A Lifesaving Maintenance Call Near Mesa Verde
About six months ago, we performed routine maintenance on a Rinnai tankless unit for a family living near Mesa Verde Elementary School. They had been religious about getting annual service, but this time our technician discovered something alarming during the inspection – the heat exchanger was showing signs of severe scaling despite the regular maintenance schedule. After discussing their water usage patterns, we realized their teenage kids had been taking much longer showers lately, forcing the unit to work harder and accelerate mineral buildup. We performed an intensive descaling treatment using our professional-grade circulation pumps and replaced the water filter that had become completely clogged. We recommended adding a pre-filter to help reduce the solids from Costa Mesa’s hard water. That small upgrade saved them from needing more frequent service and helped avoid a $1,200 heat exchanger replacement.

How Tankless Water Heater Maintenance Works
Professional tankless water heater maintenance begins with high-tech diagnostic equipment that can assess system performance and identify problems before they cause expensive damage. Our certified technicians use specialized digital meters to test gas pressures, water flow rates, and heat exchanger efficiency during every service visit.
The latest maintenance technology includes computer-controlled descaling pumps that circulate industrial-strength cleaning solutions through your heat exchanger to dissolve mineral deposits that reduce efficiency and damage internal components. We also use advanced filtration testing equipment to determine when water filters need replacement.
Our maintenance process includes thorough inspection of all venting components using digital cameras and airflow meters to ensure proper combusion air supply and exhaust gas removal. We clean intake air filters, test all safety systems, and verify proper operation of temperature and pressure sensors throughout the unit.
After completing maintenance, we conduct comprehensive performance testing using electronic diagnostic tools to verify optimal operation at all flow rates and temperature settings. The final step includes updating your system’s maintenance history and providing recommendations for preventing future problems.

Common DIY Tankless Maintenance Mistakes
Many Costa Mesa homeowners try to maintain their tankless water heaters themselves using online tutorials, but this often leads to expensive damage. The biggest mistake we see is people attempting to descale their units with regular household vinegar instead of proper descaling solutions. Vinegar isn’t strong enough to remove Costa Mesa’s heavy mineral deposits and can actually damage rubber seals and gaskets in the process.
Another dangerous mistake is neglecting to clean intake air filters regularly, which causes the unit to overheat and trigger safety shutdowns. We’ve seen several cases where clogged filters caused heat exchanger damage that could have been prevented with simple monthly cleaning.

- Monthly: DIY air filter cleaning and visual inspection
- Annually: Complete system tune-up and performance testing
- As needed: Water filter replacement (every 3-6 months)
Factors affecting frequency:
- Water hardness: Costa Mesa averages 15-20 grains per gallon (very hard)
- Usage patterns: Large families need more frequent service
- Unit age: Systems over 5 years need closer monitoring
Cost of regular maintenance: Twice-yearly service ($400-$640 annually) prevents major repairs ($800-$1,600) and extends unit life from 12-15 years to 20+ years.
Professional tankless maintenance is comprehensive and addresses Costa Mesa’s specific challenges:
Complete maintenance includes:

- Filter service: Clean/replace air and water filters
- Safety testing: Verify all sensors and safety systems function properly
- Performance optimization: Gas pressure and flow rate adjustments
- Venting inspection: Ensure proper combustion air and exhaust flow
Why descaling is critical: Orange County’s hard water creates scaling that:
- Blocks heat exchanger passages (reduces efficiency 25-40%)
- Damages temperature sensors and flow switches
- Causes overheating and premature component failure
- Triggers error codes and system shutdowns
Descaling process: Professional equipment circulates cleaning solutions through the system for 45-90 minutes, dissolving mineral deposits without damaging sensitive components.
Tankless maintenance costs vary by service level and frequency:
Maintenance cost breakdown:
- Basic annual service: $240-$380
- Complete descaling service: $320-$480
- Twice-yearly maintenance contract: $400-$640 annually
- Emergency diagnostic service: $300-$500
Consequences of skipping maintenance:
- Heat exchanger failure: $800-$1,600 replacement cost
- Reduced efficiency: 25-50% higher energy bills
- Shortened lifespan: 8-12 years vs 20+ with maintenance
- Frequent breakdowns: $200-$500 per service call

Cost comparison: Annual maintenance ($400-$640) vs major repair costs ($1,200-$2,400). According to manufacturer studies, properly maintained units last 60-70% longer and operate 30% more efficiently than neglected systems.
