These guys know their stuff. I'm in a condo and have a hydronic hybrid water/furnace hookup. (The water heater blows the warm air for the furnace.) My problem was when the heat was on I couldn't get hot water.

They came out, diagnosed the problem quickly as the mixing value, and fixed it for a reasonable price. Very happy to have hotter water than before even with the heat blowing.

The only negative (and why I gave it 4 stars) was that communication wasn't good. The receptionist could've sympathized with the problem more instead of giving short quick answers. More importantly, the gentleman didn't show the day he was going to come replace the mixing value. I had to call him. Came the next day though and did a great job at a good price, no added costs.

I would definitely recommend!

We were having continual problems with our Nortiz boiler/water heater that was suggested to be replaced only after 6 years of use . this was a new system with more than annual service. The technician that came out was friendly, efficient, and on time and figured out what was wrong and gave suggestions for our next maintenance to keep it running smoothly. He was knowledgeable about how the system works and it saved us thousands of dollars. I never realized how important it is to get a factory certified technician, and we will be having them do our annual maintenance for now on.

4.6 out of 5.0
James and Steve came out today and replaced my leaking old water heater with a brand new 50gal unit. In the window of 11am-1pm I was given, they arrived at 11:01, WIN! They were friendly, knowledgeable, and eager to help, DOUBLE WIN! We went over each cost point and actually reduced the price of the quote after seeing the situation. TRIPLE WIN! Install was complicated, being on a 4' tall platform, but they rigged a pulley system LIKE A BOSS and it was done in a couple hours. I made sure to thank them with a couple cokes and now I'm the proud owner of a new water heater. Couldn't ask for a better experience, and their price was nearly a thousand dollars less than the other quote I received.

It did take a bit of persistence on my end to get an appointment, but that's not worth a whole star, and I appreciated Jackie's help over the phone.

We had a mixing valve go bad on our 6 year old Eternal tankless. Bummer. I found out that Eternal has ""left the building"" and is no longer in business. Double bummer. I called WWH and they had the necessary part on their truck. Steve came over (when he should have been going home) and did a great job fixing the tank. We had been without hot water for 2 days, due to the weekend and are very thankful that this company could provide what we needed on such short notice. This is my go-to company. Thank you Steve!

We just replaced our hot water tank and after careful research, chose Washington Water Heaters. First of all, I called around for pricing and was impressed with them right away. Steve even came out to my house to talk about tankless options. In the end, he recommended just replacing old water heater due to our needs. The installer was out the very next day and he was excellent. Quality work and even included some extra plumbing we needed at no increase from the original price quote. He also cleaned up the area and was very professional the whole time he was here. I called several places before calling this company but so happy to have found this company. Excellence all the way around and I have complete confidence in them. Bonus: honest and best pricing too! I will be sharing their contact information with my neighbors and for anyone reading this review, search no further.

Steve was really helpful and wiling to teach us how to take care our water heater, tank and home. Not like other company so greedy, Steve try to help us save the money and give us the good suggestion and solution. The price is really reasonable (after we had several company to get us the estimate, we know). We are so thankful Steve's work and all the help.

I called around looking for someone to replace my water heater in a condo. I asked places about using a tankless system and many said it was just a bad idea, but Washington Water Heaters actually had a write-up on their site as to why electric tankless does not work for my situation and when I called they also explained in further detail.

So I decided to ask around again about having a regular tank system replaced. One place came out and quoted me at $2700. That was MUCH HIGHER than most ball-park over-the-phone estimates ($800-$1500) I was given.
So I went back to Washington Water Heaters and explained my situation. They gave me an expected ballpark value of $900, with possible incidentals costing another $200-$300. Rather than send someone out (and have to charge for that) they had me email pictures of the space and the water heater that was needing replacement (its 17 years old). I did that, had another short over-the-phone consult and then scheduled a tech to come out. Tom came out, assessed the situation and told me how much of those incidentals I'd be looking at. The price was right about what they estimated after they had seen the pictures I sent. Perfect!

Tom was friendly, even though my dog was super-nosy about some strange person hanging around the condo. He worked quickly and did a great job. Fair and honest...I feel like I found a great plumbing service.

There are very few companies that I bother to review. Washington Water Heaters is one of the good guys. The after installation service is excellent. We have had them install two tankless water heaters, a furnace and A/C unit. We really appreciate that they are will to go the extra mile. We highly recommend this group.

We are pleased with our new water heater and service from Washington Water Heaters. Our water heater blew and I received 3 quotes from different companies, which were all around the same $$, with the exception of an inflated quote from Aurora Plumbing. Our WWH tech Len was wonderful. This company is fair and honest and I would use them again AND recommend them to my friends and neighbors.
