How do I know whether my water heater needs repair or a complete replacement?

If your water heater is under 8 to 10 years old and experiencing isolated component failures such as a faulty thermostat, worn heating element, or dripping pressure relief valve, a professional repair is typically the most cost-effective solution. However, if your system is over 10 to 12 years old, exhibits signs of internal tank corrosion like discolored rusty water, or has an active leak at the base of the tank, a complete replacement is required to prevent water damage and restore efficiency.

What are the main differences between a traditional tank and a tankless water heater?

Traditional storage tank water heaters maintain a reservoir of 40 to 80 gallons of hot water continuously, offering a lower initial purchase and installation cost. Tankless water heaters heat water on demand as it flows through the unit, providing virtually endless hot water, occupying up to 80% less space with wall-mounted designs, and lasting up to 20 years or more with significantly higher energy efficiency.

Why is my water heater making loud rumbling or popping sounds?

Loud popping, knocking, or rumbling noises are typically caused by sediment buildup at the bottom of the tank. In Greater Boston, hard water minerals like calcium and magnesium settle and form a dense layer over time. As the burner heats the water, trapped steam bubbles burst through the mineral crust, causing popping sounds. An annual professional tank flush can clear this sediment and protect the tank bottom from overheating and premature failure.

How long does a professional water heater replacement take?

A standard like-for-like replacement of a traditional storage tank water heater typically takes between 2 to 4 hours. Converting from a traditional tank to a high-efficiency tankless water heater or hybrid heat pump system generally requires 4 to 8 hours due to the installation of dedicated venting, upgraded gas lines or electrical circuits, and customized piping configurations.

Are permits and licensed plumbing inspections required in Massachusetts?

Yes. Under Massachusetts State Plumbing Code (248 CMR), all water heater installations, replacements, and major gas or water line modifications must be performed by a licensed Massachusetts plumber who pulls the required municipal plumbing permit and schedules the mandatory local town inspection.

Can I qualify for Mass Save rebates when installing a new water heater?

Yes. Homeowners in Massachusetts who install qualifying high-efficiency electric hybrid heat pump water heaters or high-efficiency condensing gas water heaters may be eligible for significant utility rebates and incentives through the Mass Save program. Akian assists homeowners in selecting qualifying equipment and navigating documentation.

  Very happy with the service. The plumber arrived on time, explained everything that would be done and approximately how long it would take. He was very courteous and put a tarp down  and wore shoe coverings while working. I will definitely use this company again.

  Update to the update. I am sticking with Akian. They are a big company with many competent technicians. They respond timely. They do their best to make customers happy. It's hard to know when things fail where the fault falls. But they have been responsive and they have fixed issues with little to no charge as appropriate. See below for history.

----
Update to my original review. Some years later, after having them install new heater, water heater, and AC.

The heater that akian has since installed 3 years ago has run into problems every year since. One time, one of the vent pipes was not attached properly. It was under 1year since the installation so they fixed it for free. Nex time, it was an issue with exhaust piping. Must have been some other installation errors but since it had been more than a year since installation; we were charged for the repair. And now again, we have cold air blowing from the system and I am calling them.

Side story. For the exhaust issue, the first technician they sent misidentified the problem claiming it was because our vents were not fully open. Then Manny, the technician who I praised in my original review was sent; he identified and corrected the problem. So turns out not everyone in their employ is the same.

-------
I call about a heating system emergency; our furnace is broken on a cold week. Their earliest availability is in four days. But since it is an emergency, they make some calls, and send over someone immediately. In this day and age, when HVAC companies rarely respond or show up.

Manny comes over, identifies the problem, and fixes it. All along, he is honest about what he may or may not be able to do. We are lucky, the current problem was solvable. But he points out that the heater is old. He lays out options for the future; we may replace the flame sensor that caused the current problem if the same issue arises; we should consider a complete system replacements; and he has identified a list of worn out parts if we want to try to extend life of existing system. No pushiness, no BS, just reasonable opinions.

I can't know if all their technicians are as knowledgable and capable as Manny. But next time we have HVAC needs, we are calling Akian again.

  I DO NOT RECOMMEND THIS COMPANY AT ALL!

The company quoted me a $129 diagnostic fee. However, when the technician arrived, he barely did anything other than take a quick look at the equipment. He then told me that the $129 only covered his less-than-30-minute inspection, and that if I wanted any further service, I would have to pay an additional $249.

This was completely different from the information I received when I initially contacted the company. To make matters worse, the technician refused to provide me with a quote. I explained that I did not want to be nickel-and-dimed with one charge after another, but he showed absolutely no understanding.

His attitude was extremely unprofessional. He acted as though he would refuse to do anything at all unless I agreed to pay the additional $249.

In the end, I decided to pay the $129 just to get him to leave. This was an incredibly frustrating experience, and I felt pressured into paying for virtually nothing.

Save yourself the time, money, and frustration. I strongly recommend avoiding this company’s services!

  Disappointing Experience – Unexpected Fees and Poor Communication

I scheduled an HVAC diagnostic appointment with Akian after being told by their office that the diagnostic fee would be waived if I decided to proceed with the recommended repair after receiving an estimate.

However, when the technician arrived, I was told a significantly higher diagnostic fee would apply, that it would not be waived even if I proceeded with the repair, and that I would not receive a repair estimate unless I agreed to pay the higher fee. This was completely different from what had been communicated when I scheduled the appointment.

My main frustration is the lack of communication and transparency between the office and the technician. I specifically confirmed the pricing and process before booking so I could make an informed decision about whether to proceed with repairs. Instead, I was put in an uncomfortable position during the appointment.

  We recently had our hot water heater replaced after our previous heater failed and flooded our basement. We couldn't be happier with the entire experience! From start to finish, the process was smooth, efficient, and professional. Manny and his team arrived right on time, carefully removed the old unit, and installed the new heater with expert precision. Manny had made our job a priority.

The new hot water heater works flawlessly, providing consistent, hot water with impressive energy efficiency. Manny was friendly, knowledgeable, and took the time to explain how to maintain the system and the automatic water shutoff.

Overall, this replacement has brought us peace of mind knowing we have a reliable source of hot water for our home. We highly recommend this service to anyone in need of a quality water heater upgrade! Akian had also replaced our gas furnace at the end of 2024 and had the same excellent service.

  Matt B. is exceptional and has an encyclopedic knowledge of boiler systems. He can answer questions about every permutation of considerations in the lead up to purchasing an efficient, safe new boiler. We were pleasantly surprised by his fluency and responsiveness when we peppered him with over an hour of questions and the company’s patience with us in considering a major purchase. I would highly recommend Matt and Akian Plumbing.

 Verified Absolutely horrible.
Repeatedly reschedules due to their own errors and takes multiple trips to fix an issue to drive up their hours.
Customer service is terrible and unresponsive after 4:30 and they offer no weekend support. 
We have been without hot water for over two weeks because of the company but charged over $1000+.

 Verified I called to ask for a general price range for replacing a P-trap. They told me they would not provide any pricing information unless they first sent a master plumber out for a $120 service call.

I even asked what the *lowest* possible cost for a basic P-trap replacement would be, just so I could have some idea of what to expect, and they still refused to answer.

That made me uncomfortable. I understand that an exact quote may require seeing the job in person, but refusing to provide even a starting price or rough range felt unnecessarily vague. I didn't feel comfortable paying $120 upfront without having any idea what I might ultimately be charged, so I decided not to move forward with them.

 Verified Sean and Andrew were great. I came home from work one day to discover water damage to my bathroom ceiling. Sean came out quickly to assess the situation. He was able to get someone out to remediate right away. Once the cleanup was complete, Andrew came out to do some further investigate and was able to successfully identify the water source in my very old condo building in Brighton. Both were very friendly and professional. Highly recommended!

 Verified So wanted to give an update to a 2 star review i left for Akian for work done about a month ago.  I had two gripes:  Call center customer service and dispatch and high pricing.
I have to give their management credit:  They saw my review, reached out and yesterday service manage Jeff called me.  It's rare these days for someone to really listen to how things looked on my side of the road and to Jeff's credit he did that.  Not only that we reached and agreement regarding what i felt was high pricing two two of the three components they replaced on my AC system.
In addition he mentioned that they are moving away from the foreign call center customer service--this is a good thing.  Who wants to feel if they get disconnected they can't call the person back?  All this reassured me that despite some issues they are getting themselves on track and that they cared enough to make things right for me.

 Verified Carlos came today to troubleshoot my central AC. which stopped working yesterday.  He was very upfront saying that he was unfamiliar with my particular set up. However, with assistance from his office, he was able to diagnose and fix the issue.  It was not a simple 1-2-3 due to the poor initial installation from another company 9 years ago.  He was diligent looking for solutions and was able to get the  AC working.  Part of the issue was the thermostat, which he replaced.  I will make Akian my go-to company for my system. thank you Carlos.  It is only a 4 because I was hoping for same day services yesterday.

 Verified Do not call if you actually have an emergency.  Called them around 5pm this afternoon, told them my toilet was leaking all over the floor and that I was on the ground floor of a multi-floor condominium building.  They opened a ticket and said someone would be out between 6pm and midnight.  Called around 6:30 to see if there was an update, because even with the water turned off I had about 2 inches of water leaking out onto the floor.  She said the plumber was finishing up a call then heading to me.  I called an hour later and she said "oh, we don't service multi-floor buildings you will have to call someone else but they NEVER called to tell me.  Wasted two hours waiting for a plumber that was never coming, causing damage to the bathroom floor and the carpeting in the hallway.

Warning Signs Your Water Heater Needs Repair or Replacement

Water heaters in Greater Boston operate under demanding conditions due to regional seasonal temperature swings and local municipal water mineral content. Recognizing early warning signs allows homeowners to address mechanical wear before experiencing disruptive leaks or property flooding:

Water Pooling or Tank Moisture: Moisture or standing water around the base of the tank indicates an active leak, failing drain valve, or a fractured inner vessel that requires urgent attention.
Loud Popping or Rumbling Noises: Heavy mineral sediment traps boiling steam beneath a dense crust at the tank floor, creating distinct crackling or banging sounds during heating cycles.
Rusty, Metallic, or Discolored Water: Discolored hot water suggests the sacrificial anode rod has expired and the steel tank walls are actively rusting from the inside out.
Lukewarm Water or Rapid Temperature Loss: If showers turn cold prematurely, failing heating elements, broken dip tubes, or burner malfunctions are often the underlying cause.
Equipment Age Exceeding 10 to 12 Years: Standard storage tanks have an average useful lifespan of 8 to 12 years. Proactive replacement prevents catastrophic failures and emergency disruptions.

Key Factors When Selecting Your New Water Heater

Choosing the right replacement system requires evaluating household capacity, fuel supply, and long-term operating efficiency. Our certified technicians perform detailed sizing assessments before recommending an optimal solution:

Household Sizing & Peak Hour Demand: For storage tank systems, first-hour rating (FHR) in gallons ensures adequate capacity. For tankless systems, flow rate measured in gallons per minute (GPM) determines simultaneous fixture capacity.
Fuel Source & Mechanical Venting: Natural gas, electric, or hybrid heat pump options require dedicated venting channels and adequate supply piping in compliance with the Massachusetts Uniform State Plumbing Code (248 CMR).
Energy Efficiency & Mass Save Rebates: Modern high-efficiency systems lower monthly utility bills significantly. Qualifying heat pump and gas condensing models may also be eligible for substantial cash rebates through the Mass Save energy efficiency program.

Navigating Traditional vs. Tankless Technology

One of the most frequent questions we receive involves the choice between traditional storage tanks and tankless (on-demand) water heaters. Traditional tanks are reliable and offer a lower initial installation cost, making them a staple for many homes. However, tankless systems provide an endless supply of hot water and occupy significantly less space, which is a major advantage for smaller utility rooms or large families with high demand.

Our technicians can walk you through the pros and cons of each technology, including the venting requirements and gas line sizing necessary for a successful tankless conversion. We aim to provide you with the information you need to make an informed decision that fits your budget and lifestyle.

Key Features of Our High-Efficiency Water Heating Units

The only downside is that you may never want to get out of the shower! Our team can walk you through all of your water heater options and help you determine the right choice for your needs and budget. Many water heaters even offer warranties, and we can help you through that process as well.

Why Trust Akian Plumbing, Heating, Cooling & Electric?

We believe in a “safety first” approach. Water heaters involve high pressures, high temperatures, and either high-voltage electricity or combustible gas. Attempting a DIY repair or installation can be dangerous and may lead to code violations. Our plumbers are fully licensed and stay updated on the latest Massachusetts plumbing and fuel gas codes.

When we enter your home, we treat it with the utmost respect. We use drop cloths, wear shoe covers, and ensure that the work area is left as clean as we found it. We also handle the disposal of your old, heavy unit, taking that burden off your shoulders.

Frequently Asked Questions

How do I know if I need water heater repair or a full replacement?

If your water heater is under 10 years old and experiencing minor issues like a faulty heating element or a leaky valve, repair is often the best choice. However, if the tank is over 12 years old, showing signs of internal corrosion (rusty water), or has a major tank fracture, a professional water heater installation is more cost-effective in the long run.

What are the benefits of switching to a tankless water heater?

Tankless water heaters provide an endless supply of on-demand hot water, take up significantly less space, and are highly energy-efficient since they don't maintain a standby tank of hot water. Our new units also feature advanced freeze protection and stainless steel heat exchangers for maximum durability in the Massachusetts climate.

Why is my water heater making popping or rumbling noises?

Rumbling or popping sounds are typically caused by sediment buildup at the bottom of the tank. As the water underneath the sediment boils, it creates steam bubbles that "pop" through the debris. Professional flushing and maintenance can clear this buildup, improving efficiency and preventing premature tank failure.

Can you install WiFi-ready water heaters with freeze protection?

Yes. We install modern high-efficiency water heaters that are WiFi-ready for smart home integration. These units also come equipped with specialized freeze protection designed to withstand temperatures as low as -22°F, ensuring your hot water supply remains safe during harsh New England winters.

What causes discolored or "rusty" hot water in my home?

Discolored hot water is usually a sign that the sacrificial anode rod has been depleted and the interior of your water heater tank is beginning to rust. If caught early, replacing the anode rod can save the unit; if the rust persists, it may indicate a failing tank that requires immediate professional replacement.
