HVAC reviews in Chicago, Illinois

The technician arrived promptly and explained the issues with my outdated setup. No hard sell, just helpful advice on upgrading. Options were presented and prices looked reasonable. A crew was dispatched the very next day for installation, which was impressive. Overall, I'm extremely satisfied with the service provided by Deljo.

Our technician, Gerardo, was top-notch. He fixed two parts and gave the furnace a thorough cleaning. When he last visited to inspect it, he explained what needed to be done and showed us images of the worn-out components and the faulty readings. Gerardo is an outstanding, intelligent, and enthusiastic technician. We've been consistently impressed with Deljo's services and their competent staff. They've delivered reliable work for years, and we're extremely satisfied with our experience.

I don't usually leave reviews, but my experience with Deljo was outstanding. My wife and I met with several companies about replacing our furnace and AC unit, and the consultant they sent over took the time to explain each option in a clear and non-pushy manner. He provided us with all the necessary information so we could make an informed decision. When we chose our units, he double-checked that each doorway and entry point would fit them properly. The installation crew was equally impressive - they were efficient, friendly, and left no mess behind. They worked in tight spaces without issue, which was a testament to their professionalism. Overall, I'm extremely satisfied with the service I received from Deljo and would highly recommend them.

Avoid this company's plumbing services at all costs. Our neighbors below us encountered a ceiling leak, and Deljo claimed to have initially checked our unit before discovering it wasn't there - conveniently not inspecting the bathroom where the real problem lay. The plumber boasted 30+ years of experience but couldn't pinpoint the issue until we paid him to fix the toilet. He reset it, despite being uncertain, as he was too confident in his own abilities. However, further investigation revealed that the leak originated from a shower on the opposite side of our unit, beneath another bathroom entirely - an area Deljo didn't even bother to examine. This debacle cost us a lot of time and money, ultimately leaving us with a costly mistake.

This company is reliable, punctual, and courteous. The technician was thorough in assessing the entire system during the maintenance visit and provided a clear outline for future work. We're extremely satisfied with the service received.

Gerardo set up and assessed our heating system quickly and efficiently. He was professional, friendly, and explained everything clearly so we could understand how to fix the issue. He's knowledgeable about the entire system and walked us through options for both their services and DIY solutions. The price was reasonable. I'd definitely recommend him to others.

Sam was excellent - very knowledgeable and a great communicator. He thoroughly assessed the issue, offered solutions and even enhancements beyond initial suggestions. Never pushy, Sam explained everything clearly, helping me grasp the condition of my furnace and available options.

Our same-day appointment was hassle-free, thanks to easy online booking. The technician showed up right on time. Sam was incredibly friendly and explained the boiler issue and possible fixes without sugarcoating. His professionalism and honesty won us over. We'll call Deijo again for any future needs and would highly recommend them, especially in emergency situations.

We've had Donny Gjoni come out twice now, and both times have been incredibly smooth. He's a top-notch technician who knows his stuff. Friendly, efficient, and professional, he breaks down complex problems into manageable steps. His expertise shines through, and the work is done quickly and well. We're very satisfied with his services, and we wouldn't hesitate to recommend him to anyone.

Donny Gjoni exceeded expectations, displaying exceptional patience and helpfulness during his multiple visits to assist me. His thorough evaluation, including a water test, impressed me greatly. While the initial quote was steep, my only criticism, I found the overall service to be excellent value for the price. Donny's professionalism earned him top marks.

We bought a new condo and needed repairs to our HVAC system, which Deljo's team handled promptly and efficiently. Izzy, in particular, was top-notch - extremely professional, helpful, and courteous throughout the entire process. I highly recommend Deljo for any heating and cooling needs; Izzy's service was outstanding.

Gregory provided top-notch assistance, demonstrating a thorough understanding of the problem. Unlike other companies who gave our furnace a clean bill of health, Gregory dug deeper and identified the root issue. He effectively communicated his findings and proposed solutions, ensuring we felt informed and confident in the repair process. His professionalism and politeness were impressive, making for an exceptional customer experience.

I'm extremely satisfied with the work done on my home. The installation team, led by Luis and Anthony, did an excellent job on my furnace, while John provided a thorough estimate beforehand. Drew also handled a maintenance call efficiently. Although I've lost the name of the initial point-of-contact, they were equally impressive. Due to issues with my 28-year-old furnace within two weeks, I received an estimate for a new unit and had it installed promptly when it stopped working on one of the coldest days of the year.

The scheduling process was seamless, thanks to small time windows that were consistently hit. I'm also grateful for your flexibility in accommodating my needs. Unfortunately, this experience has led me to switch plumbing services elsewhere, as I won't be requiring additional work from you. Still, if future issues arise, I trust that they will be handled well.

I've had my fair share of dealing with pesky plumbing and heating issues, especially if I don't know what I'm doing myself. That's why I was relieved when I hired Deljo for both their HVAC and plumbing services - they really delivered.

Firstly, it impressed me how thorough the HVAC tech was during the inspection. Instead of just telling me that my furnace needed replacing, he used a camera to show me exactly what was wrong with the heat exchanger. That kind of transparency is rare in this industry, so kudos to Deljo for being upfront and honest.

What really sealed the deal for me was their ability to send out a salesperson to help select a new, efficient system that could replace my old 20-year-old furnace. And to make matters even better, they were able to get an installation crew out on the same day as we were experiencing frigid temperatures in Chicago - it was a lifesaver.

Of course, nothing is perfect, and we did encounter some issues with the new system shortly after installation. However, Deljo sprang into action quickly and sent one of their own installers to fix the problem within hours. I was impressed by their speed and dedication to getting things right.

For my plumbing work, Deljo offered a comprehensive home report that gave me a clear understanding of what needed fixing. They also provided individual quotes for each job, making it easy for me to prioritize which issues were most pressing. The plumbers themselves were friendly, knowledgeable, and took the time to explain everything they were doing.

One particularly nice touch was when they moved the condensate drainage plumbing from my old furnace over to my new sump pump at no extra charge - it had been a mess before. Their customer-first approach put me at ease, and I appreciate that their prices are competitive with other local HVAC and plumbing companies.

All in all, my experience with Deljo was top-notch, and I'm already looking forward to using them again in the future when something inevitably goes wrong (and it will!).

Deljo exceeded my expectations from start to finish. I booked an appointment for a full HVAC system replacement and was kept informed every step of the way about their progress and any changes to the schedule. What sealed the deal for me was the superior service provided by Deljo compared to another company that offered similar pricing. My technician, Matthew, took the time to explain what mattered most to me in a new system, how it would function, and kept me updated on his progress. The installation team arrived efficiently, communicated clearly, and demonstrated professionalism throughout the process. I have no hesitation recommending Deljo and plan to continue using them for future maintenance needs.

Prompt, reliable, considerate with budget, respectful, fast response!

Great job, very friendly, definitely recommended.
