Customer Reviews

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.

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 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.

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 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.

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.

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!

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!

Kerrie

Been using Oasis for twice a month routine maintenance on my ac/furnace unit and they always are prompt, friendly and have it running great. Prices are reasonable.

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.

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!

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.

Michael Nolan

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. He made sure I understood what he was telling me and not rushing explanations.

Response from the owner:Thank you, Michael, for your kind words about Joseph's thorough assessment and his clear explanations. We're glad to hear you felt well-informed about your options!

Furnace maintenance revealed some issues and I decided new vs repair just made more sense based on age. Prices were in line with national averages for the model and installation fees. Oasis is always friendly, responsive and professional!

Patty Menke

Oasis has done preventive maintenance on my heater the last two years, and it’s been a very positive experience. Scheduling is easy, they are responsive, and have actual humans involved in the process! (I’m writing this on the heels of dealing with Xfinity, which was a nightmare). The technicians were right on time both times, nice people, and they do good work. Also, they didn’t try to sell me anything I didn’t need, which builds trust. I will use them again next year and in between if anything else comes up that’s in their wheelhouse.

Response from the owner:Thank you, Patty, for your wonderful feedback! We're glad to hear that your experiences with our team have been positive and that our technicians were timely and trustworthy. We appreciate your trust in us and look forward to assisting you again in the future!

Rick Rockwell

Our technician Chris was prepared and easy to work with, as we had two jobs for him. After an estimate, he worked us into his schedule for the next day. He was on time each day and very efficient in how he completed his work. These were both plumbing repairs.

Due to the good work by Chris, when heating season came we had this firm check our heating season. Naim did the initial work and gave us good advice. But several weeks later a leaky humidifier shut down our system. Joseph came out at no charge to get the system working again. There was no charge even though this company had not installed the unit, nor did they cause the problem. Would definitely recommend them to others.

Response from the owner:Thank you, Rick, for your kind words about Chris and his efficient work on your plumbing repairs; we appreciate your trust in us and are glad we could meet your needs! We are here for all of your HVAC and Plumbing needs!
