EXCELLENT Based on 46 reviews Posted on Google Michael Di Fonzo20 May 2026Trustindex verifies that the original source of the review is Google. Ali and his team were amazing to deal with. I was looking to replace my old A/C unit and Ali provided a few options. I had many questions and he took the time to answer all of them which helped us make an informed decision. Not only that, his team was able to work around my renovation schedule to replace the existing line and return another day to complete the installation. This allowed a smooth process end to end. Ali and his team take great pride in their work and the quality shows. They ensure their clients are taken care of and satisfied. Communication was great and they were always on schedule, punctual and prices were very fair. We're so happy that we went with Kobist Air. Highly recommended!Posted on Google Amir Zand17 April 2026Trustindex verifies that the original source of the review is Google. The Michael Jordan of HVAC. I've been struggling with a 3 year old GoodMan 2-Stage furnace (with 10 yr warranty) installed poorly by another co. & have had nothing but problem since the install (parts, unit going on/off, unit not working, no heat, emergency gas line cut-offs with Enbridge emergency gas cutoffs & fire trucks and all!!! So this winter began & the unit was kind of working, then in February when it got extremely cold the unit completely died. I called in 3 other companies and they had NO clue what they were doing, none of them had any tools to properly test & diagnose the issue and I think experience was a factor as well; they all left me with no heat in -20 degree celcius weather for days. As I was getting very frustrated, I opened up my Instagram for a break & I see an add for KobistAir, I called them directly from the ad & Ali answered. He was very responsive & explained he was out of town for a commercial job but will send his partner Joe same day to look at it. Joe called me and he was at my home within 2 hours. I explained the background and all the messing around and multiple years of problems with this new unit and he went at it. Got Goodman on the phone & followed their steps after I explained to Goodman what I've been through. He tested the crap out of everything & filled in multiple sheets that Goodman requested. He also ran out and grabbed some warranty parts and replaced them as well. Long & short of it is, these guys know what they are doing, they have the right tools and they are very nice people. I am happy I finally found a HVAC co. that knows what they are doing instead of doing dangerous and unqualified work and overcharging. I highly recommend their services and my recommendations do not come lightly!Posted on Google Neide Terrell4 April 2026Trustindex verifies that the original source of the review is Google. I had the opportunity to experience the exceptional service of the KobistAir team this past weekend when our 36 year old furnace finally gave out. I spoke with Ali, the owner, on Saturday morning, and within a couple of hours his partner Joe came over to give us their assessment. Two days later, we had a brand new Lennox, high-efficiency furnace and programmable thermostat installed at a very reasonable price. I can't say enough about the quality of this company's customer service; from the first phone call, to a follow-up video call a few days later when I needed help restarting the programmable thermostat, which I'd inadvertently messed up, their care was evident. If you are looking for an HVAC company that goes out of their way for you; values integrity; provides quality workmanship, and is dependable, then I would highly recommend KobistAir. Thank you so much!Posted on Google Nadine7 February 2026Trustindex verifies that the original source of the review is Google. Ali and team are the best! Very fast response and visit for my issue. Installed my new air conditioner in the spring and it’s working beautifully and does my maintenance. Very reasonable and professional and great to deal deal with with. I highly recommend.Posted on Google Mike Yuan5 February 2026Trustindex verifies that the original source of the review is Google. Our old rooftop furnace stopped working in the middle of winter, and we needed a replacement. Ali showed up the same day we made a call and continued to make himself available to address questions, concerns and offer competitive pricing. Most importantly his team was able to line up a replacement and service within one of the coldest winter weeks. If this review speaks to you, give them a callPosted on Google Odysseas28 December 2025Trustindex verifies that the original source of the review is Google. I recently had to replace my 18 year old furnace with a new one and Kobist Air team made it a smooth as it can be process. They answered all my questions on different models and brands and provided competitive pricing as well as a fast and smooth installation experience. As a smaller size contractor they take pride on their work delivering a high standard service without any uneccesary sale nonsense. Would highly recommend them.Posted on Google Elena Mitnik28 November 2025Trustindex verifies that the original source of the review is Google. I recently had my furnace installed and I’m extremely happy with the entire experience. Ali and his team was professional, respectful, and really took their time to make sure everything was done properly. They explained what they were doing, cleaned up after themselves, and made the whole process stress-free. My home is already so much more comfortable. Highly recommend!Posted on Google nanda kumar8 November 2025Trustindex verifies that the original source of the review is Google. I am writing to highly recommend Kobist Air for their exceptional service. They recently replaced the rooftop furnace system at my restaurant, and I am extremely satisfied with the entire experience. From start to finish, Ali was a pleasure to work with. The team arrived early in the morning and completed the installation by 9:30 AM, ensuring no disturbance to our customers. Their efficiency and professionalism were greatly appreciated.Posted on Google Christine Regalado6 November 2025Trustindex verifies that the original source of the review is Google. Ali and team are very professional and efficient. They replaced my old furnace and air conditioner in one day taking care to put down drop sheets to ensure my floor and carpets were kept clean. They also cleaned up the area where they worked leaving absolutely no mess which I really appreciated! I was very impressed by Ali's communication, punctuality and everything he said he would do he did in a timely fashion. I will definitely use Kobist yearly to flush my tankless washer which he has done since installed and any other HVAC and Air Conditioning requirements without any hesitation! A well deserved and earned 5/5 star rating! Thank you Ali and Kobist team! Nov.5/25Posted on Google Houri Zarrin24 October 2025Trustindex verifies that the original source of the review is Google.
