Customer Reviews

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.

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.

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 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.

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 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.

Oasis is a first class HVAC company. Oasis installed a new MagicPak unit for my condo in River North 1 year ago. Oasis completed the 1 year service as well. All of the services that Oasis provided were excellent. This includes system knowledge, system installation, office notifications for progress updates, check-ins for satisfaction responsiveness and price. If you need a new system, system repair or annual system service Oasis is your best choice!

I have had Oasis for HVAC maintenance & repairs in the past. This time I had a broken garbage disposal. Chris was very prompt & explained the problem.

Scott Allen

The Oasis crew replaced our HVAC system including AC compressor in just over half a day. They did a fantastic job - delivered what was promised - install looks neat and tidy. They had to get the AC compressor onto the roof of our 3 story building. The crane operator they used was quick and professional. I would recommend Oasis for maintenance and installs of HVAC systems. Great company to work with!

Riti Sobilo

In my 10+ years of living in Chicago, I have had unpleasant experiences being upsold to and mansplained at about HVAC systems. Chicago weather can be so dramatic and that does take a toll on the systems, but I can confidently say the folks at Oasis are the best. Their engineers are super knowledgeable and kind (shoutout to Danny for being our go-to). Their maintenance package makes everything easy and is fairly priced. Their communication / customer service is great. They are an ultimate ally in homeownership.

Response from the owner:Thank you, Riti, for your kind words and for sharing your experiences with us; we're glad to hear you feel supported by our knowledgeable team, especially Danny, and appreciate your continued support!

Response from the owner:Thank you, John, for your kind words about Mike's work and reliability; we appreciate your trust and are grateful to be able to work with you!

Wendy Travers Chao

Great experience, from making the appointment to having my air conditioner fixed this morning. The technician (Joe) was prompt, kind, efficient & knowledgeable. He explained my options and everything was resolved to my satisfaction. I signed up for their special service package, which was free and ended up saving me money!

kathy 53954

A great experience with Oasis from start to finish. When my AC died Mike himself came the next day (Sunday morning) with a short term fix. Installation of new AC and furnace Tuesday afternoon by Anel and Vaha was a pleasure - prompt, professional, skilled, and very responsive.

Response from the owner:Thank you, Kathy, for your wonderful feedback! We're glad Mike could assist you promptly and that Anel and Vaha provided a great installation experience. Your satisfaction means a lot to us!

Kevin Burrows

Had a great experience with Oasis replacing my 20+ year-old AC and furnace. Mike (owner) personally came to quote a new system (at a 20% savings compared to ABC), and was able to schedule next-day installation.

The 3-man team did a great job creatively working through space constraints and had the new system up and running in no time. They even installed 3 new smart thermostats at no extra cost. Would highly recommend Oasis for your HVAC needs.

Response from the owner:Thank you, Kevin, for your fantastic review! We're glad to hear you had a great experience with Mike and our team during your AC and furnace replacement. Your recommendation means a lot to us!

Response from the owner:Thank you, Ari! We're glad to hear that you appreciate the professionalism and quality of work. We look forward to assisting you with all your plumbing needs in the future!

Steven Shay

Our A/C stopped working during a heat wave and we called Oasis after having mediocre experiences with other providers in Chicago. They were able to come out in less than 24 hours and diagnosed that we just needed to clean our outdoor units and replace our filters. After doing that, magically everything worked and we had cool air again. They didn’t try to upsell us or repair something that doesn’t need to be repaired. Love their honesty and we’ll use them again.

Response from the owner:Thank you, Steven, for your kind words and for choosing Oasis; we're glad we could help get your A/C back up and running quickly. We appreciate your trust and look forward to serving you again! We're here for all of your HVAC and Plumbing needs!

Haotian Li

Oasis helped me replaced the AC cooling system. They are super professional and patient with all my installation question. Will definitely work with Oasis in future.

Response from the owner:Thank you, Haotian, for your kind words! We're glad to hear that our team was professional and helpful during your AC installation. We look forward to working with you again in the future! We're here for all of your HVAC and Plumbing needs!

Response from the owner:Thank you, Captain, for your kind words about our quick service and fair prices; we appreciate your support and are glad you had a great experience! We're here for all of your HVAC and Plumbing needs!

Jamieson Mulholland

Set an appointment for 10am. At 10:20 they let me know they would be an hour late. Changing my plans, I found someone to come and let them in. They must not have pushed the doorbell all the way in, since the person in the house did not hear them. I missed a call from them at 11, but called back within 10 min. They had already moved on, canceled my appointment, and refused to come back the same day. Definitely frustrating and hypocritical after making me wait around all morning. Not nice when your air has been out for multiple days in the heat of the summer.

Kevin McLean

Best possible way to do home repair if you can't do it yourself for free. Thanks guys!

Response from the owner:Thank you, Kevin! We're glad you found our service helpful for home repairs, and we appreciate your shout-out to the team! We're here for all of your HVAC and Plumbing needs!

Alan Lewis

Our A/C went out. They were able to come the same day (Sunday) and have a look. They figured it out within 5 minutes and said they could be back the next morning. They came back on time and made the repair. Easy as can be and both techs were extremely polite and helpful. I signed up for their preventative maintenance program.

Maura Barrett

I had a really positive and efficient experience with Oasis. The quote was easy to schedule as was the work that needed to be done. The team was very flexible with a few different proposals, and helped me troubleshoot an issue that came up when my HOA was being difficult about where the condenser could be placed. Their creative solutions were immensely helpful and got us much needed air-conditioning just before the summer heat waves. They also caught an issue that my electricians made, which saved a lot of headache in the future for other projects and to make sure that my unit would stay healthy.

Response from the owner:Thank you, Maura, for your wonderful feedback! We're glad to hear that our team was able to provide flexible solutions and assist with your HOA challenge, ensuring you got the air-conditioning you needed. Your satisfaction means a lot to us!

Eric Yore

I was extremely pleased with my experience with Oasis! From the prompt scheduling to the expert service, an all around great experience. I had a 10:00 am appointment and the tech was running late. He had the courtesy to call and let me know he would be running late. Little thing, but much appreciated! Makes a huge difference. When he arrived he was very professional, knowledgeable, and completed the work in a timely manner. I will continue to use and recommend Oasis. I’ve had neighbors use Oasis as well, and they have also been pleased. Thanks!

I have been an Oasis customer (and fan) for over 20 years! I have only experienced the BEST service and professional care for all these years - their staff is excellent (and everyone has been there a long time so my experts keep coming back year after year). I feel known by their staff which gives me great peace of mind when they arrive to do a job…I know it will be done correctly, thoroughly, quickly, promptly and efficiently - and with a warmth and kindness that leaves me smiling. The consistency is so appreciated. I would never use anyone else!

Oasis did an amazing job replacing my 20 year old HVAC unit today. Fernando, Michael, and their team were prompt, professional, friendly, and efficient. The office was also great to work with and scheduled me for installation the next day. Their quote was the most cost friendly of the several I received. Highly recommend.

A Ho

This company is incredibly responsive and professional. They installed two new furnaces and AC units in 2021 in our home. This wasn’t the easiest with one of the furnaces in the attic. They did an excellent job and the units have been working really well. Today, they did some maintenance service on the furnaces and again were friendly, super helpful and very knowledgeable. This is a great company to work with!
