HVAC reviews in Chicago, Illinois

Marvin provided top-notch service, being extremely attentive to our needs and concerns. His expertise and knowledge were impressive, making our interactions enlightening. What stood out most was his genuine concern for our safety and well-being – it's clear he prioritizes customer care above all else.

My heating system went out on a freezing day and I needed urgent assistance. The repair team showed up promptly and fixed the problem without adding any extra charges beyond the standard service fee. One of the technicians, Zach, was particularly friendly and cooperative throughout the entire process.

Marvin provided top-notch service from start to finish. He quickly resolved my issue and took the time to explain the solution in detail. His professionalism and enthusiasm made for a pleasant experience. I'd highly recommend him for any HVAC needs - he truly delivered, leaving me feeling comfortable again.

All Temp did a great job. Their communication was top-notch, clearly explaining their costs upfront. They consistently responded promptly, which was reassuring when we had a sudden "no heat" emergency. I'm happy with their service, especially given the urgency of the situation.

Here is a rewritten version of the review:

The team at All Temp delivered excellent service. Maria was extremely customer-focused, friendly, and thorough in her work. Raul was prompt, courteous, and took the time to address my questions about the maintenance. Andrew went above and beyond by following up on the service, showing genuine interest in resolving any issues and ensuring I had a positive experience overall. Thanks for a job well done!

Prompt, reliable, and cost-effective. The technician was thorough in answering my queries. Excellent customer service. As a property manager and real estate broker, I can confidently endorse All Temp Heating and Air Conditioning's services.

All Temp Heating and Air Conditioning did a top-notch job installing two furnaces at my place for a fair price. The installation team showed up on time, worked quickly, and got everything just right. Nick was also super helpful during the inspection, helping me pick out the perfect furnaces. Overall, I'm extremely pleased with their work and would highly recommend them to anyone.

This business is solid overall. They consistently responded to my inquiries about the installation and service. Prices were reasonable too. The technician, Edwin, was very knowledgeable and displayed a high level of professionalism.

After 39 years in business, I've finally found a reliable partner. Their service is top-notch, with friendly and knowledgeable staff. As a new customer in need, they quickly alleviated a lot of stress. The technician who visited me took the time to thoroughly explain everything, easing my worries significantly. In an industry where trust can be hard to come by, this company has earned it - I've found someone I can genuinely rely on for my business needs.

We're extremely fortunate that All Temp stepped in when we needed them most - the morning the furnace stopped working on our first day of subzero temps in Chicago. They responded rapidly, sending a technician within hours. He replaced a critical component and we're now warm again. Our main concern was whether they'd be overwhelmed with emergency calls, but thankfully, they were able to assist us promptly. We're genuinely thankful for their timely help.

Had a great experience with Randy, who arrived right on schedule and got the job done quickly. He even took the time to teach me how to replace the humidifier filter and gave the boiler a quick glance without adding anything to the bill. They're one of my go-to companies for AC and heating, and I appreciate their transparent pricing - no surprises or extra fees! If you live in Lakeview, I'd definitely recommend them for reliable service.

AllTemp exceeded my expectations. My old AC needed repair, and after weighing options with Four Seasons, I picked AllTemp because of their reputation for quality work. The techs were top-notch - they listened to my concerns, explained everything clearly, and ensured the job was done right. Now my setup looks neater (photo 1) and I have a new ecobee (photo 2) that's more efficient. Their service truly surpassed expectations. If you're torn between AllTemp and Four Seasons, choose AllTemp - it's worth it!

My furnace was leaking water, so I reached out after 9PM. I got a quick response and an appointment set for the next morning. Technician Marvin arrived right on time, even before scheduled, and fixed the issue. He explained everything to me in a clear way. I'm very satisfied with the service and will definitely be calling them again this spring - specifically asking for Marvin.

We were once satisfied customers, but their recent service left us extremely dissatisfied with our heating system. They also fail to respond when we have complaints.

I want to make one thing clear: the situation was rectified when Mike apologized for the mistake made by the technician and provided a new air filter at no cost to me, along with installation. The technician who visited this time was pleasant and knowledgeable. Additionally, Mike offered free maintenance services for all our units for the next two years, which was a kind gesture that we appreciate greatly.

Despite these positive experiences, I've decided to cancel all services with them due to previous issues. It won't be until after 10 years that we'll consider switching to another company.

All Temp Heating and Air Conditioning exceeded our expectations. After reaching out for a boiler repair, the process was streamlined by Rick, who quickly scheduled an appointment. Jorge, the technician, turned up promptly and efficiently got my boiler up and running again - his professionalism and expertise were impressive. The entire experience was hassle-free thanks to their friendly service. I'm grateful for the top-notch work from start to finish.

Excellent service! The company responded promptly to my furnace issue, promising a technician within the same day before 5pm. Edwin arrived within two hours of my initial call. He efficiently diagnosed and fixed the problem, explaining each step of the process. A courteous and professional individual with excellent knowledge, making the experience even more positive.

All Temp's service was top-notch. They responded promptly after an early morning call, with a technician arriving later that afternoon. The tech walked me through what he was checking as he conducted the inspection. He efficiently resolved the issue by adjusting a sensor and left shortly thereafter, all within 30 minutes. Given the chilly weather lately, I'm impressed by their speedy response time.

I had a great experience with Jack, sales rep, Jose, and Jalin, installers - all very friendly, responsive, and knowledgeable. The professionalism was top-notch. I particularly appreciate the 10-year warranty on both parts and labor for my new AC unit from Bryant. Looking forward to minimal maintenance for years to come. Highly recommend All Temp for their excellent service and reliability.

I had a rescheduled appointment with AllTemp, but they almost blew it when they missed the new date. Luckily, Edwin showed up promptly after my call and I'm glad he did! He got to work quickly on my furnace and replaced the humidifier pad, which was a welcome fix. He also identified some damage in the heat exchanger that would've been costly to repair later. During his walk-through, he checked all the vents and used a camera to show me the damage. His explanation of what to expect in the future and maintenance tips for my system were incredibly helpful. I've learned so much about my HVAC in just 30 years of owning a home - it's amazing! AllTemp has earned a customer like me, and I'm looking forward to having Edwin back again this summer.

Jorge and Chris did an excellent job fixing our heating system issue. They identified the problem with moisture on the exterior unit causing it to shut off and replaced the faulty sensor along with other worn-out components. The team kept me informed throughout the process, explaining what would happen next before proceeding. After completing the work, they showed me the results and took the time to explain how the heater's humidity unit works better. Their professionalism and communication skills are truly appreciated.

We had a fantastic experience with Jorge and John from this company. I'm not exactly tech-savvy, but they explained everything in a way that made sense to me. They took the time to teach me about our boiler and even discussed potential upgrades for future air conditioning. What impressed me most was their honesty - they didn't try to push any extra services on us, but instead helped us make informed decisions about what would be best for our family's budget in the long run. We're now set with these guys as our go-to HVAC providers.
