"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!"

"Our water heater started leaking and needed to be replaced. Called in the morning and had someone out in the afternoon. This was actually our second quote. The first guy only gave the heater a cursory look before quoting a price. The Better Water Heaters technician actually examined the heater, plumbing and electrical connections before discussing options. We discussed replacing the original and switching to a tankless system. After we did some research and asked some friends who had a tankless system, we decided to go with the tankless. We scheduled an appointment for the next day and had it installed. Very smooth, very professional."

"Eitan and his crew at Build the Bay came highly recommended to me by my sister-in-law and her husband who used them to remodel their bathroom. Working with Eitan was a delight! He responds within minutes of text messages and phone calls. He is very reliable and a man of his word. The crew at Build the Bay remodeled our bathrooms and we couldn't be happier. The crew takes pride in their work and it shows in the final result. If something was amiss, I merely had to speak with either Eitan or Jesus and the problem would be addressed immediately. His crew was also great to work with and very accommodating. It is not often you find a contractor who is so focused on both customer service and quality of work. We were so happy with their work, we will be starting another project with them next month. I highly recommend them!"

FAQs for boiler installation projects in Fremont, 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
