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.

Martin was recommended to me by Yelp's request a quote function. He was one of the few plumbers on the recommended who was willing to give me an estimate without having to send someone over first. The price was fair and Martin was responsive in scheduling a time the same day I contacted him. The plumber on Martin's team that I worked with was knowledgable, professional, and worked quickly to replace the fill valve within 30 minutes. We weren't 100% sure if that would fix the problem since this appeared to be a slow leak so they were willing to hold off invoicing me and ordering additional parts just in case the fill valve wasn't the issue. Luckily replacing the fill valve did the trick but I appreciated the gesture anyways. Still waiting to figure out how their payment works since I received an online invoice with an option to pay online. Anyways they did a great job and I would recommend them for toilet repair.

But Martin got in there and sopped up ALL the water and was able to determine that it wasn't the heater but my HVAC. He was an extremely kind and patient gentleman. He made a call and procured the proper service gentleman for me. He stayed with the HVAC guy until the problem was resolved. In addition I realized that I would be actually needing a NEW water heater in a very short time. So I made arrangements with Mr. McManus to have that done. I can't adequately express how impressed I was with both the quality of service and the timeliness of his response. I would bestow my most unabashed praise on Mr. McManus and both his professionalism and attention to both my needs and requirements and what was needed to get the job done. 5 STARS

Great job and extremely professional…read more Bruce and team were a pleasure to work with. They were extremely fair with their prices and went above and beyond to make sure we were happy with the work. My wife and I hired them to do a whole house filtration system for an acquasana filtration system. They had it installed in 2 hrs and inside the estimate they provided. They realized the parts in the kit were crappy, and used their own pipe connectors because they were concerned with durability. They even went so far as to fix our leaky sink just because he noticed it dripping!!. No charge :-).

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!

Overpriced and incompetent…read more This company has worked on my house 5+ times over the last month, amassing to nearly $10k, and each time they come, a new problem arises, each problem costing more. Most recently, they came to repair a leaking pipe, and left the same day after subsequently cutting/breaking multiple pipes in my basement, leaving our entire home without water. They even assured me before leaving that I would at least have cold water, then were surprised when I showed them they left me without any water at all. They came back only with a quote for whole home repiping, and not even a quote for just fixing the local spot of damage. I have now had three separate plumbing companies inspect and evaluate the situation after this, and all of them are in agreement: 1. JN Service made poor technical decisions in trying to fix the pipes, in addition to the state they left the piping, and separately in the way they installed my water heater. 2. It's concerning that JN Service didn't even provide a quote for fixing the local issue, and only provided a quote for a full-home repiping. The interpretations are ranging from bad-practice, to predatory. 3. The whole-repiping quote from JN Services was severely overpriced, and it was additionally concerning given that the initial quote had no information/line items besides just listing the rooms in my house that would be involved in the repiping. It wasn't until I pressed JN Service, that they gave a quote with more extensive information. All in all, I will never work with this company again. I recommend others never work with them. There are other companies that provide better competency at better prices.
