I was first called at 7:30am the day of my appointment. Matt Giovannoni, service technician, called to inform me of his arrival time. He was not only on time, but was familiar with my home and my account. Matt and the Technician Manager, Henry Aguirre, briefed me in detail to service calls objectives. Meticulously performing his duties, Matt committed himself to his duties. I am very satisfied and appreciative of the attention to detail and leaving my home cleaner than when they arrived!! Very Very Pleased!!!

We had a very positive experience with Energy Services of Naperville, especially working with Keith Fortman. He was knowledgeable, professional, and took the time to answer all of my questions.
What I appreciated most was his no-pressure approach. He was honest, straightforward, and really listened to what we needed for our HVAC replacement instead of trying to push a sale. That made the whole process much more comfortable and reassuring.
I would absolutely recommend Energy Services of Naperville and Keith to anyone considering HVAC work
I also want to recognize the installation team at Energy Services of Naperville for the quality of their work. Before replacing our HVAC system, I learned how important proper installation is for efficiency and long-term performance.
The crew that installed our new Carrier furnace and air conditioner was professional, respectful of our home, and clearly knew what they were doing. They worked carefully and made sure everything was set up and running correctly before they finished.
We feel confident the system was installed the right way, and we’re very pleased with the results

Energy Services recently installed a new furnace and air conditioning system in my home, and the entire experience was excellent from start to finish. The project began right on schedule and was completed on time, exactly as promised.
Greg, the salesperson, was knowledgeable, straightforward, and communicated clearly throughout the process. The installers, Anthony and Frankie, were professional, efficient, and took great care to protect my home while they worked. The installation was clean, organized, and done with obvious attention to detail.
Once the work was complete, they tested everything thoroughly, explained the operation clearly, and made sure I was comfortable with the system before wrapping up. Cleanup was excellent - no mess left behind.
It’s refreshing to work with a company that delivers on what they promise. I would highly recommend Energy Services to anyone looking for quality HVAC work and reliable service.

Two years ago our family wrote a review praising Kevin and the team at Energy Services for their honesty, professionalism, and craftsmanship when they replaced our aging furnace. Having since moved to Wheaton, we recently had them replace our 19-year-old Carrier air conditioner, and I’m thrilled to say that our satisfaction with their service, quality, and attention to detail has not diminished one bit!
From our first call to Brian who assessed our needs and provided a same-day quote to our installation day with Jeff, who worked tirelessly through the rain, the experience was everything we remembered — prompt, transparent, and professional. Jeff treated our home as if it were his own, taking every precaution to keep his work area clean. He arrived exactly when promised, communicated clearly throughout, and was genuinely friendly and respectful.
It’s rare to find a company that maintains such high standards year after year, but Energy Services continues to set the bar for what great service should look like. We couldn’t be happier with both the experience and the results.
Highly recommended — again!

We purchased a furnace w/ humidifier and a/c unit in 2021 from Energy Services. It was competitively priced and a clean easy installation process. This appt was for our semi- annual maintenance.
This company is excellent! They communicate well, are timely and efficient.
A month ago, we had a concerning noise coming through the air return. The technician called ahead of our scheduled appt, explained what to try and to call back if it continued. Otherwise, it could wait until our maintenance in January. That saved us the cost of an unneeded visit and tells us they want to do a great job without nickel and diming their clients.
