Thank You keepcoolnyc.com I appreciate your quick response to our request to install AC. It has been two months since the installation. It runs smooth and very good installation service from initial AC requirement analysis to installation. We appreciate your service! read more

Keep Cool installed my wall-through AC unit. We prepared the sleeve and then the KC technician came and unpacked the AC, inserted it into the sleeve and sealed around it. Not complicated and I probably could have done it myself but it was worth the $100 to make sure it was done right. If you need a Certificate of Insurance it's another $20 but you can process it online and it comes fast. Dave at KC was excellent. He responded to emails promptly and the technician showed up at the very start of the 3 hour window I was given. They were the most responsive and cheapest of the several quotes I got. I would definitely use again. read more

I've used Keep Cool NYC twice, and have been so grateful each time. The first was in June 2020 - definitely an uncertain time - when I needed new window units that I'd purchased installed in two windows in my apartment. I was so impressed with their responsiveness, efficiency, and the work that they performed. They also took safety precautions at the time quite seriously which I appreciated, as it was a scary time. Fast forward five years, during the record-breaking June 2025 heatwave in NYC, and a friend who was staying in my apartment reported that each unit was having issues. The bedroom unit was leaking into the bedroom and had to be shut off; and my downstairs neighbor reported my living room unit was leaking into her apartment. In spite of the heat wave, when I'm sure they were busier than they'd ever been, Dave responded immediately, and diagnosed that the bedroom unit was probably clogged (I'd left it in the window for five years) but could be repaired. And he perceived that the living room unit was likely *not* malfunctioning, but working as expected, and it was probably an issue with the downstairs neighbor's window. In spite of the heat wave and how busy they must've been, they were able to come out within a day, and Dave's initial expectation was right on the money. They were able to fully clean and repair the bedroom unit, which is back to good as new, and help diagnose the perceived issue with the living room unit. Indeed, it was a problem with the downstairs neighbor's window (and she would've been vulnerable for the same reason to rain or any other external water), so the super is on the case for that. The prices were completely reasonable and I was only charged for the one repair, at the quoted price. A week after the repair, Dave was kind enough to reach back out and check to make sure everything was going OK, which I really appreciated, in addition to how quick he was to response and service the units. So grateful to Dave and Keep Cool NYC - thank you so much! read more

I've had several AC units installed at my apartment over the years. While I have done DIY AC installs in past apartments, having someone come in and make sure everything is installed correctly, for piece of mind, is priceless. Keep Cool NYC's techs are always professional and fast. Prices are reasonable/affordable. They've been my choice for years and my recommendation to others. I left the same review on Google reviews if anyone sees it there, but some people prefer one platform or another so thought I'd give my two cents on both. read more

Keep Cool NYC personnel truly know air conditioners and they charge very reasonably for their work. On July 28, 2024, a technician named Roman came to my home and did a beautiful job installing an 8000 BTU Friedrich inverter AC, model CCV08A10A, into a 39 and 5/8" wide window frame, which is wider than the maximum width for which this model was initially designed; to accomplish this installation, Roman expertly cut on site and then attached to this AC 1/8 thick polycarbonate side panels. Working with Roman and with everyone else at Keep Cool NYC, notably Maria and Dave, was an enjoyable experience. Accordingly, I have used Keep Cool NYC two more times since the above installation. In November of 2024, due to the impending winter, I needed to remove from the window the AC that Roman had installed therein on July 28, 2024. On or about November 4, 2024 I contacted Keep Cool NYC again and arranged for Roman to remove this AC, which he then promptly and efficiently did. Thereafter it became summer's turn to be impending, so I arranged with Dave Messina for Roman to visit my home on May 21, 2025 and reinstall this AC and also install in another room two units I had recently purchased of the same model AC. As always, Roman did all this work expertly and, also as always, Keep Cool NYC charged me very reasonably. read more

Great service. Professional and they did a great job. They were responsive and fairly priced. I would hire them again.

Very affordable and my ac was installed very fast which was nice but there are gaps between the foliage and ac unit and holes to the outside which can let pests in so now I'm having to figure out how to solve this problem read more

We had Joel as our technician. 10/5 stars. Professional. He got in and got out. Installed it in real quick $215. No hassle no mess. Very good job from what I can tell! read more

I chose Keep Cool NYC due to the many favorable reviews, and their experience with installing Midea u-shaped window ACs. The technician Roman did a great job. I splurged and paid extra for plexiglass and a custom brace. It was worth every penny! The plexiglass allows more light and I'm able to open the window. I highly recommend Keep Cool! read more

Technicians came Thursday the 29th, and have to say, the whole experience from setting up the appointment (they ask of you detailed questions but it's important that they get as precise as possible to prevent mishaps) to the day of installation. I offered to show them YouTube guides, because many people noted that this particular AC is a tough install. They told me it was ok, and that they can handle it. They definitely did, as it only took 30 - 40 minutes mins. The installers are very professional and nice to work with read more

I had reached out to this company for a quote for AC cleaning, they were very responsive, detailed and fair regarding the pricing. What impressed me even more was that there was a recall for the brand of AC that I was requesting service for, and they alerted me to it for a free repair or compensation. They are a very honest company and I would refer them to anyone who needs AC related services. read more

No complaints. Came within the promised time period (though at the very end of it), finished the job in less than 10 minutes, and only cost $85. The technician was friendly and efficient. I recommend following up by email after submitting a quote request on their website. read more

Everything is very good with my install of two new LG ACs in a pre-war Manhattan apartment. Sean's work is excellent, and Dave kept up a detailed correspondence in advance to be certain we had as much detail as we could in advance. BONUS: Good value TIP: The more detail you can provide to Dave during the booking process, including photos, the less likely your install will be different from your expectations and the estimate. read more

Dave and his team work wonders and nobody can beat there immediate work response and how quick they accommodated my work schedule. A++ I recommend KEEPCOOLNYC if you want your Air conditioner installed Properly and secure. They even install Midea U shape AC and Slide out units. read more

I scheduled an appointment last Wednesday for the following Monday. The website lists window units as $100 but they quoted me $150 for install. I said ok. Only hours before the appointment, Sean sent a text that he needs to either charge more or reschedule because he won't be in the area today. How unprofessional! My family rearranged our schedules to make sure we'd be there for the appointment. Don't rely on these unprofessionals in a heat wave. They'll shake you down for more money! read more

Fast response and exceptional service! I submitted a request for an AC installation on a Friday night and Sean was able to come the next day between 12-3pm. He called me when he was 30 minutes away and again when he arrived at the building. I was so impressed by how quick everything was. Sean was really knowledgeable about the unit and explained the process to me. He had no problem installing my AC and was able to remove the window safety guard. Everything came out to $200. It was worth every penny. read more

I wish there is a 6 star rating. The service I received from Keep Cool was beyond terrific both onsite and remote customer interaction. Questions are rapidly addressed (even after business hours) and scheduling was prompt. Documents (insurance forms) were executed swiftly. The awesome installer showed up exactly when he said he would. His work product was excellent. He was neat, tidy and very STRONG. Very little debris to deal with. This is a 6 star service for sure, and at least. I rarely write reviews. But, this is one I cannot miss. Keep Cool is a keeper for sure. Let's make it successful. read more

AC window installation was very well done. Price was much less than other companies in the area. The tech was professional and on time and finished in a timely manner. Responses were quick and easy to set up an appointment. COI was done within time frame. Don't wait until a heat wave to arrange your AC installation!

I had a top notch experience with Dave at Keep Cool. He replied to all my emails and messages very quickly, had very competitive pricing, and most importantly he did a fantastic job installing my ACs. I especially like that pricing and options are listed on their website, so everything is understood before I booked the job. I had a really ugly pre-existing install that he redid for me with plexiglass, and he replaced my broken old AC with a new one. He also fixed one of my safety bars so that the window can open (it was stuck closed before). Talk about going above and beyond, I couldnt be happier with the result! read more

Dave and his team provide excellent and comprehensive service at amazing prices. I reached out to several different AC installers for my window unit, but Dave and his team were hands down the best. Easy booking form, fast service (think the technician was in and out in 45 minutes or less!), and so many different options for installation (we opted for a security bar to allow us to keep the window open). If you're looking to install an AC unit, get in touch with Keep Cool. They're awesome! read more

Easy and quick. Joel was great at installing my AC unit and was very professional. Would highly recommend.

Dave was absolutely fantastic. He arrived right on time and took care of our two A/C units quickly and efficiently. We're really grateful for the positive, professional and inexpensive experience and we're happy to recommend his services to anyone who might need them. read more

Keep Cool did a great job installing two A/C units. One was standard in the bottom of the window with a bracket...took them 10 minutes. The other was a top window installation...took 40 min or so...it looks great and works perfectly. Would recommend! They did show up slightly late but its busy season and they apologized so nothing that impacts the review since the benefit was so worth it. read more

Thank you David for arranging a last minute AC installation! Your guy was awesome and even waited for us to come home in pouring rain. He installed both units incredibly quickly and I can tell did a great job. I definately recommend!!! read more

I'm extremely impressed. Dave happily accommodated my last-minute, 93 degree temps-inspired request to bump my installation up a day, and Joel, the technician, was on-time, professional, friendly and extremely competent. I sprung for the plexiglass and I highly suggest you all do as well. After years of duct-taping hideous accordion folds, the clear plexiglass installation and rock-solid bracket look like pure sorcery. Can't recommend them enough, I'll be a loyal customer for as long as I live in NYC. read more

I engaged Keep Cool NYC to remove an old Window AC unit and replace it with a new one of identical size / brand. They were responsive and quickly provided a quote. It is a large unit and is placed at the top of a window and so I thought the cost of $250 for the installation (+ $30 for COI) was reasonable. The installer also suggested contacting 311 to remove the old Window AC unit which was appreciated, even though I ended up paying for a professional junk remover. Communication ahead of the installation was clear / prompt and the team quickly removed the old Window AC unit and replaced it with the new unit. While the speed was appreciated, the team could have moved more slowly but more carefully. Following the installation, I noticed that a cabinet near the window was kicked in, with the cabinet appearing to have been kicked either when the old unit was being carried down the ladder or when the new unit was being carried up the ladder. When I mentioned the damage the next morning to the Keep Cool NYC team, I received a conflicting response. The installer stated that he believed me while simultaneously putting forward several implausible theories that I (not the Keep Cool NYC team) had damaged the cabinet. Given that I wasn't asking for Keep Cool to fix the damage to the cabinet or to compensate me, it seemed odd that the response was to deflect. I ended up having to pay a carpenter ~$150 to fix the cabinet. The old Window AC unit, which was heavy and had sharp metal edges, was also placed directly onto the wood parquet floors of my apartment, even though it could have easily been placed on towels that were nearby (on the floor) or onto cardboard from the box that the new Window AC unit had been delivered in. The wooden floor was scratched under the Window AC unit and I will have to get it sanded back and polished at some point in the future. While I'm happy to have my new Window AC unit installed, it is disappointing that my apartment was damaged in the process. Keep Cool NYC has many positive reviews and I had assumed everything would go smoothly. I wish that I had been watching the entire installation more closely and could have asked for the old Window AC unit to be placed on towels / cardboard. My experience may be an aberration but I would recommend being remaining close during the installation process, if you can. read more

Amazing. Will, hire again if I need it. KCNYC did two AC units for us and one with plexiglass. Both turned out better than I expected. Thanks a bunch from Crown Heights! read more

Dave and his team provide a great service. Particularly helpful that they can provide a COI as my building requires it. They are responsive, on time, honest and do a really great job. Definitely recommend them! read more

Really wanted to hire this firm based on the stellar reviews, but the online booking process is ONEROUS. At least two photos of the window required, several different measurements required, along with a litany of of questions. I've filled out background check questionnaires which were less intrusive. If I knew all those answers, I'd be installing the darn air conditioner myself. I can't. This was ridiculous. read more
