Customer Reviews

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.

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.

Shane 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.

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 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.

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.

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 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.

Denise Lemanski

First time using Oasis Heating. They came out same day on a holiday weekend. Fixed my heater and corrected an issue we had with the Nest. Explained the issue clearly and what they did to fix it.

Katie Prochilo

Debbie Deyhle

Wonderful tech, Damir, who came out to solve the problem of my furnace. Excellent scheduling process and communication from the company.

Sidney Stewart

I can’t say enough good things about Oasis Plumbing, Heating & Cooling. They came out on a Saturday in terrible weather when every other company either wasn’t answering or was quoting outrageous weekend rates. My Nest thermostat wiring and furnace configuration needed attention, and they handled it quickly and professionally.

Naem, the technician, was on time, knowledgeable, and incredibly kind throughout the entire visit. He explained everything clearly and made sure the system was functioning perfectly before he left. The gentleman who answered the phone was just as impressive — respectful, accommodating, and genuinely helpful when I called in desperate need of assistance.

Thank you so much for coming through when it mattered most. You truly saved the day for me. Highly recommend! 👏🔥

Emily Porter

We had an incredibly smooth time with Oasis. Their turnaround time for both diagnostics/inspection and installation of our replacement furnace was very fast. 10/10 would recommend their services.

They also provided helpful tips and things to think about for future servicing.

Joseph, the technician, came over to do a maintenance checkup for our 1-year old furnace and to the replace the damper on our Aprilaire humidifier. Joseph replaced the humidifier damper and showed me how to do it myself. After Joseph inspected my furnace he pointed out a potential problem with the compressor. He said that the compressor was overheating and needed to be watched. I live in a condo and will recommend Oasis to my neighbors

Response from the owner:Thank you, Doug, for your wonderful review! We're glad to hear that Joseph provided you with great service and helpful tips. We appreciate your recommendation to your neighbors and look forward to assisting you in the future!

As soon as I called, Natalia picked up and immediately made things easy she was friendly, responsive, and helped me get an appointment without any hassle.

Jasper Covington

Choosing Oasis Heating for my furnace and HVAC replacement was one of the best decisions I’ve made as a homeowner in Chicago. From start to finish, the experience was outstanding—with professionalism and genuine care that truly set them apart.

The installation team was not only incredibly skilled but also took the time to ensure every detail was perfect. Their workmanship was remarkable and impeccable, from the initial removal to the seamless setup of my new system. I never once felt rushed—quite the opposite! They patiently walked me through every step and explained exactly what to expect, which made the whole process surprisingly stress-free.

The best part? Their quote was easily the most competitive and reasonable among all the options I considered. Anel, who headed up my project, went above and beyond to help me—listening carefully to my needs and recommending a solution that was truly better than anything else I found. He made sure I understood the benefits of the new system and didn’t hesitate to address any questions I had.

If you’re in Chicago and need HVAC work, I can’t recommend Oasis Heating highly enough. Their team, especially Anel, is professional, honest, and committed to making sure you get the best possible service and solution. Five stars all around!

Response from the owner:Thank you, Jasper, for taking the time to leave such wonderful feedback! We're so glad to hear that you had such a positive experience with our team, especially with Anel's support. Your satisfaction means a lot to us, and we truly appreciate your recommendation!

Jamie Berry

Fantastic service! The technician was very nice and educational and informative. He showed up 10 minutes early to the appointment as well and was efficient with my time. Would absolutely recommend to anyone needing any HVAC services.

Response from the owner:Thank you, Jamie! We're so glad to hear you had a fantastic experience. We appreciate your recommendation and hope to work with you again in the future!

Michael Beirne

Oasis installed our furnace a few years back and recently we've been experiencing some issues with a faulty flame sensor. Oasis listened to our concerns, diagnosed the issue, and implemented a fix professionally and economically. They made things right. We received amazing customer service from Natalia and Mike (the owner?) and the on-site technicians Damir and Amir were very thorough and patient describing the issue and potential causes as well as quickly implementing a fix. Oasis does customer service as well as any organization I've dealt with and I can highly recommend them for anyone looking for heating/cooling expertise. Thanks Oasis!

Response from the owner:Thank you, Michael! We appreciate your kind words and are glad to hear that Natalia, Mike, Damir, and Amir provided you with exceptional service. Our company strives to make lasting relationships with our customers, and we're so glad we were able to help you out! Your recommendation means a lot to us!

Fernando to the rescue. Oasis is a neighbor of mine and I had heard they were amazing. My furnace wasn’t working so I sent a request after hours and someone got back to me in minutes. Fernando was there at 7am and fixed everything. They are affordable and friendly. I’m was very appreciative of them coming so quickly as the furnace was for my business. I also signed up for the yearly maintenance and they are coming on Monday to do a cleaning. Thanks again.

Response from the owner:Thank you, Kristy! We're glad to hear that Fernando was able to assist you promptly and that you found our services affordable and friendly. We appreciate your trust in us for your business needs and look forward to working with you again!

Technician Joseph did a great job in assessing issues with a 25 year old furnace, A/C, & water heater. He was very detailed and thorough in explaining the different options I had with regard to repairing vs. replacing each of them separately or replacing all of them in one shot, while giving me the pros & cons of the different options.
