HVAC reviews in Carol Stream, Illinois

Quick and reliable service. Great price and very professional on install day. Did an amazing job letting us know the different types of units and what would be best for our home. Could not be happier!!

Start to finish these guys were absolute professionals. No surprises, very quick work, and well done. Absolutely recommend them.

I was so impressed with the two technicians who came to fix our a/c/heating unit. It wasn't just that they fixed the immediate problem; they proactively fixed an issue that could arise later. And the explanations given as to what the problems were and what they were doing to fix them were so clear. I will definitely call AllStar again if another issue arises!

AllStar Heating & Cooling Corp. impressed me with knowledgeable, polite, and professional service. My service person, Eric was especially remarkable. He was very knowledgeable about my heating & cooling units. He did a very thorough analysis and cleaning. He was also very friendly and professional.
I very much appreciated his expertise

Our living room finally feels comfortable again after their expert touch on our vents. In just under an hour, they transformed our airflow, making the whole house noticeably fresher. Highly recommend!

When the cool air finally flowed again, relief spread in the room. The technician was prompt and fixed the issue efficiently.

Because Google don't have 0 star. I can write a long review but I want to forget about this company. Terrible service and even worse customer service. I trusted reviews and I'm highly disappointed. Not recommend!

Prompt response, friendly, professional, and will advise on what you need and not trying to make a quick buck. I will definitely use them again.

One of the most honest, reliable, reasonable and great HVAC guy we know.

By far the best contractor I’ve worked with in any trade. Never mind the fact that he’s knowledgeable and skilled, but more than anything, a genuine and honest person.

I've used them a few times and Justin has always been super nice, very knowledgeable, and helpful. He's very willing to explain what the problem is and makes sure you're happy. Very reasonably priced and very fair.

10/10- Absolutely recommend. Extremely polite and funny. Very responsive and gives a fantastic rate. He has completed work on my house, as well as several of my neighbors! You should save time reading reviews and call him today!!

Justin and his team perform the best HVAC services in the area. He has helped fixed many issues at my house and friends and family's houses over the years. Most importantly, these services are provided at a more than affordable price! I wouldn't recommend any other company but Moran & Sons for HVAC services!

Incredibly professional and timely company with customer satisfaction at its core values.
Extremely friendly and diligent workers.
Sincerely appreciate their efficiency and expertise.
Will most definitely be recommending Moran & Sons to everyone I know; can not commend them greater.

Efficient dismantlement; professionalism exceeded all expectations.

Professional, honest, hysterical and genuine, nothing more you can ask for. I will continue to use Moran & Sons for any future issue thanks to the wonderful experience I’ve had with the owner, Justin. Couldn’t recommend this company any more.

We are SO pleased with Justin and Liam! We were referred by friends in the area. They are professional and kind and easy to work with. Our house has had poor air quality for a long time among other HVAC issues and they have been invested in making things right for us and our young child. We will continue to use them for all of our HVAC needs in the future. HIGHLY recommend.

From start to finish, the team was professional and attentive, ensuring our ventilated ceiling was flawlessly installed in just under four hours. The difference in air quality is amazing!

I have been with Shamrock for at least 10 years. They have helped me maintain the AC and heating in a professional manner. Those who come out are professional and will explain the process and any results they encountered positive /negative while performing there heat/air check . Definitely recommend them .

The guys were professional and clean friendly and kept me informed of the progress it was a complete system replacement

I have personally been a customer of Shamrock for many years. I have always been happy.
My 94 yr old mother needed a new furnace and a/c. They made it so easy, fast, efficient and the price was very reasonable.
Thank you to their wonderful crew. Another plus, they clean up well after themselves. 10 stars
