Yaseen (Jessie?) was great! Personable, knowledgeable, efficient and he took the time to explain everything. I request to have him for the Spring A/C tune-up.
I've now used Energy Services for 12 years. There's been some recent dissatisfaction on Yelp due to missed appointments, but the technician (Yahir) did finally arrive after a full day, and spent over an hour checking and cleaning my air conditioning. He was thorough, knowledgeable, and very courteous, and wanted…
I've been a customer for over 12 years and recently had the pleasure of having Rakia perform a service cleaning on our AC unit that Energy Services installed in 2025. Rakia did an excellent job cleaning and inspecting the unit. She was very thorough, friendly, professional, knowledgeable, and a pleasure to deal…
Susan Blase performed a HVAC inspection. It was our first service call in our new condo. She explained how the system worked and the status of our AC unit. She was efficient and friendly.
I have been using energy services for a long time. They are very professional and do an amazing job be it maintenance or installation. The service personnel are very courteous and detail oriented.
Very comprehensive; technician explained everything.
Ok
Love this company as my parents used them and now we use them at the same house! Our outstanding service person today was Rakia. We're keeping her!! Office staff, Michelle, was also incredible!! 😁❤️👍🏼
Quick and efficient service
Mohammed came by to do some maintenance on my A/C system. He was thorough, walked me through his process, and expertly answered any questions I had. I am very satisfied with the services provided by Eneregy Services.
Jose was very helpful and explained everything he did to service our air conditioner.
Friendly, professional service. Every time!
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.
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…
Alonzo did a super job...very very polite and professional. Thank you.
Lowry came to my home to provide annual service on my two (2) air conditioning units. He was very thorough and completed the job on a timely basis. He provided great communication on the condition of the units. He identified a problem and made arrangements for parts to be ordered. He did such a great job that I…
On the morning of July 24th, the temperature was headed towards 90+ degrees. As my wife and I were finishing breakfast, I notice that the AC unit outside the house was making more noise that usual. This was pretty easy to tell because you don't normally hear anything. I went outside for a closer look, and sure…
Susan is the best technician! She is polite, professional, and patient. She took the time to explain every detail. She is an exceptional role model to any female considering her profession.
Professional and knowledgeable technician! Very detailed, explained everything ! Thanks Brandon !
First, Andrew was fantastic. Explained everything and was super patient with my aging Mom. 5 stars are for him. More if they’d let me. However we have managed multiple properties with this company. The company has canceled/ no showed for two appointments at my property. One day I sat around waiting all day for…
I can't say enough good things about this company. Have used them for 30+ years. They've serviced and installed our HVAC systems. Dependable, trustworthy, and thoroughly professional. From the telephone reception to consult, through sales and service, truly outstanding. Today's visit by Brandon Vasquez was more of…
Great job. Fast and efficient. He’s following up regarding the leveling of the bases on the AC’s and I appreciate that. I’ve been a customer for many years and have had my current system installed by Energy Services. A great Naperville based business.
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.
The technician called to let me know he was on his way. The service was done professionally and he answered all my questions. He was very pleasant and helpful.
Brandon was the tech who serviced my air conditioner on 7/7/26. Ha He is professional, knowledgable and informative and representative of every employee I have encountered from Energy Services over the years. I highly recommend this company.
Great customer service by Alfonso Alvarez! Very knowledgeable and explained everything but unable to explain a small puddle on top of the part that holds the filter. The person that came to clean it in May said nothing about possibly replacing motors etc…..didn’t get much peace of mind unfortunately, but he was a…
I have been a loyal customer of Energy Services for more than 10 years, which makes this experience especially disappointing. My annual maintenance appointment, scheduled six months in advance during my previous HVAC service visit, was canceled by the company just one hour before the technician was due to arrive.…
GREAT EXPLANATION ON WORK PERFORMED VERY HAPPY WITH ANDREW PROFESSIONAL APPROACH
We have been using this company for many years and have been pleased with the service. Matt did an excellent job maintaining our systems.
This company appears to be changing from the very customer oriented one it used to be into a more purely profit focused corporate entity. The preventive maintenance call seemed less thorough than it used to be. Needless upselling has entered the picture. They implemented a new virtual assistant taking their phone…
As always, I'm completely satisfied with Energy Service's and Jose's servicing of my AC system! He was quick, thorough, and prompt! Thank you!
Always great service!
Hailey did an awesome job. She assessed the problem and coordinated the energy services team for pricing and scheduling to ensure our problem gets addressed in a short period not time. Although we had an offer from another vendor for the dehumidifier, we committed to go with Energy services due to the quality of…
Excellent, prompt, careful of my home, very thorough…would recommend
Energy Services work has always been exceptional. Always great techs.
Andy, Service Tech, did a great job and gave me a thorough review of the system which allows to keep the overall system performance. Parts needed to repair a part that was moving toward failure were on his service truck and installed quickly and effectively. In addition, Andy completed training of a new employee…
Service was prompt and very professional. Technician arrived on time as scheduled. Good job.
Henry did a great job. He was on time, very polite, and explained the service he provided on our air-conditioning unit. He also explained my options for continued maintenance on my furnace, humidifier, and A/C along with some of the new programs associated with the new company.
Jose came out for our AC check up before summer He was professional, competent and friendly. He also explained the updated service plans to us and answered our questions. We have been satisfied customers of Energy Services for many years.
Henry did a great job. Called in advance and arrived on time. Very neat, answered all my questions; explained changes coming in the future.
Susan was personable and knowledgeable.
I highly recommend Energy Services. All technicians are well trained professionals and very pleasant to work with. Consistently good experiences
Nothing but world class service. The best
Excellent service provided by Henry.
Andrew Sherman with Energy Services did a thorough job with our six month routine maintenance. He answered all our questions, and was friendly and patient in teaching us how to adjust the smart thermostat. Andrew provided pictures of the inspection work and a written summary that helps us keep good records and make sure everything is operating well.
Always friendly and professional service.
Brandon was very helpful, fixed the problem, and offered several recommendations about how to prevent a reoccurrence.
Tech is professional, on time and did a great job
Matt G. was very helpful and knowledgeable. He answered all of my questions regarding our current system and future systems we are considering. He was fantastic to point out that our water heater was rusted and showed signs it had leaked at some point. Gave us quotes for new one- tank and tankless. But without…
Brandon was polite and courteous. Answered questions explained the alerts on the system.
I have used Energy Services ever since we moved into our new home 8 years ago. David is the best technician! He is prompt, courteous, knowledgeable and friendly. I wouldn't want anyone else to service my AC/heating units. Energy Services is by far the best, most reliable company for my heating and air conditioning needs.
Carlos was very thorough in our annual air conditioner maintenance! Very impressed with his level of detail during our appointment.
Energy Services exceeded expectations with prompt, professional service and meticulous attention to detail. Highly recommended.
I had my AC unit serviced by Energy Services Air Conditioning and Heating Company for years, and was extremely impressed with their professionalism. The technician Brandon arrived on time, explained the maintenance process clearly, and answered all my questions. My AC is now running much more efficiently after a…
The technician, Carlos did a good job. He explained what he did and cleaned before he left.
Friendly professional, efficient
Dan is very professional, efficient, thorough, polite, and knowledgeable. Highly Recommend.
on time service, easy quick and great. Carlos was personable and professional. Thanks
always professional and friendly employees with flexible availability. i feel confident in their skills and will definitely recommend to friends and family. henry was great, good at explaining things to the layperson and very professional!
Very impressed with Energy Services from the phone call to advise A/C not working, to immediate fast appointment within hours, to David the technician who was extremely talented in getting our A/C up and running again. Thank you!
The tech showed up on schedule, quickly diagnosed the problems for both the heating and cooling units. Provided the proper repairs in an extremely timely fashion. Instructed owner on the use of a new thermostat. A high quality job with expert technicians.
Andrew serviced my air conditioner and fixed the problem of the unit going on and off constantly
They are always on time. Very knowledgeable. They called to reschedule my A/C maintenance because they had a cancellation and could come a month earlier than my scheduled appointment. I appreciate that they are always looking out for their customers.
The technician, Matt, that did my AC clean and check was very thorough and took time to explain everything he was doing. I really appreciate that as a first time homeowner.
Great experience!!! Very professional folks!
Very professional and quality service.
Carlos gave us phenomenal service!!! He arrived exactly at 8:00am. Carlos is an excellent, knowledgeable technician for Energy Services! He called in advance to give me his ETA. He was very careful to be clean and precise in his work (mask and shoe covers are greatly appreciated). Thanks to Carlos and Energy…
I originally went with Energy services after researching 5 or 6 companies. They were the most detailed and comprehensive in their furnace cleaning protocols, not the cheapest but good price and great service! Anthony our service guy is great and remembers stuff about us! Matt went above and beyond!
Have had equipment installed and servicing done with them for 25+ years. Simply the best -especially the technicians who are always super professional. Special kudos to Greg-the best tech who’s been doing service and repairs on my furnace and air since the beginning!!
We love Energy Services! Matt was amazing. I wouldn’t trust our heating and cooling to anyone else! Including myself.
I have been a customer of Energy services for 19 years. When it came time to replace my furnace they were my first choice. I ultimately replaced the air conditioning with a heat pump as well and that was a great decision. Everyone that has been sent to my home has been knowledgeable, polite and respectful. David…
We have used Energy Services for 12 years and the prior owners of our home were customers since the early 90’s. Always honest, polite and professional. Never have we had an issue getting an appointment and never have we had a complaint.
They’ve been great when we have them come out for regular maintenance. You can tell they’re actually trying to help you avoid issues and seems like you’re getting your moneys worth with a great team.
David provides great service and is very thorough in his work.
I have used Alan Heating (Energy Services) close to 40 years.
I have used Energy Services for over 20 years and have always been very pleased with their service and the quality of their technicians and management.
Professional, timely, efficient and will use them again!
Scheduled a spring check up. Patrick was service tech. He is very nice and professional. It is nice to see the same person return to my house to perform the maintenance work. The team at Energy Services is great to work with.
On time, professional & thorough.
David Beam has been to our house a few times. He’s always on time, quick and efficient. A very nice guy!
On time, very professional, explained everything.
Very professional and did an excellent job cleaning/ maintenance on my ACs.
Was able to get a tech out right away to diagnose my AC issue. Would recommend
When David comes to service our system I’m confident that he’ll make sure it’s in good working order. Thank you!
Prompt, courtious and excellent work ethic, what more could you ask?
Jason G and Henry A have been consistently great. From new construction install through current date for regular seasonal maintenance calls and a few other visits due to my requested addons/upgrades.
Matt was very knowledgeable and efficient. He was honest with us about what work needed to be considered and done on our furnace and humidifier. He helped us to understand everything well too. Our humidifier stopped working, and he helped us navigate the installation and pricing along with Keith very well. Would highly recommend.
We have had our A/C and furnace maintained by Energy Services for the past several years, and have been quite happy with their prompt and competent service. On the most recent maintenance visit, the technician, Jonathan, in addition to maintaining the furnace and humidifier, noticed and corrected a problem with our…
Being a long time customer, i am always aware of the professionalism of the employees who visit twice a year, once for A/C and once for the furnace. the service received is A+ and look forward to each visit knowing i am in good hands
They did a great job!
On time, and very professional. He did an excellent job of explaining what is going on with the system.
I just wanted to call out our service tech, Steve M, for doing an outstanding job! He was super professional and personable, and was extremely knowledgeable of our issue. He talked to me for about ten minutes prior to his arrival to start troubleshooting the potential issues. By the time he arrived, he already knew…
Greg was all things you would want. Timely, courteous, thorough, detail-oriented, and efficient. Alan Heating & Cooling is best in class
Gregory has been out to our house multiple times throughout the years and is always very professional and informational. We definitely trust him for all our heating/air conditioning needs!! Thank you!
Update: Carlos & Brandon arrived at our house on time today to clean out our ducts and vents. We had a large amount of dust and other things in our ducts from the builders. Carlos and Brandon were AMAZING as they came in and addressed an issue we were having with the furnace 1st then proceeded to work the entire…
Awesome service! John was our technician. The minute he approached our house for a air condition problem, I was welcomed with such grace and friendliness. He answered all our questions with pure honesty and gave us suggestions to help manage any future issues. I loved how he explained the diagnosis in such a way…
Very professional and efficient technician. Always good service
Be very careful - extreme Predatory pricing. The A/C unit was making a very loud noice and it was clear either the motor or the compressor was gone. As he did his diagnostics he asked for a hose and proceeded to hose the unit down. He did NOT tell me that it would cost me $89 for someone to hose a unit down and I…
We have used Energy Services for years and have always been impressed with their service, reliability, and attention to detail. We highly recommend them.
I don’t usually write bad reviews but this was the last straw. My AC broke and this company was called to fix it. They charged me 300 dollars for a part and I ended finding out that the part was only 50:dollars. I called them and did end getting a refund for it but it’s ridiculous this even happened.
Great services quality service guy
My service technician was friendly, professional and timely. She has been in our house multiple times servicing our hvac equipment. I've done business with Energy Services for over 10 years and I give them the highest possible recommendation!
Very professional, very thorough.
I have used this company for 20 years and always received very good, reliable service. Over the years they have replaced 2 furnaces and one air conditioner. First furnace did not hold up as long as it should have, but second one has been great (that's why just 4 stars). Personnel are friendly and seem knowledgeable . I highly recommend.
We've used ES for over 25 years in two homes in this area. They've always been professional, very open about services needed, prices, and are on time, neat and the job is always done right. You can't go wrong with ES.
Steve was great and very professional. Energy Services is very lucky to have him.
I can not say enough good things about this company!! They have ALWAYS been very professional and accommodating! We had them install a new HVAC system, they do maintenance every year, and have honored the warranty without issue (unheard of these days)! We had an issue with the air recently, within an hour of my…
