HVAC reviews in Chicago, Illinois

Guardian's emergency service answered on a Sunday night and dispatched a technician the following day. The technician showed up promptly, was courteous, and knowledgeable. They provided clear explanations and handled our situation professionally. The entire process was efficient and respectful, especially considering it happened on short notice.

We were in the middle of a heat wave when our 20-year-old AC gave up on us. Time for a new one, so we shopped around for quotes. Guardian stood out as the best value-wise and most responsive.

Tassos showed up on Saturday to assess the situation, no fuss or frills. He was upfront about the pros and cons of different options, sharing his own experience with each product. By Thursday, Jerry and Juan were swapping out our old furnace for a shiny new unit - they did an excellent job, were friendly and professional, and left everything spick and span.

The whole process felt smooth, thanks to the team's promptness and genuine concern. If you're stuck with a busted AC and need speedy, trustworthy service from folks who actually care, Guardian is your best bet.

They installed our heating system two years ago, but we've had zero reliability since then. The unit's always on and off, leaving us with no hot water for days at a time. When the building management tries to reach them, they never answer their phones. Now, the heat's gone again, and their excuses are starting to get old. Don't bother trusting this company if you need consistent heat in your home.

Their lack of follow-through is appalling. The fact that we still don't have hot water speaks volumes about their incompetence. It's clear they're more interested in making excuses than fixing the problem.

The technicians were top-notch - professional, courteous, and clear in their explanations. They provided a reasonable quote upfront and worked efficiently. Plus, they left the area spotless. Overall, we're thoroughly pleased with our new boiler installation.

Highly recommended. We hired them for furnace installations in 2020 and were pleasantly surprised by the smooth process - unlike some other quotes which required major renovations. Their ongoing maintenance is also on point, no issues so far. Thanks again.

We called multiple companies when our AC gave out, but Guardian was the only one who took care of the problem properly. Miguel handled our inquiries and tracked down a custom unit from Canada - no quick fix here. Brian's crew did a great job installing it, explaining how everything works, and leaving the place tidy. It was clear they wanted to do things right. We're impressed with Guardian's attention to detail and professionalism.

Chris, Martin, Erik, and Gary got the job done quickly and arrived on schedule. The service was top-notch and the workspace left spotless afterwards. Chris made sure everything met my standards and answered my queries confidently. Overall, I'm extremely satisfied with their work. Guardian Heating and Cooling is highly recommended - they genuinely deliver excellent results.

Flame sensor malfunctioned unexpectedly just before midnight on NYE. Quick response and repair by 9pm avoided major hassle, saving us from significant stress. We're very grateful for the swift service.

We've had a great experience with Gabriel from Guardian, he's knowledgeable, friendly, and meticulous in his approach. His dedication to delivering top-notch service is clear - it's evident that quality workmanship means everything to him. We've been loyal customers for years, feeling like we have partners who genuinely care about our building just as much as we do.

Martin and Brian delivered top-notch service. Highly competent professionals who worked seamlessly as a cohesive unit. The installation process was efficient and meticulous, with clear explanations provided for the new boiler's features. Their attention to detail was evident in the thorough cleaning, which impressed us greatly.

First-time user here - met Darwin, who's super nice and keeps you in the loop. So far, so great, thanks for the service. Will likely use them again.

Lisandro and his team were prompt and efficient. They quickly responded to our emergency situation with the help of a flooded HVAC unit, getting it back online while we were away. We're grateful for their timely assistance.

The technician, Darwin, came across as genuinely friendly. He took the time to demonstrate each step and offered alternatives that could help reduce costs. His knowledge of the work was evident, and he didn't appear rushed, which is a testament to his professionalism.

One year since the new furnace installation everything's working fine. Maintenance on three more furnaces this winter didn't raise any issues. Prices were reasonable, which is good to know as a cost-effective choice. Also appreciate their local approach and customer service.

The technician who came to our home was exceptional from start to finish. He took the time to thoroughly explain the necessary repairs, ensuring we understood everything and weren't surprised by any costs. He worked hard to find more affordable solutions for fixing our AC unit, which I greatly appreciated.

What impressed me most about this technician was his genuine concern for our situation. The heatwave was particularly tough, and he recognized the urgency of the issue. Despite a long day, he arrived with enthusiasm and showed empathy towards my frustration. His dedication to getting the job done right was evident throughout.

The company managed to fit us into their schedule on an emergency call, which I found incredibly helpful. The technician returned the next day with the necessary parts and completed the complex repair efficiently and professionally. He made a difficult situation much more manageable.

This technician is outstanding - highly skilled, kind, and clearly passionate about his work. I wholeheartedly recommend him and the Guardian team. This company genuinely cares about its customers and takes pride in doing things correctly.

Guardian did a great job installing and maintaining our furnace and heat pump - excellent customer service and technical knowledge.

Darwin did a great job with maintenance on my furnace - very professional and communicative throughout. He kept me in the loop about what he was doing, why, and provided helpful tips for upkeep. His expertise is top-notch and I'd definitely recommend him to others. Thanks for the service!

I called Guardian on a Friday morning when my air conditioning suddenly stopped cooling me down. Munro got back to me 30 minutes after I reported the issue, and he showed up just 15 minutes later. The repairman spent two hours fixing the problem using spare parts that were under warranty. He was top-notch - extremely professional, efficient, and personable. He took the time to explain what he was doing, getting into fine details. After finishing the job, he offered some advice on how to keep my AC running smoothly in the future.

Our technician, Bert, was a standout - friendly, knowledgeable, and extremely professional. He quickly identified the problem and presented us with viable solutions. The service was outstanding, thanks in large part to his expertise.

Gabriel stands out as one of the top technicians we've worked with at Guardian. He's knowledgeable, professional, and has a personal touch that makes him easy to like. His explanations were clear and detailed about our furnace issues. We'll definitely be calling him again.

Paid $150 for a 15-minute diagnostic that consisted of little more than a chat, with no tools used. A week later, I still haven't received a quote for the basic repair work done during this visit. Despite being asked to leave feedback after receiving an email, all they provided was a receipt for the fee and not the actual cost for the job. The technician was friendly.
