On call water heater saved our Christmas ! We had no hot water and nobody could do the job until after Christmas. They were able to to schedule service right away. Natalia explained everything and was very patient their prices were reasonable everyone else wanted to take advantage due to the holiday they're very ethical. Oscar our installer did an excellent job informing us of his arrival status. I would absolutely recommend them for any water heater service!! read more

Stay Away from this business!! This review is for a replacement install of our old tankless water heater and the subsequent experience we had a few months later when the brand new one they installed broke and their complete lack of managing the situation. In short...the company completed fraudulent work, installed a unit not meant for the exterior of our home (unit installed did not match the invoice provided), and it was not installed per manufacturer's specifications and it was not up to code, resulting in the possibility of damage, fire or other issues to our home and family. Because of OnCall Water Heaters and Natalia's horrendous customer service, we were without any hot water for more than 5 days as a family of 5 with young infants in the middle of January. They had many opportunities to do the right thing and never followed through. Ultimately, I disputed the charge through my credit card company and they reversed the charge for me, had they not I would have been taking them to small claims court. Here's more info: -the invoice for the initial install (replacement of our 20yr old tankless H2O heater) did not match the product they installed in August 2023. -H2O heater broke in January of 2024, called them and they came out to look at it, could not repair that day and called a rep from the manufacturer - AOSmith, who came out to take a look. -The rep's initial reaction was "This is installed completely wrong, they installed a water line for half of the gas line with a connector that was corroding after only 3.5mo; the unit they installed was meant for the interior of the home (as evidenced by the serial #), and they connected it to an old existing exhaust duct (as that would be needed inside the home and the unit has large hole on top of it to accomodate), but the hole and the duct work were different diameters so it has been acting as a funnel for rain water and other elements to enter the unit. I have rarely seen work this terrible and incorrect." The rep was also told to "not tell the homeowner anything", and to his credit, he did inform us as he would want someone to do the same for him if it was his home. -I immediately called Natalia (at OnCall) and she indicated that they would fix it, and ultimately replace the unit for one that was meant for the exterior of the home. -A week of back and forth ("we'll come back out to fix it; we'll have the rep from AOSmith fix the exiesting unit so you have hot water and then in two weeks we'll replace the unit; My dad will come and take a look, he is the best; the rep's estimate is too high, he is price-gouging you and we won't pay him"). -And when I expressed frustration after 5 days of no-hot water and no resolution in sight, and began indicating that I wanted a refund if they were not going to fix the situation immediately, then Natalia started making excuse after excuse, "her son was in a accident and he may have killed someone; we have a lot going on". I can have compassion as a human being for another and still ask for accountability of the company to make right a situation that they created in the first place. Natalia seemed to consider offering a refund if I agreed to not write a negative review, however I said that if I were given a refund, my review would be factual and include that the company ultimately did something to make it right, but that I felt that other future customers had the right to hear my experience overall. Ultimately, Friday afternoon, I called another company to inquire about the cost of installing a replacement as I was getting nowhere with OnCall. When I sent pictures of the installation to the new company, they echoed exactly what the rep had said regarding the horrendous, fraudulent work, noted safety concerns and gave me the same pricing on a repair that the rep had. In essence, getting two second opinions that matched. The new company was able to come out the following morning and remove the broken unit, install a new one of high quality and he had hot water within 14 hours of calling them. Natalia texted that same morning a very long ranting that was trying to cover her tracks - too little too late. I submitted a heap of evidence to my credit card company (timeline, all text message exchanges, photos, etc.) in support of my claim that I should not have to pay OnCall for their shotty and fraudulent work. What an awful experience that truly took up WAAAYYYYY too much of my time. read more

Amazing company and amazing service! Natalia was like dealing with a family member or something.

Positive experience with On Call Water Heaters Natalia did great working around my schedule because my water heater is in my neighbor's garage and we had to make arrangements for both of us be around during the installation. Plumbing in my condo complex is unique to say the least. Oscar, the technician, was very professional, communicative, completed the installation under an hour, and left the garage clean. He also assured me there would be no more further issues but if there was, just to call him back and he'd return promptly. The best part, Natalia gave me the best quote for what I needed and they discarded my old water heater. Thank you Martha for referring On Call Water Heaters to me! They are definitely now on my list to refer out to my family and friends. read more

Highly recommended! I went with On Call Water Heaters to get a new water heater and add an expansion tank. Natalia is great to communicate with and very responsive. She worked with me to get the exact water heater I wanted and at a great price. I had complicated piping around my water heater and the technician knew exactly what to do and completed the job well. He also patiently answered all my questions. Thank you On Call Water Heaters! read more

On Call Water Heaters was on my radar because Yelp helped me reach out to a few companies based on my project needs a few months back. A few companies responded but Natalia was not only responsive but provided additional help and insight over the phone. So I knew I would give them a shot when the time was right. Fast forward a few months and it was time for me to replace my gas water heater with a hybrid heat pump water heater. Because it wasn't a simple swap, I had a lot of questions (as did they) and we took a couple of weeks to finalize the plan. I had also reached out to a few other vendors as well but most weren't as informative, nor did they have competitive pricing. I appreciate that Natalia's bid was competitive from the start, unlike other places that instantly give you 20% off when you tell them their price is too high, and ultimately have to grind them down to a fair price. The installer, Sammy, was great and took the time to do things right. He was friendly, knowledgeable, and thorough. He took care of the hybrid water heater, expansion tank, as well as the recirculation pump - all things I didn't have before. I would happily go back to using them again if needed, and highly recommend them to others. read more

It is a regret to choose this company to install water heater. They can't figure out how to install the machine and make it work. And they refuse to cancel the order and sent the third helper and finished the job. I paid the helper the extra work for the underground water pipe myself. And the leaking outside is fixed and the drain pipe was installed finally. But last week, it means months later I found venting pipe inside was leaking and it ruined the ceiling. The terrible thing is the machine doesn't work properly now. I called Navien and they claimed the issue is because of the installation problem. Don't recommend them to anyone. It is absolutely unprofessional. read more

We spoke to Natalia, asking for help regarding our water heater. She offered her support and also asked Daniel to troubleshoot the problem. It was a nice gesture to help us without selling a product but plainly to help us. Her professionalism and friendly manner are an A+ in our book- seldom to find nowadays. Thank you so much, Natalia read more

Do not do not call this people. They are a scam. Do not even trust them to come to your house. Natalie the girl talk on the phone like she is on something. She talked so bad about her employee that came to my house to fix a heater and took the part that he didn't really needed. Then she promised three days in the row to bring the part back. Never happened. Then she asked me to pay her so she can bring the part back which pretty match they took it from my home. When I refused to pay her. She send her address to drive to her home to pick a part from my heater. Unprofessional, those reviews they have is a complete lie. read more

They give me a quote online, arrive on time to replace the water heater even late at night. The price is good. Thanks Natalia!

Great and easy to talk to. FYI They did not have masks on upon arrival nor ever, but the area we worked was outdoors ( I did mask!) mostly ask them to have a mask on prior to hiring if that's a concern. The website says they are vaxxed but verify and REQUEST mask if that is important to u to avoid awkwardness . I appreciated their recommendation for tankless vs Waterheater tank and their quick work. They were ( 2 men) here for around 2 hrs and did fantastic job. I recommend them ; they are a family owned business ! Let's support them! The owner was down to earth n so easy to talk to ! read more

On Call Water Heaters - Brand new water installed per code. - Water Heater Installation/Repair Near Me - Glendale, California

My friend has recommended me this company a little while ago, since I had to replace my broken water heater. They came to replace it very quickly and professionally. The owner of this company, Natalia, is a understanding and patient person to talk to. She helped diligently talk about the pricing in a detailed manner, and it came to my surprise how reasonable their pricing are. I have contacted multiple companies in the past, and I will have to say that this company has been the most reliable so far. I am grateful for all the work they have done for me. Overall I definitely recommend!! read more

I couldn't recommend this company enough for your water heater, supply and installation, needs! I'm sure they have an excellent set of crews, but we had the pleasure to work directly with the daughter & father team, Natalia & Rafael. They went above and beyond to help us out to replace our 15-year old water heater and go tankless! They have so much experience that Rafael made its installation a breeze. They were not kidding when they say they're open/ available for 24 hours! Even with the faulty, brand new unit installed (not their fault) on a Saturday afternoon/ evening and Rafael's busy Sunday schedule, they still managed to replace it with another brand new, non-faulty one that day. Talk about great service, they remain very responsive to any post installation inquiries, if you have any. What a great team, a great company at a great price to get things done! Thank you very much OnCall Water Heaters! More power to you! read more

My tenant called on Saturday morning to tell me the water heater wasn't working. I contacted OCWH, they gave me a quote over the phone and came out that afternoon to install a new water heater. They showed up on time, were polite to my tenant and their quote was $450 less than the plumber I had used for that property in the past. Highly recommend these guys. read more

Natalia, was able to call and respond quickly and provide us with a fair quote to my inquiry and had her technician come the same day. They were able to fix the issue on the water heater. I will be sure to use them when it's time to swap out my water heater for a new one. read more

Summary: I'm a satisfied customer because OCWH charged a fair price and did a timely repair; but I had to deduct one star for reasons described in my review. A "flashing code" on our water heater indicated the burner needed to be replaced. I called the dispatcher at On-Call and she was friendly and helpful. A technician was scheduled to come out on Monday between 12 to 4 pm. Unfortunately, he was a NO-SHOW. They explained that the previous job turned into a water heater replacement rather than a repair, so they ran out of time. They rescheduled us for the next morning. I was okay with this because they kept me informed while it was happening. The next morning, Oscar showed up and replaced the burner unit. He did a great job and the water heater is working again. I was happy that nothing else was wrong, which made up for the previous day's disappointment. Oscar was friendly and easy to work with. But I have to subtract one star for two reasons: 1) Communication issues: I explained to the dispatcher several times that the burner needed to be replaced, per the flashing code on my water heater; but when the technician called me, he hadn't heard about this. Oscar scrambled to get the part before he came out. If I hadn't told him beforehand, TWO trips and further delay would have resulted. 2) Billing issues: I received their invoice by email and was going to pay by credit card. But they preferred a check (to avoid the credit card service fee, I assume). So I wrote a check and it was deposited into their account the same day. Now their automated billing system is sending me reminders to pay the invoice even though I already paid. I'm sorry, but billing glitches detract from the overall satisfaction of using any professional service. However, I'm still a satisfied customer overall and would use them again for my rental home in Monterey Park. read more
