Customer Reviews

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 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.

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 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 came through for us when our furnace went out in the middle of the night this January while our dog sitter was here and we were out of town. They showed up within 8 hours and installed a part to get it through the weekend until they could come back for the full replacement. A few months later, Damir returned to help install a new thermostat when the old one started acting up. Overall one of the better experiences I've had with a service company in my 10 years in the city. Hats off to the Oasis team, and thanks again to Damir.

Response from the owner:Thank you, Dan! We're glad we could assist you during such a crucial time and appreciate your kind words about our team. We'll be sure to pass along your thanks to Damir as well. Your positive experience means a lot to us!

Update: During our AC maintenance appointment, the team discovered a severe leak. Once again, the technicians were incredibly kind and informative, walking us through all our options and the associated pricing. Since the unit is 12 years old and had not been properly maintained before we purchased the home, we decided to replace it. They scheduled the replacement for the very next day, refunded our maintenance fee, and provided a very fair quote that was on the lower end of what we found in our research. I truly cannot recommend this company enough! I feel so much better knowing our entire HVAC system was installed by their team and will continue to be maintained by them annually. —— Such a great experience! Learned about them through referrals in Lakeview. We closed on our apt on Tuesday. I was able to have someone come out on a Wednesday to check out the furnace and dehumidifier. The team was able to replace everything by Friday. I was nervous about up charges with the cold weather just kicking off, but instead, Oasis gave me a discount and helped bring everything up to code (for free or extremely low costs). Highly recommend! I will be purchasing their 2x a year services too. The guys were such gentlemen, on time and super clean. Thank you!!

Response from the owner:Thank you, Autumn! We appreciate your kind words and are glad to hear you had a great experience with our team. We look forward to serving you again with your biannual services!

Joseph came, explained everything I could've needed to know, showed me pictures of the clog, cleaned it out, couldn't have been easier. This is the furnace they installed 10 years ago, we haven't had any issues in 10 years, and this would have been prevented of we got regular services! Happy to support this local company and they do great work. Summer '26 update. Fernando and Joel installed a new AC unit as ours was over 20 years old and started making lots of me noises. Reasonable price, quick service, the unit has been working great for a few months now.

Response from the owner:Thank you, John! We're glad to hear that Joseph provided you with such thorough service and that your furnace has been performing well for a decade. We appreciate your support of our local business and look forward to continuing to serve you!

The Oasis team is super responsive and their expertise in ductless/heat pump systems was critical. They remedied errors in our original installation (done by our former general contractor) and now our heat pump system is working great.

Response from the owner:Thank you, Steven! We're glad to hear that the Oasis team was able to assist you and resolve the issues with your heat pump system. Your satisfaction means a lot to us!

Oasis is very helpful and quickly responds to issues. I appreciate their fair and honest approach - they will tell us when problems are associated with systems that they install/repair and when they are not. I greatly appreciate the candor.

I gathered quotes from two other area HVAC companies for an a/c install. Feeling frustrated and let down with our uncertainty of how necessary this was, we saw an Oasis truck pull up beside us on our drive home. I looked them up and they had great reviews so we scheduled an appointment with them. Eb did the assessment and said he had been working with the company for over a decade, came and diagnosed our issue (same as the two others/best option for our old system was a replacement). He explained what was going on better than anyone else and answered all my questions. Install was done today! Thanks guys! Honest & dependable work!

Response from the owner:Thank you, Erin! We're glad you found us and had a positive experience with Eb's assessment and installation. Your feedback about our honest and dependable work means a lot to us!

Response from the owner:Thank you, Linda! We're glad to hear that the technician was punctual, polite, and able to provide you with valuable insights about your AC unit. It's great to know that scheduling was easy for you as well. We appreciate your recommendation!

Tom Quintero

Called to fix a common evaporator drain issue. The tech seemed to do an adequate job however the water from the evaporator continued to drain inside my house. Called again, another tech came and he said I was good to go. Still I had water leaking in my house. Called another company and this time the tech did a fantastic job. Actually fixed the problem! Guess which company I’m using to replace my entire system?

Response from the owner:Hi Tom, we’ve searched our records but haven't been able to match your review to a customer in our system. We take feedback seriously and would love the opportunity to learn more about your experience and see how we can make things right. Please give our office a call directly at (773) 320-5395 at your earliest convenience.

Master plumber Steve was extremely knowledgeable, skilled and friendly. He went the extra mile on my service call to troubleshoot and make sure my new shower trim handle was installed. He left the place looking better than before and explained everything to me in detail so I could understand my shower plumbing better. I also had a good experience talking with the support team and GM Josh.

Response from the owner:Thank you, Nick! We appreciate your kind words about Steve's expertise and the extra effort he put in during your service call. We're glad to hear you had a positive experience with the support team and Josh as well. Your satisfaction means a lot to us!

Pedro Gomez

Not the best estimate, pricy for one stage AC installation, the guy who came is nice but still charged for 120$ supposedly for tune up or cleaning but what happened is installation estimate which is just free for other companies.

Response from the owner:Hi Pedro, our team left you a voicemail earlier regarding your service. Since the maintenance was not performed, a full refund is being processed for you. Thank you for letting us know so we could get this corrected.

Oasis was really professional and friendly. They came by for maintenance on our AC units and immediately realized we were low on coolant. They topped us up and didn’t charge for the full amount they used. And their member program is a great deal. You get a discount on maintenance by signing up for reminders, no annual or monthly fee. You get a benefit for something you should probably have anyway, reminders for annual servicing. Will definitely use again!

Response from the owner:Thank you, Philip! We appreciate your kind words about our professionalism and friendliness. It’s great to hear that you found value in our member program and enjoyed the service. We look forward to assisting you again!

Mary Montgomery

Very friendly and helpful arriving on time. Explained the problem with the AC unit and detailed the process for repair. They will send us an estimate, and we shall proceed from there. Thank you!

Response from the owner:Thank you, Mary! We're glad to hear that you found our team friendly and helpful. We appreciate your patience and look forward to getting your AC unit sorted out.
