Our Water Heater Repair Process

Simple, Straightforward Service

First, we’ll ask you a few questions about what’s happening with your water heater. This helps us bring the right tools and parts on the first visit. We’ll schedule a time that works for you, often the same day for urgent situations.

When we arrive, we’ll thoroughly diagnose your system. We check everything—heating elements, thermostats, gas connections, venting, electrical components, and water pressure. No guessing, no assumptions. We find the actual problem before we start any work.

Once we know what’s wrong, we’ll explain it in plain English and give you upfront pricing. No surprises, no hidden fees. If you approve the repair, we’ll get to work using quality parts and proven techniques. We’ll test everything before we leave to make sure your hot water is working properly and consistently.

Everything You Need

Our water heater repair service covers both traditional tank systems and tankless units. We handle gas, electric, and hybrid models from all major manufacturers. Whether you need a simple thermostat replacement or complex heat exchanger repair, we have the expertise and parts to get it done.

We also provide honest guidance on repair versus replacement decisions. Sometimes a $200 repair makes perfect sense. Other times, you’re better off investing in a new, more efficient unit. We’ll give you the facts so you can make the right choice for your situation and budget.

For ongoing peace of mind, our Dempsey Comfort Club membership provides priority service, maintenance reminders, and exclusive discounts. It’s designed to help you avoid emergency breakdowns and keep your systems running efficiently year-round.

Most water heater repairs take 1-3 hours, depending on the problem. Simple issues like replacing a heating element or thermostat can be done in about an hour. More complex repairs involving gas lines, venting, or multiple components may take longer. We’ll give you a realistic timeframe once we diagnose the issue. Emergency repairs get priority scheduling, and we carry common parts on our trucks to avoid delays.
It depends on the age, condition, and repair cost. If your water heater is under 8 years old and the repair costs less than half the replacement price, repair usually makes sense. For units over 10 years old with major component failures, replacement is often more cost-effective long-term. We’ll assess your specific situation and give you honest recommendations based on the actual condition of your unit, not what we want to sell you.
Yes, we repair and service both traditional tank and tankless water heaters. Tankless units require specialized knowledge because they operate differently and have unique components like heat exchangers and flow sensors. We’re trained on the major tankless brands and carry the specific parts these systems need. Whether it’s a descaling service, sensor replacement, or heat exchanger repair, we handle it all.
The most common causes are sediment buildup, failed heating elements, faulty thermostats, and corrosion. In our area, hard water accelerates these problems by creating mineral deposits that reduce efficiency and damage components. Age is also a factor—most water heaters start having issues after 8-10 years. Regular maintenance can prevent many failures, but when problems do occur, quick professional repair prevents small issues from becoming major expensive ones.
Yes, we provide emergency water heater repair service for urgent situations. Complete loss of hot water, gas leaks, and water leaks qualify as emergencies. We understand that some water heater problems can’t wait, especially during winter months. Our emergency service includes evenings and weekends when needed. We’ll prioritize your call and work to restore your hot water as quickly as possible.
Regular maintenance is the best prevention. This includes annual flushing to remove sediment, checking the anode rod every 2-3 years, and testing the temperature relief valve. Keep the area around your water heater clear and watch for signs of trouble like unusual noises, inconsistent temperatures, or small leaks. Our Dempsey Comfort Club includes maintenance reminders and priority service to help you stay ahead of problems before they become expensive emergencies.
