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 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.

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.

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.

Great experience with Steve and Amer, Oasis plumbers!! I had a leaky pipe that needed urgent attention and Steve and Amer arrived within an hour of me calling Oasis. They diagnosed the problem immediately, gave me a clear and honest estimate of the cost of repair and proceeded to complete the repair quickly and professionally. They were both extremely knowledgeable and took the time to explain each step of the process. I will definitely be calling Oasis for all my future plumbing needs. Everyone at this company is responsive, friendly, and knowledgeable. Thanks, Steve and Amer, for doing such an excellent job at such a reasonable cost.

Response from the owner:Thank you, Celeste! We're glad to hear that Chris made such a positive impression. Your recommendation means a lot to us and we look forward to working with you again in the future!

Keith Forshaw

I have had very good experiences with Mike and his team over the years at Oasis HVAC. A few years ago when we first moved into the house, another HVAC company provided maintenance to the system while disconnecting the overflow drain switch on the AC coil pan. Therefore the unit ran for days and flooded our downstairs DEN. Oasis saved the day, reinstalling the switch and fixing the system. Now our old system is 19 years old and makes no sense to pay $1,000 to fix it so yesterday we decided to replace it. Mike came out to look at the old central air and heating furnace unit which is in the upstairs of our bungalow. Seated horizontally, it was going to take a lot of work to get the old unit out and the new unit in. We selected the American Standard (highest rated in the industry a.k.a. Trane) 80K BTU 2 stage furnace/central air and an American Standard 3.5 ton 13 seer A/C unit outside. The team of 5 guys came out to install it just 4 days after signing the contract promptly at 7:00am and completed the entire job at 2:30pm. They had originally thought it would take a day and a half. I also elected the annual maintenance which they come out 2 times per year and will also cover labor, along with manufacturer's hardware warranty for 10 years. The units are EXTREMELY quiet, you cannot even hear them run. Especially being outside and entertaining the patio. My electric bills are also expected to decrease significantly. The 19 year old previous system originally purchased from Sears was costing an additional $400/month just to run in the summer to to mention the old freon was $220.00 per pound. I am VERY satisfied with Oasis HVAC, quality product, quality service, attention to detail, professional and courteous. They also don't change extra for after hours emergency maintenance and have been easy to reach in the time of need and arrive at the house in 1-2 hours after creating an appointment. Oasis HVAC comes highly recommended from a highly satisfied customer.

Response from the owner:Thank you, Keith, for your wonderful feedback and for trusting Mike and our team at Oasis with your HVAC needs over the years; we're delighted to hear about your positive experiences and are thrilled that you're satisfied with your new system! We look forward to continuing to work with you!

Martin Kehe

Oasis is an outstanding HVAC contractor. We've used them for our home since 2015 and they always offer quick, reliable service. On their recent AC spring maintenance call at our 2-flat they identified that both of our 13-year-old water heaters are were leaking and in need of replacement, as was one of our AC units. They scheduled the work in less than a week and did the 3 jobs in about 5 hours from beginning to end. We received a good price and the work was well done. We highly recommend Oasis!

Response from the owner:Thank you, Martin, for your wonderful review! We're grateful for your continued trust in Oasis and are glad to hear you’re pleased with our service and the recent furnace upgrade. It's been a pleasure to work with you throughout the years!

Oliver Batchelor

Amazing and efficient service. We’ve been using Oasis exclusively for eleven years. After purchasing a house with outdated mechanicals we’ve used them for several replacements and checkups. They are reasonable, friendly, and professional.

Response from the owner:Thank you, Rob! We truly appreciate your loyalty over the past eleven years and are glad to hear you’ve had such positive experiences with our service. Your kind words about our team mean a lot to us!

Romy Connor

I used Oasis for both a/c maintenance and a water heater flushing. Guys were on time and very professional! Fair quote on both services..and didn't try to upsell me on things others had tried to do-luckily I have a friend that's a plumber and said what was needed. Will definitely be calling Oasis for future plumbing needs! Appreciate the honesty. One other company gave me a ridiculous quote..for something I didn't need-won't mention any names-but all reviews mentioned how high their pricing was-do some research!

Response from the owner:Thank you, Romy, for your kind words and for trusting Oasis with your a/c maintenance and water heater flushing; we appreciate your feedback and look forward to assisting you with any future plumbing needs! We are here for all of your HVAC and Plumbing Needs!

We’ve been relying on Oasis for years to keep the two HVAC systems in our 2 flat running smoothly and reliably. It’s a great piece of mind to know that coolant levels have been checked and furnaces have been examined before each season.

Response from the owner:Thank you, Owen! We're grateful for your long-term trust in Oasis to maintain your HVAC systems. It’s wonderful to know that our services give you peace of mind.

THE BEST EXPERIENCE in my 68 years with a home repair. Replaced my central AC. I had worked with Oasis 6 yrs ago small project and was impressed so when this major repair came up I got a couple quotes and I cannot BE HAPPIER WITH MY DECISION to hire OASIS. GOOD HONEST PEOPLE. On time, polite, always informed, left my home better than they found it and an extremely reasonable price. THANK YOU to DAMIR, AMIR, AMAR and JASON and the owner MIKE and NATALIA.

Response from the owner:Thank you, Mary, for your wonderful review and for trusting Oasis again, this time with a bigger project! We’re glad to hear that our team provided you with such a positive experience. We appreciate your kind words and support!

Joseph was awesome in performing maintenance on multiple units!

Layne Turci

I have worked with Oasis twice before and both times they have been PHENOMENAL. They're quick, helpful, and actually care about what's best for you, not just what makes them the most money. The first time, my AC went out last summer right before this big heat wave. Every other tech I had out told me I would have to replace the whole thing, and they couldn't do anything for me until after the slate of 95+ degree days we had coming up. Some told me that it would cost thousands to fix my current problem. Oasis came out and 10 minutes later, my tech Damir tells me he's fixed my AC by replacing a part -- he carries a spare in his bag. So he's patched it for the summer -- a $300 solution when I was prepared to spend $8,000+. He also walked me through what was wrong with the system, what would need to be replaced eventually, and how to keep the AC going through the rest of the summer. I felt his price was very reasonable (he even took a little bit off because he misspoke when he told me the original price) and he was able to truly help me, not try to get more money out of me. So this spring, I called them to finally get the AC replaced. First, they came out to do the estimate and explained all the options to getting the AC up the 5th floor. They are very focused on making sure you have a good experience (when I suggested not craning it up all the way, they responded basically "no, that's silly, that would just cost you more money than you need to spend. We're not doing that"). They came out today and in the course of doing the work, found a previously undiscovered leak in the HVAC closet. They immediately called their plumbing team (Amer and Steve) who cancelled other calls to come and help. Amer and Steve thoroughly diagnosed the leak and fixed it fast. They spent almost an hour talking me through the issue and different next steps to get the mold dealt with. The AC work has been great so far -- the team had to move my appointment to Saturday to save me about $9,000 in fees to the city and have been very communicative about the change. TL;DR: If you need a plumbing and heating company, Oasis should be your first call.

Response from the owner:Thank you, Layne, for sharing your excellent experience with us! We're glad Damir could provide a quick and affordable solution for your AC, and we appreciate your kind words about our team's efforts to accommodate you on short notice. Your satisfaction is our priority! We are here for all of your HVAC and Plumbing Needs!

Lara Mack

Excellent thorough service. Friendly and trustworthy. Was able to tell me what would need fixing immediately and what can wait. Let me know what to expect over the next 5 years. Signed up for the annual service plan

MatthewJN

We hit furnace trouble on one of the coldest days of the year, and Oasis still got us in the same day—on-site within two hours of my call. Naem was our technician and was fantastic: kind, quick to diagnose, and had the heat running again in under 30 minutes. They also installed our rooftop A/C and did an excellent job. We’re really grateful for the whole Oasis team and their great service. Highly recommend them to anyone in Chicagoland. Update 4/23/26: our furnace worked great the rest of the season! Also wanted to add we just had our AC serviced today by Joseph at Oasis and he was excellent. Timely, helpful, and laid out repairs that would likely be necessary in the next couple of years. Great service and we’re thankful for making us aware of what to plan for in the future!

Response from the owner:Thank you, Matthewjn, for your wonderful review! We're so glad to hear that Naem provided fantastic service and got your heat running quickly. Your recommendation means a lot to us, and we appreciate your support for the entire Oasis team!

Hayley Gebhardt

Great experience with Osais! very professional and helped me understand the problem. they fixed everything perfectly. I will be calling them again!

Response from the owner:Thank you, Hayley! We're glad you had a great experience with Osais and that our team was able to assist you effectively. We look forward to helping you again in the future!

Susan Pachera

AC service: Joseph was very friendly and efficient. He kept me updated on the work he was doing. I’ve used Oasis for years and am always impressed with their professionalism. Very reasonable prices on the HVAC services. Prior review:The work was done quickly and plumber was nice but quite expensive for a short job so I’ll go back to my previous plumber

Response from the owner:Thank you, Susan, for your feedback! We're glad to hear the work was done quickly and that you found the plumber nice, and we appreciate your honesty about the cost. We hope to still work with you for all your HVAC needs!

Krystle Reavy

The best service every time.

Response from the owner:Thank you, Krystle! We appreciate your kind words and are glad to hear you consistently receive the best service.

Jonathan C.

Special recognition goes to Hani, and the technicians Damir, Amir, and Vaha. Incredibly efficient at the task, for the thorny HVAC installation. Amir assured me the most capable crane guy is coming to lift the AC to the rooftop through the trees. What was scheduled to be a full day project finished before noon after all testing. Especially Hani was different from our first meeting - he explained all the components clearly in a way that a layman can understand and I appreciated taking his time to walk me through his thought process and how he arrived at his proposal. It takes thorough experience on the actual job as a technician and leveraging that to face clients. Friendly guy and easy to talk to. After the task was done, his follow up service was top notch. This review can only do so much to help them. I’m glad to be part of the effort supporting their business.

Response from the owner:Thank you, Jonathan, for your thoughtful review! We're glad to hear that Hani and our technicians, Damir, Amir, and Vaha, made such a positive impact during your HVAC installation. It's great to know that Hani's clear explanations and friendly approach enhanced your experience. We truly appreciate your support for our business!

Patrick Huurman

Scheduling was great, but the service itself was lacking: technicians did not complete the task before leaving, instead offering a confusing explanation that was not true upon further research. They left my house for ~30 minutes to get equipment and let themselves back in - no knocking or courtesy text. Upon trying to have my task completed, I’ve been met with near radio silence. I had such high hopes based on the service prior to my actual appointment.

Michael

Joseph was fabulous. On time, thorough, and very informative. Since we just moved in, he was especially careful to make sure we understood how this particular system worked, the required maintenance for it, and potential upgrades or repairs down the road. Best HVAC technician we’ve ever had.

Response from the owner:Thank you, Michael, for your wonderful feedback! We're glad to hear that Joseph provided you with such thorough and informative service, especially as you settle into your new home. We appreciate your kind words about him being the best HVAC technician you've experienced.
