Our Commerce customers rely on us for all types of water heater repairs:

No Hot Water

Complete loss of hot water is the most common and urgent water heater problem:

Gas Water Heaters: No hot water from gas units typically results from pilot light failures, thermocouple problems, gas valve issues, or burner malfunctions. We diagnose the specific cause and perform appropriate repairs.

Electric Water Heaters: Electric units without hot water usually have failed heating elements, tripped circuit breakers, blown fuses, or thermostat failures. We test electrical components systematically to identify and fix the problem.

Tankless Water Heaters: Tankless systems that won’t produce hot water may have ignition failures, flow sensor problems, gas supply issues, or electronic control failures requiring specialized diagnosis and repair.

Insufficient Hot Water

When your water heater produces some hot water but not enough for normal use:

Sediment Buildup: Mineral deposits from Los Angeles’s hard water accumulate in tank bottoms, displacing water volume and insulating heating elements or burners from water. We flush tanks to remove sediment and restore capacity.

Failed Heating Elements: Electric water heaters with one failed element (most have two) produce less hot water than normal. We test and replace failed elements.

Undersized Units: If your household has grown or usage patterns changed, your existing water heater may simply be too small. We assess capacity needs and recommend appropriate sizing.

Thermostat Problems: Incorrectly set or malfunctioning thermostats prevent water from reaching desired temperatures. We calibrate or replace thermostats as needed.

Dip Tube Failure: The dip tube directs incoming cold water to the tank bottom for heating. When it breaks, cold water mixes with hot water at the top, reducing available hot water. We replace failed dip tubes.

Fluctuating Water Temperature

Water temperature that varies unpredictably indicates:

Thermostat Issues: Faulty thermostats cycle improperly, causing temperature fluctuations. We test, calibrate, or replace thermostats.

Heating Element Problems: Partially failed elements in electric heaters cause inconsistent heating. We test and replace failing elements.

Sediment Interference: Heavy sediment deposits cause uneven heating and temperature variations. Flushing resolves this problem.

Crossover Connections: Improperly installed mixing valves or crossed hot/cold connections cause temperature problems we diagnose and correct.

Strange Noises

Water heaters shouldn’t make loud or unusual sounds:

Popping or Rumbling: Sediment buildup on tank bottoms causes water trapped beneath to boil, creating popping sounds. Flushing eliminates sediment and noise.

Sizzling or Hissing: Water dripping onto hot burners or elements creates sizzling. This indicates leaks requiring immediate attention.

Screaming or Whistling: High-pitched sounds suggest restricted water flow, often from partially closed valves or sediment-clogged fixtures.

Hammering: Water hammer from pressure surges can damage water heaters and plumbing. We install arrestors to protect systems.

Water Heater Leaks

Leaking water heaters require immediate attention:

Tank Leaks: Leaks from the tank body itself indicate internal corrosion and tank failure requiring replacement. These cannot be repaired.

Pressure Relief Valve Leaks: Temperature and pressure (T&P) relief valves that leak may indicate excessive pressure, temperature, or valve failure. We diagnose and repair the cause.

Drain Valve Leaks: Leaking drain valves can often be tightened or replaced without replacing the entire unit.

Inlet/Outlet Connection Leaks: Loose or corroded connections at the top of the heater can be tightened or re-fitted to stop leaks.

Anode Rod Hole Leaks: After removing depleted anode rods, some tanks develop leaks at the opening. We can sometimes repair these; severe cases require replacement.

Rusty or Discolored Hot Water

Brown, rust-colored, or cloudy hot water suggests:

Failing Anode Rod: Anode rods protect tanks from corrosion. When depleted, tank interiors rust, discoloring water. We replace anode rods before tank failure occurs.

Corroded Tank Interior: Once tank interiors corrode significantly, water discoloration indicates impending failure requiring replacement.

Sediment Buildup: Heavy sediment creates cloudy or dirty water. Flushing often resolves this issue.

Foul-Smelling Hot Water

Hot water with sulfur or “rotten egg” odors indicates:

Bacteria Growth: Bacteria interact with anode rods creating hydrogen sulfide gas with characteristic sulfur smell. We replace standard anode rods with powered anode rods that prevent bacterial growth.

Contaminated Water Supply: Rarely, the problem originates in the water supply rather than the heater. We diagnose the source and recommend appropriate solutions.

High Energy Bills

Unexplained increases in gas or electric bills may indicate water heater problems:

Sediment Buildup: Sediment insulates water from heat sources, requiring more energy to heat water. Regular flushing maintains efficiency.

Failing Thermostats: Malfunctioning thermostats cycle improperly, wasting energy. We calibrate or replace thermostats.

Insufficient Insulation: Older water heaters lose heat through tank walls. We can add insulating blankets or recommend replacement with better-insulated modern units.

Undersized Units: Units too small for demand run constantly trying to keep up, wasting energy. Proper sizing improves efficiency.

We provide complete water heater installation services for all property types:

Traditional Tank Water Heaters

Gas Tank Water Heaters: We install natural gas and propane tank water heaters in sizes from 30 to 100+ gallons for residential and commercial applications. Installation includes proper venting (atmospherically vented or power-vented), gas line connections, seismic strapping (required in California), and pressure relief valve installation.

Electric Tank Water Heaters: Electric water heater installation includes proper electrical connections meeting code requirements, expansion tank installation where required, and complete system testing. We install units from 30 to 120+ gallons.

Tankless Water Heaters

Tankless (on-demand) water heaters provide endless hot water and energy savings:

Gas Tankless Units: We install indoor and outdoor gas tankless water heaters with proper venting, gas line sizing (often requiring upgrades), and condensate drainage where needed.

Electric Tankless Units: Whole-house electric tankless systems require significant electrical capacity. We verify service panel capacity and install appropriate units.

Point-of-Use Tankless: Small tankless units installed under sinks or near specific fixtures provide instant hot water without waiting. These are particularly useful in commercial settings or large homes.

Hybrid/Heat Pump Water Heaters

These high-efficiency units use heat pump technology to heat water using significantly less energy than traditional electric heaters. We install hybrid units where space and climate conditions are appropriate.

Commercial Water Heaters

Commerce businesses have specialized water heater needs:

High-Capacity Tank Systems: We install commercial-grade tank heaters from 50 to 120+ gallons for high-demand applications.

Multiple Unit Installations: Large facilities often need multiple water heaters working together. We design and install manifolded systems.

Commercial Tankless Systems: High-capacity commercial tankless units provide endless hot water for restaurants, hotels, and other high-demand businesses.

Recirculation Systems: Businesses requiring instant hot water at multiple locations benefit from recirculation pump systems we install and service.
