"Perfectly! Bill and his associate arrived when they said they would, diagnosed the problem, left to pick up the required part, and returned with the part and installed it, all without a hitch. I particularly liked the way Bill checked to be sure all the functions of the furnace and air conditioner were working before he finished. This is a top-notch service company!"

"Installation was smoooth, it was done within a day. There was high pressure sales involed which I succumbed into as the sales guys were saying that I had fiber damage in my ducting and since I have kids in the house they said that it was very crucial that I do the change now. It was my fault to not do any more pricing research hence I was a bit gouged."

"I Called to get an in person quote for a tankless water heater flush and left this job with a whole house filter and a fridge connection. When Michael first arrived we inspected the tankless unit and tested the water to conclude flushing was not my best option. He then walked me through my options for home filters and we decided on a Halo system. Michael was very well educated on the subject and gave me the best value filter for my needs. He installed the unit the next day in less than a few hours and left me with a flawless work of art. I couldn't be more impressed with the professionalism he brings to this trade! I also requested to hook up a fridge and he did that in what seemed like 30 minutes. He will be the only plumber I call from now on!! Thank you Michael!!!"

"They came out on time and did the inspection. It was determined that the thermostat was broken. We were shown options that he could install right then and there, and told how we could do it ourselves if we wanted a different thermostat. We chose a different one and installed it according to their directions. We have been toasty warm all winter."

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.
