Best Heating & Air Conditioning / HVAC In Libertyville

“Allied Air Conditioning has been our go to company for our heating and air conditioning for more than 20 Years. They are efficient, polite, and always clean up after themselves. I whole heartedly recommend them.“

“I would recommend Legendary Service to anyone. Sean and Colin were great. Quick response and install times. We needed to replace our furnace and AC, and went with a heat pump. They educated us on different units and compared them. Recommended a Uv light and we also added on a 4” filter which have helped with dust in our home. No BS upfront company and you can tell the employees know what they are doing. Highly recommend them.“

“I had a big project for them, repiping my 87 year old boiler system, and they did a great job exceeding my expectations! I highly recommend them.“

“Woke up to a cold house, so I knew my heater was on the fritz :-( I called TopTec at 7 AM, and they had someone over by 10 AM! :-) My technician, Jordan, was great! He solved the problem quickly, explained the issue, and even went out of his way to explain my humidifier, which I had always been curious about. Jordan was exactly the kind of friendly and knowledgeable technician who I was hoping would help us. Very happy I called TopTec.“

“Thank you for your and your team's professionalism and customer service.

The furnace install was above and beyond expectations.

The new unit is quiet and feels warmer already.

My wife and I appreciated the prompt/honest and thoughtful response to our heating issue.

We will recommend Thornton Heating for anyone needing HVAC care.“

“Carlos and his team were very attentive to our needs.
Very clean and explained everything that he was doing and what he found.
Everything was put back perfectly.
Will Definitely use again and will refer him and the company.
Thanks again“
