When our heat stopped working a few days ago we contacted JNT mechanical based on a recommendation from a friend of ours that uses them frequently. We called them at 8pm, expecting to leave a message and hear back from them the next day since it was so late in the day, however, we were pleasantly surprised when John answered right away and said he would be happy to come out that night. He was at our house within an hour of us calling and had our heat up and running in 2 hours. The most amazing part is that I had geared myself up for paying through the nose since it was so late at night, but he didn't charge us any kind of night fee/ emergency fee. With his labor and the part, we paid less than half of what we were expecting to pay!!We have a 16 year old furnace, that we will most likely have to replace soon, but instead of John trying to sell us in replacing, he said he could fix the part and that would buy us some time to save money to replace the furnace at a later date. Needless to say, we are going to call John in the fall to do the replacement. He is such an honest guy and we can't recommend him enough!! read more

We have used JNT many times in the past and had the pleasure of working with Alex and Peter again yesterday- a Sunday. Our heat stopped working very suddenly last night. I'm not sure what time it stopped running, but when I got up at 12 to feed my daughter, the thermostat was reading 63 degrees. I called right then bc it was freezing and only getting colder (my baby's nose was ice cold). I asked Alex if they could come out first thing this morning and he said they were pretty busy in the morning already but insisted I didn't have to wait until the afternoon and offered to come fix it right then. He arrived in under 30 mins, fully masked, wearing shoe booties, and gloves. He had us back in business in about 20 mins and insisted we only pay him for the part and no labor since he was done so quickly. This kind of service is nearly nonexistent these days, people are constantly trying to pick your pockets for everything they can, this is not how JNT Mechanical does business and I couldn't be more grateful to these honest, kind, hardworking guys. Thanks again!! read more

10 Stars Johnny is Honest, Honest, Honest and his quality of work is excellent. Let me tell you about my experience. I came home late last night from a vacation and could not wait to take a warm shower. I ended up taking an ice cold shower do to my water heater not working. I tried to relight the pilot for about an hour and gave up realizing that it was time for a new one. The following afternoon, I called JNT and explained my situation and also mentioned that my hot water heater was in a terribly tight spot and we might need to cut the drywall out. Johnny met me at my house in exactly one hour after we spoke with a brand new hot water heater and spent the next 5 hours removing the old one, the drywall and installing the new one. I am still in shock as to how smoothly everything went. Please do not waste your time calling anyone else for HVAC. Johnny and JNT are life savers. Thank you one million times for your professional and excellent service. read more

I had another company come out to check my AC which was not working, they didn't even look at it for five minutes before they told me that I needed to replace it. They gave me a price on the spot for over $11,000. The speed with which they diagnosed that I needed a new AC left me uneasy so decided to get a second opinion. My sister is in a Facebook group of Mom's and she gave me the most recommended referral for HVAC which was JNT mechanical services. Peter came the same day and went over the AC very carefully and found that there was a small part that needed repairing. if the people at JNT had told me that I needed to replace my AC, I would've done it but Peter's honesty and attention to detail saved me from spending my hard earned money on something I didn't need. It's shocking how easily people will lie to you to make money or the tech of the first company had no idea what he was doing. Either way, it's unacceptable.JNT has gained a customer for life. read more

From the moment I spoke to John over the phone I sensed his honesty and sincerity. John, came to my house to provide an estimate on my malfunctioning AC unit on his day off, Sunday. John, provided a very competitive price against 3 other companies, and John's work and service was excellent. I was also impressed that he didn't charge me extra labor when more work had to be done. All he ask for was additional payment for the extra materials used. John, has come to my house two more times since and, did a fantastic job. I highly recommend John. Small businesses are always harder to trust than the larger companies, but, you can trust that john will provide you honest and sound work. read more

JNT Mechanical Services is the absolute best HVAC company I have dealt with. My neighbour recommended them and I'm so happy I listened to her recommendation.. I had four seasons,, ABT, All temp, and JNT mechanical services I'll come out to give me estimates for a new AC. I won't go any details but I will say that the highest was 17,000 for one AC and JNT was the lowest by over $8000. How is that even possible? Big Pharma has got nothing on these HVAC companies and their profit margins it should be absolutely illegal. Anyways, JNT came they were responsive kind clean and did a wonderful job. I couldn't be any happier. I am telling everyone I know about them. read more

John came out of his way to install a lighting fixture a friend of mine wasn't able to hook up correctly. While he was here, I asked him to look at my furnace, which was on the fritz. He actually left to go get the appropriate part. I'm a woman who owns my own condo, and I've no idea about things like this; a lot of companies can take advantage of the situation by charging me more because they can. At the end of the day, everything was fixed at a very reasonable price. I would recommend JNT to anyone who was in my situation, and I will only use them in the future. Thanks John!!!!! read more

JNT was amazing to work with. Our heat went out on a Sunday morning and we frantically called JNT. We were pretty sure we knew what was wrong and told them. Before having us pay for them to come out they suggested we try a quick troubleshooting method that could fix the issue on its own. They easily could have skipped this and just come out and charged us for it--I so appreciate their attempt to save us money. When that did not work they were here within an hour and got everything up and running quickly. John could not have been kinder or easier to work with! read more

I could not have had a better experience!!! John is not only an amazing technician but a great guy. On a freezing night, he came the same day to inspect our furnace. He came out the very next morning to fix it and got our home nice and warm again. John took the time to show me exactly what the problems were and the price was better than I planned for. John made our family feel like WE were his priority. Thank you John! Please call JNT for your HVAC needs. You'll get an honest, experienced tech who will treat you MORE than fair. read more

JNT was such a pleasure to work with! My heat stopped working late at night during the snow storm and I have kids, so I couldn't wait until the morning to get it fixed.... I called around and JNT mechanical was the only company willing to come and figure out what was wrong that night. Johnny had the part I needed in stock on his truck and got my heat working within an hour! From now on any issues/maintenance my HVAC system needs, Johnny is the first and only person I am going to call! Thanks again JNT, you guys are awesome!!! read more

I am not a 'savvy' appliance person, that's for sure. So, when my AC went out on the first hot day of the summer, I wasn't sure who to call. I found John at JNT right here on Yelp and let me say - he was FABUOUS! He actually was able to come see me the same day. He diagnosed a problem that had been created by the person who installed my new furnace last winter and offered numerous solutions to fit my budget. He was extremely helpful and timely. I would highly recommend him to anyone!! read more

We called a bunch of companies to come fix our heat on one of the coldest nights, and John at JNT was the only one who answered on the first ring. He sent out a technician named Peter who arrived on time. He quickly found the problem and just so happened to have the part on his truck which was a big relief. He even wore shoe covers as to not track snow into the house which my mom was thrilled about! We will definitely use them again for any future problems. read more

JNT has been my go-to for any electrical work in my family's 3-flat for the last 15 years. They are clearly experts in their field, and the quality of their work is always exceptional. A few years back, we fully renovated one of our units, and JNT did all of the electrical work. Not only were their prices lower than any of their competitors in the area, but they finished their work way ahead of deadline! Great work ethic and quality work for a good price. read more

Couldn't have had a better experience. From the ease of setting up an appointment with Rachel to the technician. Peter came out just for a yearly furnace inspection. He was very thorough and took his time to inspect my unit. Didn't try to push any unnecessary repairs or upgrades which was a great change to other companies I had used. Definitely will use again in the future. read more

My family and I have used this company for several years. The great prices and service is on thing. Being able to handle jobs ranging from my moms 1920s bungalow, my sisters large apartment complex is unbelievable. They even fixed things at a brand new high rise in river north were I own my condo. Bottom line! Most honest contractors in all of chicago. read more

This company, its owner and the employees are top notch!! They extended a hefty (over 50%) simply because I was widowed the previous year and had been absolutely swindled by another "big" company. I recommend them to everyone and will personally never go elsewhere! THANK YOU JNT! You restored my faith that there are still some decent people around. read more

John just installed my AC unit and not only was he professional and honest but gave me a great price. My friend recommended him after i got a quote that was ridiculous from another provider. I am glad i called him and will definitely be using him for maintenance and future heating and air needs. read more

We were very happy with JNT Mechanical Services. We lost heat late on a Friday night and John was here an hour later. We then needed to call our gas provider and John came back early Saturday morning to complete the job. They provide great service at a great price. read more

Fast, professional and quality work. We had our old electric panel and old water heater replaced before we moved into our new home. JNT did a fantastic job and even hung some of our light fixtures. Highly recommend! read more
