"Current tankless water heater went down. Called and had a technician at my home within an hour. Technician quickly diagnosed issue. Based on the age of the unit I decided to upgrade to a new unit instead of repairing the old one. New unit was installed the following day. Professional and knowledgeable technician. Fast, friendly, quality service. I’d use them again in a heartbeat."

"My house water heater leaked after roughly 8 years and it was a Rheem Professional one (better than the home depot version according to the plumber who installed it) so I decided to replace it with a Bradford White one. I got sticker shock when I called the surrounding plumbers for quotes. In all cases, they wanted to stop by my house to check out and providing the quote. Luckily, my neighbor used Water Heater Pros a few months ago and told me about them. I went on the website and really like the fact that they listed the prices up front ( by far the lowest) with a list of stuff that will be installed with the water heater leaving no chance for confusion and/or misunderstanding. In addition, Water Heater Pros was listed at the top installer for Bradford White water heater at the main Bradford White website. I recalled the plumber who I ran into at Home Depot and installed my previous water told me that when he gave me the price for the installation (we met at the local Home Depot), he did not know where I live. If he knew where I live, the price would be double because plumbers know people who live in nice upscale subdivision can afford the higher price. This was/is terrible IMHO. In fact, when I asked him for a quote this time to replace my water heater, he did exactly that. No such issue with Water Heater Pros. I called Jim Brown (owner of the water heater pros) to schedule the service and was provided up front pricing with all the stuff needed to get done to fit the taller water heater into the same spot along with the Floodstop installation. Even with all of this, the price was still lower than all the quotes I got from local plumbers for just the water heater. Virgil and his crew mate showed up on Monday 10/17/2022 as schedule and about 30 minutes ahead of time. The two installers were very efficient and has all the tools needed to bring the big water heater into the attic without putting a scratch on the water heater itself. The last installer did not have any tool to bring the water heater up so they dragged it up the pull down ladder putting minor dent on the water heater. They was done within 3 hours including clean up and installed exactly all the pieces as they outlined on the website (new pan, ball valve, sediment trap and new gas flex line to replace the old one). I was/am very please with the installation and considered myself lucky to have found Water Heater Pros for hot water tank services. The key for me is up front and clear pricing without the complication of haggling with the plumbers to hopefully not being taken advantage of. Highly Recommended!"

"I just had David install a Rinnai tankless water heater and could not be more pleased. I had two other contractors give me bids, one stated he would have to do considerably more than what David had told me and attempted to sell me another tankless heater that wasn’t as good a day an install and purchase price about $500 more. The second contractor told me to get a standard water heater since everyone he talked with that got a tankless wanted to yank it out after a month since none of tankless heaters did what they said. In other words they didn’t know how to install this “Cadillac of tankless heaters”. David was very professional and installed the Rinnai in a few hours. I’d definitely recommend him, he knows more about these tankless system since his practice concentrated on this. I’m very happy with his quality work and you will be as well"

"Major leak under the slab of an older home ($40 a day in water leaking). They did a partial repipe to solve the issue without breaking the bank and also replaced a 19 year old water heater. They were quick and easy to work with. I appreciated most that they were able to come up with an affordable solution to my problem."

"I didnâ t have cash for a new water heater because I have already had several plumbing repairs lately. They gave me a good quote for the water heater and installation, got it approved for financing interest free, and had it installed in less than 3 hours!"

"They did a great job installing my new water heater. During the quotation they were very nice and helpful with suggestions and things to look out for. Then, they picked it up from Home Depot, completed the install, cleaned up, and even looked at another issue I had during the same visit. They were very nice throughout. Highly recommend."
