Traditional and Tankless System Expertise

We handle every type of water heater system you’ll find in Rochester homes. Traditional tank units, tankless systems, electric, gas – our technicians have the training and tools for all of them.

Your service includes thorough system inspection, not just a quick fix. We check for underlying issues that could cause problems later, like sediment buildup, corrosion, or ventilation problems that affect performance.

You also get honest advice about repair versus replacement. Sometimes a repair makes perfect sense. Sometimes you’re throwing money at a system that’s going to fail again soon. We’ll tell you which situation you’re in and why.

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

Age is the biggest factor. Most traditional water heaters last 8-12 years, while tankless units can go 15-20 years with proper maintenance. If your unit is approaching these ages and having frequent problems, replacement usually makes more sense financially. However, newer systems with isolated issues like a faulty thermostat or heating element are often worth repairing. We’ll assess your specific situation and give you honest recommendations based on the system’s condition, repair costs, and your long-term needs.

What are the most common water heater problems in Rochester homes?

Sediment buildup is huge here because of our hard water conditions. It reduces efficiency and can cause complete failure if not addressed. Heating element failures are also common, especially in electric units that work harder during our cold winters. Thermostat issues cause inconsistent water temperature, and anode rod corrosion leads to tank leaks in older systems. We also see a lot of pilot light problems in gas units and pressure relief valve issues. Most of these problems are fixable if caught early, which is why regular maintenance matters.

How long does a typical water heater repair take?

Most repairs are completed within 2-4 hours, depending on the issue and parts availability. Simple fixes like thermostat replacement or heating element swaps are usually done in under two hours. More complex problems involving multiple components or hard-to-reach areas might take longer. We carry common parts on our trucks, so we can complete most repairs the same day. If we need to order a specific part, we’ll let you know upfront and work with you to minimize the inconvenience while we wait for it to arrive.

Should I attempt any water heater repairs myself?

No, and here’s why: water heaters involve electricity, gas lines, and high-pressure water systems. A mistake can cause serious injury, property damage, or carbon monoxide issues with gas units. Plus, DIY repairs often void manufacturer warranties and can create bigger problems that cost more to fix later. Even simple-looking issues like replacing a heating element require proper tools, safety knowledge, and understanding of electrical systems. Save yourself the risk and potential expense of making things worse. Professional repair is always the safer, smarter choice.

What should I do if my water heater is leaking?

Turn off the power supply immediately – flip the breaker for electric units or turn off the gas for gas units. Then shut off the water supply using the valve at the top of the tank. If water is actively leaking, try to contain it with towels or buckets to prevent property damage. Don’t ignore small leaks thinking they’ll stop on their own – they always get worse. The location of the leak matters: leaks from the top connections might be repairable, but leaks from the tank bottom usually mean replacement is needed. Call us right away because water damage gets expensive fast.

How can I prevent future water heater problems?

Annual maintenance is your best defense, especially with our hard water conditions. This includes flushing the tank to remove sediment buildup, checking the anode rod for corrosion, and testing the pressure relief valve. Keep the area around your water heater clear and watch for early warning signs like inconsistent temperatures, strange noises, or rusty water. For gas units, ensure proper ventilation and never store flammable materials nearby. Our Dempsey Comfort Club members get regular maintenance that catches problems before they become expensive emergencies. It’s much cheaper to maintain your system than replace it prematurely.
