HVAC reviews in Chicago, Illinois

Danny and his team did a fantastic job installing two new furnaces and a zoning system for our home. The installation was quite complex, which led to some initial issues, but the team wasn't afraid to come back multiple times until everything was working properly for us. We're now enjoying much greater comfort than before, all at a very reasonable price. We got quotes from several other companies, but Danny's clear explanations and creative ideas during our estimate walkthrough won us over - he also offered the best deal. I highly recommend Danny and his team from Oasis; they truly delivered an excellent experience.

We needed a whole new AC system ASAP for an apartment with tenants. The timing couldn't have been worse - it hit during a heat wave, making every minute count. I called around 10/11pm on Tuesday and Yola guided me through a simple troubleshooting process that I could do myself (no extra charge). She advised calling back the next day if it didn't work, which unfortunately it did. However, they managed to send someone over the same day, despite the chaos caused by the heat wave. Within 48 hours of reporting the issue, we had a brand new system installed that works better than our old one. Kudos for getting it done quickly and efficiently - thanks!

I needed assistance with a heating issue on short notice, and Global Heating and Cooling came through immediately. They had all necessary gear to access the roof and identify the problem, providing a transparent estimate right away. On July 5th, they got the job done quickly, giving my home some much-needed relief from the heat. The team was incredibly professional, friendly, and courteous throughout the process - even from initial contact with the operator and dispatcher to the installers themselves. I'm thoroughly impressed with their service.

They did excellent work and I'd highly endorse them.

This company is hands down the best team I've worked with in Chicago's heating and cooling scene over my 15 years as a property owner. They keep it straightforward, explaining what needs to be done upfront. Their work is on schedule and at a reasonable cost. When my heated floors stopped working, they were quick to respond and made repairs without charging extra - impressive customer service. If you need any heating or cooling work done, I highly recommend giving Global a shot.

Still pleased after being with this company for years, I recently had my heating system serviced as the season changes. The importance of regular maintenance cannot be overstated - neglecting it can lead to serious problems like carbon monoxide leaks. I've been using their services for a couple of years now, initially for installations and now for routine upkeep on both my furnace and AC. Their technicians are always clear about issues and options, making them reliable and trustworthy.

Paul and his team were extremely patient and professional when addressing our sudden air conditioning issue. They arrived on the same day I called to schedule an appointment, making it easy to work with them as we discussed the problem. The technician took the time to thoroughly investigate and identify the root cause of the issue - a faulty compressor on our rooftop unit. He then ran tests on our systems, provided potential solutions using parts he had on hand, and offered clear advice on how to maintain our air conditioning in the future, highlighting any areas that might require extra attention.

I recently had a frustrating experience with another service provider, but this company got it right from the start. After doing my own research, I found that they shared my diagnosis and fixed the issue without any extra charges. They did the job efficiently and at a reasonable cost - now my furnace is working properly again.

We've had a consistently excellent experience with Global Heating & Cooling. They're quick to respond and flexible with scheduling, even on short notice. Their team member, Paul, has helped us multiple times with an older AC unit and is knowledgeable and thorough in his work. We feel confident that we're in good hands with them, which is why we plan to continue using their services for our HVAC needs.

I've had a fantastic experience with this company. After hearing great things about their professionalism on NextDoor, I decided to give them a shot. They arrived promptly within two hours, despite it being a busy day. The service was top-notch - they were extremely helpful, courteous, and efficient. It's clear that both Mike and Paul are experts in what they do. I felt confident in their abilities, especially given the pandemic situation. What really impressed me was the attention to detail, including wearing masks while working in my home.

Here's the rewritten review:

Patric did a great job with my furnace maintenance. He arrived early and showed respect by removing his shoes before entering. He thoroughly explained what he was doing beforehand and after completing the task, making sure I understood everything. During our last call for minor maintenance, Patric made a reasonable recommendation without trying to upsell me. What impressed me most was his honesty - he didn't add any extra charges to my bill. His professionalism and service are top-notch, which is why I'll be sticking with Global Heating from now on.

I've finally found a reliable home services team that exceeds expectations. Unlike my previous experience with another provider who seems to have vanished, I'm thrilled to have these professionals on board.

They handled an unexpected furnace issue with remarkable efficiency, completing the installation on impressively short notice. What's more impressive is their use of technology to streamline communication and appointments – you receive texts when they're on the way, emails with invoices, and even online payment options.

Their professionalism has earned me a loyal customer for life.

Mike did a great job. We had a major issue with our AC - it stopped working overnight and our house was sweltering. He arrived promptly at 8:15am after we called him at 7:30am. It turned out our thermostat was faulty and he temporarily fixed the wiring to get cooling back on. He suggested we replace it, noting that installation is straightforward and saving money by doing it yourself. I ended up buying a Nest and Mike even provided support via text as I installed it. Overall, I'd highly recommend Mike's services.

I've been working with Global since buying my condo and their professionalism shines through in every aspect. They're highly organized, sending out confirmation notifications before their technicians arrive, ensuring a smooth process. Scheduling an appointment is always quick, often on the same day. It seems they assign specific techs to addresses, so we consistently get Paul, who explains what he's doing and offers insightful suggestions for future maintenance. Their digital billing system provides convenient e-mail receipts and invoices. They've also done annual A/C and furnace checks and replaced our water heater - I'll definitely be reaching out when it's time for a new furnace.

I was thoroughly pleased with my experience. I needed a new thermostat installed over the weekend and called them promptly. A call-back arrived within an hour, and an appointment was set for Monday morning. The technician showed up right on time, was courteous and professional throughout, answering all my queries. The entire job took less than 30 minutes to complete. I'm extremely satisfied – they truly exceeded expectations.

The technician, Patrick, was respectful and efficient. He left the workspace tidy. Kamil, the owner, is approachable and professional. He offered a fair price for the service.

I'm extremely satisfied with the service I received from Global. After a handyman installed a Nest thermostat, my AC stopped working effectively. The team responded promptly, arriving just a few hours after I called. Mark and Mike were courteous, skilled, and knowledgeable technicians who handled the job efficiently. Due to their expertise, I opted to replace my 18-year-old system instead of repairing it. Pauly did an outstanding installation job, completing the work in under 5 hours with my home restored to its original condition. The new system is significantly quieter and more efficient – I'm thoroughly pleased with the result!

They provide top-notch, 24/7 support. Our experience with their warranty program through American Home Shield is positive. What sets them apart is they're not affiliated with the warranty company's services, so we opted to pay extra for exceptional service. The technician was reliable, knowledgeable, and courteous, keeping us informed about each task performed on-site. I'm thoroughly impressed and have since added their name to my list for future heating maintenance needs.

Mark arrived promptly after my call the next day. He explained that our old central air conditioner - having been in service for 29 years - needed to be replaced. We were impressed by his expertise and professionalism. The quote was very reasonable, and they got the job done the following day. The installation team left a great impression, being tidy and courteous. I don't usually give 5-star reviews, but this team truly justified it. Highly recommend Global Heating and Cooling; they're the best!

Kamil did an excellent job fixing my air con. He not only fixed the system but also explained how it works - both the blower/furnace and compressor. I'd highly recommend Global Heating for any HVAC issues.

I got a great recommendation from a friend who used Global for their aircon service and it paid off - they're top-notch. Their technician, Mike, was particularly impressive. He walked me through the diagnosis process in a clear and concise way which helped me understand what he was doing. His expertise led him straight to the root of the problem and he fixed it without fuss. I'm sold on their service and will definitely come back if needed - just ask for Mike!
