Ductless mini- and multi-split systems provide nearly limitless opportunities. These compact yet powerful units accommodate tight installation spaces yet handle one or multiple rooms of any size or style. There’s no ductwork taking up space or requiring the gutting of walls and ceilings. Streamlined indoor air handlers mount up high on the wall and link to a single, quiet, and unobtrusive outdoor compressor, requiring nothing more than a small hole and access to electricity. Call the professionals from Guardian Heating & Cooling Service for installation in Chicago, IL and surrounding areas, and we’ll most likely have your system up and running that same day.

What our clients are saying

Mo W.

Guardian is a top notch company and John is one of the most outstanding technicians I’ve ever worked with. He’s a trustworthy contractor who explains potential issues as he finds them, and breaks down the process of replacement so that anyone can understand it. I own 12 HVAC systems and I’ve seen more than my share of maintenance. I’ve used Guardian for years and these guys are simply the best.

Keith B.

Have used Guardian for years. Recently had a new furnace and central air installed and I couldn’t be happier. I really trust them because the workers are always extremely knowledgeable, good problem solvers, and they explain everything in terms I can understand. The guys are always very nice, and respectful, also. Highly recommend Guardian Heating & Cooling.

Just had another great maintenance visit to prepare my old A/C units (2) for the summer. John was thorough and informative. Great job.

I have used Guardian Heating for over 15 years. And my original Rheem furnaces(zoned heat) are still running! I use their maintenance contracts to get reminders, advance scheduling and discounts on annual furnace and A/C checkups/cleaning. They are always quick to respond to a service request. I highly recommend them.
