"This review is hard because I have previously used this business several times over the past few months. However, I’m so profoundly disappointed in the service I received from Super Service Today last week that I feel compelled to share my experience. Two months ago, I told Super Service Today about a basement leak in the utility room. They charged me $180 diagnostic fee but couldn’t identify the source of the leak. I was assured that things looked as if they were in working order (i.e., water heater, piping, and boiler) and that I would get consideration for the $180 diagnostic fee I paid (without getting a diagnosis) if the leak were to recur. Well, the leak recurred in the basement utility room 2 months later. The "consideration" that I was promised went out of the window once they got their initial payment, and I was charged an additional $5000 for the replacement of a new water heater. To make matters worse, their plumber failed to ensure that the tenant’s hot water and heat were functioning after the water heater installation. The tenant understandably complained, so I reported this to Super Service Today. They inform me that their plumber never switched the valves back on, so they sent the same plumber the next day. Since the door was locked and I out of town, I had to pay $200 for a locksmith to unlock the basement. Super Service Today refused to pay for locksmith despite the fact that the need for the locksmith was a direct result of their mistake: leaving the valves off. After the plumbers comes, he then says that there must be an electrical problem with the relay box because the heat and hot water still won’t turn on. Despite the implausibility that the electrical wiring and/or relay box that were perfectly functioning with the bad water heater would suddenly malfunction with the installation of a new water heater, we have an electrician come over the next day for another $450. The electrician tells us the obvious: there is no electrical problem and all the systems are receiving the appropriate signals, that the boiler is hot, and that the issue is clearly plumbing. Additionally, the senior electrician (who has 20 years of HVAC experience) says that the proximate cause is that the plumber introduced an air bubble into the system during the installation of the water heater. I verbally share the summary of the electrical diagnostic information with Super Service Today at 11:43 am Eastern time on Friday, and finally after a second call, the plumber calls me back at 3pm who says he will share it with the office. I don’t get a call back (this is now the 3rd day for my tenant without heat or hot water), so I call back in 1.5 hours, later only to be told that addressing an air bubble in the boiler is out of scope despite the fact that it was introduced during their $5000 water heater installation. Furthermore, because it is now at the end of the day, they would have to charge me an emergency fee of >$150 (for nights/weekends) + $180/hour to diagnose their own incompetence. I passed, put my tenants in a hotel, and hired a trusted plumber who solved the multiple problems in a couple hours. Yes, that’s right, in addition to introducing an air bubble into my previously functioning system, my plumber documented that they erred in the installation of the water heater. It’s no wonder why there was no heat or hot water. I can deal with infrequent mistakes, as everyone is human. I can't suffer people who make mistakes and don't own them, blame other people (like the electrician), and want to charge you exorbitant amounts to fix their own blunders. That's unacceptable They were paid to leave everything in good and working order. Instead, they left me in a lurch, with large out of pocket costs, and very unhappy."

"I used Sila for the first time this year using their Triple Bundle Coupon (Heating, AC, and Water Heater maintenance). I would highly recommend just calling them to book your appointment (the online chat is not as helpful). But otherwise super easy to book an appointment. They gave me a call about an hour before the tech was supposed to arrive and he arrived within the expected time. I had Nick as a technician. He was extremely cordial and I appreciated how he brought shoe covers (for when he had to walk around inside my home). I also really appreciated all the information he provided after the service was completed. He gave suggestions and product information hat could help improve the performance of my systems and helped explained what those items were in a way that I (not a HVAC pro) can understand. Really glad I used them for my PM this year!"

FAQs for boiler installation projects in Concord, NH
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.
