At Guardian Heating & Cooling Service, we realize you wait a long time for the summer weather to arrive in Chicago, IL and surrounding areas. Unfortunately, higher temperatures often bring an excess of humidity. A clammy house encourages lower thermostat settings, putting a bigger demand on the air conditioner and draining your budget. There’s potential damage to home-furnishings and high humidity levels create the ideal environment for bacteria, mold, mildew, and all sorts of germs to flourish. Let’s improve the comfort, health, and efficiency of your home with the installation of a dehumidifier.

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.

Laurie E.

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.

Installing the best and servicing the rest!
