Miller's Heating & Air Conditioning

This business consistently offers excellent heating and cooling services. They are extremely helpful, cordial, and informed.

Great experience with Oasis. Well priced. Had the awesome repair guy, would recommend him. He was very respectful to my house, shoes off and cleaned up, and explained everything to me in a way a non-ac/heating person could understand. He even figured out why my whole house humidifier was not working and fixed it. I'm not looking anywhere else from now on.

David was very polite and even took the time to meet my little pack of little pets. He fixed my air conditioning unit expeditiously and competently. I now have air conditioning!!! I highly recommend Miller's Heating & Air Conditioning. They went above and over to help me. Thank you so much for doing this remarkable job!!! Top notch!!

I have ms and needed air conditioning in the summer. Our unit had been breaking down in the hottest summer. I was miserable and scared for my health. Miller's came to the rescue and we got a new air conditioning unit that was better than our old one. The price came with and excellent warranty and maintenance service. They did such a good job, that if they cleaned houses I will hire them for the spot too!

Super fast estimate and install scheduled. Very knowledgeable and considerate installers. Got a new AC and humidifier done in about 3 hours. An all around great experience from beginning to end! Would highly recommend Miller's Heating & Air Conditioning!!

I just had my annual service call and was very pleased with the professionalism and knowledge of David, the service provider. I feel confident I made a good choice in purchasing my air conditioner/furnace from Miller's Heating & Air Conditioning. We enthusiastically recommend them to friends and everyone!!

When my nest quit operating, Greg knew just what to do. He had the parts he needed on hand, and my air conditioner was up and running in less than 20 minutes! I'd give him 6 stars if I could! He comes highly recommended from me.

Just moved into Vernon Hills and wanted to give business to local company and BUILD a relationship. They sent out a contractor who is not an employee. It was just for a checkup of my AC. He took off cover and said two parts should be replaced. NO TESTING EQUIPMENT WAS EVER USED. He said that will be $450. Wrote up the bill for $535. I asked for a warranty on work done. He said to call the owner. Called the owner 3 times and never returned my call. STAY AWAY FROM THESE GUYS.

David is a very professional and knowledgeable Service Consultant for Miller's Heating & Air Conditioning. He is punctual for his scheduled appointments. During his visit, he will perform a root cause analysis and provide a solution to a problematic situation. You can feel comfortable knowing that your problem will be affordable fixed.

Julius did warranty work on my A/C unit yesterday afternoon. The temperature outside was in the 90's yet he managed to stay upbeat and keep working. I appreciated his positive attitude and professionalism. He is a real asset to Miller's company
