Stay away from this business! My entire cooling and heating system was left in an inoperable state. I called for a diagnostic of the air conditioner today because cool air isn't coming from the vents. I was told the diagnostic would cost $149. I asked to be informed of any repairs that had to be done. Technician checked the system and recommended replacing unit. We discussed replacement unit and cost. I was ready to pay deposit. In the next 10 minutes I was told that the model I selected is old and not available. New model costs $1000 more. I asked for a proposal to decide later. Technician told me that the visit costs $396. He said that he fixed air conditioner that was not working. He never told me that he is fixing anything. Through our the visit it looked like he was figuring out the problem. I talked to the owner and we agreed that any repairs that were done will be undone so that I do not have to pay for repairs. Then the technician removed all the wires from the board making both heat and fan unusable. He did not just undo the "repairs", but made entire system unusable including fan and heat which were working before his visit. See the photos to show what was done! read more

Reply to 2 reactions from Harmonic on my 1 star review. 1. A. & K. claimed A. fixed my heater Tuesday; lie. Bad customer service. Harmonic deserves 1 star, but all the starts below 5 are NOT indicated on the Google graphic of the numbers of review stars 1-4: false. 2. I never promised a review pull-down for a discount. My husband & I have better things to do than having an "agenda" as Harmonic accused. My husband was on a business trip. 3. I never called for an emergency repair. I did not switch from repair to cleaning & maintenance. I asked A. if C & M was possible afterward, unaware of 2 more with no heat. Harmonic called me "selfish" for this. 4. Any possibility A. and K. have unconscious biases towards people like me? They accused us of "manipulating" what? To save a few hundred bucks, while we spent in the tens of thousands at Harmonic's better former (aquired) company) you imagined up? 5. How could Harmonic accuse me of lying about my pain. Because I was able to and had to carry my 10 lb dog for a short moment because of her barkin? Why do I even have to explain my chronic severe back pain and mostly failed back surgeries and weak immune system? 6. I had no "agenda," but getting my heate fixed. I am not playing any "game" as accused. I am standing up for myself. 7. K.'s statistics on the number of my Goole reviews are false. 8. A. & K. are the ones who were "aggressive, harsh, unethical, disrespectful, and manipulative." Stop projecting and gaslighting. I wish I would remember to record conversations when I am alone with a person like A. Why did K pull down his absurd replies on Google? read more

Within one hour of my call Nate was at the house to repair the furnace. He did a fantastic job and got it working within 30 minutes. Excellent customer service. The cost of the work done too was reasonable. I will definitely hire them again for HVAC needs. Thank you !! read more

Harmonic consistently delivers excellent customer care beginning with their office when scheduling the appointment. Reece showed up on time, patiently explained how to change the filter on the humidifier, completed a full maintenance on our furnace and then reviewed what had been completed. I would strongly recommend the Rock Star Program that provides furnace maintenance in the fall and AC maintenance in the spring along with other perks that are included. It is very affordable and guarantees your furnace and AC are well maintained. Overall, a 5 star experience with Harmonic and I would highly recommend them for any furnace or AC needs. read more

They were great! They arrived when expected, did a thorough job, and charged me what they had quoted. No hard sales pitch. The 2 technicians were professional. I would definitely call on them again! read more

Needed help for my in laws house, very responsive, reasonable and clear pricing. And best of all, got the job done! Highly recommend.

On time, very professional and were very good at explaining everything. They gave me information to help in making the unit more efficient that I could do. Gave me an estimate before they did any work and the cost was reasonable. I would definitely use them again. read more

Chris and Reece came out for the annual AC clean out and maintenance. Arrived on time, respectful of my home and property as well very polite and friendly. They worked quickly and efficiently with no issues found. Left work areas clean and wore shoe covers. AC blowing cold, ready for summer! read more

Dude came out for a cleaning. Was polite, straightforward, and ontime. Had a 20 year old unit and said it was clean and well maintained. Could have made a buck, but played it straight. Much appreciated. read more

Recently had Harmonics assess a 12 year old water heater that had a faulty sensor. The technician suggested that cleaning the unit would help the problem. It did not and I ended up paying 175+ dollars after the service charge and cleaning, none of which would go towards the valve that he said now needed to be replaced. After the fact I find it questionable that he recommended that the unit be cleaned and valve replaced given the unit is at the end of its life. My fault for not trusting my common sense. Having worked with numerous service companies you know the good ones are those that leave you with the impression that they are looking out for your best interest instead of taking the opportunity to upsell you on unrelated services. That's not the impression I got from Harmonics. On a more positive note the woman on the phone was pleasant and responsive. Edit: to clarify their response below, they do not provide a credit up front. Only after I called to express my concerns did they offer a credit towards future purchases. read more

We requested a quote from Harmonic to replace some rusted duct work in our basement. Sean was able to come and provide a quote the same day we were able to schedule the repair within the week. Brandon, Chris and Reese were able to replace the damaged parts. They completed the repair in a timely manner, cleaned up the work area and were very thorough in their explanation of the work completed. I would highly recommend this business. read more

Our A/c wasn't blowing cold air in a house we just bought. We had another company come over and diagnose the problem, after the diagnoses, we were told it needed a whole new system $6000 dollars...Same day I called Harmonic and Daniel was at my door within 45 mins and diagnosed our A/C that just needed a 200 dollar part and some freon...If you have A/C or Heating issues, start with these guys first!! read more

I don't usually write reviews but Nate from Harmonic just left and I'm very relieved. A company I used for many years recommended two costly repairs and said I might as well replace the whole furnace. Nate showed me that I likely had some time left for the existing furnace and while it wasn't a great one, it wasn't an emergency situation as the other other company had claimed. I appreciated his honesty because he could have given me the same dire story as the other contractor. I immediately put Harmonic's number in my phone because when I do need a service, I will call Harmonic. read more

DO NOT USE THIS COMPANY! RIPOFF ARTISTS! CHEATS! LIARS! Danny, the lead tech replaced a thermostat for me today. He did not discuss options or pricing prior to taking it out of the box and placing it on the wall. Keep in mind - there was no hard wiring done. He JUST hung the thermostat. My total bill was $459. He charged me $380 for the thermostat that RETAILS FOR $45. (This is a very basic, non wifi thermostat). I was shocked when he told me the price, but hadn't done the research to see what a complete RIP OFF this company attempted. I spoke with the owner, Jeremy, who agreed the price was high and then proceeded to justify this ridiculous charge. He sited overhead expenses, salaries, etc. I found him to be extremely patronizing. There is no excuse for an almost 1000% MARK UP! It is such a shame that the previous co-owner who was reliable and honest left the company...GEEEEEE - I wonder why he left?!?! I recommend using Brian's HVAC for quality work at a FAIR PRICE! read more

Our AC wasn't cooling the house last summer. The guy came and tried everything to talk me into getting a new system. We decided to instead try antifreeze first. I got a big talking about how I might have a leak, it's expensive, it's going to be obsolete soon, and I needed a lot of it potentially due to our issues. Turns out-no leak and I only needed a little. $200 fix and I was being coerced to replace the entire thing. Glad I went with my gut! No issues all summer after that. read more

Harmonic Heating and Air Conditioning is the BEST!!! Our AC died and after another company told us that our unit could not be repaired and had to be replaced ($6,000), we contacted Harmonic for a second opinion. Daniel the service technician opened the unit up and tested everything. He took the time to explain what he was doing and why. He discovered a bare wire that had been chewed (possibly by a mouse) and was touching the metal housing which tripped the circuit breaker. Daniel replaced the wire and the unit is working perfectly. The honesty and integrity of this company is refreshing. We will not hesitate to use them again and recommend them to all our friends. read more

First time using their services this month and was pleased from start to finish. They came out the same day, diagnosed and explained the issue, and the price was fair. They needed to come out the the following day again due to not having the filter on them (which was fine), but they came at the time they said they would. Shaun was the tech. They also wore booties and were masked. read more

These guys are awesome!!! They came out to put in our heating and air system with the crew and all. Poor guys were in our hot attic for a few days but they never complained and were happy to do the job! The guys were very polite and they cleaned up after themselves. I would definitely recommend Harmonic to family and friends! They are the go to guys for all your heating and air! Thanks Jeremy and Harmonic crew!!! We are loving the air right now! read more

Harmonic Heating & Air Conditioning Naperville - Love these trucks! - Heating & Air Conditioning/HVAC Near Me - Naperville, Illinois

We have had a contract with Harmonic for a little over 2 years now. From your first interaction phone call with Liz to every single interaction with the technicians, I cant stay enough kind things about everyone at Harmonic. Since buying our house, we need a new furnace, A/C unit AND water heater. Harmonic has come out quickly, they work efficiently and explain everything so we understand the new systems we have in our house. They also come out once a season to check our furnace and AC so we are good to go when we turn them on. They're even extremely kind to our kids and dog. Thank you, Harmonic! read more

Services: A/C / Furnace Replacement Brand: Trane Models: XL80, XR13 City: Naperville, IL Quote: Decent, I searched 12 companies and Harmonic's was he in the bottom 25% and he was able to quote over the phone (3 of the companies I searched would not offer this... disappointing). Most importantly, he was punctual. When you schedule a quote, visit, or install, plan on Harmonic being there 15 minutes early. Price: Accurate to the quote. Harmonic did not try to up-sell and in fact recommended a mid-grade model rather than a high-grade for my needs. As a measure of Jeremy's honesty, I asked for him to hook up my humidifier to my Nest thermostat. He quoted me an extra $250, which I thought was fair, based on the wall drilling, attic crawling, and line running that he would have had to do. He ended up not having to run wires because there were existing wires in place (unbeknownst to me). He let me know and hooked it up for no charge. Specialty Knowledge: Jeremy owns the business. When you call you will be talking directly to him. I had ~10 questions lined up for each one of the companies I searched: Brands, Price, Installation, Licensing & Insurance, Date of Install, Labor Costs, Payment Options, etc... Only two of the companies I researched actually took the time to discuss. Tess @ Air Repair Heating & Air Conditioning, and Jeremy @ Harmonic. I went with Harmonic because Air Repair Heating offers Rheem which is inferior to the Trane systems offered by Harmonic, with similar pricing. I was on the phone with both of these companies for at least 30 minutes having all my questions answered. Service: I have no complaints. His team was efficient, punctual, clean, and courteous. On the date of install He showed up in his company vehicle, followed directly by a company truck. Five minutes later, while I was on my way out the front door, another truck showed up with both the units. Like clockwork folks... Both units were installed in ~6 hours (mind you, my house is a single story ranch with little/no modifications needing to be done) Website: Excellent presentation and ease of use. One thing that did turn me off was the lack of "NATE Certification" that some other companies seemed to take pride in. This bothered me at first, but after talking with Harmonic over the phone, I was completely at ease. Also I know Trane, Carrier, and other top brands are very selective about who they allow to install their products. Advice: Do your homework, compile your questions, create an excel spreadsheet, pick the company that meets your price point and expectations. Call Jeremy @ Harmonic last, and see how he stacks up, then choose Harmonic... End Result: Ice cold air, Fair price, Excellent Service, Happy Homeowner. read more

I stumbled across Harmonic maybe a year or two ago after having a ultra bad experience with another local HVAC company who actually made fun of me for buying a $250 thermostat instead of just helping me install my Nest. Harmonic consists of a team of super friendly young guys who are all about the latest technology, so we jived well right off the bat. When my furnace died earlier this week, they were the first people I called. Turns out the problem was with my blower motor, which they were more than happy to replace for me, but I fully realized with how old my furnace was all I was doing was applying a very expensive band-aid to a much larger, totally inevitable problem. I knew when I bought my house it had an ancient furnace from the 80's, so I've been planning for this day for quite a while. Without much hesitation, I signed on for the full enchilada of replacing my dead furnace, dying AC, and finally ditching my janky humidifier that I have to refill multiple times a day for a automatic full-house humidifier- I even sprang for their air purifier. Go big or go home, right? Once I agreed to the quote and we scheduled the install, Harmonic actually did me a huge solid- I had all my warm blankets and space heaters out and was already coming to terms with the idea of being supremely cold until they could come back a couple days later with the new furnace, but they actually ended up just putting in a loaner blower motor for free, which they then just took back when they hauled my old furnace out. Totally unexpected for them to be willing to do that, but totally awesome. (I actually ended up writing a check as if they had done the blower motor replacement service instead, which they gave back to me when they returned for the install in case I changed my mind.) This kind of stuff always makes me super loyal to repair guys, as they TOTALLY could have been like, "Yeah well if you want your heat working TODAY, it'll be $XXX, or you can just be cold!" When it's in the single digits with a snowstorm inbound, an unscrupulous repair guy would totally have you by the you-know-what's on that, and it'd probably even have worked. Anyway, they came back a couple days later, and that morning as I was moving stuff away from my furnace I noticed my water heater was ALSO leaking. (Bad things happen in threes, like they say.) So, what was just an AC and furnace install turned into an AC, furnace, and hot water heater. Jeremy and his two guys, Tony and Brandon, spent the whole day ripping out all my old and busted stuff and replacing it with new hotness. (Literal hotness, as, man, having a new furnace is nice and toasty.) Later that night, the PEX tube feeding the humidifier somehow popped off, which I was able to catch pretty quickly and turn off. I texted Jeremy at around 11:00 PM not really expecting any kind of response right away and instead was met with a profuse apology, offering to send a cleaning service (It's just a little water, it's fine!), and to have his guys come out first thing the following morning to fix it. Bright and early, Tony shows up again to make a couple tweaks, and aside from that minor bump in the road which was fixed practically immediately, everything went awesome. I can't wait to get my first gas bill to see how much of a difference a two-stage furnace and new water heater make (same goes for an electric bill and the AC). The price they quoted was good considering they install all name brand stuff between Trane, Honeywell, and Rheem, and any charges for labor were well worth it as everything looks so much neater and nicer than the mess I had in my basement before. They even moved my water heater for me to a much more sensible place, which is going to make refinishing (or, more accurately, *talking about* refinishing) my basement that much easier. Overall, great service from a great company staffed by great guys. They know their stuff too, ask Jeremy any random question about anything to do with HVAC stuff and he'll give you an answer that's so comprehensive it's incredible. HOPEFULLY with all this new stuff I don't see the dudes at Harmonic for a very long time (maybe for beers, not for furnaces!), but I'll definitely be recommending them to anyone who needs anything HVAC related done in the future. read more

The Harmonic team attempted to repair my 25 year old AC unit. In the end, the "band-aids" were ineffective so I needed a replacement. Liz, through the owner Jeremy, applied a majority portion of my attempted repair costs toward the new Armstrong unit which was great. Liz was great communicating timing, price, etc. The technicians (Brandon & Donny) were very professional and knowledgeable and did not rush the installation to ensure it was done right (took over 5 hours). They walked me through the new unit and it works great so far. Thanks Harmonic. read more

Great company. Everyone I interacted with was very professional, informative and was able to answer all my questions and concerns. Guys came in to install new HVAC system, they were very cautious and were maintaining all the necessary precautions amidst COVID situation. Would recommend to all of my friends and family. Thank you Harmonic. Bart T read more

Last year our central air stopped cooling. Another company said there's a leak, added freon and suggested we should change our whole system. Yesterday our ac stopped cooling again. Blessing in disguise that the other company wasn't available. I looked through yelp and found Harmonic with good reviews so I decided to try them. They sent Daniel. After checking our system, he found nothing wrong!! The only thing it needed was a new thermostat!! This company is honest, reliable and quick to respond. Ask for Daniel...he's an excellent technician!! read more

I had my a/c go out on the 1st 90° + day. I contacted several repair shops only to be greeted by answering machines. It was 3:45 in the afternoon and I was expecting that it would be at least the next day if not 2 until a tech could get to my cooling issues. I spoke with the nicest lady on the phone, Liz. She took down my number, said she would check with a tech to see how quick he could get to me. Liz called back in minutes and said a tech could be there by 4:00 PM. And within 8 minutes, the tech arrived. He made quick work of rectifying my needs and corrected the the problem in a flash. I was not charged overtime rate and was more than satisfied with Harmonics employees on their professionalism and kindness. Thank you Liz, Daniel and the whole crew @ Harmonic. read more

Came out within two hours on a Sunday when our furnace wouldn't ignite on a 9 degree day. In fact, we got callbacks from two different people within 10 minutes of calling. Fixed the problem quickly, showed us what the issue was and then double checked other possible causes to make sure there wasn't something else wrong. Will call again if we ever have a need. read more

Absolutely wonderful. Jeremy went above and beyond to hook us up quickly when our AC went out. Installation was quick, clean, and implemented with precision. I think their are cheaper options out there but you get what you pay for and something for my house that will be there for the next 15-25 years, it was money well spent. Liz and team were professional and had plenty of follow up to make sure we were ok, read more

Fast, friendly and affordable. Had Harmonic install a new dryer vent since my old vent was expelling into my garage causing everything to get soaking wet in the cooler/cold times of the year. I set everything up with Tony a couple weeks back. Brandon arrived today literally at the stroke of 8:00am, which Tony and I agreed upon. Brandon was professional, knowledgeable and fast. Job well done! read more

Had Harmonic replace my furnace and A/C last month. They gave me the best price and were very thorough in explaining / comparing new unit with other units available. I would recommend Harmonic to anyone looking for service and/or replacement of your furnace. read more

After researching for a good HVAC company, I found Harmonic HVAC on Yelp and couldn't be happier. Tony checked our house furnace and I immediately signed up for their Maintenance program, so our AC gets checked in Spring as well. I remember Jeremy and Tony from previous work they had done for my business years ago and was already impressed back then with their work. I recommend this company to everyone who is looking for a friendly and highly qualified technician who actually cares about their customers and the work he does. read more

Chances are you have stumbled upon Harmonic as we did because you are looking for an honest and skilled HVAC team that will provide competitive pricing. Through due diligence you will likely contact several highly rated companies, and come to find out that Harmonic is truly unique within the industry. Harmonic preformed a Trane A/C / Furnace Replacement (Models: XL80, XR13), and additionally installed an Aprilaire Humidifier we purchased from Amazon. Harmonic's pricing is outstanding. The Trane A/C / Furnace models are both highly rated energy efficient units. The craftsmanship of the install was top notch. However, what was truly surprising is the supreme customer service Harmonic provides. Owner Jeremy and team provide a level of satisfaction and integrity that is truly unrivaled. From start to finish every member of the team was polite and professional. Answering all of our questions, and providing detailed instructions about how our new systems function. We could not be more pleased with the job Jeremy and team did. read more

Fast, easy, accurate, knowledgeable, thorough and a fair rate. I highly recommend this company!

All interactions we have had with Harmonic have been very positive. From scheduling & communications with Liz on the phone to our latest service appointment with Daniel have been much better than previous companies we have used. Daniel was very professional, friendly & knowledgeable. He explained what he was doing & why, which helps the customer better understand maintenance of AC & heating. I highly recommend this company! Also, I will be trying some of the other services they offer that I was not aware of. read more

Harmonic has what I'm looking for when I'm hiring a contractor to come to work on my house, the three-P's. That's professional, prompt, and priced right. I had a job done for a motor on my furnace and he even found out the warranty covered part of the job, saving me some money. I would absolutely recommend this company to my fellow yelpers. read more

Coming this Summer to a Theater near your! In a world where no heating Air company can be trusted anymore, one company steps up to provide service and pricing to restore faith in humanity lol! Seriously, Jeremy and Tony are so good they deserve 6 stars... They are very professional and clean. They seem more like computer analyst then traditional heating guys. After having them service my home and rental unit, I would never call anyone else. read more

Brandon arrived on time, performed a furnace clean and check for me. He was very courteous, knowledgeable and clean. The reviews didn't lie. I would highly, highly recommend Harmonic. I signed up for the maintenance plan that's how impressed I was. This company won't disappoint. read more

Plenty of really in depth reviews already. I talked to a few different places but was most comfortable with Jeremy - very knowledgeable, great customer service, super responsive. I'm guessing I could have found someplace cheaper (though the pricing met or beat two other places I checked out) but I don't mind paying more for excellent service and someone who knows what they're really talking about. We had them put in a new furnace in our Naperville place and have been very happy. They've followed up regularly as well. Happy camper! read more

Harmonic deserves every great rating that they have received. After many consecutive days of over 90 degrees and many more to come, our AC gave out on Sunday. I called other companies on Monday, and Harmonic was able to come out within three hours. I called around and many companies could not get out for 1-2 days. After reviewing all the great ratings, I felt comfortable with our choice of calling Harmonic. Shawn was the technician who came out, and he was professional, efficient and explained all the repairs and costs involved. Pricing is reasonable, and Shawn was able to diagnosis and fix our AC issue within an hour and a half. I would not hesitate to recommend this company to anyone. read more

It's always weird having strangers in your house, esp when most of the time you have no idea what's going on so you kinda expect to be sold things you might not really need. This company really lives up to it's 5 star reviews on Yelp. Tony came out for a job that wasn't exactly what I thought I scheduled for. Long story short, he quickly assessed the AC system, told me it was not necessary in our case and it was also a more expensive job. He was just an easy going honest guy. He didn't push me to have the routine maintenance work done at all. Which I did end up doing anyways bc of how honest he was in the beginning. We will be replacing our whole system soon (which is a big expensive project) and we're going with Harmonic for sure! read more

I have since been able to use them and everything I said before still stands! What a great group of people - so far and so so honest! I am grateful to have them in my corner! read more
