All reviews for JDN Heating & Air Conditioning Systems

An excellent choice with JDN Systems. Mike came quickly and installed a brand new AC system for me. He was in and out fast, very efficient. I appreciate his support. Thanks Mike!

First HOT day of summer and cooling unit stopped working, called a couple of local places and they were all focused on the initial visit cost. Mike from JDN asked about the system and was able to come out the same day to look at it. The kind of honestly and care he showed is hard to find these days. He looked at the whole system (17 years) old and recommended a replacement. Two days later he and his son showed up and installed the new Trane system and even gave us a new touch screen thermostat. They even cleaned the area and explained the features. They have definitely earned me as a life long customer. Highly recommend them for any HVAC needs.

Thanks Mike.

JDN Heating & Air is the BEST! This is a family owned and operated business that really CARES about you! The service, response time and quality of their work is OUTSTANDING!! I promise you won't be disappointed if you choose JDN for all of your HVAC Services!!

Mike and crew are reliable, honest, and trustworthy. Don't be fooled by those false advertisements at hardware stores because we ended up spending twice as much as what Mike would have charged us. Never again! Going forward they will be our only go to techs for our HVAC system. Thanks JDN!

I have nothing but praise for the service I've received from JDN Heating. In 2018 JDN installed a new Trane furnace and air conditioner in my home. The price was competitive and the work was first rate. I've been very happy with the new equipment especially when compared to the 25 year old unit it replaced. On hot days the old air conditioner would never turn off. Despite running almost constantly the old unit just couldn't keep up and the temperature in the house would creep higher. The new Trane unit cycles normally and has no problem cooling the home evenly. The new Trane furnace is also a major improvement over the unit it replaced. Temperatures throughout the home are more consistent which is a welcome change from the uneven heating we grappled with before the upgrade. Recently (Sep-19) we noticed the a/c was generating excessive amounts of condensation and called JDN for help. Mike and Nathan responded promptly to our call. The source of the problem was difficult to pinpoint but JDN was committed to finding a solution and they did. Though it took a number of hours over several days to put things right we were not charged for parts or labor. Really excellent service. In short we're completely satisfied with the service and equipment JDN has provided. If you're looking for HVAC equipment JDN would be an excellent choice.

I been using JDN since I moved out to the western suburbs from Chicago back in 2008. They have been nothing but great and their service even better. They aren't the cheapest but not the most expensive either. Their prices are fair and workmanship is very professional.

Extremely impressed and very satisfied with the professional service provided by Mike and Nathan of JDN. The quality of their service and the thorough explanation they provided was especially appreciated. I would highly recomend them to my neighbors, family and friends. Timely, professional and very knowledgable. They replaced a 16 year old unit with a much more energy efficient new one. Very pleased.

Incredibly old unit started to freeze over, Mike came within hours. Confirmed we needed a new system. Was able to get the old unit up and running for the awfully hot weekend ahead until they were able to replace. Had our new ac and furnace installed by Wednesday. Fast, efficient. These men were kind and explained everything that they did and how to maintain the system amazingly. No one else will ever touch our home for heating and ac.

We have been using JDN Systems for many years. This was the first time I needed to understand our air conditioning units and their corresponding controlers. JDN (Mike and his team) has been to our facility several times, but I have not had the chance to work with him directly. Mike took the time to walk me through the building and explain our 5+ units and the corresponding thermostats. He also took the time to explain to me why our units weren't working and what we need to do to keeping them running properly. As a women, I felt very comfortable with Mike and he respected my questions and helped me understand our facility much better when we were short handed in our office.
I would recommend JDN. The response time was also less than 24 hours during August.

Nathan was the technician that came to my home to repair my furnace. He was on time, polite, and very knowledgeable of his profession. This is my first time using JDN Systems. I will continue to use their company for further repairs, and I would HIGHLY recommend them to anyone that is in need of their assistance.

As always, Nate is so nice and professional and took care of everything.
Also, for those of you that do not have an air scrubber on your system, check it out with JDN....I love mine!

Frank from JDN did a great job getting our furnace ready for winter. Very efficient and patiently answered all my questions. Great job Frank!

JDN Systems provides fast and professional service. Mike is always pleasant and very knowledgeable. We've used them for several years now and have never been disappointed with the service or prices they provided.

Had our Furnace and Air Conditioner replaced by JDN awhile back. Have not had one problem! Had them out today for routine cleaning. Prices are best around and I can highly recommend using them for all your HVAC needs.

JDN Systems provided same-day service right before a 3-day weekend. The technician was friendly, knowledgeable and efficient. The air conditioner is high quality (Trane) and has a great warranty. Cash discount was a bonus! Highly recommended!

We have been customers of JDN Systems for many years here in Bartlett and today I was reminded why. Over the years, JDN has installed a new HVAC system (AC & Furnace after the old system gave out) and they have provided yearly maintenance for both systems as well.

Today, t's Sunday (6/28/20), hot as hades and humid and the outdoor compressor was turning on and off constantly. I knew that was not a good sign. I called JDN and left a message thinking, its Sunday and I'll have to wait until maybe Monday to hear back and was bracing for a difficult rest of the day and night's sleep. I was pleasantly surprised to get a call back in about 15 minutes with the Owner saying he has already sent someone to the house and they should arrive soon. To our relief, the issue was identified and then resolved. The AC was back on-line and working as designed.

We highly recommend JDN Systems and personally, as someone who is in the construction and real estate industry, and as a Licensed Architect and Senior Project Manager on facilities across the country, their services are outstanding.

Thank you Mike and Nat!

Nathan and JDN are exactly what you need: honest, competent and efficient. This family business is a credit to our community, and I highly recommend them.

Great company - responsive & easy to work with. Nate was very accommodating & has great workmanship. Glad to have found a reliable local company that can exceed our needs.

The fellas at JDN really impressed me with my repair of the heating/ac unit. I was totally prepared for a total replacement after being told by a previous contractor that it had to be replaced. I decided to get an additional estimate for replacement and after JDN inspected it, it only needed a replacement part. They saved me thousands that I was prepared to spend and instead gained a loyal customer for life! I would strongly recommend them.

Great guy, fast , fair . Went the extra mile . On the hottest day of the year!! Il recommend them to everyone, thanks Nathan!

JDN replaced our furnace and air conditioning units and we couldn't be more pleased. Mike is extremely knowledgeable and talked us through the entire process. It made a huge difference in the air quality and comfort of our home and we would recommend this company to anyone.
