I was considering changing my boiler for a new one as I wasn't getting adequate heat in the bedrooms and thought maybe the boiler was crapping out due to its advanced age. I called Mastersmind HVAC and Chris swung by the following day and recommended that they run a diagnostic on my existing boiler to determine what was causing the problem and further to determine if the boiler could be salvaged. He and his partner showed up and wore shoe covers when they entered my home; they performed a thorough cleaning of the boiler and were able to troubleshoot the issue. Instead of selling me on replacing my boiler like other companies have tried to do, Chris recommended a cheaper fix as he concluded that my boiler had another 10-15 years of life. I can attest to the integrity of this team of caring and hard-working professionals. I would recommend Mastersmind HVAC to anyone! read more

I can't say enough good things about the service I received from MastersMind. My central AC went down yesterday, Wednesday 9/5 in 90+ degree heat, and this afternoon (Thursday,9/6), the problem was solved. The owner, Chris Cosentino, assessed the situation personally, diagnosed the problem, took the time to explain to me exactly what the problem was, how it related to how the AC unit worked, and what needed to be done. He even advised me on how to prevent the problem from occurring again. Chris and team recognized the urgency of the situation, and the concern I had for the comfort of my three kids, and made my job a priority, for which I will be eternally grateful. While I personally hope to never need MastersMind's services again, I can, with great confidence, recommend them to anyone with an HVAC need. read more

I must agree with the other reviews. I rarely give 5-stars, but Chris really is the best! He is efficient, upfront and communicates well to let you know what your options are. I called him to install an HVAC system for my place. I had ordered the wrong machines, not only did Chris get in touch with someone who could provide me a STEAL, it ended up being cheaper than the original amount I paid! Before coming he called to let me know he was on his way, showed up right on time, got right to work, did a GREAT job and even tightened/cleaned up a few things he didn't have to to help prevent another problem. That kind of honesty and pride in work is rare, but extremely appreciated, I hope he stays in business a long time. I'll be a life-time customer. read more

Chris, Selly & Stephen are fantastic. From the initial consult to the final work, these guys were a pleasure. I had a Mitsubishi provider give a quote before Chris & he assessed our place with an idea of how he could best fit the products he had to sell. Chris viewed our home and gave us product and installation options and voiced his opinion on what he would do if it was his home and why. I'm not an hvac expert, so Chris's thoughts about the pros and cons of different types of installations and placements were really helpful to hear and he was able to work within our budget. And then Selly and Stephen came to do the work. You couldn't ask for two nicer guys. They were quick with their smiles and thoughtful about their work. Five stars all around. read more

Chris is an outstanding HVAC professional and an even bigger human. I called him out of the blue with an emergency on a cold Sunday afternoon in my Brooklyn Home and he showed up a few hours later and even brought shoe-sleeves to not track in any unwanted germs in my home. Funny how that's a house rule for me and he did it without me having to mention anything. Before Chris, 3 other "professionals" showed up at my home and could not rectify the issue. Within 5 minutes Chris not only fixed the problem, but he updated my system and wrote me a "to-do" list to keep my system running at optimal potential. I have greats plans in store for Chris and Myself and I simply cant wait to commit to them. Excellent service! So grateful. read more

I recently purchased a Panasonic Mini Split system and had the most difficult time finding someone who would install it. Luckily, I was put in contact with Chris. From our first conversation, he was friendly, thorough, professional, and obviously very knowledgeable. He clearly explained everything to me, laid out potential costs (along with ways to save money), and answered all of my questions. He was always very responsive and set up the job very quickly. Chris and his technicians arrived on time, worked quickly, did a brilliant job on the installation, and cleaned up when they were done. I will absolutely refer MastersMind to anyone looking for HVAC work and will be calling Chris again in the future. read more

Chris and his crew were unbelievably quick, responsive and had no problem doing anything I asked. I am a very particular client. I have used several HVAC companies but none were like mastersmind HVAC. They really aim to get it right and figure out the solution to the problem rather than quick fixing the symptom. Chris is a great guy who went the extra mile to fulfill all my requests. He is very responsible and does what he says. His prices are very reasonable and he is extremely competent. His reports are superb and his inspections are extremely detailed. If you are having problems with your HVAC, you owe it to yourself to call this company. read more

This is a really great company. Their service is wonderful. Chris called me right away about an AC problem we were having. He was very professional and asked all the right questions over the phone. He sent someone out to our place right away. Alexi was great. Very nice and professional and really took his time figuring out the problem. He even showed me the HVAC unit and how it worked. When they had to come a second time because the AC still wasn't working, they were very nice about it and Alexi figured out the problem. The AC works beautifully now and Alexi and Chris couldn't have been nicer. read more

Chris is very professional and ethical and an expert in HVAC systems. I highly recommend! - He showed up in a timely manner for an urgent repair call during a hot Memorial day weekend. - He quickly identified the issues with the system, and referred me back to the installer, so I could benefit from the warranty. - Even with two visits from Mastermind and a few hours spent on the job, he was a gentleman and did not charge me for the diagnostic. - He took the time to walk me through the system and issues and his recommendations which I found very helpful. read more

Chris and his team are really a class act. Professional, honest and extremely dedicated to finishing the job to perfection. I cannot say enough great things. They came to fix my a/c unit that had multiple issues and stayed until late evenings to get it done. Throughout the process, they were extremely communicative. Chris spent hours upon hours of his own time trying to get in touch with the manufacturer of my original unit in order to get a resolution (which of course he did). We are very satisfied with working units now thanks to Mastersmind! read more

NOTE: They ARE NOT closed Chris and his brother Neil (family business) came to clean and provide servicing on our Fujitsu mini-split HVAC cooling/heating units (3). They also fixed the Carrier gas furnace in our basement. They are very knowledgeable and worked quickly/cleanly. Totally worth the price point considering the unprofessional job done on the installation of the units and other companies we've used in the past. They are honest, professional and thorough. Highly recommend Chris and the Mastersmind team. read more

Chris was fantastic. Our heater stopped working a couple of days ago. I called Chris and he helped troubleshoot over the phone. He did not end up having to come to the apartment to look at the heater. Saved us at least 100-200 dollars, which is what most people would have charged just to come look at the unit. It's rare that you find a company that actually wants to help you, even if it means sacrificing the fee for a house call. I'd recommend Chris without any hesitation. read more

I'm surprised by the negative review here. I've relied on MastersMind to remediate and maintain my (originally, poorly installed by others) house AC system for years now. The company founder is thoughtful, intelligent and truly customer-oriented, offering clear explanation, reliable follow-up, and good communication. Team members are skilled, diligent and courteous. Pricing is reasonable and reflects high-quality service, always a good investment. Highly recommended. read more

Mastersmind installed my mini split heating/cooling system for several rooms in my house. Totally professional, totally honest! An awesome job at a reasonable price, and attention to all the details. On a couple of occasions Chris helped me without a service call, when many others would not have done the right thing. Total pros who did a great job with the installation and any questions I had. I am so happy I used them. 100% recommended! read more

I wish I could give Chris and Masters Mind HVAC more than a 5 star rating. My heat went our over the coldest weekend of the year. My family woke up to a 53 degree apartment. I contacted Chris who drove down on a Sunday from his vacation upstate to make sure the heat was fixed. Service and expertise like this is very rate in today's world. I recommend using Masters Mind HVAC in the strongest way possible. read more

Chris and his guys got us out of a couple of tight spots in the last year! They got the mini splits back up and running super quickly in the coldest of times this January, saving our tenant from freezing. They also came in and fixed a poorly installed system last summer. Plus, they are meticulous about their work. We trust them completely and will be having them back to install more units as soon as we can. read more

Chris and his team were fantastic -- they replaced a unit last year after another AC repair guy left in the middle of a botched job and stopped responding. So they fixed that guy's work, set up the unit, and came back for a free tuneup ten months later when we were within the year warranty. Extremely responsive, professional, and easy to work with. read more

Exceptional service from Chris at Mastersmind HVAC. We needed routine maintenance and cleaning of our apartment's central AC unit on a tight timeline. Chris fit us in day of and is clearly expert at his business. After bad experiences with other HVAC companies, it's incredibly refreshing to have such a great experience with Mastersmind. read more

We were looking to relocate a/c condenser unit. Discussed the project with the owner, Chris. Found him to be knowledgeable and detail oriented. He walked us through the procces beforehand, was punctual, relocated the unit as we discussed and left the work area neat and clean. Couldn't ask for a better experience. Solid 5 stars. read more
