Indoor Air Quality, Humidifier Maintenance & HumidifierWilmette, IL, Park Ridge, IL, Chicago, IL, Skokie, IL, Morton Grove, IL & Lincoln Park, IL

In Chicago, IL and surrounding areas, overly dry air is a problem for the majority of the year. Cold weather combined with the non-stop operation of the heating system adds up to insufficient humidity and the associated consequences. Static shock, chapped lips, frizzy hair, sore throat, sneezing, coughing, headaches, and damage to home furnishings are just the start. When humidity drops below the recommended levels, the air feels chilly, prompting higher thermostat settings. The increased demand on the heating system results in greater strain on your wallet.

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!
