HVAC reviews in Chicago, Illinois

The new AC installation was completed in record time. Paul and his team worked efficiently and knew their stuff. I called on a Friday morning, got an estimate for the following day, and they had it done by Monday. The invoice was clear and easily paid online. Overall, it was a very positive experience.

Works seamlessly with Global Heating. No-frills pricing that competes effectively. The team delivered high-quality, efficient service. A new Lennox unit was installed on the rooftop without issue. You can book with confidence here.

Had Global arrived for their annual visit and recently replaced our AC unit. They showed up promptly, were courteous and assisted us efficiently. A few days later, I had a follow-up question and they not only addressed it but sent someone to double-check the work, which was impressive.

It's never pleasant having your HVAC serviced, but at least this made the experience tolerable.

This company is a lifesaver. The snowstorm that hit Chicago left me without heat, but they stepped up to the plate. I called them and within an hour, technician Patrick arrived at my doorstep. He quickly diagnosed the issue with my furnace and had it fixed in under an hour. Given the freezing temps, I was worried about going days without heat, but it's been working flawlessly since then. Their service is top-notch and their team is very reliable.

This technician arrived at my condo remarkably quickly, given the early hour and holiday. The service fee was surprisingly affordable compared to what I've seen elsewhere. Mike proved himself to be very helpful and flexible, especially on a Sunday when many services are closed. He efficiently diagnosed the issue with my AC and got it up and running right away. His professionalism and courtesy earned him a spot at the top of my list for future needs, and I won't hesitate to call again.

We were fortunate to have encountered these guys. They made a big difference for us, particularly Paul, who went above and beyond. After shopping around to various places, they showed up much faster than anyone else and got the job done efficiently. The entire A/C installation was completed in just 3-4 hours - an incredibly short timeframe. I'd wholeheartedly endorse Global Heating and Cooling and would definitely recommend working with Paul and his team; they're top-notch!

Paul and his colleague did a fantastic job at our center (Dreamers Academy). They were understanding as we had some difficulties accessing the roof, but quickly pinpointed the issue and resolved it efficiently. Now we have AC up and running again. Their scheduling was incredibly quick, unlike another company. The price was very competitive. We're extremely pleased with the overall service. Thanks for a great experience from start to finish!

Terrible experience with this company. The quote for a minor issue was outrageous - they wanted $500 for 15 minutes of work. They didn't even fix the problem, forcing me to call them back to try and get it resolved. This time, I was charged another $120. Despite multiple attempts to resolve the issue, my AC unit remains broken and I'm now seeking help from a different company.

Patrick and David were excellent. They quickly identified the root cause of our heating problem and resolved it on the same day at a fair price. I'd highly recommend this company - their service was top-notch and the work quality was superb, even on one of the coldest days so far this winter. As a parent to a 1-year-old, having reliable heating is a top priority, and this team exceeded our expectations. It was a great decision to choose them.

I've had mixed experiences with this company, especially with their mini-split units. When I was having issues with my unit, it took forever to get someone to come out. Despite being busy in October, I was left with no phone calls or responses after leaving multiple messages. However, the positive reviews led me to request a quote before proceeding.

After three days of calling, I finally managed to schedule an appointment. While they did provide text updates on the scheduled time, that's about where the professionalism ended. The actual service call was a letdown – the technician arrived, spent 15 minutes setting up, and couldn't proceed due to an issue with the unit remote control. He told me it would require calling LG directly for a new remote specific to my system's serial number, which was clearly a fabrication.

The most infuriating part was when he informed me there was a $120 charge just to come out, without mentioning it before booking. I asked if he could at least provide a quote for a new system installation, and he promised one would be sent by the end of the day. However, that never happened. When I tried calling again, I went straight to their voicemail.

I've been left with no choice but to move on to another company. It's disappointing that this company can't provide reliable service, especially for specialized units like mini-splits.

I've had two instances of Kamile addressing problems with my water heater, which were originally installed incorrectly. Each visit was quick, complete, and their work was excellent. I'd highly recommend their services without hesitation.

Patrick and his brother were excellent. Very tidy and respectful. Their work speaks for itself - that's why Global has such a great reputation.

This team delivered when we needed them most, responding promptly to an HVAC emergency at our home. The technician not only addressed the main issue but also caught a secondary problem with the exhaust pipe and fixed it without additional charge.

A billing mistake due to miscommunication between the service tech and back office led to an overpayment, which was rectified immediately when they called us, refunding the excess within 20 minutes of their own accord. Their customer service was impressive.

We worked with Patrick, who was professional, reliable, and easy to deal with. We'll definitely recommend them and return for our future needs.

I'm extremely thankful for Kamil at Global Heating and Cooling, who arrived the next day, Feb. 16, 2021, to replace my broken boiler in a four-unit building. The risk of extreme cold temperatures below zero posed a significant threat to my tenants and family's safety. Thankfully, Kamil and his team kept their promise and worked late hours until the job was done. I'm grateful for their professionalism and commitment. They exceeded my expectations and I wouldn't hesitate to call them again.

Vlad exceeded our expectations in every way. His prompt response to our AC breakdown the night before a big party saved us. He arrived just five hours after we called at 5am and got everything fixed. Vlad is kind, efficient, and displays excellent professionalism - we've found our go-to guy!

We overpaid for our AC's capacitor replacement, which cost $380 plus a service call fee. The technician didn't explain the diagnosis until after he'd fixed it. Apparently, they only revealed the problem to cover their installation claim. This isn't an isolated issue - others have complained about this too. Unless you want to pay more and not get clear explanations, consider getting quotes from other companies.

I've had my heating and cooling systems replaced by Global Heating and Cooling several years ago. The team has consistently provided excellent, hassle-free service whenever I've needed it. They're always prompt to respond to my requests and fix the issue efficiently under warranty. Mike is particularly impressive - he's a pleasure to deal with and sets the standard for customer service. Given my experience, I wholeheartedly endorse their work and would recommend them to anyone in need of reliable heating and cooling solutions.

The customer service from this company fell short of expectations, despite the technicians being pleasant and professional. The problem lies in management's handling of situations, where employees are forced to follow strict protocols without flexibility or consideration for customers' concerns.

A significant issue is the phone operator's behavior, who consistently cut off customers mid-sentence, making it impossible to ask questions or clarify costs. This abruptness was accompanied by demands to stay on the line and pay immediately, with no time for thought or research on the proposed charges. It's unreasonable to expect customers to agree without understanding the breakdown of labor and material costs.

The quoted price of $800 for a capacitor and refrigerant replacement was suspiciously high, considering online estimates of the materials' cost were under $100. When inquiring about labor vs. material costs, the operator refused to provide transparency, insisting on immediate payment with no room for research or verification.

This company's business model appears to prioritize profit over customer understanding and fairness. Charging arbitrary amounts without clear explanations is unacceptable, especially when customers are already vulnerable due to broken appliances during peak summer months.

Unless thoroughly researched and understood, it's best to avoid this company altogether. Take the time to investigate costs and potential repairs before agreeing on any services. Be prepared to push back if prices seem unreasonable.

The company's response did little to address these concerns, with management failing to intervene or offer alternative solutions. In fact, another company provided a second opinion and repair at a significantly lower cost ($250 for refrigerant refill), revealing discrepancies in Global's assessment of the situation.

Avoid Global Heating and Cooling at all costs; there are better options available that prioritize customer satisfaction and transparency.

Kamil and Patrick did a great job replacing my AC unit after it failed. Their service was prompt and efficient, with no unnecessary delays. The work was done professionally, and the price was reasonable. I also appreciated their response to urgent heating issues in our new home - they arrived quickly and prioritized getting the heat back on as soon as possible. Despite the urgency of the situation, everything was resolved promptly and effectively.

Here's a rewritten version of the review:

I recently worked with Global Heating & Cooling LLC on a renovation project for an older historic home in Lake View, Chicago. The goal was to find a heating and cooling solution that would complement the space without altering its unique character.

Global Heating & Cooling LLC delivered by installing a high-velocity system tailored to our client's needs. Their team showed impressive expertise throughout the process, ensuring every aspect was considered and integrated smoothly with the home's design.

As both the client and I, as the general contractor, were thrilled with the result, we can attest to their professionalism and work quality. The installation was prompt, efficient, and of exceptional standards. It's a pleasure to collaborate with a team like Global Heating & Cooling LLC who possess in-depth knowledge of projects like this and consistently exceed expectations.

I strongly endorse Global Heating & Cooling LLC for anyone seeking reliable and innovative HVAC solutions. Their commitment to customer satisfaction and craftsmanship is truly noteworthy!

We were blown away by Patrick's furnace replacement service - it was a highly complex installation due to the old furnace being built into a tight space with ducting on one side, wall on the other, and a narrow doorway in front. Our first contractor thought we'd need to demolish the drywall, swap furnaces, and fix the wall, while the second suggested taking out and rebuilding the left-hand ductwork. Patrick cleverly dismantled the old furnace to remove it, avoiding those destructive options. It's surprising no one else thought of that. We're extremely pleased with the outcome, especially since our AC replacement was a breeze by comparison. Great work from both Patrick and his colleague who came out yesterday - we highly recommend this service.
