HVAC reviews in Chicago, Illinois

I'll be back for more work with Larry and can't wait to refer him to others.

Larry did an excellent job - very professional, reliable, and trustworthy.

We had a busted AC in the morning, so we contacted another company - what a pain, waiting forever for a callback. We quickly switched to Zep's and they sent someone over ASAP. No fuss, no muss, and surprisingly affordable. Extremely satisfied with our experience; these guys really delivered on their promises.

Larry was top-notch - super professional and got the job done fantastically. Highly recommend them for any HVAC needs.

We've had a consistently great experience with Zepsa and their team. For three years, they've handled all our HVAC needs in Chicago, delivering top-notch service every time.

The service team answered calls clearly and thoroughly. The technician's performance was excellent and punctual, leaving all ductwork neat and well-organized. The turnaround time was spot on.

Larry's team did a great job fixing my furnace issues. They communicated clearly, kept schedules on track, and delivered reliable work.

Had a top-notch experience with this service provider after my air con stopped working during a scorching heatwave. They arrived quickly, got the job done swiftly, and delivered excellent work at a fair price - highly recommended!

This company truly exceeded expectations with its lightning-fast response and impeccable professionalism. Unlike the average repair service, they delivered a top-notch job without any surprises. Their commitment to excellent customer service is unparalleled - it's clear they're dedicated to getting it right from day one. I've never had such a seamless experience, and I have no doubt they'll deliver again in the future.

If you need reliable service with pleasant staff, look no further than Zepsa. I recently booked a service through their website and had a tune-up and heater inspection done. The experience was positive, which is why I'm planning to return to them for future heating needs.

The technician was transparent about what to expect beforehand, arrived on schedule, and completed the replacement of both furnaces and AC units within two days. The job was done efficiently with no additional cost for the extra work done. Pricing was fair considering the value received.

Larry is top-notch when it comes to HVAC work in Chicago. He did a great job installing my A/C and also handles yearly tune-ups. He's always reliable, polite, and does the right thing.

This company's team of technicians delivers top-notch service. As a seasoned writer of service reviews, it's clear these guys are straightforward from the start. After multiple visits addressing everything from minor issues to full replacements, their professionalism shines through. Urgent jobs were tackled promptly, while others received creative solutions that balanced quality and cost. I appreciate being kept informed throughout each visit, and the work is consistently done correctly. Transparency in pricing is also commendable. Their integrity has earned my trust, ensuring I'll return for any future needs.

I'd give this company more than 5 stars if I could. They responded quickly, sending a technician named Julio within 2 hours to diagnose the issue with my furnace. It's their third faulty motor in three years - a recurring problem that they've now addressed by re-piping the exhaust system to a larger diameter. Their customer service is exceptional and they clearly prioritize property owners' needs. I'm extremely satisfied with their work and would highly recommend them as the best HVAC company for my properties.

Excellent experience with this home services company. After a call on Monday about my 20-year-old AC unit failing, someone arrived within an hour to diagnose the issue. They explained that it was faulty and offered a replacement schedule for Thursday morning. Due to anticipated extreme heat, they actually completed the service on Wednesday evening. The staff were professional, courteous, and delivered outstanding workmanship throughout.

They did a great job with nice guys who got the work done right. Quick assessment and they showed up when promised. The quote was spot on. We asked for a new furnace since ours is old and they gave us a fair price to replace it too - could do it the next day if we wanted. They did excellent quality work, no complaints at all. If you need someone to fix stuff or install new, these guys are worth considering.

This company really delivers. Larry arrived on time, accurately identified the problem with my furnace and resolved it efficiently. The price was reasonable considering the service received.

I recently had Zepsa Mechanical install a humidifier and thermostat, and the experience was top-notch from start to finish. They got back to me quickly, asking for all necessary info and photos upfront to avoid any surprises or unnecessary costs. Their estimate was accurate and fair, and they stuck to it.

They're also super flexible - I could schedule an early morning appointment that fit my schedule. The work itself was done efficiently and correctly, with no issues.

What really impressed me was when I pointed out a slight temperature reading discrepancy on my thermostat after the installation. They looked into it, figured out the problem, and responded a couple days later with a simple solution that worked. It turned out to be a draft in the wall, which they fixed by plugging up the hole for the thermostat wires.

What struck me was their willingness to put in extra effort to resolve the issue - it could have been a defect in the thermostat itself, but they didn't need to follow up like that once the job was done. It shows they genuinely care about doing things right by customers. I'd highly recommend Zepsa Mechanical for any HVAC needs.

Great service from this HVAC company. They got a new furnace and water heater installed quickly and efficiently. The work was done well and they're very responsive - even with follow-up questions I had after the job. Would definitely recommend them to others.

The team from Zepsa is top-notch. They show up on schedule, explain the issues they identify, and provide transparent quotes for their services. No gimmicks or exaggerations. If you want reliable work done without pretenses, look no further than Zepsa. Their recent installations of smart thermostats, a zone damper, and humidifier were spot-on - everything is working flawlessly, and the job was completed on time and within budget. They'll be back in April to inspect the AC, and I'd highly advise taking advantage of their expertise.
