Full-Service Water Heater Support

We repair all major water heater brands and types, from traditional tank units to high-efficiency tankless systems. Whether it’s a heating element failure, thermostat issue, or gas valve problem, we have the parts and expertise to fix it properly.

For older units that are beyond economical repair, we also handle complete water heater replacement with energy-efficient models that can actually lower your utility bills. Many Hanover homeowners are surprised how much they can save by upgrading from a 15-year-old inefficient unit.

We also offer preventive maintenance through our Dempsey Comfort Club, which helps catch small problems before they turn into emergency breakdowns. Regular maintenance extends the life of your water heater and keeps it running at peak efficiency.

How long does a typical water heater repair take?

Most water heater repairs in Hanover take 1-3 hours once we arrive and diagnose the problem. Simple fixes like replacing a heating element or thermostat usually get done within an hour. More complex issues involving gas lines or major component replacement might take longer, but we’ll give you a clear timeframe upfront. The majority of our water heater service calls get completed the same day, so you’re not waiting around for hot water.

What are the most common water heater problems in this area?

In Hanover and Plymouth County, we see a lot of heating element failures due to hard water mineral buildup, especially in older tank units. Thermostat problems are also common, particularly after power outages or electrical surges. During winter months, we get calls for gas water heaters with venting issues caused by ice or debris. Tankless units sometimes develop scale buildup that affects performance. Most of these problems are fixable without replacing the entire unit, as long as you catch them before they cause secondary damage.

Should I repair or replace my water heater?

If your water heater is under 8 years old and the repair cost is under half the replacement cost, repair usually makes sense. For units over 12 years old, replacement often provides better long-term value, especially if you’re dealing with multiple problems or declining efficiency. We’ll give you honest guidance based on your specific situation. Sometimes a $200 repair on a 15-year-old unit just delays the inevitable, while other times a simple fix gives you several more years of reliable service.

Do you service tankless water heaters?

Yes, we repair and maintain all major tankless water heater brands including Rinnai, Navien, Rheem, and Bosch. Tankless units require different expertise than traditional tank water heaters, particularly for gas line sizing, venting, and descaling procedures. We handle everything from simple maintenance flushes to complex repairs involving heat exchangers or gas valves. Many tankless problems in this area stem from hard water scale buildup, which we can resolve with proper descaling and water treatment recommendations.

What's included in your water heater service call?

Our service call includes complete system diagnosis, clear explanation of any problems we find, and upfront pricing for recommended repairs. We test all safety systems, check for proper venting and gas connections, examine electrical components, and assess overall unit condition. You get a full report on what’s working, what needs attention, and what you can expect going forward. There’s no charge for the diagnostic if you proceed with our recommended repair work.

Do you offer emergency water heater repair service?

Yes, we provide same-day emergency water heater repair throughout Hanover and Plymouth County. We understand that losing hot water isn’t something you can put off, especially during winter months. Our emergency service covers evenings and weekends when other companies aren’t available. We stock common parts on our trucks so most emergency repairs get completed without waiting for special orders. Emergency service does include additional fees, but we’ll explain all costs upfront before starting any work.
