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 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 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 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.

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.

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.

Quality work and excellent communication. Reached out for service and they were able to come the very first thing the next day. Will be using them for all future HVAC needs z

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.

For many years Mike has been doing HVAC work on my buildings: good work, good price and keeps his word. I often call him for advice on building problems and referals to other companies.

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!

Response from the owner:Thank you, Wendy, for sharing your wonderful experience! We're glad to hear that Joe provided great service, and that you found value in our program. Your satisfaction means a lot to us!

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!

Robert Andrews

Ari Greebel

Excellent plumber. He arrives ON TIME and is very professional. The quality of work, efficiency and price makes me very happy. Will definitely be giving him all our plumbing work.

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!

Captain Stoeber

Quick service… Fair prices… Good work.

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!

Barbara O'Connor

As. Real Estate Broker, I only surround myself with the best service providers for my clients. Oasis is the best. Prompt, honest, competent pricing, and very professional. I highly recommend Oasis. You will not be disappointed.

Response from the owner:Thank you, Barbara, for your kind words and for trusting Oasis as your go-to service provider; we appreciate your recommendation and are glad to hear you had a positive experience! We're here for all of your HVAC and Plumbing needs!

Response from the owner:Thank you, Nathan! We're glad to hear you had a quick and fantastic experience with our team and the home warranty representative. Your feedback means a lot to us! 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.

Response from the owner:Thank you, Alan, for your kind words! We're glad our team was able to assist you promptly and that you found the service easy and helpful. Welcome to our preventative maintenance program! We're here for all of your HVAC and Plumbing needs!

Sean Gervais

Completely agree with all the 4/5 reviews. They were very flexible in scheduling the service around my schedule. Worked quickly to determine the issue with my HVAC. Gave me a thorough explanation of the issue. Since it seemed like a common problem they a repair ready at hand. Even did some additional clean up of my outside unit. Wonderful service!

Response from the owner:Thank you, Joshua, for your kind words about Oasis; we appreciate your feedback and are glad to hear you had a positive experience with our team! We're here for all of your HVAC and Plumbing needs!

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! We're here for all of your HVAC and Plumbing needs!

Response from the owner:Thank you, Chris, for your wonderful feedback! We're glad to hear you had a great experience with our team . We look forward to working with you in the future!

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!

Response from the owner:Thank you, Eric! We truly appreciate your kind words and are glad to hear you had a great experience with our team. Your support means a lot to us, and we look forward to serving you and your neighbors again!

Arlene Bunis

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!

Response from the owner:Thank you, Arlene, for being such a loyal customer for over 20 years and for your kind words about our staff and service; we truly appreciate your trust and support!

We have been using Oasis for years and they have always been prompt, professional, and friendly. Their last visit was no exception. We always recommend Oasis to neighbors when they need HVAC service.

Response from the owner:Thank you, Beau, for your kind words and for being a loyal customer; we appreciate your recommendations and are glad to hear our team continues to meet your expectations!

Angela Whittenhall

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.

Response from the owner:Thank you, Angela! We truly appreciate your kind words and are glad to hear that Fernando, Michael, and the team provided you with prompt and professional service. It's great to know you found our quote competitive and that we could accommodate your installation quickly. Your recommendation means a lot to us!

Response from the owner:Thank you, Philip, for your continued trust in Oasis and for your kind words about our team, especially Harvey and Serge; we appreciate your recommendation!

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!

Response from the owner:Thank you for your wonderful feedback! We're glad to hear about your positive experiences with our team and that the installations and maintenance went smoothly. Your support means a lot to us!

Parm Purewal

Harvi and Serge were professional, on time, and very helpful during my AC unit replacement. They explained everything clearly and made sure I had no questions. Oasis has been my go-to for HVAC solutions the past four years—always great service!

Oasis stopped serving my area but made an exception because their previous customers recommended them to me. They came out quickly for a diagnose which helped us a lot. They are not cheap but trustworthy.

Response from the owner:Thank you, Lin, for your kind words and for trusting us based on your friends' recommendations; we're glad we could help quickly and that you found us trustworthy.

Abdul aamir

Joel Kiedaisch

Craig and everyone at Oasis were a pleasure to work with. They responded to our online request right away, arrived when they said they would, and fixed the problem quickly. We've used them before and will do so again. Thank you.

Response from the owner:Thank you, Joel! We're glad to hear that Craig and the team made your experience positive, and we appreciate your continued trust in us.

John Adler

Before calling Oasis, I had another company inspect our non-working AC. They diagnosed the issue as a faulty furnace circuit board. Since we had a similar problem in the past and replacing the circuit board didn’t solve it then, I asked the technician if he was certain. Although he said he was confident, they couldn’t get the part in a timely manner.

So, I called Oasis—an authorized American Standard dealer—and their technician, Naem, quickly ruled out the circuit board as the issue. He identified a shorted Y1 wire instead and had it repaired in under 30 minutes.

Huge thanks to Naem! Oasis will definitely be our go-to mechanical contractor moving forward.

Response from the owner:Thank you, John, for sharing your experience and for trusting Oasis with your AC issues; we’re glad Naem could quickly (and correctly!) identify the problem and get everything sorted out for you.

Kevin Galligan

Great job as always! Thanks - Mary and Kevin Galligan

Response from the owner:Thank you, Mary and Kevin! We truly appreciate your kind words and support. Always a pleasure to see you, and we look forward to the next visit!
