    Love these trucks!
    Val S.

    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!

    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.

    See ya', old A/C! You will not be missed, I assure you!

    See all

We called 2 places before we called Dutchman on a Sunday after 5pm. They are the only ones that actually answered and called us back. By 6:30pm our furnace was fixed! I highly recommend them - great customer service, knowledge and caring!

I trusted that they 'd do the job and look for the leak to fix it properly given the amount of money paid. I did some research afterwards and realize that they simply inject the dye sealant package ($50 cost) to do a temporary cover up which highly likely I will see a leak soon. It is very disappointing. Here is the invoice showing how they charge for an hour work today. Charged $262.50 to inject the sealant, and charged refrigerant by $175 / lb. My AC is 6 years old. - Updated after talking to the owner of the company. The owner told me on the phone that it will cost me $2000 + if they are conducting the leak search . As of 10/03/2024. The AC has failed, less than 10 days they have "fixed " the leak. They absolutely deserve a 1-star review. It is a borderline scam company. Make sure you get a quote from them and have them explain what they do to your system before agreeing to allow them to do any job. Had another company came out and identify the leak at the condenser within 30 mins. It was obvious due to oil presents where it shouldn't . Dutchman fool their customers in my case. Learnt my lessons.

I sent a message via Yelp on a Sunday night and they immediately scheduled our oven troubleshooting for Monday afternoon. Their front office staff is incredibly responsive! George (technician) arrived timely and was very thorough. He explained things to me every step of the way. He is approaching this very methodically - ok, so it's not the igniter, let's look at the next link in the chain... I saw George called out by name in other Yelp reviews, and I understand why he comes so highly recommended! He called the manufacturer to discuss his findings, but the manufacturer tech team wasn't available. He let me know he would be calling them again in the morning and that he would reach out to me with an update. I've had plenty of negative or so-so experiences with other service technicians from other companies. This experience with George / Astera is so positive that I'm posting my review even before the service is completed. Astera will be getting first crack at all of my appliance and HVAC service calls going forward.
