    The team showed up on time, being highly professional and efficient. They completed 7 installations quickly and left everything spotless. Breaking through concrete walls was no issue for them - they made it look effortless. The installers consulted with me to determine the best placement for each unit, providing their expertise when needed. I'm extremely pleased with the product and the overall service provided.

    This technician exceeded expectations by showing up right on time at 10:30 AM and staying until well past 2:00 PM, taking the time to meticulously inspect every nook and cranny of our home. He thoroughly checked and cleaned each unit, used a thermal gun to evaluate our windows, and carefully reviewed all the upgrades we've made to improve insulation.

    What really impressed us was his patience and expertise. He took the time to explain how the remote control worked in detail, helping us grasp how to use it effectively. He also helped us identify areas for improvement and provided valuable insights on what would be needed to boost performance. His assistance in providing clear feedback to our sister company was instrumental, especially since our home was still reading in the 20s-30s even with the units set to 80.

    The technician's professionalism, thoroughness, and genuine interest in finding solutions made a lasting impression. He went above and beyond to ensure we had a positive experience. We're grateful for his help in making our home warmer and more enjoyable to spend time in.

    I had a great experience overall with this company, thanks to my sales rep, who was extremely knowledgeable compared to others I've dealt with. What set them apart was their expertise on NYSERDA programs - they helped me qualify for a free heat pump water heater and insulation, which saved me a significant amount of money. Unlike other companies, they didn't try to upsell me on the same expensive options. The installation team arrived on time and completed the 6 mini split work in just one day. I'm grateful to Rasean and Karen for making the process smooth and stress-free.

    My experience with Always On was top-notch from start to finish. The short wait time between consultation and installation was impressive, and the finished product looked great. The cleanup afterwards was also spotless.

    However, my interaction with the installers left a bit to be desired. None of them spoke English fluently, which made communication a real challenge. I understand that language barriers can happen, but it's frustrating when you're trying to ensure things are done right or have questions during the installation process.

    Using Google Translate to communicate in Chinese wasn't ideal, and it was tough to convey my needs or concerns. Despite this issue, I still highly recommend Always On for any future HVAC needs. They clearly do good work, and with a little improvement on language support, they could be perfect.

    This HVAC company delivered from start to finish. Booking was hassle-free, and they kept me informed throughout. The technicians arrived on time and did their job efficiently. They quickly identified the problem, presented options without upselling, and had everything up and running.

    The work was top-notch, and they left the space tidier than when they started. It's a rare find to have a company that balances expertise with genuine customer care. These guys got it right.

    I'm thoroughly satisfied with their service and will definitely choose them again.

    The technician arrived promptly to fix a minor issue with the water heater, which they resolved efficiently. I'm grateful for Karen's professionalism and prompt response during the installation process – she's extremely capable and always answered my calls promptly. A perfect experience despite the initial hiccup.

    I recently had a great experience with this company. I called them to schedule an appointment, and they were able to come out to my house promptly. Thomas Morales showed up, was very friendly and professional, and took the time to explain everything in detail. I'm extremely satisfied with the service and the results. The job was completed quickly, which was a bonus. Overall, I'm very grateful for their work and highly recommend them - you won't be disappointed!

    I bought three split units with two condensers, one in each of my kitchen, master bedroom, and spare bedroom, following the salesman Matt's recommendation that I only need one in the bathroom since the air would circulate naturally. However, this hasn't been the case - my bathroom is usually quite chilly, often ranging from 52-54 degrees, so I ended up purchasing electric heaters to supplement the heat.

    The units are not effective for heating when outside temperatures drop below 30 degrees. During a particularly harsh period in January and February 2026 in Calverton, NY, where I had 60 days of below-freezing weather, my home was consistently cold. My electricity bill tripled over the course of one month.

    These units are not as energy-efficient as advertised. They run continuously, but I don't feel warm inside my house - instead, sitting near a unit makes you feel the air blowing on you and it feels cold. As a result, they've eliminated my oil burner, leaving me without a backup system, which forced me to purchase additional electric heaters.

    This decision has been a disaster. I was misled by the salesman, and now I'm considering seeking legal action for a refund and possibly filing a class-action lawsuit against ALWAYSON HVAC and PSEG, who are profiting from customers like me being stuck with electricity bills.

    Two split heat pumps were installed efficiently and cleanly by these professionals. The job was done at a competitive rate, including city incentives. Customer service from Feng L is excellent - he's responsive and strives to resolve issues promptly, making the experience hassle-free.

    We're extremely dissatisfied with our experience with Always On from start to finish, especially after the initial installation.

    Things took a turn for the worse shortly after the install, when multiple units stopped working. We had to repeatedly contact the company to get someone to come out, and it wasn't until then that they agreed to send a technician. When he arrived, it turned out there was a leak - a problem that shouldn't have happened after a professional job.

    Since then, our units have been unreliable and we've had a hard time getting help. Customer support has been unresponsive and unhelpful. To make matters worse, we were told we'd need to pay cash upfront for a technician visit, despite the issues clearly being their fault.

    This company seems completely unconcerned with customer satisfaction or standing behind its service. If I knew how they operated after installation, I wouldn't have chosen Always On in the first place. We strongly advise others to think twice before using this company.

    I'm extremely satisfied with the recent heating and cooling installation I had done. From start to finish, the process was hassle-free and professional. The team showed up on time, explained everything clearly, and worked efficiently while keeping the area tidy.

    The installation was spotless, and the system is working flawlessly - it's surprisingly quiet, powerful, and already making a noticeable difference in my comfort level. What impressed me most was their focus on detail and willingness to answer all my questions without rushing. The pricing was fair and transparent, with no surprises.

    If you're looking for an HVAC company that delivers exceptional workmanship and top-notch customer service, I highly recommend this one.

    Always is the go-to choice for reliable and efficient service. I did my homework before hiring them, and multiple quotes later, they're still top-notch. Their customer-centric approach shines through in their excellent customer service. I highly recommend them - no need to look elsewhere. A huge thanks to Resean, their sales agent, who was incredibly helpful and knowledgeable. He's always welcoming on the phone, and my kids even call him "Uncle Resean"! That's true customer service. His kindness has earned a special place in our hearts.

    Here's a rewritten version of the review:

    We got excellent installation work done, but our experience was marred by communication issues. The mini splits are working great, thanks to Rasean who handled everything professionally and responded promptly to our questions.

    However, none of the technicians spoke English fluently, making it hard for us to understand their explanations or resolve any issues we had. They left the boiler room in a mess and couldn't finish the wiring or explain what was wrong with our backup heat system - see photos below.

    I reached out to Sam about this issue, asking when they would return to fix the problem. I'm still waiting for an update.

    The technicians arrived quickly and completed the job swiftly. Pricing was reasonable. Installation went smoothly, but communication with the team, who spoke limited English, caused some difficulties. Despite this, we're overall pleased with the new heating and cooling system.

    The service providers did an excellent job, demonstrating thoughtfulness by removing their shoes before entering the property. Their punctuality and enthusiasm were evident throughout the process. The work itself exceeded expectations, with a high level of quality that left no room for improvement. They also showed attention to detail by cleaning up thoroughly after completion, making it clear there's nothing negative to report about their performance.

    I recently got a split air unit installed on November 13th, but two weeks later I'm extremely dissatisfied with the work done. I'm willing to cut some slack when things don't go as planned, but what really gets my goat is the lack of communication from this company.

    The installers showed up 30 minutes early, which was a nice surprise, but it turned out to be more of a hassle than a help. They took hours to complete one unit and I had to track down the installer myself just to get an update on what they were doing. To make matters worse, there was a significant language barrier that made it impossible for me to get any information from them directly.

    I had to call Always On HVAC multiple times to get someone who could communicate with me, and even then, it took forever to get a response from their boss. Having someone on site to explain what's going on would have been a huge help - I'm talking 100 hours of waiting around wouldn't have killed me if only someone had taken the time to keep me in the loop.

    After the installation, it was clear that the language barrier had also caused a problem with explaining how to use the system. The installers left the manual behind and had to come back to retrieve it after I asked them to. And just last week, I noticed an error message on my outdoor unit that's still not been fixed.

    To make matters even worse, the installers were sloppy in their work. They left exposed wires in the electrical panel and tried to cover them up with pipe insulation - which ultimately had to be corrected. You can see the photos attached to this review for yourself. Overall, my experience has been a disaster and I would not recommend Always On HVAC to anyone.

    I've dealt with Always on HVAC three times before, and unfortunately, my previous experiences weren't positive. But this time around, sales representative Rasean impressed me - he followed through on his promises. We got the work done in just two visits after initial contact with him. The installation team was tidy and efficient; everything went smoothly overall.

    Our technician arrived right on time, providing advance notice before entering our home. The footwear he wore kept him from tracking in dirt and snow onto the floor. During the service, he took care to avoid damaging any surfaces or components.

    Led was attentive to detail, asking questions and offering suggestions for improving efficiency and reducing energy consumption. He demonstrated a thorough understanding of his work and took the time to answer all our queries. His professionalism and courteous demeanor made this experience very positive.

    I had a fantastic experience with Viking. They exceeded expectations in terms of professionalism and customer service. The technician arrived promptly and took the time to explain everything clearly, ensuring I understood the issue and my options. Pricing was transparent and upfront, which is a rare find. Viking's honesty and reliability made them stand out – I'll definitely be calling on them again.

    We were lucky to have Max step in when our previous HVAC contractor dropped the ball on a job left unfinished. From start to finish, his service was top-notch. He quickly took stock of the situation and broke it down in simple terms - what needed fixing, what didn't, and what he'd charge for it.

    Throughout the process, Max was approachable, transparent, and communicative. He took the time to walk us through the work involved, helping a non-techy homeowner like me understand the system. The result? A hassle-free resolution of our outstanding issues that left us feeling confident in the quality of the work.

    We'll be back for future maintenance or installs, no question. If you're in Brooklyn or surrounding areas with split HVAC systems or need help with existing setups, Max is your guy - highly recommended!
