Replace Your Existing Equipment

Let’s face it. There are a lot of homes in the Chicagoland and Northwest Indiana area that simply aren’t comfortable. Most use more energy to heat and cool than they should. Many have terrible indoor air quality. Why? Because too many heating and cooling systems have been thrown together and too many corners have been cut.  

Illiana Heating is reversing this trend of low quality installations. How?  By following a proven system.

It all starts with the design. First we inspect your existing system including the ever-important duct-work. We then measure and inspect your home, allowing us to complete a load calculation which tells us what size equipment your home needs. It also gives us the ability to make recommendations to improve the energy footprint of your home. After completing our load calculation and energy survey, we’ll provide you with several options. We’ll work with you to find a solution – a solution that makes you comfortable with us as a company and with the products we provide.

The most important day in the life of a heating and cooling system is the day that it is installed. You can buy the most efficient, fanciest system in the world, but if it is installed poorly, it will never work the way it is supposed to. Then you’ve just wasted your money. We are confident that an Illiana Heating installed heating and cooling system will look better, work better, and use less energy than the same system installed by any other company in the area. We have this confidence because of the high standards we have for our Installation Team. We are so confident in fact, that we provide a written, money back guarantee that you will be satisfied.
