Customer Reviews

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.

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.

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 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.

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!

Brian 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.

Sharon OBrien

This is a highly trusted business. I've worked with them for the past 10 years and they are absolutely, hands down one of the best customer focused businesses I've come across.

I had an issue with my A/C recently (during one of those 90+ degree nights) and called to leave a message for the morning.......the owner of the business Mike Causevich answered my call and walked me thru what to do to fix my system without them having to come out.

I give them my highest recommendation.

Patrick McEneely

Oasis came out and serviced my furnace in an emergency situation and handled the issues with the utmost professionalism. I have worked with many companies and tradesman over the years and Oasis is different, they are prompt, courteous, professional and extremely knowledgeable about what they do. They are honest too and fair in their leaving. This is the best HVAC company in Chicago in my opinion.

Response from the owner:Thank you, Patrick, for your kind words and for trusting Oasis with your emergency furnace service! We truly appreciate your recognition of our team’s professionalism and knowledge. Thank you so much for your support and recommendation!

Rebecca Brokmeier

Great service, resolution and timely!

Response from the owner:Thank you, Rebecca! We appreciate your kind words about our service and are glad we could resolve your issue promptly. We appreciate your trust in us!

Dru Shockley

Oasis did a stellar job. Always nerve-wracking when a furnace goes out, especially in winter. They gave me a fair price, came out immediately, and performed a great installation. Also very courteous and professional. They've locked in my business as my multi-flat has other aging units. I just hope to space it out significantly. Thanks, Oasis!

Response from the owner:Thank you, Dru, for your wonderful feedback! We're glad to hear you had a positive experience with our team and appreciate your trust in us for your future needs. We're here whenever you're ready for your next project!

José Luis López

Response from the owner:Thank you, José, for your amazing 5-star rating; your support means a lot to us!

John MacInerney

I called Oasis last Saturday morning, due to a noisy, rattling furnace. The owner, Mike took my call, and came to my house in about 25 minutes. He knew right away that a fan’s bearings required the fan to be replaced. He picked up the replacement fan that morning and had a very competent technician, Jason, replace the fan on Monday. I highly recommend Oasis- the whole transaction was seamless.

Response from the owner:Thank you, John, for your fantastic feedback! We're glad Mike was able to assist you quickly and that Jason provided you with great service. We truly appreciate your recommendation!

Aaron Feigenbaum

I had a great experience with Oasis. Mike arrived within two hours of my service request, diagnosed the issue quickly, and had it fixed in no time. What stood out was his willingness to explain the problem and how to prevent it in the future, along with offering helpful insights about my furnace and HVAC system. No upselling, just straightforward and knowledgeable service. Would definitely recommend.

Response from the owner:Thank you, Aaron, for your wonderful feedback! We're glad Mike could provide you with prompt and informative service. Your recommendation means a lot to us!

Chris was great! Very professional and attentive. He walked us through exactly what was going on with our hot water tank and was able to exchange it for a new tank. There is no doubt we will continue to use Chris and Oasis in the future!

Devon Freeny

The twenty-year-old furnace in my condo finally died just before the last big cold snap. On a recommendation from a friend, I called Oasis and they were able to replace the entire system within twenty-four hours. Technicians Damir, Amir, Amar, and Harvey were not only fast but also courteous and careful, leaving no debris or anything out of place and the system working perfectly.

Response from the owner:Thank you, Devon, for your wonderful review! We're glad to hear that our team, including Damir, Amir, Amar, and Harvey, provided you with excellent service. Your satisfaction is our priority, and we're here if you need anything else!

Judith Piccione

We had Oasis come to our house to service and evaluate our 3 furnaces. They are 30 year old Lennox brand. They found them to be in perfect working order and didn’t try to upsell us. I also asked for the replacement cost when the time comes. Their prices are very reasonable and the technician was very knowledgable and profession and polite. I highly recommend because you can trust them to tell you the truth and give an honest opinion and pricing.

Response from the owner:Thank you, Judith, for your kind words and for trusting us with your furnaces; we're glad to hear our technician provided you with honest service and valuable information. We hope to see you again soon!

James Keating

Service tech was professional and knowledgeable about solving furnace problem. 100% recommend the company for service.

The entire team came to install a furnace, water heater, and AC. What a professional crew, Vaha, Abel, Harvi, and Amir. The work preformed was exceptional and done without any inconvenience. This Company knows how to serve their customer with professionalism. Job well done!

Response from the owner:Thank you, James, for your kind words about our technicians; we appreciate your recommendation and are glad we could help! We hope to work with you again soon!

Tim K

Competitive price from a great locally owned and operated company. Had a new furnace instead fast and without issue

Response from the owner:Thank you, Tim! We're glad you found our pricing competitive and that your new furnace installation went smoothly. Your support for our locally owned business means a lot to us!

Brighid Martensen

Chris is one hell of a plumber. 100% knows his stuff, is efficient, and is willing to explain multiple times for people who don't know jack about plumbing!
Fixed a broken valve under my kitchen sink, and because of how old my building is, there was a blockage that formed that tanked the water pressure. He came back, helped us identify the problem, and now we know how to fix it!

Knowledgeable, experienced, came out fast, fixed the problems even faster. Cannot recommend enough

Response from the owner:Thank you, Brighid, for your kind words about Chris and for sharing your experience; we're so glad he could help you and provide guidance! Your recommendation means a lot to us, and we hope to see you again soon!

Cady Bruzan

We had a high efficiency furnace installed two months ago. I noticed a puddle in the basement and reached out after hours to Oasis. I texted with their AI chat bot assistant and had an appointment confirmed for the next day within just a few minutes. Jason showed up promptly at the appointment time, assessed the unit, got the required part and completed the install within an hour. He was helpful and professional and made this repair an absolute breeze to resolve.

Response from the owner:Thank you, Cady, for your kind words! We're glad to hear that our new AI chat bot and Jason provided you with quick and professional service. Your satisfaction means a lot to us and we hope to see you again soon!

Anneliese Goetz

Chris came to work on our plumbing and was excellent! We had a mysterious clog for months that our own attempts at routing hadn’t cleared. He came in, helped diagnose the issue, and then fixed it. The job ended up being more involved, but Chris ran out right away to get parts and had a whole piece replaced and working within a couple of hours. We felt the price was reasonable both for the time, parts, and work. We will definitely call them again!

Response from the owner:Thank you, Anneliese, for your kind words and for recognizing Chris's efforts in resolving your plumbing issue; we're glad to hear you found the service timely and reasonably priced, and we look forward to assisting you again in the future!

Courtney Smith

I believe this is the second time I’ve used this company. Always a pleasant experience. Scheduling was super easy and fast! My Tech, Naem, was professional and took the time to explain things to me and show me how to clear the pipe. He didn’t BS me or try to sell me anything. Would recommend and use Oasis again and again. Thank you!

**Update: Jason serviced my furnace. Was quick and efficient. Fast service from the company. Requested a maintenance yesterday and was scheduled today at 8:30 AM.

Response from the owner:Thank you, Courtney, for your kind words and for choosing us again! We're glad to hear that Naem provided excellent service and that Jason was efficient with your furnace maintenance. We appreciate your recommendation and look forward to serving you in the future!

Response from the owner:Thank you, Emily! We're so glad to hear the crew made your experience pleasant (and quick!). We hope to work with you again in the future!

Katrina Ta

Mike responded quickly and luckily was nearby so came over pretty fast as well. He was off the clock but still came because I wouldn’t have heat on that cold winter night if my furnace didn’t get fixed. He also explained what went wrong and gave me some tips in case a similar situation occurs in the future. Was reasonably priced as he didn’t charge for the new fuse, overtime, etc. Will definitely use Oasis again for future HVAC needs!

Response from the owner:Thank you, Katrina, for your wonderful review! We're glad Mike was able to assist you quickly and provide valuable insights. Your support means a lot, and we look forward to helping you with your future HVAC needs!

Liza Belle

Quick service! My furnace stopped working. Put in a request for a quote one evening. Hani came out the next day for the quote and sent a team out the following day to replace my furnace. Positive experience. Will be using them in the future.
