About Us

At Assurance Heating & Air Conditioning, we’ve been working with customers since 1981 and know that there are certain things you want and expect from a reputable heating and air conditioning company.

We are your Cook & Lake County, IL Furnace, Heating & A/C Experts.

We know you want fast service. When your heating or AC goes out, it’s usually an emergency. That’s why we pride ourselves on speedy response times, same-day appointments and 24/7 emergency service.

We also know you want a heating and cooling contractor who will get the job done right the first time around. You don’t want to have to call an air conditioning company again and again just to get the kind of service you should have gotten on the first visit.

Whether you need a new installation, a system replacement, equipment maintenance or a simple heating or cooling system repair, we offer you professional service at a reasonable price. We know that if you’re happy with our work, you’ll refer others to our company, and that’s good for us. So we treat you as we would like to be treated.
