can identify the source of the noise and perform the appropriate cleaning or adjustment to restore quiet, reliable operation.
Most manufacturers and plumbing professionals recommend annual maintenance for tankless water heaters, particularly in areas with moderately hard water like the Twin Cities metro. McQuillan Home Services recommends scheduling service each year to address mineral accumulation and mechanical wear before either condition compromises unit performance.
Our team always provides upfront pricing with no hidden fees, so you know exactly what to expect before any work begins.

PROUDLY SERVING THE TWIN CITIES & SURROUNDING AREAS FOR OVER 135 YEARS
Most manufacturers and plumbing professionals recommend annual maintenance for tankless water heaters, particularly in areas with moderately hard water like the Twin Cities metro. Scheduling service once each year allows a technician to address mineral accumulation and mechanical wear before either condition compromises unit performance. Call McQuillan Home Services at (651) 292-0124 to schedule your maintenance.
A standard maintenance appointment includes descaling the heat exchanger, inspecting the burner and ignition assembly, verifying the venting system, and conducting a full operational performance test. These procedures collectively ensure that the unit continues to operate at its rated efficiency and within the safety parameters established by the manufacturer.
The water supply throughout much of the greater Twin Cities region carries a notable mineral content, which causes calcium and magnesium deposits to form within the heat exchanger over time. Without periodic flushing, this accumulation restricts water flow and forces the unit to work harder to achieve the set output temperature, ultimately shortening the equipment’s service life.
While homeowners can perform basic tasks such as cleaning the inlet filter screen, the core maintenance procedures require specialized flushing equipment, technical knowledge of combustion systems, and familiarity with manufacturer-specific service protocols. Engaging a licensed technician ensures that all components are properly inspected and that any warranty conditions tied to professional servicing remain intact. Contact McQuillan Home Services at (651) 292-0124 to schedule your service.
Indicators that a unit requires attention include a noticeable reduction in hot water output, fluctuating water temperature during use, unusual sounds during heating cycles, or error codes appearing on the unit’s display panel. Any of these conditions warrants a prompt service call, as they typically reflect the progressive effects of deferred maintenance rather than sudden component failure.
Consistent, professionally performed maintenance is among the most effective measures a homeowner can take to extend the operational lifespan of a tankless water heating system. Units that receive annual service routinely achieve or exceed the upper range of their expected service life, which in the case of quality tankless models can reach twenty years or longer.
The total cost of a residential tankless water heater maintenance visit varies based on the unit’s brand and model, the severity of mineral buildup, and whether any additional repairs are identified during the inspection. McQuillan Home Services provides detailed, upfront pricing before any work begins so homeowners can make informed decisions with full transparency. Call (651) 292-0124 to request your estimate.
