Oct.2026 to prepare for winter heating season, I called Anna at Arnica Heating & Air Conditioning - AUTHORIZED DEALER for my Burnham boiler. Immediately she scheduled maintenance on the boiler they successfully installed in Spring 2026 (my previous boiler broke on a frigid day). What a relief to see the very capable Mr.John check that all was in good order to have a cozy home. Feb.2026 Arnica Heating & Air Conditioning skillfully repaired my Burnham gas boiler. THEY ARE AN AUTHORIZED DEALER and dealer, their expertise was obvious. My 20yo boiler gave up on a frigid -5º Super Bowl Sunday. The very next day, their plumber repaired it it and Arnica's quote for a replacement boiler beat out the competition. A week later, their crew efficiently removed the old unit and installed the new boiler. Between their professional, kind service and 24/7 live call center, I'll confidently use them for all my annual maintenance. read more

I have been very happy with the professional and rapid response service Arnica has provided me over the last eight years. Simone personally visited my Manhattan Co-Op apartment and offered the perfect solution for a new HVAC split-duct system. I find him and his entire staff very knowledgeable, professional and ready to help. The administrative staff helmed by Rosette Lauro is the best. I recently needed to replace the remote control for my Mitsubishi unit and she was able to quickly track down and have shipped out a replacement. If you have any HVAC needs, do not hesitate to call Arnica. They will take very good care of you !! read more

prompt response, came to evaluate condition of my HVAC unit and fixed the problem. Overall provided a good service. read more

We scheduled an appointment, they called to verify the time of arrival that morning and showed up on time! Very efficient and respectful of property. read more

I have been an Arnica customer for years. After recently having our a/c serviced, one of our units needed attention. They sent a tech quickly and addressed the issue promptly. They stand by their work and I appreciate doing business with them. read more

I'm an architect in Brooklyn. In my 30+ years of practice in NYC, I've dealt with many HVAC contractors, but Arnica has risen to the top of the ranks. Simone and his staff are friendly, professional, and knowledgeable. I've lost count of how many jobs we've done together. When it came to installing new heat pumps in my own house, I chose them. This last year, they installed 3 condensers with 14 interior zones (ceiling cassettes). It's all working beautifully, even through the depths of winter. I can't recommend them enough. read more

Great people, great business! My partner and I were doing a full gut renovation of our 3 family townhouse. We found Arnica on the google machine under green energy incentives. We first got a visit from Simon Arnica himself. Warm, friendly and quite knowledgable. His office gave us the same friendly energy. Once we were ready to install our new mini-split system, his crew showed up on time, was very professional, and their work was immaculate. We were working with a high end contractor, and he said that they were one of the most impressive HVAC companies he's ever worked with...mostly about the quality and way they handled their business. Later Simon's son Dean came and made sure the work was done properly. We have had our new minisplit system in place for 2 years now, and it has been wonderful. No issues, just living in the comfort of our new home. I highly recommend Arnica. They are a family and I believe they bring that integrity and personal touch to every project. read more

BEWARE BEWARE BEWARE I called this company to fix my AC. They were not able to fix. They actually damaged the unit then tried to sell us another one. After we declined they only repaired what they broke then tried to charge $3100. Then they send their attack dogs from billing to spray with calls. This business has unethical business tactics. read more

I called them to see whether they can help with the issue I am having. No interest what so ever in even listening. "I can send you someone to come over for a visit. It will be $ 199 for the visit and $ 199 for the diagnostic" No one charges for the visit, the most is $ 150 and even then it is something you can deduct from the work. These guys want $400 to come say hello. The problem with these super simple units are so standard and so few, they could have listened and sent the right guy to fix instead. Their greed however wouldn't be satisfied in this case! read more

Good people...good work I live in Manhattan and had them install a split level Mitsubishi system with 2 compressors, 2 wall mount vents and 2 ceiling cassettes (the ceiling cassettes are awesome!). I would say the install was complicated as it took some custom work to mount the compressors and all the piping was done internally (not outside). They did a great job communicating through the process. The office and installer staff were super polite, courteous and helpful. Simon worked hard to accommodate the electrician's needs and made a strong effort to keep costs down. After installation, the system needed some minor tweaks, to which they quickly fixed. Great experience and I would recommend them. read more

Professionalism and service are both 5 star. I have an apt in the city, but live in Florida. I am only here part time. With that being said, communication is key to coordinate time of service. Arnica Air was excellent! They were on time with all appointments consisting of diagnosing the problem, ordering the part and repairing my AC. Extremely knowledgeable with service and fixing my AC. Highly recommend! read more

Super good service I'm very happy with everything. Very responsive and fairly priced. I had just bought a new home and needed a replacement furnace. They came through priced it out and got the job done quickly and efficiently. Fantastic followup/followthrough and I feel very secure that our new HVAC system is going to work very well for a long time. read more

Arnica was great on install of new central a/c. Simon was very responsive, helpful and honest. Lisa handled appointments and documents very effectively. The tech who has done two annual routine maintenance jobs for us was knowledgeable and very willing to explain to me what he was doing. A very good experience with Arnica! read more

I had 2 AC-related needs at my apartment: a new AC installation to the existing Mitsubishi system, and also older units started leaking water, so I called Arnica for a maintenance visit as well. Simone came in for the initial visit, answered all questions and gave me installation options. Jackie from the office was very helpful with paperwork needed for our co-op management for a new AC installation. Anthony came in for the maintenance visit and did a fantastic job. He cleaned all the units thoroughly, gave tips for future maintenance and was very friendly and polite. Paul and another technician came for the new AC installation, they were on time, efficient, quick, did a great job, then helped with the cleanup too. My only wish that they had availability sooner, but I understand that it's the busiest time of the season. Overall, I had a great experience, everyone from the team was very professional, my AC system is working well, and I would recommend Arnica to others. read more

After screening a wide variety of HVAC specialist in the NYC area for the extension of my new business space's HVAC unit I was thrilled to receive such professional conduct and consideration from Arnica! From the incredible response time from the main office (Jackie is phenomenal at follow-through and getting you answers) to onsite visits actually on-time, not a 2 hour window, no, actually on time! Simone runs the show and does it very well. There's a sort of three-step process: Step One: Simone sets up a time that works for you to arrive on-site for a primary walk-through so he can had the right techs come out for the next stage. Step Two: Simone's team of installers visit on-site to measure and give a more accurate outline of buildout/HVAC needs - they were also on time and very quick to get the info they need. Step Three: The final quote is built off the installer's feedback, which Simone walks through with you, you then make the decision to approve before setting up the project scope. These steps were all at no cost as it qualifies as your consultation. If you have a heating & air project of any degree I would highly recommend Simone and his team because of their dedication to precision and quality work. read more

After 50 years of service from my old gas furnace, I was uneasy about navigating the new world of residential heating systems. Living in a four story brownstone added to the challenge. Simon was able to recommend and install a system strong enough to service all floors adequately and use the existing duct system. So far, we are satisfied with how well the temperature remains consistent throughout the building. The Arnica team members were courteous and respectful. We plan to use Arnica going forward for all our maintenance needs. David O. read more

Excellent company and leadership with excellent technicians. They worked on a split unit in a condo building .They did an immaculate work.Highly recommended. Thanks read more

These folks are the absolute BEST! The office staff is incredibly friendly and pleasant, and they make appointments that the service people actually keep. The service people go above and beyond - they are professional, they know their jobs, and they are very friendly too. Total respect for your home and for the customer. A++++ all the way. read more

Had Arnica install my Mitsubishi Split System about 3 years ago with no problems whatso ever in that time ( By the way I Love this system) Then the condensate pump begin coming on every hour for 5 or so minutes at a time making a vibrating,grating sound for no reason ( it was winter and I wasn't even using the system) Techs came to see it and left with no prognosis,while another two weeks of pumping noise went on. Then Arnica had Neil come out and the pump was not working correctly so he installed a new one in the closet where one of split units is upstairs on an intereior wall. Back to normal now.. I can sleep again. Yay. Thank you,Arnica. read more

Replaced a 50 Gallon hot water heater quickly, cleanly, competently, politely, and at a fair price. Just what you want, but rarely get in NYC. read more

I used Arnica Hearing and Air Conditiong to install my multi zone units. Alex and Mario did an excellent job with the installation and were very professional and cleanliness. Rosette was great with the scheduling. I would recommend them if you want a job well done. read more

Arnica did an excellent job installing my ductless split unit system. They can go my home to provide an estimate and we scheduled a date to install. The team at Arnica is wonderful to deal with and they took we y opportunity to answer my questions and provide documents I needed for my cooperative. read more

So this is the second time we chose Arnica Heating to replace another PTAC system in our apartment. Just like before, the installation went smoothly and both systems are working great now. read more

I wrote a pretty tough review of these guys, they had a scheduling that messed stuff and they couldn't come when they said they would. I feel like I need to update it now. I got a call in the evening from Simon the owner, who really wanted to make it up to me. Next day, he sent Jay, who was a great guy, to take a look at the unit free of charge. Not everything goes smoothly, but fixing a problem is a hallmark of good customer service. Pleased, and would call them again. read more

This is my first review, but my third service call from Arnica. They were very prompt and professional. The first call was about a strange smell coming from my Mitsubishi split system. They came and showed me the dust and grime all over the coils, cleaned it all up, and showed me how to do it myself. I was so pleased I wrote down their name to remember to call them in again, which I did; not for a smell, but because I saw a lot of dust and what I thought could be mold inside the unit; so I did not feel comfortable cleaning it myself. Again they were prompt and professional. But you get what you pay for, and they are not inexpensive. It cost $150 to clean the filters of one unit, and I have six. I will be calling them back again next year. read more

Arnica might not be the cheapest company out there but their service and expertise was worth every penny. They were able to get knowledgeable technicians out to our building in 95 degree heat on a Friday night within hours for an emergency call and diagnosed problems that other HVAC repair contractors couldn't. It pays to work with professionals. read more

Last Month When we had those Freezing Arctic Temperatures my 18 yr old Furnace decided to Breakdown.. We were in a Pickle, The House was FREEZING !! I called Arnica.. Within a few Hours a Technician was at my house.. Tech told me it was my Blower, which he happen to Stock on the Truck *** GREAT PRICING ***** EXCELLENT SERVICE!! THANKS ARNICA! HIGHLY RECOMMENDED !!! read more

I did a lot of searching for a legitimate HVAC company for my PTAC unit that needed repair. The experience was smooth from start to finish; they were very professional and I even spoke to the owner, Simon, at one point, and he was very kind. I had messed up my certificate of insurance and had to reschedule w/ Arnica even though the technicians were already on their way to my apartment; they were all understanding and we just worked out another day. Certificate of insurance was returned very quickly to me, which made the whole process easy and smooth. Jay the technician was intelligent, hard-working, courteous and professional! Highly recommend for those in search of a legitimate company. read more

I was very frustrated when I called Arnica, they had been out less than a month ago and the a/c at our office stopped cooling over the weekend. I reached the answering service but the owner (I assume) called back to say he would make sure someone got out to us the next day. Sure enough, the same knowledgable technician, Jay was in our office by midday Monday (today.) Turns out the unit needs a new motor which will be installed tomorrow since he has to pick up the part. I can't recommend them enough, efficient and courteous customer service. I will continue to call them for heating and cooling needs and recommend them to anyone. read more

Had a new boiler and hot water heater installed. Their representation from the Owner, techs and office staff was professional and courteous all the way thru. The price was fair and the installation went off without a hitch, the cleaned up well after themselves and ensured that we fully understood the process as it was going on. read more

Arnica replaced my old, inefficient A/C with a new Mitsubishi HVAC mini split system. The entire team from owner, to office and installers are professionals and experts. They were all extremely knowledgeable, friendly and responsive. Particularly for those living in Manhattan apartment buildings who want to have control over their own apartment's temperature - Simon and his team have years of experience working with the challenges of NYC apartments. They stand behind the product and their work. I would definitely recommend them to anyone looking for new heating and cooling solution. read more

They have a sleazy business model. They quote you $99 for the service call (applicable to the work), and then give you a very inflated quote for both parts and labor on the work itself. On the other hand, the tech seemed all right and they came the same day. Still, this is one of those deals where you feel screwed halfway through. I wouldn't do business with them again or recommend them. read more

Although they were busy ,they found a slot for me the next day. My tech was JAY. He was prompt and quite courteous . He found my a/c problem although it was a tight spot to access , he never complained and kept a smile on his face .A beautiful job done cleanly and properly . Prices were good and it's cooler than before now .Highly recommended and ask for Jay. I'm sure they are all great but it seemed like Jay is a customer appreciating kind of worker. That reflects well on the company. read more

We called Arnica Heating in Staten Island on a Sunday night, and they came within the hour to check out our heating system and diagnose the problem. They came back on Monday and installed our new furnace. The crew was courteous, neat, friendly and helpful. They explained everything to us and were extremely professional. We've used this company many times before and are always satisfied with their services. read more

Excellent experience with this company. Professional, efficient, and very nice installation. Highly recommend!

I just had Arnica install the newest model Mitsubishi ductless mini split system in my NY apartment. The install was not an easy one and other diamond contractors shied away from the job. My installer was Paul who managed to shimmy out on a slanted solarium rooftop 5 floors up and securely mount a large 130 lb. compressor. He also went out of his way by concealing the unsightly line set behind my walls. The Arnica team cleaned up after the job and went out of their way to clean up the mess left by the electrical team. The completed installation looks pristine and the amount of cooling these units produce is magnificent. Many others in my condo building on East 86th Street have used Arnica and are just as pleased. The owner Simone is hands-on and very involved in all aspects of his installations from start to finish and he continues to remain involved for maintenance down the road. Don't think twice about hiring them as they get the job done and are hassle -free. read more
