Q:
Is a permit required to replace an electric water heater in Sunnyvale that is same size as previous one? I read that only gas water heaters or major modifications requires permit in CA?
A:
Yes but optional. We never pressure anybody into pulling permits. We just offer them for an additional price. The reason why we don’t pull permits. Some of the times is because the owners themselves do not want the inspector at their home.
Joseph C., Business OwnerQ:
How much would a natural gas tankless water heater installation cost?? I already have the water heater and an old 2011 gas water heater is currently installed.
A:
1500$. Cash only. Depends on what your looking for. Permits are more as well only if you want one

I am extremely happy with Efficient Water Heater service.
I recently replaced my water heater and I am impressed with their high-quality craftsmanship.
They also provided suggestions on both tank & tankless systems and explained me the differences, which helped in making the right choice. Kudos!Helpful 0Thanks 0Love this 0Oh no 0 - Pauline C.San Jose, CA1152May 20, 2024
Joseph from Efficient Water Heaters came to our rescue on Sunday afternoon. We contacted him on Sat evening and he was quick in responding to us.
He came by, quickly figured out the problem and fixed it and took the time to explain it to us. And we have hot water!
He explained that our tankless heater needed maintenance (which we've never done before). So we made an appointment for him to come by again. He even gave us a cost estimate for the service. We really appreciate itHelpful 1Thanks 0Love this 0Oh no 0 - Tony H.San Jose, CA515934Feb 20, 2024
Fair pricing and professional installation. A little hiccup in the initial scheduling but all worked out. Replaced my 15 year-old GE unit that failed with a new Bradford White 40 gal unit. Happy with results.
General advice, do independent research first. Know and insist on make/model you want, and the price you want to pay, then call these guys for a hassle free professional installation and enjoy your hot water.Helpful 1Thanks 0Love this 0Oh no 1Business owner information

We appreciate the time you took to get us some feedback on your water heater installation! Feel free to reach out to us again if you ever need any plumbing/water heater needs.

I want to give a 10 star review if I could. Joseph showed up bright and early for my emergency and fixed my water heater from pushing out water through the pressure valve.
My dumb a** paid him via Venmo when he told me he accepted Zelle. It was over $1k worth of cash. He could've kept it and not return it, but he was honest and paid it right back. Great and Honest!Helpful 0Thanks 0Love this 0Oh no 0Business owner information

I appreciate your feedback and don’t forget there’s a warranty on the work we did. I’ll leave and apply a portion of what you charged on the water heater repair towards a new one when ready.

The owner tried to pretend he did work that he didn't do then when called out on it got really aggressive and started harassing us. He then got his office manager to harass us as well along with many threats when we were just trying to figure out what work was actually done.
He also told us between 8-9am and then tried to gaslight us into thinking we were the ones who got the time wrong despite having text message history on the issue.
When they were harassing us I told the office manager she could talk to me respectfully or not at all and this grown woman decided she couldn't be civilized about it.Helpful 1Thanks 1Love this 0Oh no 1Business owner information

I arrived myself on a job on July 7. Completed a repair and was asked to call the customer 15 minutes before I was done to a brother. Michael, I text you 15 min before I was done and I told you just to Zell us the payment. My office manager called you for payment but you wanted to go on about a make belief story between you and your sister which your sister is the owner and we’ve never dealt with you before.this is all bait and switch. I’m pretty positive and know for sure. I’m a local that’s what you both do. Good luck and we won’t be doing more work moving further.
Oct 3, 2022Previous reviewThis is the second time I've used them and they have amazing service for reasonable prices! I texted them in the afternoon on a Sunday and in less than 24h the issue was fully fixed!
My water heater was still under a parts warranty, but the parts wouldn't arrive for a couple days. Joseph told me he had the parts in stock today and I could pay for them now and get them fully refunded when my parts shipped to him. This part swap let me get the issue fixed ~3 days sooner with no extra cost! - Bharath R.Mountain View, CA04Aug 14, 2024
I needed to replace my water heater urgently. Joseph immediately responded with a quote and worked with me on the pricing to install a new water heater. Ray and Joseph came early morning on Sunday and finished the work in less than 2 hours. Overall, very satisfied with their service.

I got a very quick response when I submitted my initial request for a quote. They were very responsive to all my questions. Joseph and Ray came out on time, explained what they were going to do and did exactly that. They worked hard on a very hot day and got the job done as efficiently as they could. It was expensive but I think probably reasonable. I would definitely recommend this company for tankless water heater installation.

Water heater started making funny sounds, we first heard it at 6pm in the evening and by 9pm that same evening the new water heater was up and running. Yep - Joseph and Ray are that fast and efficient.
