The team at Airnizer are excellent. I recently had a mini-split unit installed in one of my rooms, and a separate cleaning effort for multiple mini-split units. They are extremely responsive through text and phone calls, providing all details and cost breakdowns so there aren't any surprises. The pricing is on par with competitors in the area. As for the work itself, the team was prompt, showing up at the earlier end of the promised time window. They were efficient with both installation and cleaning efforts. The installation went seamlessly and flawlessly. Overall, I would absolutely hire Airnizer again as they provide an excellent level of communication, responsiveness, and overall service quality. read more

Excellent service and communication throughout. Max responded promptly to my Yelp request and scheduled Oleksandr for a next-day visit. Oleksandr was extremely knowledgeable and fixed our heating issue quickly. I highly recommend this company. For context, we had hired another HVAC company two days earlier, and they were unable to diagnose or resolve the problem. read more

Airnizer recently installed Mitsubishi minisplit units in our townhouse. They were responsive and professional through the whole process, from the initial visit through installation. They had creative solutions to address my concerns, the installation went quickly and well, and they were very clean and took care of our things. Highly recommend! read more

Airnizer did a great job in fixing our noisy heat pump. We had a unit on our roof that was rattling our whole bedroom below, airnizer came and switched motors around on the units up there and problem was solved. They even saved us money because we didn't have to buy a new motor.. read more

Our AC went out during the spring, which is what prompted us to call Airnizer HVAC--and I'm really glad we did. They came out quickly, were very responsive over both phone and email, and handled everything in a professional manner from start to finish. Their pricing was reasonable, and they were upfront about costs. They diagnosed and solved the issue swiftly, which was a huge relief given the heat. They also made sure to provide a COI, which we needed for our building, and they accept multiple forms of payment, making the process easy. Overall, a smooth, efficient experience. I'd highly recommend their services. read more

Service call 11 months after installation cost $300. Turned out all I needed to do was press one white button inside the PTAC and then press another one. The guy who arranged the service call could've told me that over the phone. read more

Very responsive and was able to get the service call scheduled the same day. Very professional and was able to identify the issue right away. They did a full check on our HVAC and everything is in good working conditions. read more

I called Max recently during a February cold spike about my heater. He was honest and fast. One of his competitors was quick to send me an estimate for $7k, saying I needed a new heater--when in fact I only needed one part. I called Max. He arrived the next day and gave me a no b.s. quote that was fair. Within a few days he had the part he needed and quickly fixed my heater. Nice guy. Efficient. Honest. Rare qualities these days. If you have an issue with your HVAC, give Airnizer a call! read more

I never leave reviews, but wanted to shout out Airnizer for their amazing work on my mini split replacement. The team was very responsive, provided different options for repairs/replacements at various price points, and ended up completing the project in less time than anticipated. They were also very careful not to damage my apartment. I would gladly work with them again and have already recommended to others. Thank you! read more

I really like these guys. This is my third year using them- I've had various problems throughout the years for my water pump AC and they have always been able to figure it out and fix it. They are honest and conscious of pricing, they offer an estimate before they do anything. The servicemen are professional- I never feel like I'm being spoken down to, they take time to explain the problem and what they are doing to fix it. They know what they're doing -highly recommend. read more

Vlad did a great job bleeding my forced hot water system, my house is warmer now than it's ever been!

I can see why they get high marks. Boiler was cycling very fast in this cold weather, wasn't sure if there was a reason that needed fixing. Quick response with available times posted in message. Able to get service by the next day. Arrived on time. Patient and discussed workup etc.. Average cost for home visit $200 read more

Great pros and very competitive offer - customer service was spotless and ultra responsive

These guys are an absolute life saver!! They helped fixed the heating on my unit. Second time using them and i can't recommend them more than enough. They went above and beyond. read more

We've called on Airnizer twice now for our HVAC unit. Both times the experience has been exemplary--quick initial response, visit the next day, good work. Though I hope the unit doesn't break down anytime soon, if it does. we'll be calling Airnizer. read more

Airnizer was able to come the next door to service our unit and we're quick, thorough, and professional!

During the peak of the heat wave, our AC suddenly started blowing warm air. After reaching out to four different companies with little success, Airnizer was the only one that responded quickly, communicated clearly, and actually diagnosed the problem thoroughly. Our condo uses Trane central air units that most residential technicians aren't familiar with, which made the situation even more stressful. Max, however, was outstanding--always responsive by phone or text, and he took the time to explain what was happening, what the diagnosis was, and what parts/repairs would be required. Oleksandr and Sergey, the technicians, were equally excellent. They arrived on time for every visit, were professional and communicative, and handled multiple rounds of repair with precision. Importantly, they managed to repair everything on-site without needing to remove the unit, which saved a lot of hassle. While the repair ended up being on the pricier side, the level of professionalism, transparency, and assurance we received made it stress free for us compares to the nonstop back-and-forth and unclear exchanges with other HVAC repair companies we dealt with. Every step of the process was documented in writing, and I felt confident that my tenants and I were in good hands. We'll definitely be using Airnizer for all seasonal and routine maintenance moving forward. If you want a team that is responsive, thorough, and highly professional, I can't recommend them enough. read more

We've used Airnizer for over five years now. They are easy to communicate with, responsive, and provide the certificates of insurance and proof of worker's compensation that our coop board requires. The A/C units are clean and functional after their maintenance and we can trust that our children are breathing healthy air in the apartment! read more

Vlad came and serviced our 54 year old gas furnace system. With the parts replaced and maintenance performed, it runs like brand new again! He came in a timely fashion and serviced the job very well. I would call Airnizer back in a heartbeat to service my system again. read more

Im so grateful that I found Airnizer on Yelp! What a positive experience from start to finish! The compressor in my vertical HVAC unit died on me and had to replace the chassis. The HVAC company that my building (very large building with multiple units) uses gave me a quote with a lead time of 7-8 weeks (which is basically the whole summer)! Max, the office manager was deeply knowledgable and surprisingly frank and honest. He was upfront with every issue and detail. The other company was not, which made me appreciate Airnizer even more. They came out the very next day to do a diagnostic test. A couple of days after that, they found the Climatemaster brand components in stock (which was apparently difficult to procure from the other companies) and installed the parts. I have to mention that the tech, Vlad, was incredibly skilled, efficient and meticulous! So helpful to boot--walking me through the work and instructing me on what I needed to do to maintain my HVAC in optimal condition. Now, I have to share my wonderful experience with Airnizer on my building intranet board! read more

Amazing service. I needed my split unit a/c deep cleaned after what looked like years of buildup. I contacted a different company previous to hiring Airnizer, and all they did was spray chemicals in my outdoor unit and rinsed the indoor unit filters under water. Said they don't take split units apart, so after some research I contacted these guys and they did an incredible job. Took the unit apart piece by piece and thoroughly cleaned it. Unit looks brand new and I no longer sneeze when the a/c is on. very quick, precise, and professional service. won't be going anywhere else. read more

Airnizer was great! I sent a Yelp request on Sunday afternoon for a broken water heater and by Sunday evening they had scheduled the on-site inspection for Monday. They were able to quickly diagnose/confirm the problem and confirm the replacement parts. They even said they could come back Monday evening to repair but I had plans, so they came on Tuesday morning and were fixed by 2pm. Very happy to have my hot water back in ~48 hrs total. Vlad and team were professional, courteous, and cleanly and easily communicated via text message. I would highly recommend them to others! read more

I had used Airnizer a couple of years and they came and cleaned my system with no problems. Last year the told me it was time for a deep clean. This lead to a multitude of problems. They sprayed some "solvent into the system", to clean it and it clogged everything up and busted three of my units which had been working perfectly before the deep cleaning. Basically they charged me a fortune to do the service and all the repairs. They have no idea what they are doing. each time it cost me for the visit and the repair. i ended up having to replace one unit, tear up my ceiling and walls. And now the other units they said they fixed is making a crazy sound and I have to repair or replace that unit as well. Do not call them. they have no idea what they are doing and it will cost you more in the end. read more

I am satisfied with the quick responses and professionalism of Airnizer. I would recommend that those in need to first consult them.

They removed our old AC and heat pump system and installed a new one using the existing ducts. Excellent work, excellent communication, highly recommended. read more

Contacted Airnizer HVAC after 8 PM on Yelp to replace a steam boiler circulator pump for a basement. A company POC responded right away. The business response included the exact diagnostic fee and provided 3 to 4 time frames to choose for next day service. HVAC Airnizer kept me informed by phone, text and email throughout my engagement with them. Vlad did the work agreed upon satisfactorily and provided cleaning recommendations to remove rust and sludge from the system. I just wish their prices were a tad lower. read more

Vlad P was very polite and helpful. Serviced quickly and suggested how to maintain our water heater. Got to the root of the problem. Pricing was what was quoted. Also suggested how to maintain our boiler system. Serviced in East Harlem, Manhattan. Sarah read more

I requested a quote to replace a 1 ton Mr. Slim condenser and these guys wanted $2,500 + just for labor.....COMPLETE HIGHWAY ROBBERY!!!! I've received quotes from other contractors which include the condenser for that price. read more

A great team to work with. Very precise and responsive. Would def. recommend them. Thank you!

We had an amazing experience with Airnizer. They helped us when our thermostat broke. Everyone was very communicative and responsive. Would highly recommend! read more

My furnace went out and they came within an hour of calling. The technician, Max F., was outstanding. Quickly found the problem (bad igniter) located and installed the new part and checked for any other potential issues. Up and running just four hours after my initial call requesting service. Price was very reasonable as well. Highly recommend. read more

Very professional and got the job done well + quick. Would use again. See you all in a few years.

I was having an issue with a Mitsubishi air handler unit that another large Brooklyn HVAC service company said required new parts (3-6 weeks to be delivered!) and would cost over $1500 to fix. I called Airnizer for a second opinion and Max sent over a technician, Vlad, that same day. Within ten minutes, Vlad had identified the ACTUAL problem and was able to fix it on the spot - no ordering parts and no crazy fees. Clearly Airnizer hires technicians who know what they're doing. I would highly recommend them and will be using them for all of my HVAC needs from now on. read more

We had a mini split system installed this week. Sergey and his team did a great job. Everything worked out just as they said.

I got my mini split ac unit deep cleaned and Vlad was very thorough. He did a very clean and great job!!! Working with my other ac guys they are always so rushed and I always felt like inwas being scam etc but Not this company they were very transparent with the price and again the job felt not rushed and done with proper honest care I recommend them for your ac unit cleaning! read more

Have had a great experience with Airnizer two separate times now. First they came to provide maintainance to my apartment's HVAC. They came on time and explained everything they needed to do. The second time, the AC stopped working out of nowhere and they were able to squeeze me in in only 24 hours notice to come check out the problem. After finding it was merely a switch flipped in the circuit breaker, they didn't even charge for their time. It was so gracious of them... highly recommend their honest service. read more

I am always so very impressed with the quality of service and professionalism! Vlad is a miracle worker who has gotten my aging Fujitsu split-duct system to work perfectly. He is also now doing the servicing on my boiler. Airnizer is top-notch, definitely worth every penny for the incredible skill, knowledge and reliability. read more

Airnizer's visit charge is $300 and can be applied to the work that they can then do afterwards if need be. Picture this: They arrive, charge me $300 (where others charge on average half or less that amount) and then inform me that a nitrogen test will cost $2500 plus MORE per line, up to $6500...just for a test! This exact test (I learned later) costs between $250-$650 by ALL other businesses. They clearly were stating that "we need to do this test otherwise you lose your $300". I chose to do the sealant test instead that was going to cost $850 instead. However I was never properly informed that there was a chance that the system could break down completely instead. To be clear, my system was working ok at around 60F (see photo) and two days after they applied their sealant the system stopped working completely (81.5F - see photo). I was never ever informed that there was the risk that the system could completely die. All I was informed was that there is a chance that the sealant wouldn't work. Period. Airnizer is an over-priced HVAC company that pressures their customers to pull triggers on high spending costs during heat waves. I recommend that everyone do their due diligence before asking Airnizer to come to their home or business. Look at their pricing and compare it to what is FAIR and not the exorbitant pricing they offer. My biggest mistake was to trust the 5-star reviews when what I should have done was make sure that the pricing was not a ripoff. My new HVAC company (DC AirHVACR) charged me a FRACTION to TEST my system with the nitrogen test and it's costing me LESS to replace the entire system that Airnizer broke than what they wanted to charge me for JUST the nitrogen test. When someone asks you to pay $300 for their first visit and you're forced to make a pricey decision, otherwise you lose the $300...it shows that they do not care about YOUR needs. They care only about their wallet. 2-stars... only because the techs were kind. read more

Eugene, Vlad and their team are top notch. If you are looking. You can stop. They are responsive, accommodating, honest, timely and tech forward. I have an old combination water heater boiler that they have assisted with every step of the way to keep it going and keep my tenants happy. When I need them to act fast, they are always there. When I eventually replace my unit. I am calling them. I am an Airinizer client for life! Thank you, thank you! read more

They showed up to fix a broken boiler for our hot water baseboards. Quickly identified the issue, which was a replacement of the pump and expansion tank. Went to get parts and had the issue fixed same day. read more
