Great service from this company. The technician, Mark, took a detailed approach, explaining each step and teaching me about my HVAC system. Unfortunately, his unit installation revealed problems with the previous job, but he fixed it professionally. Satisfied customer experience overall.

Cardinal's team is top-notch - fast, knowledgeable, and reliable. Their technician, Jordan, stood out for his professionalism, intelligence, and friendly demeanor, making the experience extremely positive.

The reviewer's top choice for an HVAC company in Chicago is this one - it's professional, quick, trustworthy, dedicated, and fair-minded.

My AC unit stopped working and I needed someone to fix it fast, but as a single mom, I was worried about being ripped off with overpriced repairs. Luckily, Jordan and Bryan from Cardinal Heating and Cooling turned out to be the opposite - they were super knowledgeable, courteous, and got straight to the point. Their assessment of the issue was spot on and their suggestions were really helpful. I'm thrilled with the repair and can confidently say I'll be calling them again in a heartbeat - they've earned my loyalty and respect.

Chuck was professional and friendly. His team of installers were also top-notch - polite, competent, and clearly experts in their field. After multiple estimates, Cardinal truly exceeded expectations throughout the entire process. We're very glad we chose them.

We hired Cardinal for our home renovation and subsequent furnace replacement. The team was outstanding, delivering top-notch service. Notably, they included the completed rebate form in their follow-up. Their exceptional work earned our trust and exceeded expectations.

They did a great job, were prompt and efficient. Called them in the afternoon and had someone show up early next morning. The technician was knowledgeable and fixed the problem right away. Great value for honest workmanship.

I bought an American Standard top-of-the-line furnace and matching AC unit from this company. The price was fair, but what really impressed me was the comprehensive installation - they upgraded the ductwork too, which boosted airflow in both directions. This business is excellent, with outstanding service and genuinely caring staff who run like a family-owned concern. What sets them apart is their commitment to integrity, a rare quality in this industry.

I woke up on January 5th to a dead furnace, with no heat in my home. Luckily, I called Cardinal Heating and they sent an emergency technician promptly. They fit me in mid-morning and fixed the issue without any fuss. Their quick response and skilled work are greatly appreciated - it's reassuring to know help is just around the corner when you need it most.

We've been using Cardinal's services for heating and AC maintenance for several years, always satisfied. Easy to get in touch with them. Quick response times. Nice guys who show up on time. Leave the place tidy. Use good quality stuff. Highly recommended.

These guys are hands down the smartest HVAC team I've dealt with. They genuinely care about getting it right, prioritizing comfort above all else. After comparing them to two other companies, I'm convinced that their work surpassed the rest - highly recommended.

They did a great job - on time, reliable, and at a reasonable cost. Installation was flawless, except I wish they'd been here sooner for other maintenance I required. Overall, very satisfied with their service, so I'd definitely recommend them to others.

Cardinal Heating and Cooling truly excels in customer service. They consistently show up on schedule, efficiently diagnose issues, and complete repairs promptly. The staff is professional and respectful, leaving the property tidy afterwards. Their commitment to quality ensures long-term satisfaction with no further assistance needed.

Chuck and his crew recently completed a new installation for an addition and replaced the original house, while also reworking the ductwork. They're excellent to deal with and thoroughly trustworthy. The pricing is spot on every time. I wouldn't hesitate to use them again or recommend them. Their office staff, particularly Kathy, is highly organized, responsive, and incredibly helpful.

This company is top-notch. The staff are highly trained, which shows they truly care about getting the job done right. Their work speaks for itself - excellent service from start to finish. I'd definitely choose them again.

A colleague recommended Cardinal to me, and I'm glad they did. The team was highly responsive, particularly Jordan, who was kind and professional throughout our interactions. They responded quickly to my initial inquiry, arriving at my address within a few hours of my call. Their service rates and parts were reasonable. Jordan took the time to explain his findings and presented a solution along with pricing. I'm confident in their services and will definitely be using them again in the future - I'll also be recommending Cardinal to others.

We've relied on Cardinal for all our heating and cooling needs over five years now. They're transparent about their pricing - you get what they quote you. We've had to schedule calls on weekends, which can be a pain, but the technician always shows up within an hour. When he does, he's polite and professional. That reliability and straightforwardness is why we keep coming back.

Cardinal was top-notch to deal with. They offered a fair price and quality product. Ed pointed out issues with previous installations and corrected them, keeping us informed about the start time. The entire crew was courteous and efficient. Their cleanup left the site spotless. I highly recommend Cardinal for any heating or cooling needs; their professionalism and attention to detail make them stand out.

They initially came across as friendly and professional, but the steep pricing and attitude of some younger staff members left a sour taste. The presence of older workers was brief, only to be replaced by a young teenager on site - it seemed suspiciously early for them to start working construction. Given the inflated prices and questionable work environment, I'd look elsewhere for better value and professionalism. The company's glowing reviews from friends and family in their faith community don't offset this experience; I'm sharing my honest feedback after being asked for a Google review.

Cardinal Heating and Cooling is a standout company that consistently delivers exceptional service. Our experience with them this past year has been nothing short of impressive, from prompt responses to every call to their professionalism and affordability. Kathy always answers my calls quickly and keeps me informed about the status of parts ordered, ensuring minimal disruption to our schedule. What impressed me most was their ability to source hard-to-find replacement parts for our wine cellar unit - a rare feat among service providers.

Cardinal HVAC is the top choice without a doubt. Avoid other companies - they can't hold a candle to them. Not only are their technicians incredibly professional and deliver superb work, but they're also genuinely honest and pleasant to deal with. For instance, when I had an AC issue, multiple firms quoted me upwards of $3000 for repairs. Cardinal came out and estimated the cost at a few hundred bucks - it was a fraction of what others were proposing! The unit has been running flawlessly for two years now and I'm grateful for their transparency. They've earned my loyalty forever with that level of integrity.
