What's Included in Every Service

Every water heater repair includes a full system diagnostic, not just a quick look at the obvious problem. We check safety features, test water pressure, inspect venting systems, and verify proper electrical or gas connections. This prevents future breakdowns and keeps your system running safely.

You get professional-grade parts when replacements are needed. We don’t use cheap components that’ll fail in six months. Our parts come with manufacturer warranties, and our labor is guaranteed too.

We also handle both traditional tank water heaters and tankless systems. Whether you’ve got a 10-year-old tank unit or a newer tankless water heater, our technicians have the experience and tools to fix it properly. We can also help you understand your options if it’s time to upgrade to a more efficient system that’ll save you money on energy costs.

How long does a typical water heater repair take?

Most water heater repairs take between 1-3 hours, depending on what’s wrong. Simple issues like a faulty heating element or thermostat can often be fixed within an hour. More complex problems like gas valve replacement or extensive electrical work might take longer. We’ll give you a realistic timeframe after we diagnose the problem. If we need to order a specific part, we’ll let you know upfront and work with you to schedule the completion as soon as possible.

Should I repair my old water heater or replace it?

It depends on your water heater’s age, condition, and repair costs. If your unit is under 8 years old and the repair costs less than half of a replacement, repair usually makes sense. For water heaters over 10 years old with major component failures, replacement often saves you money long-term through better efficiency and fewer future repairs. We’ll assess your specific situation and give you honest recommendations based on repair costs versus replacement benefits, including potential energy savings.

Do you service tankless water heaters too?

Yes, we repair and service both traditional tank water heaters and tankless systems. Tankless units have different components and diagnostic requirements, but our technicians are trained on all major tankless brands. Common tankless repairs include descaling, replacing heating elements, fixing error codes, and addressing flow sensor issues. We carry parts for most tankless systems and can handle both gas and electric models. Tankless repairs sometimes require specialized tools, which we have on our service trucks.

What if my water heater breaks after hours or on weekends?

We offer emergency water heater repair service for situations that can’t wait until regular business hours. This includes complete loss of hot water, gas leaks, or water heater leaks that could cause property damage. Emergency service does include additional fees, but we’ll explain all costs upfront. For non-emergency issues, like reduced hot water output, scheduling during regular hours usually saves you money and gets the same quality repair work.

How much does water heater repair typically cost?

Water heater repair costs vary based on what needs to be fixed. Simple repairs like thermostat replacement typically cost less than major component failures like heat exchanger issues. We provide upfront pricing after diagnosing the problem, so you’ll know the exact cost before any work begins. Most repairs fall between basic service calls for minor adjustments and more extensive repairs for major component replacement. We’ll also let you know if repair costs approach replacement territory so you can make an informed decision.

How can I prevent future water heater problems?

Regular maintenance prevents most water heater breakdowns. This includes annual flushing to remove sediment buildup, checking and replacing anode rods every 3-5 years, and testing safety features like temperature and pressure relief valves. For tankless units, annual descaling prevents mineral buildup that causes efficiency problems. We can show you basic maintenance tasks you can handle yourself and recommend when to schedule professional service. Proper maintenance typically extends water heater life by several years and prevents emergency breakdowns.
