"Part of the reason we chose them was a deal we saw on the website. However, when they came out to provide a quote, we didn't qualify. Just left a bad taste in my mouth and being able to trust any 'deals' being mentioned in the future. However the service and installation by the installer was excellent. Super nice and thorough. Water heater runs great."

"They arrived on time and in a VERY obvious hot pink van (pretty cool). Ken was courteous and answered my questions very clearly and quoted me a reasonable price... far less than I had been quoted by other companies. After a couple of hours, I had a new water heater. They left the work space tidy and I was able to pay right there on the spot with a card. I found out after speaking with the plumber that they are female owned and operated. BONUS!! I will definitely call these guys in the future should anything arise. Ladies, support this business!!"

"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

An average-sized empty water heater weighs around 150 pounds. Tankless water heaters are much lighter, weighing between 10 and 50 pounds. The smaller size and added convenience come at a price, though—tankless water heaters average about twice the price of their traditional counterparts.

If your water heater continues to have issues, you may wonder how long an electric water heat lasts. On average, these units last between 10 to 15 years. Following a proper maintenance schedule can help the water heater live to the end of its average lifespan or longer.

Yes, a water heater can be replaced in a day and can take between two and three hours to install from start to finish. Even if you encounter extra tasks that need to be completed, the job can still be completed in one day.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

Every type of water heater has its advantages and disadvantages. Understanding those can help you decide the best type for your situation and budget.
