"It went great. Called at 8am and they were at my house by 10:15 am quoted then immediately started the install. They have their own stock of tanks so they bring one with them when they come out."

"Aire Systems of Campbell and Saratoga truly sets the standard for exceptional service in the HVAC industry. Alton, the owner, went above and beyond to ensure I understood every aspect of the process, from selecting the right system for my small home to navigating available rebate programs. His expertise and dedication to customer satisfaction stood out as he guided me through the rebates step by step, emphasizing how beneficial they are despite the effort required. What really impressed me was Alton’s commitment to follow through—he’s not just selling systems, he’s supporting his customers well beyond installation. Daniel, the team lead installer, was equally remarkable. Always punctual and professional, he demonstrated a level of care that extended beyond the job itself. He kept me informed daily, explaining what was being done, what to expect next, and how long it would take. Knowing I had to leave for work, Daniel kindly spent time with my dogs, making sure they felt at ease while he worked. It’s rare to find a company that combines technical expertise with such personal care. Aire Systems, with Alton and Daniel at the helm, earns my highest recommendation!"

"It went incredibly! Gustavo did a wonderful job installing a brand new stainless steel sink, and it looks like it has been there since the kitchen was first built! Seamlessly ties in all of our appliances, and he stayed a little later to get to project done in one day! Gustavo came out and did an original consult before we hired him, and he was super friendly! I will be hiring him for all of my plumbing needs going forward! His work is quality, and he is a quality human being! He made me feel totally confident in the estimate he gave me, and the result is better than I could have imagined! Thank you Gustavo!"

"I can't recommend Water Heater Boys highly enough. They replaced our gas water heater, which sits in a tight lower-level closet, and from start to finish the whole experience was excellent. The team clearly knew exactly what they were doing and they handled the awkward placement without any fuss and made what could have been a stressful job feel completely routine. A special thank you to Jaya, Tyrone, and Raul on site who were efficient, careful, and didn't cut a single corner. And to Leonardo, who coordinated everything: that was hands down the best customer service I have ever experienced with a contractor. The pricing was genuinely great too, with an upfront quote and no surprises along the way even when the work must have been way harder than expected. These guys worked their butts off. They left the space clean and made sure everything was running perfectly before they wrapped up. Competent, honest, and hard-working; truly more than I could have asked for. After this experience,"

"We really appreciated that they accommodated a quote and installation on the same day for two new toilets. No issues found and they had a friendly demeanor (both the coordinator and plumber that installed)."

"The entire project from start to finish was fantastic. Within minutes of requesting a quote I received a text with a time they could be at the house. Rodney called to ask some questions, gave me an estimated price and time. Rodney was great to talk to and was very knowledgeable and helpful. Rolando arrived a little early which was great. He figured out what needed to be done and gave me an estimate which was within the range mentioned and started working. It took an hour to complete. Rolando went over what was done and why. I was extremely impressed with Rolando, he was courteous, informative and did a great job installing the water heater and bringing everything up to code. I wouldn’t hesitate to call Better Water Heaters again."

"When a pipe burst in our garage, we were pretty stressed trying to figure out what to do. Ron came out right away, shut everything off, and replaced the section of pipe that broke. He worked quickly but also took the time to explain what had happened and how to avoid it in the future. Really grateful for how calm and professional he was in a stressful situation."

"Dave and Eric did a good job with a challenging dryer installation. They arrived on time and were very careful of my hardwood floors. Dave also replaced the spout in the upstairs bathtub.
I was very happy with the results. I have used Tool Time in the past and have always been pleased.
However, dealing with the bill has been problematic. Usually Eric, the owner, would come by, inspect the job, and I would pay him. Dave/Eric didn't know about the payment procedure, called the office and was told someone would call me.
I was never called, tried calling, left a voicemail, then sent an e-mail, no response.
After 3 weeks I sent a check for what I thought was the correct amount to the Constitution Ave  address. No acknowledgement, no receipt. Last week I received an e-mail invoice for $200; I again tried to call -voicemail was full, sent an e-mail, again no response.
If this business is trying to expand, this is not the way to do it. If I use them in the future, I would need to know the payment procedure and that I would receive a receipt.

"I met with Ethan in December of 2020 and we signed the contract, after I spoke to a few other contractors because he definitely had the best pricing and really good reviews. The work only started 6 months after the contract and in the meantime the raw material cost went up but Eitan did not increase the price of the contract despite including all raw materials in the contract. He uncovered a problem in plumbing while installing brand new windows, despite that there was only two week delay in the schedule. He built me my dream kitchen and all along the way advised on what would actually look nice because I did not hire an interior designer and I was doing it on my own. Build the Bay is trustworthy, clean (which was super important to us because we were living in the house through the construction) and proactive. I would totally hire them for another construction project if something should come up in the future."

"Wilmar Plumbing was very responsive and empathetic towards my situation. They had to fix a problem caused by the previous plumber who installed my shower/tub drain incorrectly. I couldn't shower due to the leak. They treated my case like the emergency it was and Wilmar and his team showed up first thing. They fixed it diligently. They were so good, I hired them to install new bathroom sinks. These guys are great!"

FAQs for boiler installation projects in Cupertino, CA

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

It usually takes a professional water heater installer between two and three hours to remove an existing water heater and install a new tank heater. However, it could take four to five hours if they have to work in a small utility closet or another tight area, like a crawl space. Tankless water heaters have a more complicated installation process, so they will take a bit longer. Additionally, a gas water heater requires a connection to a gas line, and that alone can add about an hour to the installation timeline compared to installing an electric water heater.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350
