HVAC reviews in Chicago, Illinois

The technician showed exceptional attention to detail and professionalism, taking ownership of the installation process. He thoroughly checked the system to ensure proper function and water flow, demonstrating a high level of expertise. Overall, a positive experience that warrants further business with this company.

We had a furnace breakdown soon after Christmas, requiring emergency service. We called Delaware Commercial Heating And Air-Conditioning because they were recommended by my brother. Ben answered the call and arrived within an hour. He was very helpful, taking the time to thoroughly explain the issue and the solution to fix it, which greatly alleviated our stress.

I had a positive experience with Jeff from Delaware Commercial Heating & Cooling after he fixed my furnace. He was courteous and assisted me thoroughly. The job was completed promptly and efficiently. I'd consider hiring them again due to their good service and friendly demeanor.

We've had nothing but positive experiences with Delaware Commercial Heating And Air-Conditioning over our three years of service. Every technician we've encountered has been courteous, efficient, and genuinely helpful. Their professionalism shines through in every interaction, making us feel confident in their abilities. We're already looking forward to using them again in the future.

We're thoroughly satisfied with Delaware Commercial Heating And Air-Conditioning's services. The installation of our new A/C unit last year went smoothly thanks to a top-notch Service specialist. He ensured the job was completed promptly the following day. This year's annual service was equally impressive, showcasing professionalism, courtesy, and punctuality.

After researching six heating and air conditioning companies, I selected Delaware for their superior expertise. Their technician, Jeff, provided excellent guidance and support. The installation process was swift and spotless. Initial communication set the tone for a smooth experience. The installers arrived promptly and addressed all our queries. This company exceeded my expectations - a standout choice for those seeking reliable service.

This company exceeded expectations with top-notch customer service, regularly updated me on progress, and deployed an efficient technician who broke down complex tasks into easy-to-understand explanations - a huge thank you to the team, particularly Ian.

Excellent service from highly skilled professionals who clearly know their stuff.

Be cautious when purchasing from this company - their products are sold "as is," which means you're on your own if something goes wrong. When I bought a defective part, they refused to replace it with a new one, leaving me high and dry. A different supplier did the same part perfectly, proving their faulty quality control.

This company gets two things wrong: customer service and follow-through. Their demeanor is dismissive, and it's clear they're not interested in addressing concerns. The fact that I had to call multiple times before getting anywhere suggests a lack of effort on their part. What initially piqued my interest - the high recommendations - was completely lost due to poor first impressions.

I'm extremely satisfied with this company. We needed an inducer motor for our furnace on Thanksgiving Day due to a breakdown. Fortunately, they were closed but the staff called back quickly to accommodate us. What impressed me most was that Rangel personally installed the new motor in the part we brought along. His expertise is unparalleled, and I wholeheartedly endorse this business.

I got an appointment quickly and they fixed my AC on the same day. They made a long trip from Palos Park but arrived fast and provided friendly service. The technician explained the problem clearly, not just recommending a replacement unit. It's a great and honest company!

I recently had the misfortune of dealing with a company that failed to meet my expectations in multiple ways. The service technician arrived promptly, but spent an insignificant amount of time inspecting the heaters before leaving. He presented me with a bill for $80.

When I called to discuss the issue, the technician revealed that he would need to replace the pump if I wanted his services. However, when asked about the quality of the new pump, he seemed evasive and unwilling to provide any information. His response was vague and dismissive, implying that the price was not a concern but rather his service itself.

I was left feeling uncertain and uninformed about the product I would be receiving for an exorbitant amount of money ($1200). It's reasonable to expect clarity on what you're paying for, especially when it comes to expensive equipment. The technician's attitude suggested that he didn't value my business or my right to know what I was getting.

A second issue arose when the technician inspected the furnace and found that it was heating the house, but the temperatures were unstable. However, upon re-inspection at night, the heater failed to function, and the temperature dropped inside the house. Further investigation revealed that the shut-off valves had been left in the "off" position by someone.

It's unclear why these valves were closed, but it's clear that the technician didn't take responsibility for ensuring they were properly set during his initial inspection. I'm left wondering what other issues might have gone unnoticed due to a lack of attention to detail.

Fortunately, we've since discovered that regulating the thermostats correctly has resolved the issue, and the furnace is now working properly. However, I still stand by my decision not to use this company's services after their poor attitude and lack of transparency.

In retrospect, it's clear that as a customer, I have a right to know what product I'm receiving for my hard-earned money. It's unacceptable that the technician seemed unwilling to provide any information or reassurance about the quality of the new pump.

Great for DIY furnace repairs, good selection and fair pricing. Happy customer, thanks Rangel!

I've been handing out a lot of 5-star reviews lately, which is a welcome change. Recently, I went to Rangel to avoid an expensive service call and potentially costly furnace replacement. They delivered - got the right parts quickly and efficiently. The technician was polite and explained things clearly, making the experience painless. Thanks for being a reliable option.

I recently had my AC and furnace installed. The AC worked great all summer, but I experienced problems with the furnace within a month of using it. Thankfully, Fidel arrived promptly to resolve the issue on the same day. Their rapid response time is impressive, making me confident in their ability to handle any issues that come up.

Rangel Heating and Cooling exceeded my expectations in every way. They delivered exceptional reliability, professionalism, and customer service. I'm extremely grateful for the seamless experience. Thanks to the team, particularly an individual who showed remarkable expertise and courtesy - truly appreciated.

Mr. Rangel was very courteous and helpful in finding my replacement parts. He provided honest guidance on replacing the faulty components of my new furnace. His expertise and customer service were top-notch, making me feel confident in his recommendations. I'd highly recommend him and his business to others, and I wouldn't hesitate to return if needed for any future repairs or replacements.

Rangel's owner is genuinely kind and transparent. He does a thorough job, taking care to get it right on the first try. He clearly explains what's going on, making sure you understand the problem. Highly recommend for anyone in need of reliable service.

Great service provided with helpful assistance.

Fidel was fantastic - extremely helpful, efficient, and knowledgeable about AC repairs. His guidance on maintenance was spot on. If issues persist with your AC, I'd highly recommend Rangel without hesitation. Kudos to Fidel for an outstanding service experience.
