Best Heating & Air Conditioning / HVAC In Libertyville

“Ken and Juan did a great job. They are welcome back to our house anytime. Thanks for their service. Happy Holidays to all.“

“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.“

“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.“
