"I left an email over the weekend for them to contact me, which they did on Monday morning. The scheduled someone to come the next day at 8:00am and completed the work. The work looks good, the work area was left clean, the old heater was removed, and it is as if no one had ever been there."

"With a dead water heater I needed to get it replaced right away. It was a Friday and many plumbers would not have been able to get here to replace it until Monday. I didn't want to go three days without any hot water. Quandt contacted right away after I had contacted Home Advisor and advised that they could have a plumber over to my house in about an hour. The price that he quoted was very reasonable. The plumber himself was very professional and pleasant to work with. He explained things about the installation that I was concerned with. He was very conscientious of many potential damage to my floor/carpeting while bringing in the new water heater and removing the old one. He was done with the project in about 1 1/2 hours. He did a great job and my wife was very pleased that she could take a shower that evening in our home. Quandt did a great job and I highly recommend them."

"I don't have anything to compare this to, but my 30ish year old furnace went out during a cold snap. DSP came out in the evening to diagnose it, explained my options (spend $1,400 on a repair or just replace the unit). The technician even brought back electric heaters for me to use overnight (it was about 9 pm at that point). They had a furnace in stock and they replaced mine in the next day. It is a year later and everything is working great. They have even come back one time to show me how to properly use my new thermostat. I am very pleased with their service and would not hesitate to call them again.

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet.  I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."

Water Heaters FAQs, answered by experts

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

A leaking water heater could potentially last for a few weeks or months before you need to repair it. However, it's not advisable to wait too long. Once your water heater starts leaking, it's likely that the underlying cause of the leak is getting worse as time goes on. Without immediate repair, your water heater could fail. Instead of using a leaky water heater, you should turn it off and call a pro to fix it.

Signs your electric water heater is failing include inconsistent water temperature, reduced hot water supply, longer heating times, or discolored water (rusty or cloudy). Unusual noises like popping or rumbling suggest sediment buildup, while leaks or corrosion around the tank signal structural damage. If your unit is over 10 to 15 years old and experiencing frequent issues, it may be time to replace it.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.
