Yuri is a true professional and is a very knowledgeable expert about furnaces.I called him for advice when another well known Hvac company wrongly diagnosed my Trane furnace blower noise and told me I needed to undergo a $1500 repair. Yuri quickly assessed the problem and voila no more blower motor problems. All for $140!!Thank you Yuri! I highly recommend your service, honesty and expertise.

Water Heater Experts

Comprehensive Water Heater Maintenance Services

Annual Inspection and Tune-Up

Regular water heater tune-ups ensure efficient operation and safety compliance. We inspect burners, heating elements, venting, gas lines, thermostats, and electrical connections to prevent failures.

Sediment Removal and Flush

Flushing removes mineral deposits and sediment buildup that reduce heating efficiency. We perform full tank flushes to improve water flow, pressure regulation, and prevent heat exchanger clogging.

Thermostat Calibration

Incorrect thermostat settings cause fluctuating temperatures and energy waste. We calibrate thermostats, heating elements, and control panels for consistent hot water and optimized energy efficiency.

Pressure Relief Valve Testing

The T&P relief valve prevents dangerous pressure buildup. We test and adjust pressure settings, expansion tanks, and valve operation to ensure compliance with safety regulations.

Anode Rod Inspection

Anode rods prevent corrosion and rust inside the water heater tank. We check for magnesium or aluminum rod depletion and determine if replacement is needed to prolong system lifespan.

Anode Rod Replacement

A depleted anode rod leads to tank corrosion and leaks. We replace worn-out sacrificial rods with high-quality magnesium, aluminum, or zinc rods to protect your system and prevent premature failure.

Tank Inspection for Leaks and Corrosion

Leaks indicate internal corrosion, valve failure, or excess pressure. We inspect for tank deterioration, cracks, faulty connections, and rust buildup to ensure long-term system durability.

Gas Line and Burner Check

For gas water heaters, we inspect burners, pilot lights, thermocouples, and gas line fittings to ensure proper combustion, fuel efficiency, and carbon monoxide safety.

Electrical and Wiring Inspection

For electric water heaters, we check heating elements, circuit breakers, voltage supply, and wiring connections to prevent power failures, inefficiency, or overheating issues.

Warning Signs Your Water Heater Needs Maintenance

Fluctuating Water Temperatures

Inconsistent hot water indicates thermostat malfunctions, heating element failure, or sediment buildup. We inspect and adjust thermostats, dip tubes, and burner efficiency for stable temperatures.

Strange Noises

Rumbling, popping, or banging sounds signal sediment buildup, pressure fluctuations, or burner issues. We flush the tank, check the heat exchanger, and ensure proper T&P valve function.

Rusty or Discolored Water

Brown or rusty water means corroded pipes or a failing anode rod. We test magnesium or aluminum sacrificial rods, check for internal tank rust, and replace failing components to restore water quality.

Slow Hot Water Recovery

A delay in hot water production suggests heating element failure, burner inefficiency, or clogged dip tubes. We inspect gas valves, pilot assemblies, and tank insulation for optimal performance.

Leaks Near the Tank

Pooling water near the unit indicates valve failure, tank corrosion, or pressure buildup. We inspect T&P relief valves, expansion tanks, pipe fittings, and internal linings to prevent costly damage.

Bad Odors in Hot Water

A sulfur or rotten egg smell points to bacterial growth in the tank. We flush the system, replace anode rods, and use hydrogen peroxide treatments to eliminate contamination and restore clean water.

Low Hot Water Pressure

Reduced pressure may be due to sediment blockages, corroded pipes, or malfunctioning shutoff valves. We clear obstructions, adjust pressure regulators, and check plumbing connections.

High Energy Bills

A sudden increase in energy costs can mean heating inefficiency, thermostat malfunctions, or insulation issues. We optimize burner settings, heating elements, and energy-efficient thermostat calibration.

Expert Maintenance for Every Water Heater Type

Traditional Tank Water Heaters

We flush tanks to remove sediment buildup, inspect anode rods for corrosion, test T&P relief valves, and calibrate thermostats to maintain efficiency and prevent premature wear.

We perform heat exchanger descaling, inspect flow sensors and ignition systems, clean intake filters, and check venting systems to ensure continuous, energy-efficient hot water delivery.

Our maintenance includes cleaning the burner assembly, inspecting the gas valve, making pilot light adjustments, detecting carbon monoxide leaks, and ensuring proper combustion efficiency for safe operation.

We test and replace heating elements, check circuit breakers and wiring, calibrate thermostats, and inspect dip tubes and insulation to optimize heating performance and reduce energy waste.

We inspect heat pump components, refrigerant levels, and compressor efficiency and test backup heating elements for optimal energy savings, airflow, and consistent temperature control.

Frequently Asked Questions

What maintenance should you do on a water heater?

Routine maintenance includes flushing sediment, checking the anode rod, testing the pressure relief valve, inspecting gas or electrical components, and calibrating the thermostat for efficiency.

Yes, but improper flushing can damage components. A professional ensures complete sediment removal, valve safety testing, and proper system recalibration without risking leaks or inefficiencies.

Tank water heaters should be flushed once a year to prevent sediment buildup and efficiency loss. Tankless water heater require descaling every 12–18 months, especially in areas with hard water.

Signs include rumbling or banging noises, fluctuating water temperatures, reduced hot water supply, and increased energy bills due to poor heat transfer caused by mineral buildup.

Flushing removes calcium, lime, and debris. We drain the tank, clean the heat exchanger and dip tube, and ensure proper water flow and pressure for optimal heating performance.

A professional water heater flush typically costs $150 to $300, depending on tank size, sediment buildup, and system complexity. Regular maintenance prevents costly repairs.

Without maintenance, sediment buildup, rust, and faulty components reduce efficiency, increase energy bills, and shorten the unit’s lifespan, leading to expensive repairs or premature replacement.

Yes, tankless units need descaling to remove mineral deposits in the heat exchanger. Without regular maintenance, flow rate decreases, and energy consumption increases.

The T&P valve should release water when tested. If it drips continuously or fails to open, it may need replacement to prevent dangerous pressure buildup.

Yes! We provide same-day emergency maintenance for leaks, burner failures, pressure issues, and system malfunctions, ensuring your hot water supply is restored quickly.
