"It could not go better, I called at about 3:45pm, I had a new water heater by 6:30pm.  I wish the price was a bit lower but for the most part this was an emergency and they got the job done leaving the work area in better condition than they found it in, they were great!

"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

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

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.

Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. 

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.
