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.

I rarely leave google reviews. However, I felt like my experience with Aikian was so positive that I wanted to share. I appreciated the professional communication - very streamlined and attentive, the workmanship was excellent. They did exactly what they said they would do. The cost DIDN'T change, after the contract/quote. They were respectful in the home - kept things clean, used lots of drop clothes/shoe protection. There was an aspect of professionalism, promptness, and communication that I so very much appreciated. Would highly recommend. Would use again.

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+.

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.

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!

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.

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.

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.

Common Signs You Need Urgent AC Repair in Middlesex County

It is easy to ignore a small noise or a slightly higher energy bill, but catching a problem early can save you from a costly Air Conditioning Installation down the road. Most systems don’t fail overnight; they give off warning signs that indicate internal components are struggling.

If you notice any of the following, it’s time to call in the professionals:

If your vents are blowing room-temperature air despite the thermostat being set to “cool,” you likely have a failing Air Conditioning Condenser or a refrigerant leak.

Grinding, squealing, or banging sounds usually point to mechanical issues within the motor or the fan assembly.

A functional AC should act as a dehumidifier. If your home feels “sticky” or “heavy,” your system’s moisture removal process has failed, often due to a clogged Condensate Drain.

Expert Troubleshooting for High-Efficiency Systems in Suffolk County

Modern HVAC technology is more advanced than ever, utilizing inverter technology and variable-speed technology to keep your home comfortable while using minimal energy. While these systems are incredibly efficient, they require specialized knowledge to repair. Our team is trained to work on a wide array of equipment, from traditional Central Air Conditioning to high-tech Heat Pumps and Ductless Mini-Splits.

We don’t just treat the symptoms; we find the root cause. If your Smart Thermostat is showing an error code or your system isn’t responding to temperature changes, we perform a comprehensive diagnostic check of all electrical connections and sensors. By ensuring every component—from the outdoor unit to the indoor coil—is calibrated correctly, we help you avoid the “Band-Aid” repair cycle and lower your monthly utility costs.

Why Professional Service Matters for AC Repair in Waltham, MA

Many homeowners are tempted to try DIY fixes, but AC repair involving refrigerants and high-voltage electrical components should always be handled by a licensed professional. Improper handling of an Air Conditioning Condenser can void your manufacturer’s warranty and lead to safety hazards.

At Akian, we handle every technical detail, including:

  • Refrigerant Level Checks: We ensure your system has the precise amount of coolant needed for optimal heat transfer.
  • Coil Cleaning: We clear dust and debris from the Evaporator Coil to prevent the system from “freezing up.”
  • Electrical Inspections: We check capacitors, contactors, and wiring to prevent sudden electrical failures.
  • Drainage Maintenance: We clear the Condensate Drain lines to prevent water damage and mold growth inside your home.

Frequently Asked Questions

How quickly can I get AC repair in Waltham, MA during a heatwave?

We prioritize emergency AC repair in Waltham and the Greater Massachusetts Area to restore your comfort as quickly as possible. Our technicians are local to Middlesex County, allowing for fast response times when your Air Conditioning Condenser or Heat Pump fails during peak summer temperatures. We offer night and weekend availability to ensure your family stays cool.

Why is my AC system running but not cooling my home?

If your system is running without cooling, it typically indicates a frozen Evaporator Coil, a refrigerant leak, or a clogged Condensate Drain. For homeowners in Suffolk County, this often results in high humidity and "sticky" indoor air. Our diagnostic process checks all critical hardware, from the Smart Thermostat communication to the Indoor Air Handler, to find the root cause and prevent a total breakdown.

Can you repair high-efficiency Heat Pumps and Ductless Mini-Splits?

Yes, we specialize in repairing advanced HVAC systems that utilize inverter and variable-speed technology. Whether you have a Zoned Efficiency system or a traditional Central Air unit, our technicians have the technical mastery to service complex components like multi-stage compressors and electronic expansion valves across the Waltham area.

What are the common causes of a leaking air conditioner?

The most common cause of water leaks is a blocked Condensate Drain line, which can cause water to back up and damage your home. In older Waltham properties, a frozen Evaporator Coil can also lead to significant leaking as it thaws. We provide professional flushing of drain lines and inspect your system's moisture removal process to ensure your home stays dry and mold-free.

Is it worth repairing an AC unit that uses R-22 refrigerant?

While we can perform minor repairs, the "R-22 Factor" makes major fixes very expensive due to federal phase-outs. If your Air Conditioning Condenser requires a significant recharge or a new compressor, we often recommend a new Air Conditioning Installation. A modern system will be more reliable, energy-efficient, and likely qualify for significant rebates in the Greater Boston Massachusetts Area.
