Perfect experience. Straight to business, installed 2 splits in less than 2 hours and left no mess behind. Polite, courteous. Just the perfect transaction that you'd want with a project like this. Also, very knowledgeable. They noticed an issue with the original plan, pointed out some problems with the wall and suggested a much safer alternative. So far everything is working great and my 2-story house is perfectly cool in this hot weather. read more

We had a great experience with Optimize Air. Andre got our PTAC unit blowing cold air again and we are so grateful.

Needed an inspection of boiler for insurance company. Booked an appointment, easy. Guy came when he said he would, sent text earlier to set expectations. Pleasant, explained things in easy to understand manner, addressed a minor issue (no extra cost) and got thing done in a professional manner. Pricing for the inspection was fair and clear. Other companies wanted to layer in other services on top of the inspection (bait switch). I only wanted inspection and it was what I got for a reasonable fair pricing. If I have any boiler issues, these guys will get my business. They are going into my rolodex (look it up youngsters). read more

They wanted $400 to install a $550 a/c through-the-wall unit. This seems excessive by any measure. Update 2026/08/24: That is correct, I never hired them for $400. I had three different offers from their competitors here on Yelp, ranging between $140 to $200 for the entire installation. I accepted one of those offers. I did not hire them because asking $400 for 30 minutes of work is beyond ridiculous. That's an effective $800/hour rate. read more

Highly recommend! Great service, courteous and reasonable cost! Andrei fixed my unfixable PTAC!

George was fast in his response when scheduling a service and Andrei performed boiler maintenance for us after we noticed that the top floor of our townhouse wasn't heating. He helped check our system and addressed the issue quickly. He also identified some additional things we could address but didn't pressure us in any way. Overall, my experience with Andrei was excellent, the price was very fair and would definitely use Optimize Air for future needs. read more

Great service! Professional install!came on time and did a great job! Definitely Will hire for future installs. Thanks paul! read more

I hired Optimize Air to replace a through wall AC unit in my bedroom and portable AC unit in my living room. They were incredibly responsive and we scheduled a date very quickly. They quoted me a great price for both jobs. They hauled away my old unit and everything was done in less than an hour. I would use them again. read more

I have used Optimize for home and business for years. Extremely knowledgeable and professional. They installed large and small systems for me, mostly recently they swapped out a compressor as an emergency. Excellent people. read more

Their technician showed up on time, for diagnostic visit for my PTAC refrigerant gas leak I've been smelling and tested positive twice with my two different, high quality refrigerant las leak detectors I bought, on different times. Andrei K. opened the unit, and after a while told me he doesn't see a leak, and his company could seal the joint of the slightly eroded metal pipe connection by metal molding + replacing another piece of metal connection. His manager will send me an email in a couple of days, the estimate of that costs, with written summary of this diagnostic visit, since Andrei's English was often hard to understand since it is his second language, I asked. That was one week ago, I've called Optimize Air several times, no one picked up the phone unlike previous times. So, I emailed them, No reply at all! Would they act like this if they haven't collected the full $200 for this visit as Andrei left my place, with a promise of a report and the estimate in a couple of days? Unethical company, I feel short changed. How did they get All Five stars customer reviews?? Be aware! read more

We needed to fix our HVAC unit and we found them. They came on time which is pretty rare in the city and repaired our unit. Alex, the person who came explained how our unit had a problem and how to maintain the unit. We have now a working HVAC and so happy!! Thank you optimize air!! read more

They were great and checked everything thoroughly to find the leak. Most of all they never tried to charge us for things we didn't need.

Good service, helpful and quick response time. Organized and clear with explaining issues, happy with results. Thank you.

We had separate LG HVAC units that were improperly wired so that we kept getting a CH53 code. We initially started w another HVAC servicer that came in and tried to rewire everything by cutting open the walls and taking the wires out. They left with the job horribly uncompleted and thank goodness we found Optimize Air who sent Alex to help us reset everything correctly. Of course, without a question, we used Optimize Air again when we heard a whirling coming from another HVAC unit and they sent Andre who correctly diagnosed it as a broken motor and was able to get the replacement part and install it correctly. They were all refreshingly responsive, professional and honest. They'll be my go to for (unfortunately) the many HVAC issues in my apt! read more

The team from Optimize were professional, responsive, and most importantly efficient. They came right on time, assessed the problem, and provided several solutions. I have a brand new system with very spotty installation. The guys at optimize were honest and gave two solutions. They fixed the problem within an hour and left no mess. I hope that I don't have to call anyone again but if I do, it will be these guys. I have LG ductless units and they were the only ones who could service the units. read more

Exceptional team - Siarhei and his crew helped us convert old PTAC units into a mini split system in our condo unit. They offered the most reasonable, transparent pricing among the vendors we'd spec'd out. Every member of the team was friendly and easy-going, and most importantly, knowledgeable, fast and efficient in their work. Our place was properly prepped to protect from dust and damage and was thoroughly tidied up each day - which made living in the condo still possible during the installment period. Could not recommend the team enough! read more

Great -- highly recommend! Optimize installed a 5-zone mini-split system in our Brooklyn brownstone. Communication was great, they were on time, and on budget. Projects of this scale always feel daunting, so it's a comfort having a team you can trust. read more

Andrei K. was absolutely fantastic. He responded to my messages to solicit a quote, quoted a fair price and rate structure, and showed up exactly when he said he would. He identified a flaw in my installation which was causing my leak, and diligently fixed it. He took the time to show and explain to me what was wrong. I found him honest, professional, and knowledgeable about my Mistubishi mini-split ductless HVAC system. Highly recommend. read more

They were very responsive from the get go, and even accommodated a last minute switch because I needed to schedule something else before they came in. I was also able to get a COI from them, which my building needed. Andrei, the person who came, looked at my hvac, explained to me how it worked, and proceeded to fix the issue very quickly. He also checked the other units for good measure. I am very pleased with the service. read more

The team was really helpful from start to finish. We needed our AC cleaned (mold build up) and the tech was really helpful and kind. We have a split AC and so it needed to be taken down to the street but they handled everything with great care. For the price, it went above and beyond and we are now breathing in clean air. Super grateful to the whole team and would recommend! read more

This is a review for annual boiler maintenance. It was easy to get a quote from George through Yelp, the quote was in line with other quotes we received, and they were available within a week.

Andrei's team was courteous and thorough during their visit, patiently answering questions, and waiting til our heat turned on to make sure everything checked out. Will continue to use them! read more

We've had 4 Mini Split units installed by Optimize over the past two years. Two were replacement and two were new installations. Both times the cost was highly competitive and the work was done efficiently and on time. They kept our place very tidy while working, consulted with us when there were questions related to the new installs and were very pleasant to work with. I plan to contact them for servicing as needed in the future and highly recommend Siarhei and his crew! read more

Siarhei responded quickly to all communication, provided the only estimate with a cost breakdown, and scheduled the work for the following week. The installers were great: friendly, competent, neat, and happy to accommodate. I'd certainly use Optimize Air again. read more

We love the 3-unit Mitsubishi ductless air conditioning unit they installed for us. Price was thousands less than quotes we had received over 2 years of research. The units look great and work great. They cleaned up thoroughly after the job. Their recommendation to cover the outer wires was terrific. Got one of these: 12,000 BTU 23.1 SEER MITSUBISHI DUCTLESS WALL MOUNTED AIR HANDLER SKU: MSZ-GL12NA-U1 and three of these: 9,000 BTU 24.6 SEER MITSUBISHI DUCTLESS WALL MOUNTED AIR HANDLER SKU: MSZ-GL09NA-U1 Even better, they recommended a contractor to use for my downstairs renovation and we'll be engaging them soon. I look forward to recommending these guys to my friends and highly recommend them here on Yelp. read more
