HVAC reviews in Chicago, Illinois

Harvey and Zamuel did an outstanding job installing my new furnace, even going above and beyond by coming out on a Sunday after my old system failed on the previous weekend. They're now top priority for me as a loyal Oasis customer.

This guy was ridiculous, claiming our unit was working fine despite it being woefully inadequate - he even stood there holding the vent to prove it wasn't blowing hot air, just lukewarm at best. What a waste of money. He reckoned we needed a whole new furnace instead of just replacing worn-out parts. The solution's obvious: short cycling, not a faulty appliance. His recommendation was laughable - $6000 is outrageous. I wouldn't trust Oasis with my business if you paid me.

Oasis has provided reliable maintenance for my heating system over the past two years, resulting in a consistently positive experience. Scheduling is hassle-free, with prompt responses and actual personnel involved throughout the process. In contrast to my recent issues with Xfinity, Oasis's technicians arrived on time both visits, were courteous, and executed their work well. The absence of unnecessary sales pitches fosters trust. I'm confident in their expertise and will continue to rely on them for any future heating-related needs.

Called in a pinch and got same-day service no problem. Fernando, the technician, turned out great - fixed my furnace super fast considering the situation. He was professional, knowledgeable, and explained everything clearly. No surprises there. If I ever need HVAC work done again, they're my go-to choice.

Joseph from Oasis Heating did a fantastic job servicing my furnace for winter. He was incredibly thorough and explained everything clearly so I understood what was happening. He replaced both filters, double-checked everything before leaving, and left it working perfectly. Professional, friendly, and knowledgeable - I'm sticking with Oasis Heating and requesting Joseph next time.

I've had great experiences with all technicians who've visited my home. Damir was the first to assess my issue and pinpoint carbon monoxide leaks from my furnace. He explained everything clearly and got a replacement installed within days. Vaha, Anel, and their team arrived on schedule, worked professionally, and completed both an AC installation and new furnace in under 4 hours. Their service has been top-notch and I'm highly recommending Oasis plumbing, heating and cooling to anyone in need of reliable home services.

I hired this company to diagnose my furnace issue. A technician named Fernando arrived promptly, inspected the unit, and had it operational within a very short time frame - impressive efficiency. He was trustworthy and transparent in his work. I'm pleased with the service and plan to refer them to others. Thanks to Fernando for his professionalism.

Oasis Plumbing, Heating & Cooling really blew it out of the water! Michael was a lifesaver, providing top-notch service with impeccable integrity. He took the time to break down every step in detail and patiently answered all my queries. The quality of work was exceptional, and I was thoroughly impressed by his commitment to doing things right.

The technicians were courteous, informed, and prompt. The company is accessible and price-wise. A heater malfunctioned on December 30th, but a visit arrived the following day, Christmas Eve, to diagnose the issue. Their work is reliable; we'd definitely suggest them for routine maintenance and repairs.

Their technicians are seasoned pros who know their stuff when it comes to heating and cooling problems. They're always prompt, explain what they're doing, and don't try to upsell you on anything that's not necessary. Whether it's a new setup, routine maintenance, or an emergency fix, they deliver top-notch service with no hassle. The team is transparent about pricing and never pressure-sells.

What really makes Oasis stand out is their commitment to customer happiness and long-term reliability. The staff are friendly, straightforward, and genuinely care about getting the job right for each home or business. You can tell they value building relationships over just making a sale – every project becomes an opportunity to earn trust. Their work speaks for itself: consistent comfort and energy efficiency that's hard to beat.

Oasis is a company you can rely on for dependable service, expert craftsmanship, and peace of mind from one season to the next. They're not perfect, but they always try their best and follow through on what they promise.

I had a great experience with Oasis. My Navien tankless water heater stopped working and Chris was able to fix it without replacing the whole unit like other companies suggested. He was professional, friendly, and did an excellent job. I've also used Oasis for my HVAC system maintenance over the years and their employees are always honest, genuine, and seem to genuinely care about their customers.

I rely on Oasis whenever I've an issue - they deliver consistently. Their technician, Joseph, showed up promptly and efficiently fixed our heating system during the coldest winter days. He even tackled a stubborn closet door that keeps dust from reaching the furnace, protecting my kids from potential harm. Thanks to Joseph and the entire team for another successful visit; I'm grateful for their expertise and reliability.

I had a fantastic experience with this plumbing service from start to finish. From the moment I called, the person who answered was warm, helpful, and got me scheduled right away. The technician showed up on time, explained everything clearly, and did an outstanding job. I'm thoroughly impressed with their reliability and speed - they truly exceeded my expectations and I'd definitely use them again in the future.

We can't say enough about the exceptional service our family received from Oasis Heating and Cooling. With multiple allergies running rampant in our household, we decided to take action and have them clean our air vents. Given the scope of the job - a 6 bedroom, 5 bathroom home - it was clear that this wouldn't be a quick or cheap fix.

The team arrived at 7 am sharp, which was impressive given our household's unique requirements (we don't wear shoes). They came prepared with shoe covers, a thoughtful touch that put me at ease. The technicians were consummate professionals who remained patient and kind with our kids, who had a plethora of questions for them. In fact, they even engaged in a game of "squat challenges" and pushups, which was a heartwarming display of their down-to-earth nature.

Throughout the day, the team worked diligently from room to room, leaving a spotless trail behind them. They took a break for lunch before returning to finish the job, demonstrating a clear commitment to quality workmanship. What struck me most was the way they handled their equipment, making sure it was properly maintained while also respecting our home's space.

Two years ago, we faced an unexpected crisis when a severe snowstorm on Christmas Eve caused our attic furnace to shut down due to frozen condensation in the vent exhaust pipe. With two young children at home, including one who was just a baby, we were genuinely worried about their safety. Oasis Heating and Cooling sprang into action, dispatching a team to our doorstep the very next morning at 6 am. Despite being slammed with calls that day, they prioritized our situation, demonstrating a level of commitment to service that's hard to find in today's world.

We're still reeling from the exceptional care we received from Oasis Heating and Cooling. Their professionalism, kindness, and dedication to their craft are truly commendable. We feel grateful for companies like them, who put people above profits. Thank you for all your hard work!

I've had a fantastic experience with Oasis Plumbing, Heating & Cooling from start to finish. In a perfect storm of bad weather and weekend bookings, they still managed to show up on time and tackle my Nest thermostat wiring and furnace setup.

The technician, Naem, was spot on – punctual, knowledgeable, and incredibly courteous throughout the entire visit. He took the time to explain everything clearly and ensured the system was functioning flawlessly before leaving. The phone representative was equally impressive, offering respectful, accommodating, and genuinely helpful support when I called in a bind.

I'm truly grateful for their timely intervention and professionalism.

Our heat stopped working in the middle of winter. Oasis arrived promptly to diagnose the issue and replaced the furnace within a day. The team's customer service was top-notch, with friendly and helpful staff throughout. Fernando and Joseph handled the installation efficiently, explaining their work to ensure I understood what was happening.

Damir, Mark, Joseph, Vaha & Anel did an excellent job installing our new HVAC system. The installers were extremely professional and courteous, making a big job feel remarkably efficient.

Overall, the company exceeded expectations in every aspect, including prompt service. We're highly satisfied and plan to rely on them for all our future HVAC needs.

Joseph was excellent. Straightforward and knowledgeable, he diagnosed and resolved my heating issue quickly. He provided clear explanations without any pushy sales pitches. His professionalism impressed me, especially given his expertise. When it's time to replace the unit, I'll definitely choose Oasis - their service has earned my trust.

Oasis has been our top choice for home services for eight years due to their strong reputation for trustworthiness and reliability. Recently, we had an annual furnace checkup performed by Joseph, who demonstrated expertise, speed, and thoroughness. He also provided valuable insights into a potential water heater replacement, making us feel informed and supported throughout the process.

We've been relying on Oasis for over a decade, with their help replacing both our furnace and AC unit during this period. We've never had any issues with heating or cooling since then. The technicians and managers are consistently courteous and knowledgeable. Like Joseph today, who took the time to explain how our furnace works and its internal safety features - this attention to detail is greatly appreciated.

This company is straightforward and delivers top-notch service. They arrived promptly within two hours of my initial call. Technician Damir was exceptional - he identified the problem with my furnace swiftly and demonstrated expertise. He's also extremely courteous and professional, making a great impression.
