Extend Your Water Heater’s Life with Professional Maintenance in Marin County and San Francisco
Whether you have a gas, electric, tank, or tankless water heater, regular maintenance is the key to long-term performance and reliability. At Bay Air Heating & Cooling, we provide comprehensive water heater maintenance services.
Our licensed technicians follow industry best practices to ensure your water heater runs safely, efficiently, and in compliance with manufacturer warranty requirements.
What’s Included in Our Detailed Water Heater Maintenance Service
We perform a thorough, multi-point inspection and service that includes:
Critical safety device that prevents excess pressure buildup. We ensure the valve is not corroded, blocked, or leaking.
Protects the tank from rust by attracting corrosive elements. We inspect for deterioration and replace if more than 50% depleted.
Removes sediment, calcium, and rust that accumulate at the bottom. Improves heat transfer efficiency and extends tank life.
Maintains proper flow and heating efficiency in compact units. We also check for scale buildup and recommend descaling as needed.
Ensures accurate temperature settings and proper cycling. We test and replace worn-out elements in electric units if needed.
Checks for leaks, safe ignition, proper flame color, and combustion safety. Adjusts the gas valve and clears burner ports when needed.
Inspects wiring, breaker, and terminal connections for signs of overheating or failure.
Why Routine Water Heater Maintenance Matters
Investing in professional maintenance once a year can provide major benefits:
Benefit | Impact |
Extended Lifespan | Adds 2–5 years of use to most water heaters |
Lower Utility Bills | Increases heating efficiency and reduces standby heat loss |
Fewer Breakdowns | Early detection of wear or damage prevents costly emergency repairs |
Warranty Protection | Many manufacturers void warranties if annual maintenance is skipped |
Consistent Hot Water | Prevents inconsistent temperatures or premature hot water loss |
Improved Water Quality | Flushing removes rust, sediment, and mineral content that affect taste and clarity |
Tank vs. Tankless Maintenance – What’s the Difference?
Tank Water Heaters:
Require flushing at least once per year to prevent sediment buildup. Anode rod typically inspected every 1-2 years. TPR valve and thermostat checked for safety and temperature control.
Tankless Water Heaters:
Descaling and flushing every 12 months (more often with hard water). Filter screens and inlet ports cleaned to maintain optimal flow rate. Internal components inspected for mineral scale, especially in Marin homes with high calcium content. We tailor each visit based on your system type, water quality, and usage patterns.
Signs Your Water Heater Needs Maintenance
Don’t wait for a failure to act. If you notice any of the following, it’s time to call for service:
- Rumbling or banging noises (indicate sediment buildup)
- Rusty or cloudy hot water
- Slow hot water recovery
- Moisture or rust near the tank base or fittings
- Fluctuating water temperatures or short hot water supply
- Cold water despite the system being “on”
