Tankless Water Heater Repair

Every Type of Water Heater

Whether you have a traditional tank water heater or a modern tankless system, we handle both. Each type has its own quirks, and our technicians know them all.

Tank water heaters often fail due to heating element problems, thermostat issues, or sediment buildup. Tankless units typically have different challenges – mineral deposits, ignition problems, or venting issues. We carry parts for major brands and know which problems are worth fixing versus when replacement makes more sense.

In Wellesley’s older homes, we often see water heaters that have been patched together over the years. Sometimes the most honest advice is that you need a new unit. When that’s the case, we’ll tell you straight up and explain why.

How long does a typical water heater repair take?

Most water heater repairs are completed within 2-4 hours, depending on the problem and parts needed. Simple issues like replacing a heating element or thermostat often take less than an hour. More complex problems, like addressing sediment buildup or replacing multiple components, might take longer. We carry common parts on our trucks, so we can usually complete repairs the same day. If we need to order a specialty part, we’ll let you know upfront and work around your schedule for the follow-up visit.

Should I repair or replace my water heater?

It depends on the age of your unit and the cost of repairs. If your water heater is under 8 years old and the repair costs less than half the price of replacement, repair usually makes sense. For units over 10 years old, especially if you’ve had multiple repairs recently, replacement is often the smarter long-term choice. We’ll give you honest advice based on your specific situation. Sometimes a $200 repair buys you several more years. Other times, spending that money on an old unit just delays the inevitable replacement.

Do you work on tankless water heaters?

Yes, we service and repair all types of tankless water heaters, including gas and electric models from major manufacturers. Tankless units have different maintenance needs than traditional tank heaters – they’re more sensitive to mineral buildup and require regular descaling, especially in areas with hard water. Common tankless problems include ignition failures, error codes, and reduced hot water flow. Our technicians are trained on the diagnostic procedures and repair techniques specific to tankless systems, and we stock parts for the most common brands.

What causes water heaters to stop working suddenly?

Sudden water heater failures usually stem from a few common causes. Heating elements burn out, thermostats fail, or circuit breakers trip for electrical units. Gas water heaters might have pilot light problems, gas valve issues, or venting problems. Sometimes it’s as simple as a tripped reset button or blown fuse. Age plays a big role too – components wear out over time, and older units are more prone to sudden failures. Sediment buildup can also cause overheating and component failure. The good news is that most of these problems are fixable if caught quickly.

How much does water heater repair typically cost?

Water heater repair costs vary based on the specific problem and parts needed. Simple fixes like replacing a heating element or thermostat typically run $200-400. More involved repairs, like replacing gas valves or addressing multiple issues, can cost $400-800. We provide upfront pricing before starting any work, so you’ll know exactly what you’re paying. Emergency service calls may include additional fees, but we’ll explain all costs clearly. Sometimes the most cost-effective solution is replacement rather than expensive repairs on an old unit.

Do you offer emergency water heater repair service?

Yes, we provide emergency water heater repair service for situations that can’t wait until regular business hours. Complete loss of hot water, gas leaks, or water leaks that could cause property damage qualify as emergencies. We understand that hot water isn’t just a convenience – it’s essential for your daily routine and family’s comfort. Emergency calls may include additional service fees, but we’ll discuss all costs upfront. Our goal is to restore your hot water as quickly and safely as possible, even if that means working evenings or weekends.
