"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."

"I recently had a new HVAC system installed by Aireserv, and I couldn't be more pleased with the results. From the beginning, the team was professional, courteous, and informative. They arrived on time and were very thorough in explaining the detailed installation plan, the features of the new system, and how to operate it. The installation went smoothly, and the technicians cleaned the area while working. Once the system was installed, they ran tests to ensure everything was working perfectly and took the time to answer all of my questions. The new HVAC system has been a game-changer in terms of performance. It heats and cools my home more efficiently than my previous unit, and I've noticed a significant improvement in comfort and air quality. The system runs quietly and maintains an even temperature throughout my home. I also appreciate the energy savings I'm already seeing. My energy bills have been noticeably lower, which I can directly attribute to the new system's efficiency. Overall, I'm delighted with the service from Aireserv and the performance of the HVAC system. I highly recommend them to anyone in need of HVAC installation or upgrades. They provided excellent service from start to finish! A BIG THANK YOU TO ALTON THOMPSON AND HIS TEAM FROM AIRESERV."

"Call in the morning, visit that afternoon with quote, installation next day. They didn't have our model in stock, so we got an upgrade to the next larger water heater at no additional cost. Installer was very knowledgable and friendly."

"Both father and son are experienced and knowledgeable. They seem up to date on current codes and products. They were quick to start and finished installing two difficult water heaters in half a day. They had to make some small adjustments because of our old house which were done well"

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"I had a water heater that suddenly went kaput, but the replacement went remarkably easy. The day it happened, Jess Plumbing ascertained what I wanted for a replacement, bought the heater, installed it and it has worked perfectly ever since. I would use Jess again and will recommend him to others."

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.
