We had a Generac generator installed that runs on propane. The need to connect the propane tank to the generator required a preliminary setup  that had to be inspected by the town for leaks and for code compliance. It passed with flying colors. Just now, John Norlander - company owner - came on a Sunday to complete the connection. He explained that the generator installer needed the propane hookup done ASAP so he could finish the job and get it ready for final inspection this week. Big John (his preferred name) contacted us to see if it was OK to come on a Sunday (no extra cost) to support the generator installer. Of course, we said yes! I just went over the job with him - he did a remarkable job - professional and esthetically beautiful. This is a professional company that I recommend if you want the job done right ! read more

They tried installing a smart thermostat ~6 months ago, and broke the connection with the AC. After a few visits with HVAC technicians and electricians, it seems like they gave up trying to fix it, and just ghosted us. Still no working AC, and now we have to call in another company to clean up their mess. I think the next time we'll see them will be in small claims court. read more

Buyer beware. I've been trying for months to get this company to fix a problem caused by their incorrect installation of an Ecobee thermostat (after we specifically asked them to only install it if it was an easy switch from our Honeywell). The installation left our AC unable to communicate with the thermostat, and we had to sleep with the windows open for several days in late fall. After I followed up several times with the company, Peter returned and said an electrician was needed. When the electrician came (without Peter), he spent three hours at our house but couldn't figure out the problem. I then had to again repeatedly follow up with the company, and promises to schedule repairs were often ignored. Even the owner apologized and said it would be fixed, but no one would call or text me back. Today, months later, they told me for the very first time that this kind of issue can't be fixed until the weather warms up, and that they can only schedule a different electrician to do a walkthrough. During months of me following up, it was never communicated that this repair needed to wait until warm weather, and I had been told in the fall by Peter that they just needed to run a wire from upstairs furnace to basement wiring that connects to outdoor AC (all of which would be work done indoors). I waited to write this because I don't like leaving negative reviews, but this has been the worst customer service experience I've ever had with a company. read more

After having JNT do annual maintenance on my HVAC system the last several years, and seeing how professional, considerate and detail oriented they are, it was a no-brainer that they be the company I asked to replace my 25 year-old HVAC system. As a homeowner, word-of-mouth means everything when considering vendors. Hopefully you will take this positive review and contact JNT Mechanical if the need arises. PS: they'll never try to upsell you with any type of service contract. read more

Earlier this year, the condo was having issues and not turning on. The condo association recommended another service that charged $190/first hour and $170/hour after BUT they wouldn't be able to get there for another 2-3 days. I remembered my great experience with JNT and gave them a call. Not only were they more affordable but they were able to be there in 24 hours and fixed the issue. Definitely won't go anywhere else! read more

I have used JNT for maintenance on my furnace, always been very happy. Now I realize how truly good they are, though. My furnace died and the owner of the company himself arranged for me to get a new one at the height of a cold snap. Excellent, fast service, fair price, very patient with my 4,000 questions. Highly recommend, and I say that as someone with a ton of experience in the trades. read more

JNT is a beloved local company who is not only expert and responsive, but supportive of the communities in which they operate. As a 10-year customer (after trying several other companies), I have unshakeable confidence in them and have never been disappointed. They are responsive, honest, ethical and never try to upsell. A real gem! read more

I called John at JNT Mechanical based on all the positive reviews. The first time he came out, I needed him to help me light the pilot light on our water heater--which I couldn't for the life of me get to light again. We had been out of hot water for just under a day at that point. He came and lit it Friday morning and told me to give him a call if anything else happened. Well, the water never warmed up. Our water heater is 14 years old, so it was clear we needed to just replace it. I messaged John bright and early Saturday morning. I told him the model I wanted, and he said he would install it Monday morning. I guess I could have called around to ask if someone else could have come on the weekend, but I just didn't have it in me to try. On Monday morning (also known as Day Four of No Hot Water...), John showed up exactly when he said he was going to with the exact model of water heater I wanted. It took about two hours to install it, and holy smokes, our water is so much better than before. In hindsight, it's clear that the water heater had been struggling to fully heat water for at least a few months. I have nothing but good things to say about John. He was really nice, professional, efficient, and upfront about cost. It was a great experience all around. read more

Another happy customer here. We had an AC issue on labor day and service was prompt and professional and so kind! Would definitely recommend, and will use again. read more

Highly recommended. I started with JNT 6 years ago when managing the gut renovation of my house. I worked with John and Peter. As an architect, I can appreciate when a contractor is on the level. JNT has been maintaining the HVAC units since that time. Peter has performed all the work. He is professional and very pleasant when discussing options, costs and time. read more

After another company serviced my air conditioner, it stopped working. I called JNT who told me the unit was frozen over & they suspected a leak in the line. They turned it off so the ice could melt & they could return to inspect further. I prepared myself for the need to buy an entirely new AC unit. When JNT returned, they determined there was no leak in the line and "tightened a few screws that were probably left loose by the previous company." I haven't had any problems since. I was completely prepared to spend over $1000 on a new unit, and they didn't charge me anything for the return visit. I'll never call another HVAC company again. JNT is the best! read more

This is the second time Johnny has saved the day! The first was a few years back, doing electrical updating on my condo, and the second was today with my AC unit... up on the roof of a 4 story building. During the week I checked in to see if the expected 97 degrees today would have us rescheduling, but he assured me our appointment was still on. He was able to find a replacement unit for me at a reasonable price and got the job done quickly. So grateful to be writing this review in my (finally) air conditioned home. Contractors you can trust come few and far between, and I'm glad I know I can count on him for his expertise, reasonable prices, and kindness. read more

We first used JNT a few months ago when our furnace kept kicking off. They actually moved a previous appointment so Pete could attend to ours since we were without heat. Very, very thoughtful. Pete troubleshot and figured out the condensate pump had stopped and had backed up the pressure switch causing the issue within 5 min. I had had another company come out prior to JNT and they didn't troubleshoot. They just quoted me an outrageous amount for an part that was still good. JNT is absolutely the best with customer service AND system knowledge. They know their collective stuff! They are the best in the business! read more

After having 2 other companies come out and quote me $600-$900 for parts & labor, I decided to get a 3rd opinion. Peter came by and was able to get my furnace running in no time. He diagnosed the issue, fixed it and didn't try to sell me stuff I don't need. I plan to use JNT again for AC tune up. read more

Peter of JNT came at short notice to look at our noisy furnace--he performed a bunch of tests and was very thorough in seeking out & isolating the cause of the problem. To his great credit, was very patient and accommodating in answering all my questions and concerns. In the end, the problem was solved quite simply, and the charge for Peter's time and expertise was reasonable and proper. I wouldn't hesitate to use JNT again, and suggest that others consider trying them out--especially those with fears (or past experiences) of being 'stung' by one of the big hvac companies out there--those that always manage to find some part that needs replacing, and always for an enormously & shockingly inflated cost. My experience with JNT felt like finding a really good dentist or doctor--a weight off my mind. Phew. read more

Our heat when out on Saturday evening, so I called JNT early Sunday at 8 AM as the temp was down to 58 inside our home. Beforehand, I checked inside the furnace and it seemed that the igniter was not lighting the gas but I wasn't sure. JNT was at my door by 9:15 AM (on a Sunday, mind you) and spent the next 45 minutes diagnosing and replacing the igniter and fixing a stuck gas valve. It's 10 AM and we have heat again. Two hours from call to fix... Love it. Thanks to John from JNT! We'll probably need a new furnace before next winter (it's 15 yrs old) and JNT will be the first company we call. read more

I'm 9 months over due in writing this review. I found JNT through Yelp and decided to contact them because of all the positive reviews others had posted. I'm a naturally skeptical person when ALL the reviews are 5 stars, but after working with John, I can say that all the reviews are well deserved. I had sent him an e-mail through Yelp on a Sunday about installing 3 ceiling fixtures. Because it was Sunday, I didn't expect to get a response that day, but I got one within an hour. After exchanging a few messages, we set up an appt for John to come to my house to do the install. On the day of the appt, John was running late and contacted me proactively to let me know about the delay and asked if I wanted to wait or reschedule. I really wanted to get these lights done, so I said that I would wait. He and a young man (sorry, but I've now forgotten his name) came around 8PM and installed 3 somewhat complicated fixtures. It took them about an hour to get all 3 done. I'm sure they had a very long day by the time they got to my place, yet they were extremely upbeat, courteous, & conscientious. Their work was impeccable and almost a year later, I'm still enjoying my fixtures. I would highly recommend JNT (John) if you have a need. He's prompt, professional, & I felt what he quoted me as very fair and reasonable. read more

JNT Mechanical Services - Installed 3 of these in my house...all of them had 50 little strings of glass to put in. - Heating & Air Conditioning/HVAC Near Me - Morton Grove, Illinois

I noticed what seemed to me like a refrigerant leak from a copper pipe running from my AC tower into my furnace. After calling the company who installed the unit and they weren't interested in even giving me the time of the day I started searching for another company. I know enough to stay away from a couple of the big highly advertised companies and that's about it. I got lucky I came across JNT. Alex patiently and politely listened to me asked all the correct questions accurately determined it wasn't an urgent concern and got a technician out ( which isn't easy considering my upside down work schedule). It was a minor issue and so was the charge. I highly recommend JNT and know who to call and refer for the big jobs now. Now if I could only find a good carpenter...... read more

Scheduled appointment for next morning. Tech diagnosed and fixed problem within 30 minutes, fair upfront prices. Highly recommend. Thank you. read more

Our furnace wasn't working properly. Did some yelp search and contacted JNT. They came in 2 hours as promised. Peter showed up tested everything and told us that Furnace is fine , maybe just need to clean flame sensor. I am glad with service and work done. Will be contacting them again in the future. read more

I called John on a Friday afternoon, explaining that we moved into a new house in December and when first trying the AC unit on the second floor it wouldn't kick on. He was able to come about 90 minutes later and quickly addressed the issue, a broken thermostat. Luckily we had a nest sitting in our basement, and he was able to install it and we were back in business. He went above and beyond explaining our air filter system to us and gave recommendations on how to make some alterations due to our unit being in a very inconvenient place. Overall top notch service, and highly recommended. read more

Seriously, JNT really is as good as it gets!! No joke. I came home yesterday, and some time between yesterday afternoon and evening, our air conditioner went out. It was 88 yesterday and 92 today. I called JNT this morning around 10am, and was thrilled that he could fit me in today! Then he surprised me by calling and saying he could get here 3 hours early if that was convenient. It wasn't, so he changed his scheduled lunch time to fit with my need to be gone from 12-1:00pm. Who does that???? WOW! OK, and more good news, it was done quickly ("I think I have that part in my truck" and he did) and it was -such- a reasonable price. I expect to be fleeced a little in the North Shore area. Not this time! What a wonderful experience. John is both personal and professional, and I highly recommend JNT Mechanical Services! read more

John came out quickly, same-day as inquiry, on a Saturday to install a smart thermostat. Explained the process, helped with set up and stayed to answer all questions. Great service! read more

I had my air conditioner go out last night and it was super hot! I called 11 local hvac businesses at 3 am to see who would be able to come repair it the quickest. John got back to me the quickest and arrived 6 hours later. He was respectful, professional and made the repair quickly. His rates were very reasonable. Highly recommend. read more

John responded quickly to my message, and answered many of my questions even before securing the business. He came out the following day, diagnosed the issue, made the fix, and was in + out in less than an hour. He also had a better prices than any of the other companies I called. read more

Great prices, friendly people, fantastic work. I recommend them to everyone I know!! They didn't charge me anything extra even though they came on a Sunday BC my heat wasn't working. read more

We moved into a new home in December and were having problems with the heat. John came out the next day and got everything running and checked out our air conditioning system as well. He found some problems with air system and repaired that also. He explained everything he was doing and charged us much less than we had been charged at our previous location for repairs from another company. John was friendly and prompt. I would definitely recommend him for any heat or AC issues! read more

John was great to work with. My condo was no longer getting cold air in the dead of summer, so I reached out to him, seeing how many positive reviews he had. They all hold up too because he was so responsive when it came to answering my questions and made sure to come out as soon as he could! He was upfront and honest about pricing, and he did a great job of explaining what was wrong to someone who doesn't know anything at all about air conditioning. Not to mention, he was able to get my condo cooled down, a/c working within the hour. Great service and would definitely use him again! read more

John came on a Saturday to look at an electrical problem, which he quickly diagnosed. This involved repairs to the AC and rewiring some circuits. He did the work quickly in the evening and costs were extremely reasonable. John was friendly and did not try to sell us things we didn't need. We will use him in the future. read more

I have used John from general furnace maintenance to AC compressor replacement without a single hitch. He is a true professional- he helped me stay within my budget when my AC compressor at my office failed. Easy to work with, friendly, timely, and reasonable. Nothing but praises for his company. read more

What can I say about JNT Mechanical. I have a gas space heater that I couldn't get going this winter season. I managed to get by early on until it really got cold. I gave him a call and he was able to come out right away. In no time he figured out what the problem was and fixed it, he even showed me how I could take care of it myself for the next time. Very, very happy with them I will definitely used them again. read more

Never been happier with a service like this. Quick efficient and on time. Prices were right.had my compressor and my furnace redone at a very reasonable price and John who came to work on it was very knowledgeable and did not try to oversell read more

John is very friendly and his service is great. I just needed a chandelier installed and he took care of it in about 30 minutes. I'm very satisfied and definitely recommend JNT for all your AC/Heating and electrical needs. read more

We love Johnny!!! My fiancé and I just bought a house and you can say it's quite the fixer upper. When we moved in, one of the first things on our too doo list was temperature control. A childhood friend recommended JNT. We called and scheduled a appointment, Johnny came and literally fixed everything in a day! Our furnace was leaking from the PVC outlet from a bad install job and it was dripping onto the electric box where the on/off switch is located. Johnny replaced and fixed the PVC, swapped out the electrical box because it started to rust, tuned up the furnace, checked the whole system for leaks and efficiency, and then recommended and installed an Ecobee 4. Everything was done smoothly and quickly. And I'm soo happy he recommended going with the Ecobee 4 rather than the nest for more compatibility. Johnny was very knowledgeable and took the time to explain what was going right and what was going wrong and I truly appreciate that. He has certainly become my go to guy for almost everything electrical and HVAC related. Thank you Johnny!! read more

See all

John came out on a Sunday morning to fix our furnace! He even gave it a tune up. I'd highly recommend him and we'll definitely use him again in the future. read more

This company is amazing for one the PRIce !!! For two the guy (john) who came was very polite knew exactly what I was talking about when I told him the problem on the phone he didn't want to quote me of course on the phone which I get but he actually let me explain the situation over the phone and I was freaking out because my furnace was not working for two days. I've called all around town and you can just feel over the phone they want to take advantage of your situation but not (john) he was so calming and in about 35-40 he was at my house and took him 5 mins to fix the problem one quick flat rate fee warm house can't get any better than that.. If you need help make sure these guys are the first people you call you won't regret it read more

JNT Mechanical and owner John are by far the best heating/air service company we've used. John is reliable, professional, and responds immediately to all calls. He was also less than half the price of what we've paid for service in the past, with much better service. Look no further!!! read more

I give JNT a 5-star rating because: 1. They provide prompt service. They don't let customers wait long hours. They arrive at 8:20 when they say they will arrive between 8-9 am. 2. They are honest. The service man explains to me how the boiler works and what needs fixing. He also uses instruments to demonstrate the part that no longer works. 3. They are considerate. They cover their shoes before they enter my house. I am ver happy with their service, best ever:) read more

Very satisfied with their service. Technician came out, was thorough and didn't spend the entire visit trying to up-sell me. He gave me some recommendations along with some things to keep an eye one, but didn't try to push a new unit down my throat. I had my AC Unit, Furnace, Hot water heater and Sump Pumps serviced and I also had a Smart Thermostat (Ecobee3) installed. read more

John was terrific. Responded quickly and replaced my water heater. Very fast service, great products. Would absolutely recommend and use again. Tom W. read more
