HVAC reviews in Chicago, Illinois

We hired them for the furnace and AC installation, which started the next day and wrapped up on schedule. The job was done to high standards, right from the initial survey through completion. No surprises or added fees - a straightforward deal at a fair price.

I had a great experience with PhD Heating & Cooling. They recently installed my new furnace and did it efficiently and affordably. The whole process was hassle-free and the result is exactly what I wanted - highly recommended.

Exceptional customer service and work quality from an outstanding owner who consistently delivers with great responsiveness and dedication.

I had a gas furnace that wouldn't start, so I sent out a request on Yelp for help. Dmytro responded promptly, even late at night, and we scheduled an appointment for the next morning at 8 am. He arrived within three hours to diagnose the issue and found it right away - a broken gas valve.

He broke down his costs for the call, parts, and labor, and asked if I wanted him to do the repair on the spot or pick up the part and return later. He also offered annual maintenance for a small fee, explaining what he'd do, but never pressured me into it.

When he returned that evening, he installed a brand-new gas valve. Before doing so, he checked if it was still under warranty to see if it would reduce the cost of the call. After installation, he ensured everything worked correctly and cleaned up. He left me with a receipt of the work done, some referral cards, and extra services provided by the company - all without pushing me into getting anything extra.

Overall, Dmytro was a nice guy who got straight to business. His professionalism and efficiency made the experience pleasant, and I'll definitely call him back for future heating and cooling issues.

PHD Heating and Cooling got everything done in one day - new AC unit condenser, furnace, and humidifier - after just 3 days of contacting them. This was during a ridiculously hot week of summer, but they made it happen urgently. Dmytro was super responsive, professional, and knew his stuff; top-notch work.

Excellent service! Dmytro replaced my gas furnace, hot water heater, and humidifier in a single day. He was courteous, efficient, and provided valuable guidance on appliance selection. His attention to detail and tidiness were impressive. The quality of the work is top-notch, making him highly recommended for similar tasks.

This business does everything right from start to finish - easy, transparent, and quick. Dmytro went above and beyond, finding a hard-to-get replacement part just in time for the holidays. His expertise is exceptional and I highly recommend him to anyone seeking top-notch quality work at a fair price. The whole experience was seamless, with minimal hassle or wait.

I've encountered some exceptional service from this HVAC company. When my furnace gave out during a particularly harsh cold snap, they responded promptly - even on a Saturday. Dmytro was the technician who got it up and running again, but it soon became clear that replacement was the way forward. Within two days, he installed a new unit. What impressed me most was his willingness to explain options and provide expert advice, demonstrating a deep understanding of the latest technology.

The installation itself was surprisingly quick - done in one day - with impressive workmanship and attention to detail. The team left the workspace cleaner than they found it and disposed of the old equipment properly. Overall, this company has set a high standard for HVAC repair and installation.

I hired PhD Heating after reading numerous 5-star reviews. My experience lived up to the hype. From the initial call, I waited about 90 minutes for the work to start and finish. The process was surprisingly swift and hassle-free, and they handled everything with a high level of professionalism. I'll definitely be using them again and can confidently endorse their services.

I was pleased with my experience working with this company. They sent someone who thoroughly examined my old furnace and AC units, which were over 20 years old, and presented a few replacement options. While they weren't the cheapest choice, they provided clear explanations. The installation process took two days - one for delivery due to the AC being on top of a four-story building that required crane lifting - and everything went smoothly. I've had both heating and cooling issues since the new system was installed and am very satisfied with the result.

We're extremely satisfied with the service we received from Dmytro. He performed maintenance on both our furnace and A/C units, which are about 30 years old. We were able to schedule replacements within a short time frame after the initial visit, and he completed both jobs in one day. His team worked quickly and efficiently, and they were always responsive and professional. What impressed us most was that Dmytro noticed an issue with our thermostat and took care of it before working on the A/C unit replacement, which is situated on top of a four-story building.

I referred my colleague to Dymetrov after they had a good impression. He arrived promptly, evaluated our issue, and provided multiple quote options by morning. We secured a furnace replacement for the following day. I was impressed with his professionalism - he's tidy, organized, and explains things clearly. His work was thorough and accurate. I'll definitely be recommending Dymetrov to others and using their services again.

Dmytro does a fantastic job - he fixed my AC unit in October 2024 with expertise and professionalism. Always punctual, friendly, and thorough, I highly recommend him for any service needs.

I contacted this company about my old boiler and they got back to me right away to schedule an appointment. Dmytro showed up and had a deep understanding of hot water heating systems, which was a huge relief since it's not easy to find someone who knows their stuff. He walked me through the issues with my system and proposed a repair plan. What struck me was how he identified all the places where previous work had been sloppy or misunderstood - essentially, he found all the shortcuts that had led to problems. He explained everything clearly so I knew what was going on. We agreed on the scope of work and they did it quickly and with high-quality results. I'd definitely use them again for any future heating needs.

My air conditioning gave out in the middle of the night, so I needed help ASAP. I chose PhD Heating and Cooling because they had great reviews for being affordable and providing top-notch service. I reached out at 8 PM and a technician was there by 10 AM the next day - impressive speed. The tech showed up on time, identified the issue, explained what was wrong in detail, and fixed it spot-on. Compared to other big companies, PhD had the best price for the job. What impressed me most was how they got it all right: price, quality, and getting it done quickly - a rare combination that exceeded my expectations hands down.

The technician failed to provide upfront costs, simply stating that my system needed freon without disclosing the expense. When I agreed to the addition, he presented me with a bill totaling $500, including 2.5lbs of freon and his service fee - a charge that seemed excessive at the time. If only I had known the cost beforehand, I wouldn't have agreed.

Furthermore, it appears the technician skipped a crucial step: checking for leaks in the system to determine why the freon was low. He claimed he didn't perform this test because it would incur additional costs via a pressure test. This lack of transparency and attention to detail is unacceptable.

To make matters worse, the technician was over 30 minutes late for our scheduled appointment, despite my clear communication about an early work commitment. The overall experience has left me extremely dissatisfied, and I will not hesitate to discourage others from using this company's services.

We've been dealing with persistent AC problems for over a month before PhD Heating & Cooling stepped in. Their service was top-notch, from initial assessment to a swift and thorough installation of the new unit. Excellent communication skills, they kept us informed every step of the way. We appreciated their straightforward approach, never trying to upsell or complicate things. The job was done professionally and efficiently. A very good value too. I've already spread the word about this reliable company - what a refreshing change from usual experiences!

This HVAC company is top-notch in Chicago - I wouldn't recommend anyone else. As a real estate agent, I've sent all my clients their way because they're responsive, honest, and won't try to push unnecessary work. When I asked about my furnace's condition, the technician told me it was just poorly installed, not defective - that kind of transparency is refreshing. The owner, Dymetrov, is fair and knowledgeable, and his team did a great job cleaning my vents. They even came back on short notice to finish a repair when my furnace went out in freezing temps while I was away. Their level of service and attention to detail is impressive. Save yourself the hassle and don't bother with other companies - you'll only waste your time and money.

I recently had the chance to work with PhD H&C for my heating and cooling needs, and I'm thoroughly impressed with the service they offered. From start to finish, the process was smooth and well-managed.

They showed up on time and were extremely knowledgeable about their craft. They took the time to inspect my system thoroughly and walked me through all the options available. The technician not only had the skills but also a friendly demeanor, making sure everything got done efficiently with minimal disruption to my daily routine.

The repair was done to a high standard, and I noticed an immediate improvement in the comfort of my home. They went above and beyond by providing helpful maintenance tips and answering all my questions.

What stood out most was their attention to detail and commitment to customer satisfaction. They cleaned up after the job and followed up to ensure everything worked perfectly.

I'd highly recommend PhD H&C to anyone needing heating and cooling services. Their expertise, professionalism, and excellent customer service make them a top pick.

We were desperate for a solution to our years-long boiler and zoning nightmare. Multiple companies had come and gone, trying various fixes without ever getting to the root of the issue. It was a frustrating and exhausting cycle.

PhD Heating & Cooling took a different approach. They didn't rush in and pretend to fix things right away. Instead, they came back multiple times, thoroughly testing the system each time, and stuck with it even when new problems arose. The job took about four days of their time to get everything sorted out correctly. We did have to pay more as the scope of the work became clear, but what really impressed us was that they actually saw it through.

For someone dealing with a complex boiler or zoning problem like ours, PhD Heating & Cooling is the only company we'd trust. They delivered on their promises and finally fixed the issues that had been plaguing us for years.

My experience with PhD Heating & Cooling was top-notch. The heat exchanger in our furnace failed, so we needed a replacement. They offered me a great deal and had it installed the same day. The technicians were professional, honest, and thorough. Not only did they fix the initial issue, but they also uncovered another problem. I highly recommend this business.
