Reviews of local pros in Hillside, Illinois

I had a decent experience with this company, but there was an initial snag with the furnace installation. Fortunately, their management team took responsibility for it, which is more than most companies would do. They listened to my concerns and offered to send someone out on short notice, which I appreciated. What really stood out, though, was how they treated me as a client - professional courtesy all around. Given that things can go wrong, I wasn't upset, and I'm glad they got it right. Overall, the company's customer service impressed me, and I'm rooting for them as a family-owned business.

Excellent experience from start to finish. The AC/furnace installation was top-notch. They communicated clearly via email and phone, addressing all our concerns. Recommended by fellow residents, we'll definitely pass on their contact info to anyone considering a new system.

Raphael was top-notch, getting straight to the point with a clear diagnosis and solution. He didn't try to sell us anything; he just offered help and did it with a friendly, professional attitude. His demeanor put us at ease, so we're sticking with Chicago HVAC.

On Nov 24, 2025, Raphael returned to my church for the final fix. We weren't expecting any extra work, but they took care of everything on the spot without hesitation. What struck me was that this is a family-run business, and that personal touch really shone through – it felt like we were part of the team. That's genuine professionalism, and I'm impressed – great job!

Rafael responded to my emergency call on a Sunday, arriving promptly. He accurately identified the issue and worked methodically to resolve it, ensuring all was fixed correctly. The company maintains its reputation for integrity, fairness, and top-notch craftsmanship – consistently exceeding expectations.

We've relied on them for years, starting with a new HVAC installation when needed. When we encountered problems with our outdoor gas line this winter, they arrived quickly to assist with getting the furnace back online. Their service was friendly and professional, with prices that fit our budget. We appreciate their prompt attention and courteous demeanor.

I'm grateful for Chicago HVAC Repair Doctor after a string of poor experiences with other firms. The entire staff, from the initial call to the technicians, are courteous, competent, and dependable. I trust them completely and feel secure in their work – they truly deliver.

Outstanding Service!

Chicago HVAC Repair Doctors truly delivered an exceptional experience. From the initial call, they impressed with professionalism, punctuality, and warmth. Orlando took a genuine interest in my furnace's performance, taking the time to explain everything clearly and ensuring it ran smoothly before departing. It's clear that this company genuinely cares about its customers and takes pride in their work. My furnace is now operating better than ever, thanks to their excellent service – perfect timing for Chicago's chilly winter months. I wholeheartedly endorse them for honest, reliable HVAC solutions.

I'm extremely disappointed after being quoted an outrageous amount for a basic repair job. A reputable competitor offered the same service for significantly less, which only made me question this company's pricing structure. Despite having used them before for inspections and maintenance, they lost me as a customer with this extreme price hike. Their business practices seem questionable.

For clarity, I've looked into the cost of the OEM part needed - it can be purchased online at retail stores including taxes and shipping for $240. A licensed technician's labor rate is typically around $150 per hour. My competitor charged $800, which equates to a massive 133% markup that likely covers their overhead costs. I'm still unsure why this company would charge $1600. I hope others take the time to research and compare prices before making a decision.

Jesse M did a great job with my HVAC system maintenance, showing up thoroughly prepared and being polite throughout. He explained everything he was doing, provided photos, and broke down how the parts work, including potential points of failure that need to be replaced to extend furnace life. I appreciated Jesse taking the time to ensure I understood the mechanics involved.

They showed up right away for an additional estimate to replace our furnace in the condo. The quote was significantly cheaper than what another major supplier offered for similar gear. Installation happened within a day and everything's running smoothly now. I highly endorse their services.

We're extremely satisfied with Chicago HVAC's service. They replaced our old steam boiler and thermostat in our historic home without any issues. The technicians were efficient, knowledgeable, and courteous. They explained everything clearly, making us feel at ease. Special thanks to Joshua, Jesse, Rafael, Louis, and the entire administrative team for their professionalism, responsiveness, and helpfulness throughout the process. Their thoroughness and attention to detail are truly impressive.

Technician Orlando's visit was prompt and effective - he identified the source of the issue causing a popping sound when the furnace started up and made the necessary repairs without extra cost. He also tackled two other problems with our unit, demonstrating excellent customer service.

Excellent service from start to finish. The team kept me informed throughout, arrived on time, and showed a high level of professionalism and courtesy. Clear explanations and visuals helped with decision-making, including maintenance and repair options along with costs. I'll definitely be back for annual upkeep of my furnace and AC unit.

I've had an incredibly positive experience with Orlando from Chicago HVAC Repair Doctor. My radiator heating system just stopped working, and since I wasn't familiar with the issue, I was at a loss. What impressed me was that Orlando took his time to diagnose the problem, even though he didn't have much experience with my specific system.

He carefully identified the heat sensor as the culprit and went above and beyond by checking my furnace in the attic. He discovered a wiring error caused by a previous installer that had resulted in the interface burning out. He rectified the issue, explained everything clearly, and ensured both systems were running safely before leaving.

What's truly remarkable is Orlando's follow-through. When my system stopped working again, I called Chicago HVAC Repair Doctor and was promptly arranged for an evening visit. Just 15 minutes later, Orlando personally called me to let me know he'd be there in 30 minutes – a testament to his dedication. His level of care and responsibility is rare, and I'm grateful for the professionalism shown by this company.

I wholeheartedly recommend Chicago HVAC Repair Doctor; they truly stand out from other service providers.
