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.

This place made me wait and then sent the dumbest technician I have ever met. I had to operate his…read moretablet for him and repeatedly point out that the information he was looking for wasn't on the unit's label while he constantly told me he wasn't very familiar with Lennox systems, even though I called them because they are a Lennox dealer. I ended up having to help him through checking everything. I eventually got an "estimate" that included overpriced repairs that cost as much as replacing the unit. It had a digital "signature" on it that just was the tech writing NA. I never actually signed anything. Nothing they sent me mentioned anything about late fees, but considering I was done with this company and couldn't get them on the phone reliably to pay I mailed a check. The check was never cashed, and I tried calling a couple times over the last year. Now almost a year later they email me telling me I have a years' worth of late fees because they never cashed the check. I finally was able to call during the day (not always easy for me). I got a person who again told me the person I needed had already left for the day. I told them if they wanted to be paid they needed to take the card over the phone right now. She agreed. Then told me the current balance. I refused to pay the late fees and told them I would authorize only the original balance. She put me on hold while she checked and then blind transferred me. The person answered like they had no idea who I was. I explained the situation again (very frustrating) and he knew exactly who I was and already had the information. He stated they have several ways to pay, except apparently those ways aren't check since I tried that. And none of the mailed "invoices" I received provide any payment information, terms and conditions, or anything but the current balance and how many days late it was. Just "Past Due - Please Remit" and an address along with a return envelope. But I had already tried that. This person claimed to be willing to take the payment, but when I rejected the late fees he claimed he needed to investigate and would get back to me. I told him I am not available during the day and he scoffed at me. I gave him one final chance to accept the payment without late fees right then or I was going to stop even attempting to pay as my life doesn't revolve around a waste of time diagnostic service with a technician that didn't know what they were doing. It shouldn't be this hard to pay them. The late fees should have never existed if they just cashed the check I sent or had ever provided me with payment instructions. other than "Please Remit", a return envelope, and an address. I will never use these people again. Everything with them is a clown show. Can't get straight answers, can't get things properly diagnosed. Can't get trained people. Can't even pay their bill. AVOID AT ALL COSTS!!!!
