Price was reasonable for the scope and system specs, and James was extremely responsive and patient throughout the whole process. We also really appreciate James's help coordinating with MassSave (including some truly terrible inspections), ultimately enabling us to claim our full rebate. I'd highly recommend working with James, and we will continue to reach out to him for all our HVAC needs!

After a 3-yr search and MANY bids for a new HVAC, we settled on James Wu, who installed our system…read morelast month and proved the research paid off. Below are things I wanted to know before choosing a contractor; maybe it will be helpful for you. Our situation: 100+ yr old home with current boiler in basement. We recently insulated our walk-up attic - that would both freeze and melt items stored there - with closed-cell spray foam (more research there), added drywall and will use it for storage. This is where the air handler and ERV (for ventilation) went. Our upstairs is now ducted, with one vent running through a closet on the 2nd floor to 1st floor. We also added a Mitsibishi floor mount unit and a ceiling cassette on 1st floor. So, we had a VARIETY of equipment installed, requiring a contractor experienced in not only ducting, but mini-split installs with both a ceiling cassette and floor mount unit. We did not want the large wall mount mini split units. Our walls/ceilings are PLASTER, (metal wire mesh and cement-based): cutting them is a JOB. And, we wanted the floor mount unit RECESSED. COST - James was in-line with our other bids, which came in between 27k and 39k, largely depending on equipment recommended, with ceiling cassettes costing more. Many contractors simply would not install them, and wanted to run ducts in the corners of all upstairs rooms to first floor, which to us was a last resort. COMMUNICATION - James is very responsive to texts, emails, and even more importantly, he is a fantastic communicator. He is very calm, not pushy, explains things in an easy-to-understand way that clearly shows he knows his business. I actually told my husband after he left for the first time, "I think we may have found our guy" just based on his personality and knowledge. He's likeable, which isn't a requirement, but definitely helps. EXPERTISE - This is what truly sets James apart. Our needs were fairly complex, requiring interior ducting, 2 outside units with exterior line sets, and recessed ceiling units, but also RECESSING the inside floor unit into an interior wall. We've overseen several renovation projects recently and could tell these guys knew what they were doing. Also, they were perfectionists, and paid attention to details you don't often find with contractors. DEPENDABILITY - Not a single missed appt. Showed up on time with clear communication. The job took a week. He also helped with Masssave paperwork. They cleaned up after themselves each day, which we appreciated. KNOWLEDGE - Extremely versed in Mitsibishi equipment. He's a Diamond Contractor, which extends our warranty, but we'd have chosen him regardless. Every question I had about these units (cassette and floor unit operation, air handler, ERV, outdoor units, thermostats...) he knew the answer to. When I researched anything specific online, from multiple and trusted sources, I found the info he'd given me to be correct. I trust his knowledge and I don't automatically do that. One example: our ceiling cassette has an internal thermostat and it's off by several degrees regularly. I researched it and found we likely need an external thermostat separate from the unit to measure the room's temp. I texted James a photo showing the inaccurate reading and his immediate reply, "you need an external thermostat. I'll install one." That's what I'm talking about. INTEGRITY - Example: After the permit inspector left, James explained his philosophy on inspections. Each city apparently has different requirements. He learned several years ago how strict one particular city was, requiring a blower test to determine air tightness and the passing score was 4% or less. He got 4.1% and city wouldn't pass it. This required a lot more time/energy to go through everything and another test and more $$. So, now James says to his guys, "We install to the strictest inspection every time, regardless of the specific city's requirements, so we don't ever have to redo anything." In our case, the city didn't need a blower test but if they did, I feel confident we would have passed! I don't often take time to write reviews, esp this lengthly, but I felt it was warranted here. Finding an HVAC contractor is HARD; it's time-consuming and complicated. And a lot of money. Three years of research finally led us to James and now, looking back, it was worth the wait and headaches in research. I would highly recommend anyone in the market for a new HVAC, especially if it involves Mitsibishi and especially ESPECIALLY if it involves recessing any equipment like ceiling cassettes or wall units, to consider James Wu. He and his team are uniquely skilled in their work.

Okay. The technician fixed the Goodman system and the AC is working. It is definitely not cheap…read more The total cost before discount (10%) is over $1500. I had to find the discount on their website separately because they do not offer to me automatically. I am not happy with the communication and the thermostat replaced. It is a rental property. Unlike other companies I used, I never received a call 30-60 mins before the technician arrived. So I was not sure if he showed up or not. Whenever I called the company, I was talking to the teams handling customer service, not the technician directly. So there is always a middle man between the tech and me to translate information. The diagnosis was on Wednesday. I approved the quote right away after I received it. The repair was the next Thursday 8 days later. The appointment was initially scheduled for the morning between 9-12. I then got a call to say he could not make it on time and would be there around 1pm. I got a tenant message to say he still did not show up at 2:30PM without any call to inform he would be further late. What I am most disappointed is the new thermostat installed during this repair! He replaced my old programmable thermostat with a new FocusPro N100 Non-Programmable Thermostat 1H/1C. When every household is switching to a smart thermostat, he installed an ancient manual controlled thermostat! I would appreciate he could give me some option to select different types of thermostat. I would have no problem to pay for something better or even buy a smart thermostat myself. I called the company to complain about it. All I got was it is fully functional and it is more modern than my old programmable thermostat! I could not be more disappointed about this. Despite they fixed my AC, I do not feel comfortable to use this company again and to recommend it to anyone else if this is not addressed.

We never authorized it. Now they are alleging that when they swapped the part (which we never authorized to be swapped) it fried and hence we owe it to them.

They've been great.. up until recently, when they started advertising on TV! I'm on Automatic Delivery and I noticed that my Oil Tank Levels have gotten quite low before they've come to fill the tank the last couple of months. This month it's even worse! I called them on Thursday because my tank was showing less than 1/8 Tank. I was worried about running out of oil and my pipes freezing in this extremely cold weather. They assured me I'd have oil delivered by Saturday. It never happened! Currently, my oil tank gauge is reading "Empty"! I called again today, Saturday Afternoon at 3:30 pm. I got the answering service who told me the office was closed but that a service technician would call me back. It is now 7:40 PM and I still haven't heard back from them. A call back would be nice, so that I can get an update and/or if I need to call someone else to deliver fuel! Not knowing is the worst part! My anxiety is Over the Top right now because running out of oil and losing my heat (as well as damage to my heating system) is just hours away because of their INCOMPETENCE! This is totally UNACCEPTABLE & UNNECESSARY!

We've had a very long challenging history with Atlantic. The only reason we keep using them is…read morebecause our contractor really pushes using them, and it's hard to find an alternative in any case - I've had one other service out but they didn't really instill confidence. We moved into our condo 19 years ago; central AC stopped working when the next summer rolled around. Same with the next, and the next - a new coolant refill every time. Eventually, when pressed for an answer, Atlantic reported suspicion of a leak in the system, but were unable to find it over the next 5-ish years when AC kept failing to cool right when it gets really hot here each summer. At some point we decided to purchase a new system that cools the air within the unit - bypassing the concern about a possible leak. Absurdly expensive b/c it's huge and on the roof, requiring a crane etc. Except, that one also fails about every one-two years and no one knows why. They're *very good* at making you feel like this fix is the one that will stick, but it never does. Wish we had pushed for a warranty-based fix before our warranty ran out. Also, lots of variance between technicians. This summer, when the system failed per usual and I had to have a technician out, the first technician exclaimed that the amount of rust in the system was very concerning because we were "breathing it all in." When I showed it to an Atlantic salesperson/technician a week or so later, he said that there was absolutely no health risk and that the rust was completely normal. Which one to believe....? In the meantime our mini-splits on the lower floors have been conking out over the past 2-3 years - all pretty old. Said salesperson/technician from the last visit came to provide an estimate two weeks ago. Despite attempts to reconnect with him, he has vanished. I was hoping to get the AC taken care of by now as we're nearing July and it's going to get extremely hot here, but I'm about done with this company.

It's possible that many of my issues were simply bad luck out of Akian's control; but the number of them still leaves me somewhat skeptical. ----- Got central heat/AC installed a year ago; installation dragged way over the predicted time, but was otherwise fine. Expensive, to be sure, but you expect that in these parts. "Free" annual maintenance time? Four house calls later, still have no AC (I think it worked before being "maintained" but if it had an issue over the winter, I wouldn't know), which I'm now told will be the case for the entirety of May. Communication has been dismal- e.g. getting a text for an upcoming appointment nobody told me was even a thing (apparently the maintenance wasn't completed and nobody told me). Multiple "whoops, we need to order a part, we'll call you in a week or two". Why a part gets ordered on the fourth house call? Beats me. Why they can't stock parts for the products they themselves install? Beats me. And I've paid for a surge protector as part of this "free" process (why wasn't it included initially? Who knows!) If you want to be stuck in a 95-degree house, I recommend Akian. If you want new people coming to your house to chat every week, I recommend Akian. If you want to actually get working HVAC, please let me know who I can talk to. But I guess most of the people I've talked to have been very nice. If they ever manage to get their act together and do their job, I'll update this review.
