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.

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.

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.

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.

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.

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.

Oasis responded quickly. The nicest man came out at 7am to check out my system. And then another super nice person came out at 12:30pm, part in hand to fix my system, saving me from having to replace my furnace. Both people were kind, professional, and worked quickly. I’ll be using them again, for sure!

Response from the owner:Thank you, Rina! We appreciate your kind words about our team and are glad we could assist you promptly. We're looking forward to helping you again in the future!

Demir from Oasis was GREAT. Accommodating and figured our issue out QUICKLY. I could tell he had been doing this a long time. He also trouble shot the part that was the issue BEFORE COMING. This was great as he assessed and fixed quickly.. He climbed up a 23 foot ladder to take care of the work. I have used Oasis for the last 13 years. Highly recommend.

I've used Oasis multiple times and each time their service has been excellent. I've used them to replace an A/C and electric furnace in my condo, replacing the gas furnace in my house, and most recently replacing the A/C in my house. I've also used them for regular system checks and diagnostics. What really sets Oasis apart is the personal accountability from the top down. The owner, Mike, has personally stopped by to make sure everything was handled right, and he genuinely goes above and beyond to meet your needs. The best example was when my A/C went out right at the start of a Chicago heat wave. Instead of putting me on a long waiting list like other companies would, Mike helped expedite a fast replacement to get the house cool again right away. Between handling the condo, the house, and dealing with unexpected breakdowns, they have never let me down. They even seamlessly followed all the strict rules and scheduling requirements set by my condo association. Their prices are very reasonable, they are always punctual, they don’t try to upsell you on things you don't need, and they leave the place clean. Finding an HVAC contractor in the city you can actually trust is tough, but Oasis has absolutely earned my repeat business.

Response from the owner:Thank you, Eric! We truly appreciate your loyalty and kind words about our service. It's great to hear that Mike and the team have consistently met your needs and provided reliable solutions. Your trust means a lot to us, and we're here whenever you need us again!

I am Patrick’s tenant - we worked with Joseph when we had an issue with our upstairs neighbor’s AC unit leaking though our wall. He was kind, attentive and answered all my questions in a way that made sense to a girl who knows nothing about HVAC! He is awesome!

Response from the owner:Thank you, Sam! We're glad to hear that Joseph was able to assist you with your issue and that his explanations were helpful. We appreciate your feedback!

Really happy with my experience with Oasis. Great communication and response with scheduling. I had a full hvac replacement and my specific install team of Fernando, Amir, and Joel were great. They arrived on time, professional, respectful, and took the time to answer all of my questions. They explained everything clearly, which made me feel confident throughout the installation. They also set up my new Nest thermostat wiring and walked me through the complete set up & capabilities. They made sure everything was working properly before they left.

Response from the owner:Thank you, Karrie! We're glad to hear about your positive experience with Oasis and appreciate your kind words about Fernando, Amir, and Joel. It's great that they were professional and took the time to ensure you felt confident and informed. Enjoy your new HVAC system!

The response time to set up and have a service technician come out to look at and fix our AC during a heatwave was amazing! Danny could not have been more professional or pleasant. Oasis is now our new HVAC go to for maintenance and service.
