Customer Reviews

Oasis is great! My furnace is almost 30 years old and for a reasonable price they were able to do the repairs. First Danny came to evaluate. He showed me what was wrong. They had to order the necessary parts to fix it. Today Hani and Fernando came to do the repair. They were efficient and courteous. I will definitely use Oasis in the future.

Emily H.

I called Oasis this morning because my furnace was not working. Within 20 minutes their technician, Danny, arrived. Danny was able to assess the situation, provide an immediate fix, and even commit to returning Monday morning to provide additional services needed. Danny was friendly, informative, professional and FAST! I am thankful I called Oasis for my immediate heating needs and that Danny was the technician who arrived. Top notch service! Highly recommend.

Megan R.

I have been using Oasis since 2019. They are reliable, efficient, and their prices are reasonable. The customer service is amazing. Every tech I’ve had come out is knowledgeable, friendly, and professional. The owner, Mike, is hands on and works with you every step of the way. Highly recommend Oasis.
Services include: furnace and AC replacement; annual maintenance.

Nicole U.

The folks with Oasis showed up right on time and replaced my entire furnace and condenser in about 4.5 hours. I had just redone my laundry room where the furnace is and they took great care not to damage anything. Overall very happy with the service and very happy with how respectful the installers were.

Josh D.

Danny and the folks at Oasis got us a great deal on a new furnace and AC. The install took about 4 hours, and they were also super responsive throughout the process. It was about as good of an experience I’ve had with an HVAC company. I’d highly recommend!

Brian C.

Oasis was incredibly responsive and efficient! My call to them on a Friday night during a cold spell was returned within 10 minutes and he scheduled a tech to come to my home at 7 the following morning. At 7 the tech was there, examined my furnace confirming that a new motor was necessary. He searched for the part, sent a quote and returned with the motor by noon the same day to install it. You can’t beat that!!! I will be using Oasis for all my future furnace and A/C needs.

Gayle V.

Oasis has always been great to work with and their staff are quick and efficient if issues arise. When our air conditioning broke down during the heat of the summer, they provided a quick replacement at a competitive price. Their staff are always extremely kind, respectful, and knowledgeable.

Sam C.

I had a great experience with Oasis. Our furnace had issues on Thursday night and Oasis came at 7am the next morning, and we found out we needed a new one. They provided all the necessary information to our condo building so we could get an emergency replacement on Saturday morning. Within 36 hours we had a brand new furnace and the installation team did a great job communicating on their work and how to use the furnace. The owner, Mike, and his team are great and I really appreciated the attention they gave to this matter. I would highly recommend and will only go to them in the future.

THE BEST EXPERIENCE in my 68 years with a home repair. Replaced my central AC. I had worked with Oasis 6 yrs ago small project and was impressed so when this major repair came up I got a couple quotes and I cannot BE HAPPIER WITH MY DECISION to hire OASIS. GOOD HONEST PEOPLE. On time, polite, always informed, left my home better than they found it and an extremely reasonable price. THANK YOU to DAMIR, AMIR, AMAR and JASON and the owner MIKE and NATALIA.

Response from the owner:Thank you, Mary, for your wonderful review and for trusting Oasis again, this time with a bigger project! We’re glad to hear that our team provided you with such a positive experience. We appreciate your kind words and support!

I have worked with Oasis twice before and both times they have been PHENOMENAL. They're quick, helpful, and actually care about what's best for you, not just what makes them the most money.

The first time, my AC went out last summer right before this big heat wave. Every other tech I had out told me I would have to replace the whole thing, and they couldn't do anything for me until after the slate of 95+ degree days we had coming up. Some told me that it would cost thousands to fix my current problem. Oasis came out and 10 minutes later, my tech Damir tells me he's fixed my AC by replacing a part -- he carries a spare in his bag. So he's patched it for the summer -- a $300 solution when I was prepared to spend $8,000+. He also walked me through what was wrong with the system, what would need to be replaced eventually, and how to keep the AC going through the rest of the summer. I felt his price was very reasonable (he even took a little bit off because he misspoke when he told me the original price) and he was able to truly help me, not try to get more money out of me.

So this spring, I called them to finally get the AC replaced. First, they came out to do the estimate and explained all the options to getting the AC up the 5th floor. They are very focused on making sure you have a good experience (when I suggested not craning it up all the way, they responded basically "no, that's silly, that would just cost you more money than you need to spend. We're not doing that").

They came out today and in the course of doing the work, found a previously undiscovered leak in the HVAC closet. They immediately called their plumbing team (Amer and Steve) who cancelled other calls to come and help. Amer and Steve thoroughly diagnosed the leak and fixed it fast. They spent almost an hour talking me through the issue and different next steps to get the mold dealt with. The AC work has been great so far -- the team had to move my appointment to Saturday to save me about $9,000 in fees to the city and have been very communicative about the change.

TL;DR: If you need a plumbing and heating company, Oasis should be your first call.

Response from the owner:Thank you, Layne, for sharing your excellent experience with us! We're glad Damir could provide a quick and affordable solution for your AC, and we appreciate your kind words about our team's efforts to accommodate you on short notice. Your satisfaction is our priority! We are here for all of your HVAC and Plumbing Needs!

We hit furnace trouble on one of the coldest days of the year, and Oasis still got us in the same day—on-site within two hours of my call. Naem was our technician and was fantastic: kind, quick to diagnose, and had the heat running again in under 30 minutes. They also installed our rooftop A/C and did an excellent job. We’re really grateful for the whole Oasis team and their great service. Highly recommend them to anyone in Chicagoland.

Update 4/23/26: our furnace worked great the rest of the season! Also wanted to add we just had our AC serviced today by Joseph at Oasis and he was excellent. Timely, helpful, and laid out repairs that would likely be necessary in the next couple of years. Great service and we’re thankful for making us aware of what to plan for in the future!

Response from the owner:Thank you, Matthewjn, for your wonderful review! We're so glad to hear that Naem provided fantastic service and got your heat running quickly. Your recommendation means a lot to us, and we appreciate your support for the entire Oasis team!

Hayley Gebhardt

Great experience with Osais! very professional and helped me understand the problem. they fixed everything perfectly. I will be calling them again!

Susan Pachera

AC service: Joseph was very friendly and efficient. He kept me updated on the work he was doing. I’ve used Oasis for years and am always impressed with their professionalism. Very reasonable prices on the HVAC services.

Prior review:The work was done quickly and plumber was nice but quite expensive for a short job so I’ll go back to my previous plumber

Response from the owner:Thank you, Susan, for your feedback! We're glad to hear the work was done quickly and that you found the plumber nice, and we appreciate your honesty about the cost. We hope to still work with you for all your HVAC needs!

Special recognition goes to Hani, and the technicians Damir, Amir, and Vaha. Incredibly efficient at the task, for the thorny HVAC installation. Amir assured me the most capable crane guy is coming to lift the AC to the rooftop through the trees. What was scheduled to be a full day project finished before noon after all testing. Especially Hani was different from our first meeting - he explained all the components clearly in a way that a layman can understand and I appreciated taking his time to walk me through his thought process and how he arrived at his proposal. It takes thorough experience on the actual job as a technician and leveraging that to face clients. Friendly guy and easy to talk to. After the task was done, his follow up service was top notch. This review can only do so much to help them. I’m glad to be part of the effort supporting their business.

Michael Litchfield

Oasis is always on time and courteous. Will hire again!

Patrick Huurman

Scheduling was great, but the service itself was lacking: technicians did not complete the task before leaving, instead offering a confusing explanation that was not true upon further research. They left my house for ~30 minutes to get equipment and let themselves back in - no knocking or courtesy text. Upon trying to have my task completed, I’ve been met with near radio silence. I had such high hopes based on the service prior to my actual appointment.

Joseph was fabulous. On time, thorough, and very informative. Since we just moved in, he was especially careful to make sure we understood how this particular system worked, the required maintenance for it, and potential upgrades or repairs down the road. Best HVAC technician we’ve ever had.

Hollina U

I had worked with Chris and the team a few months ago when my furnace stopped working and had a positive experience, so I reached out to them for what I thought was proactive maintenance on my AC. Turns out the whole thing had to be replaced (makes sense, it was very old). Naim(?) was super patient and kind with me as I asked a ton of questions to understand the situation - he had the same amount of patience when he came out to assess my broken furnace too!

Damir and team who came out to replace my AC were super kind as well, doing the job efficiently and even offered to help move my stuff back into the hallway after they were done.

Something that stood out to me about this process was the customer service - throughout the process, Mike kept me updated on scheduling, and the whole team overall were great to work with. I'm glad I found a reliable team for my HVAC needs moving forward!

Response from the owner:Thank you, Hollina! We're so glad to hear you had a positive experience with Chris, Naim, Damir, and the entire team. Your appreciation for our customer service means a lot to us, and we're here for all your HVAC needs in the future!

Luke Kinney

Oasis is a great company with great staff. They are American Standard / Trane authorized dealer experts. Joseph, Chris, Michael and Natalia helped me and were very thorough and communicative and gave me top recommendations for my specific unit and situation.

I had a furnace installed by another company and the process was an absolute nightmare. Installation had several errors and issues that my previous company would not address. Oasis identified those problems and rectified all of them. They were able to explain how the system works to me and provide best steps forward.

I will only be using Oasis going forward. Highly recommend.

Response from the owner:Thank you, Luke! We're glad to hear about your positive experience with our team. Joseph, Chris, Michael, and Natalia truly appreciate your kind words. We're committed to providing the best service possible and are happy to have earned your trust for the future.
