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.

We called 4 other plumbers and either they couldn't do it, didn't work Sundays, or just didn't respond at all. We found Dalelis on a finding service and saw they were close by, so we called and James picked up and said he could be there in about half an hour. James does what he says he will do. He came in when he said he would and had the problem fixed in about 15 minutes. While he was working, he'd noticed our heating system was ancient and offered to look at it. He told us the one he would recommend and why, and gave us a quote right then on a high efficiency replacement. We'd had several quotes on the job and we knew James' price was very good, and it didn't change after he quoted it. We scheduled the job and we're still admiring the work he and his crew did. The replacement was a work of art, done on time and has been running perfectly ever since. (All the copper was polished ).

He was…read moreextremely professional and transparent, and went so far to suggest that he come back out to give the job a second look after I dragged my feet between getting the original quote in January and choosing to go ahead with the work in late June. I was extremely impressed with the quick work that they did, and how far above and beyond they went to keep the house clean (knowing a lot of the work was going to need the attic access in a baby's room.) Through our project, John discovered a potentially serious electrical wiring issue with our home that he (and Andy, the electrician that he uses) handled perfectly and in a timely fashion. I had no doubts that this minor additional work that came up through this project was in the interest of having done for safety reasons as he was able to explain it to a layman in a way that I could understand. John wanted to walk through the job at the end of the project, show me the work that was done, and confirm that I was pleased with the results. I'll definitely be recommending Seasonal Air to any friends in the area who need HVAC work.

My air conditioning broke during this latest heat wave. I called Several places and Seasonal Air…read morewas very responsive -they came right away. Unfortunately a less experienced technician was sent to evaluate the situation. Seasonal Air was nice not to charge me for their visit, and told me that I needed an electrician to resolve my issue. After spending $300 on an electrician, they diagnosed the issue correctly and told me I needed to bring back the HVAC specialist. When I called Seasonal Air back to request they return to fix the problem, they never called me back. They just completely disappeared. I called 3x, begging them to return my call given it was 95 degrees and very hot in my house. Ultimately I called a different HVAC specialist who was able to fix the problem in an hour -it was a clogged drain-and who was surprised that Seasonal Air didn't recognize the issue immediately as this is a common problem. So I ended up spending $550 to cover the electrician and the HVAC specialist (instead if just paying $250) and lost 2 days in my office (vs one day), and lost 2 nights of sleep (vs one) due to the heat. I hope the Seasonal Air team reads this and reevaluates how they treat their customers going forward.
