Still waiting to get an answer to proper installation of furnace filter, which is disappointing as maintenance service is usually very prompt. I took a star away for that reason.

Serviceman was tremendous but call in service was dismissive and very unhelpful. This is 100% different occurrence today from past call in. Every time in the past the people have been very, very helpful
It was an absolute pleasure working with Mohammed! He patiently answered all my questions and gave me detailed explanations on how my HVAC worked. When he found 3 mice in my heater he figured out how they got in and took care of that. Then he carefully cleaned everything and left me with simple directions on how…

Energy Services always impressed me until this year. Not anymore. They cancelled my AC annual maintenance service call that was scheduled for June (2026) and the earliest they could reschedule was today (9/17) sometime between 8-Noon. I called at 10 to get the time the tech will be here. No one available, I left…
The workers were on time and did an excellent job. Best deal among 3 bids.
Technician Salvador was very courteous, professional and efficient. Not sure what the issue is with the appointment system however is as I received 3 calls about the appointment while the technician was already here
Had system Maintenance done today with Muhammad ,although we have been with Steve for almost 20 years. I must say I was reluctant to see anyone else at my door and yet was so pleasantly surprised with the service I received from Muhammad that only did I learn a little bit more about my HVAC. He was patient enough…

Yahir was very knowledgeable and professional. I appreciated his expertise and service-minded attitude.
Martin was friendly, prompt and able to answer any questions. He was very polite, personable and professional.
Caprell did an excellent job, and was very knowledgeable. Your appointment system using AI is terrible. I called 6 times this morning to get an arrival time, and was never able to get to a person! This will drive customers away.
Excellent service. Professional and provided clear explanation of services
Andrew was thorough in his inspection of my HVAC system. He shared with me the ratings of the components and its current levels, with pictures.
Great job. Hard workers in 90 degree heat. Left the work area clean Highly recommend!
Joe responded to my follow up question/concern about my recent service with well-explained analysis and advice. I have always had a very good service from their team.
I have used Energy Services to do all of the maintenance on my furnace and a/c for years. My technician, David Beam, is friendly, professional, efficient, and on time. I always request him. UPDATE: Aug.2026 I have since left this company and changed my rating from 5 to 2 stars. It was bought out by a bigger company…
Knowledgeable and warm personality. A credit to your firm
All the service technicians seemed knowledgeable and were friendly. No pressure when they are telling you about some things that could be repaired but not critical. **UPDATE** I'm moving my rating from 4 to 2 starts. I mentioned there was no pressure from the technician to install the parts. But Holly from the…
Confirmed with the company three times that I would be home after three however, the service man showed up at 12:30. The scheduler gave me attitude. Even confirm the day off after 3 o’clock. Not much service was done. Would not recommend this company again.
Prepaid maintenance visit. Very knowledgeable. Pointed out what they thought needed replacement. Some parts, yes. But all, no. It felt like a sales call for a new system while this one is still under warranty. Quotes for repair and replacement seemed high. Still, good to know what the options are.
Excellent service as always. Yahir was great, explained the system diagnostics and kept me updated on the inspection and progress.
Energy Services performed annual AC maintenance . Knowledgeable technician. Coordinated visit efficiently in spite of threatening weather. We use the annual maintenance plan which also covers the furnace and humidifier in the winter. Very reasonable and convenient.
Professional and very knowledgeable
Andrew was a nice and polite young man. I had 100% confidence in him.
Energy Services installed a new furnace and air conditioner in July 2024. They took the time to explain the new system and the technology involved. The air conditioning worked great and was more cost efficient than our previous unit. Middle of October we switched to heat and we received an alert email that required…
The tech was great. Very personable and explained everything he was doing.
Great service and friendly worker!
Great Tech!!! Very professional & detail oriented in making sure the work was done right on purpose A/C unit.
Unfortunately, the level of service at Energy Services has changed under its new ownership. Routine maintenance now appears to require an additional subscription, and even basic items—such as inspecting the ERV, an important part of the home’s air filtration system—are no longer included unless you pay extra. I…
Energy Services are thorough and knowledgeable. They are courteous and respectful during the visit.
Susan is knowledgeable personable and very thorough Energy service is serving my house for 40+yrs
I really love having Energy Services for both new purchases to update HVAC and setting up and receiving spring and fall maintenance for both our heating and air conditioning needs. Definitely a high quality and consumer oriented service company that has served us many years.

We have been with Energy Services since moving to Naperville 26 years ago.

The techs that come around to service the units are always…
He was professional and answered all our questions. I had the annual maintenance that is included in the monthly fee that I am paying for furnace and air conditioner. Well worth the price and peace of mind
Our tech, Dan was great-5 stars. Polite, competent, efficient and helpful with some questions. I was less impressed with Energy Services’s unwillingness to commit to a window of time as to when the service call would occur.

They always take the time to explain everything that they do. I feel I can trust them.
Great company to deal with for install & service. I been using them for several years on my furnace (which they installed) and A/C.
2 young men arrived on time, careful to lay protection to all flooring (carpeting, etc) clean and efficient throught the day long process. Excellent job. Thanks
Hailey Ratcliff did a fast great job TY
Caprell did a great job checking over my AC system. He also gave me suggestions to keep my system going strong. I appreciate that. Already pulled out the plants in my yard that were threatening to block the air from my AC unit.
Alfonso was efficient, friendly, and able to get my AC running quickly, a real blessing in this heat wave. He even made arrangements to have my furnace filter replaced the next day, which would have been a problem for me as I'm recovering from surgery and not as mobile as I'd like to be. All in all, a perfect service appointment!
Martin Carranzo-Santos was excellent—prompt, polite, and thorough in ensuring everything was in good working order. He kept me well-informed throughout the process and made sure I understood the work being done. I highly recommend Martin for any HVAC services. However, I had a very poor experience with the new AI…

Technicians that came today were excellent. Hailey, Scott and his assistant (sorry did not catch name!) were all professional, informative and detailed. The services are expensive but if you want the job done right this company has well-trained employees who are consistently excellent.

I highly recommend Energy Services. They are prompt and professional. Every time they service our furnace or air conditioner they do a great job.
