R. Davis Mechanical is proudly veteran owned and operated, bringing military precision and dedication to every tankless water heater maintenance service. We understand the importance of reliable systems and provide the thorough, professional service your home deserves.
Pittsburgh's water contains dissolved minerals, primarily calcium and magnesium, that precipitate out when water is heated. In tankless systems, water passes through a compact heat exchanger where it's rapidly heated to very high temperatures. This process accelerates mineral deposit formation.
Over time, mineral scale accumulates on heat exchanger surfaces, acting as an insulator between the heating elements and the water. This reduces heating efficiency, forcing the system to work harder and longer to achieve target temperatures. Eventually, scale buildup restricts water flow through the heat exchanger, triggering error codes and potentially causing permanent damage.
Without regular descaling, heat exchangers can develop such severe scale accumulation that they require replacement-an expensive repair that proper maintenance would have prevented. Based on our 15 years of experience servicing tankless systems in Pittsburgh, we've seen heat exchangers completely clogged with scale on systems that never received maintenance.
Our professional descaling service uses specialized pumps and solutions specifically formulated for tankless systems to remove mineral deposits without damaging sensitive components. This process restores heat exchanger efficiency and water flow to like-new condition, often with dramatic performance improvements.
Navien tankless water heaters use gas-fired burners that require clean combustion air and proper venting to operate safely and efficiently. Over time, dust and debris can accumulate on burners, flame sensors, and igniters, affecting performance.
Our maintenance service includes thorough combustion system cleaning and inspection, ensuring your tankless water heater operates safely and efficiently between service visits. We clean burners, flame sensors, and igniters while verifying proper flame patterns and combustion efficiency.
As technicians certified with Columbia Gas of Pennsylvania and Peoples Gas, we understand the importance of proper gas appliance operation. We perform comprehensive gas pressure testing, combustion analysis, and safety inspections to ensure your system operates safely.
Proper venting is critical for safe tankless water heater operation. We inspect intake and exhaust venting for blockages, deterioration, or improper installation. Our maintenance includes verification of adequate combustion air supply and proper exhaust gas venting.
Many tankless water heater warranties require proof of annual professional maintenance. Without maintenance records, warranty claims for heat exchanger failures or other problems may be denied. Our maintenance service includes documentation you need to maintain warranty coverage and protect your investment.
Our maintenance service includes complete documentation of all work performed, creating the service history required by most tankless water heater warranties. This documentation protects your investment and ensures you can exercise warranty rights if major components fail.
Skipping maintenance is what typically voids warranties, not proper professional service. Regular maintenance actually strengthens warranty coverage by demonstrating proper care and preventing problems that could lead to warranty disputes.
The cost of annual maintenance is minimal compared to the value of warranty protection. A single heat exchanger replacement can cost thousands of dollars-proper maintenance documentation ensures warranty coverage for such expensive repairs.
Regular maintenance keeps your tankless water heater operating at peak efficiency, delivering consistent hot water while minimizing energy costs. Our comprehensive service addresses all factors that affect system performance.
Clean heat exchangers and properly adjusted burners maintain maximum efficiency, reducing gas consumption and operating costs. Our maintenance service restores and maintains peak efficiency throughout the system's lifespan.
Proper maintenance ensures consistent water temperatures and reliable system activation. Clean sensors and calibrated controls deliver the steady performance you expect from your tankless water heater investment.
Regular descaling and filter cleaning maintain optimal water flow through the system, ensuring your tankless water heater can meet demand from multiple fixtures simultaneously without performance degradation.
Proper maintenance dramatically affects tankless water heater lifespan and long-term performance. While these systems are designed to last 15-20 years, neglected systems often fail within 7-10 years due to preventable scale damage.
Regular maintenance prevents heat exchanger damage, reduces component wear, maintains efficiency, catches problems early, and preserves warranty coverage. The cost of annual maintenance is minimal compared to premature system replacement.
Most Pittsburgh homeowners find that well-maintained tankless water heaters provide 15+ years of reliable service, while neglected systems often require major repairs or replacement within the first decade. Maintenance is an investment in long-term reliability.
Annual maintenance costs far less than heat exchanger replacement or complete system replacement. Over the system's lifespan, maintenance represents a small fraction of the total investment while providing years of additional reliable service.

We begin by reviewing your system's service history and testing current performance. This includes checking error code history, testing water temperature at multiple fixtures, and evaluating water flow rates. This initial assessment helps us understand how your system has been performing and identify any developing issues.
Descaling is the most critical maintenance task for tankless water heaters. We use specialized pumps and descaling solutions specifically formulated for tankless systems to remove mineral deposits without damaging sensitive components. This process restores heat exchanger efficiency and water flow to like-new condition.
With the system isolated for descaling, we remove and clean the inlet filter, removing any sediment or debris that's accumulated. We also clean the flame sensor, inspect the igniter for wear, and clean burners if needed. Clean filters ensure proper water flow and system activation.
After cleaning and descaling, we perform comprehensive combustion testing to verify safe, efficient operation. This includes gas pressure testing, burner flame inspection, combustion air verification, exhaust venting inspection, CO testing, gas connection inspection, and safety device testing.
Based on our experience servicing tankless water heaters throughout Pittsburgh, PA, we recommend annual professional maintenance for all systems. However, some situations call for more frequent service.
Most homes with moderate water hardness and average hot water usage benefit from annual maintenance scheduled in late summer or early fall-before peak hot water demand season but after summer usage. Annual service includes complete descaling, filter cleaning, combustion system inspection, and performance testing.
Consider semi-annual maintenance if your home has very hard water (over 10 grains per gallon hardness), the system serves a large family with high hot water usage, or you've experienced scale-related problems in the past. For homes with extremely hard water, quarterly maintenance may be necessary.
If your Navien tankless water heater hasn't been maintained regularly, the first service appointment may require extra time and attention to address accumulated scale buildup. In severe cases, multiple descaling treatments may be necessary to restore proper performance.
Between scheduled maintenance appointments, certain symptoms indicate your system needs service sooner rather than waiting for the next scheduled appointment. Don't ignore these warning signs-early intervention prevents minor maintenance issues from becoming major repair problems.
Lower pressure or volume from hot water fixtures suggests scale buildup restricting flow through the heat exchanger. This is often the first sign that descaling maintenance is overdue.
Inconsistent water temperatures indicate heat exchanger or flow sensor problems. Clean sensors and descaled heat exchangers provide steady, consistent temperatures.
Any error codes displayed on the system warrant professional evaluation. Many error codes relate to scale buildup, flow restrictions, or combustion issues that maintenance addresses.
