Tankless Water Heater Repair

We Fix All Water Heater Types

Whether you have a traditional tank water heater, a newer tankless system, or a hybrid unit, our technicians know how to diagnose and repair the problem. We work on gas and electric models from all major manufacturers.

Many Westwood homes have older water heaters that just need the right repair to keep running efficiently for years. Others have tankless water heater systems that require specialized knowledge to service properly. We handle both situations with the same thorough approach.

You’ll also get honest advice about when a repair makes sense versus when replacement is the smarter choice. We’re not trying to sell you equipment you don’t need, but we won’t patch up a system that’s going to fail again next month either.

How do I know if my water heater needs repair or replacement?

If your water heater is less than 8-10 years old and the problem is something like a faulty heating element, thermostat, or minor leak, repair usually makes sense. Signs you might need replacement include the unit being over 12 years old, major tank corrosion, repeated breakdowns, or if repair costs approach 50% of replacement cost. We’ll give you an honest assessment of both options so you can make the right decision for your situation and budget.
The most common causes are failed heating elements in electric units, pilot light issues in gas units, or thermostat problems in both types. Sediment buildup can also reduce efficiency over time until you barely get lukewarm water. Tankless water heaters often have different issues like mineral buildup in the heat exchanger or ignition problems. Most of these problems are repairable if caught early, which is why quick diagnosis matters.
Most common repairs like replacing heating elements, thermostats, or pressure relief valves take 1-2 hours once we have the right parts. More complex issues like tank repairs or gas line work might take half a day. Tankless water heater repairs vary widely depending on the problem—some are quick fixes while others require more detailed work. We’ll give you a realistic time estimate before starting any work.
We repair both traditional tank water heaters and tankless systems from all major brands. Tankless units require different diagnostic tools and specialized knowledge, especially for issues like descaling, ignition problems, or error code troubleshooting. Our technicians stay current on training for both gas and electric tankless models. Whether it’s a conventional 40-gallon tank or a high-efficiency tankless unit, we have the expertise to get it working properly.
Turn off the power (breaker for electric units) or gas supply immediately, then shut off the water supply to the unit if you can locate the valve. Don’t ignore even small leaks—they typically get worse quickly and can cause water damage. Some leaks from pressure relief valves or connections are repairable, while tank leaks usually mean replacement is needed. Call us right away for emergency service, as water heater leaks can cause significant damage if left unaddressed.
Yes, we provide emergency water heater repair service because we understand that losing hot water can’t always wait until regular business hours. We prioritize emergency calls, especially during cold weather when the situation becomes more urgent. Emergency service is available for situations like major leaks, complete loss of hot water, or gas-related safety concerns. Our Dempsey Comfort Club members get priority scheduling for both emergency and routine service calls.
