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.

They installed central air unit four years ago that is no longer "working" above 84 degrees really…read more On less-warm days it works just fine. The condenscer sounds like it's struggling and there's water on the floor. They sent a techinician on a day that was less-warm and he said "there is nothing wrong with it". (then he told me it's like bringing your car to the mechanic when it's not doing 'the thing"...Ummh by 'the thing' do you mean actually driving because this is not cooling on really hot days and the condenser sounds like it's dying but I get it, it's not doing it now.) He suggested the A/C works better when it's maintained at a constant temperature. I'll change the thermostat setting, and all is great. I paid the service fee begrudgingly because I thought this could've been don'e over the phone, but also Great! Nothing is wrong necessarily, It's not going to explode. Then it was a very-warm day (90's) and the A/C was not getting below 78 degrees inside and the A/C is choking for life to try to keep up. I called the sevice phone person and she said she could send someone in a couple days. I emphatically confirmed that I needed to know what time the day before so I could arrange my work schedule the following day to be there to receive service. *I never got a call from them to confirm that they were coming!!!* which was totally fine because 'it wasn't 'doing the thing' and I had too busy of a day. I just happened to RUN home on a work break to walk the dog and The Koolaire technician pulls up. I apologized but said I was not told he was coming and I would've cancelled if I knew he was coming. I was not expecting him. I never got a call that he was coming, and I would've cancelled if I'd known because it wasn't 'doing the thing' ... super- Warm days again, I call the "service person" and said 'hi, it's me, what am i suppose to do, I want this problem solved, if it's not working when it's really hot out" Kool-Aire returned my message only to inform me that I "turned away a service call" and they were no longer providing me service. I do not like to waste anyone's time, nor others waste mine. Who sends a service tech out and doesn't schedule or confirm a time? She had said to me , 'the phone goes both ways, I could've cancelled'. I have enough calls to make without cancelling an appointment that was never made. She said she was going to call me to confirm an appointment time. She never did. Their refusal to provide service, to hold themselves accountable to communicate properly, to offer any avenue to actually provide "Cool Air". PLease, go elsewhere. You don't need the abuse. They need to hire a new service rep because my need to have a working A/C should align with their need to provide me with a 'working A/C'. That is win/win.

Upon arrival the tech called me and said my systems were so old they would not touch them. They said two were not working (which was a lie) and that I should replace all 3. They made a point to stress safety as their top concern and also said I would never be able to find parts. They quickly gave me a proposal and stressed that they needed to know right away to make it happen for the following week. All this despite having never even looked at my systems to see if they could figure out what was wrong. I was able to get another licensed heating company out the same day. The other company's tech confirmed that two of my systems were operating exactly as they should which was confirmed by my tenants. The unit that I called about needed a new transformer and it fired right up without issue and the tech confirmed all 3 units were operating safely. Zeolla operates akin to a dishonest mechanic or a surgeon doing unnecessary surgery, and these guys should be investigated. The worst part is that they were willing to let my tenant go without heat for an extended period of time in order to con me.
