Customer Reviews

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.

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.

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 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.

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.

Oasis Heating and CoolingExcellentOasis Heating and Cooling4.9 Based on 561 reviews fromSee all reviews review us onDonna CalvertDonna Calvert ★★★★★ We’ve been using (and recommending) Oasis for years, both at our current new place and our old place. Our air conditioning stopped working yesterday. Naheem showed up early this morning as expected, quickly identified and resolved the problem, and made sure everything else was working well before he left. He was polite, friendly, knowledgeable and capable - which is standard for Oasis. Highly recommend.Mike VeldhuisMike Veldhuis ★★★★★ Quick response time! Also, the person that showed up was super nice and full of knowledge. Thanks for troubleshooting and solving the problem….enjoying a cool house againNina BembenNina Bemben ★★★★★ I will always call Oasis Heating and Cooling first from now on! My air conditioning stopped working during a heat wave and after being told I needed a whole new furnace unit, and that I probably should replace the AC too, I decided to call Oasis to compare quotes before spending $8000+. Oasis was able to come the next day, and was able trouble shoot. I went from needing to replace an entire HVAC unit to paying a service call for a blown fuse. I truly appreciate the honesty and professionalism of Oasis!Matthew DuffyMatthew Duffy ★★★★★ Eric RoutenbergEric Routenberg ★★★★★ Incredibly responsive on a Saturday at the start of a 3-day heat wave. They were able to come out the same day a few hours after I called and they quickly diagnosed what was wrong with one A/C unit not blowing cold air (it wasn’t what I thought it was). The technician fixed the problem (dead capacitor) and performed a full cleaning and check up on both A/C units’ condensers and coolant charges. He took before & after pictures of everything and explained each issue to me during the process – – very reassuring. Expensive, but if you ask for a discount, they were friendly about obliging.Professional, polite, articulate, and thorough.Will DavisWill Davis ★★★★★ Mike & Aiden came out to assess what others had diagnosed as an uncharged condenser, missing wires, and a faulty thermostat. The root cause of the issue was quickly identified, a solution was agreed upon that got our A/C running immediately, and the work was completed timely. It was a HOT day and these guys battled through it. I was tired of the run around from other vendors and glad we found someone we could trust. Thanks again.Stephanie MorettiStephanie Moretti ★★★★★ Fast friendly and reliable service! I had a diagnostics testing Friday afternoon (the 12th) and they were able to install my new fur nance and a/c first thing Monday morning the 15th. They were right on time for both visits! Highly recommended!Carl FritscherCarl Fritscher ★★★★★ Excellent Company, Great Service. I had a central AC unit crap out the night before a heat wave. I called at 10:30 at night - they answer the phone 24 hours - and chose not to have emergency service but Mike called me at 7:04 in the morning to schedule a time THAT SAME DAY to repair my unit. He came out at 9:30 am, diagnosed it right away, and brought the right part with him "because it's usually this part" to make a fast repair. Fast, simple, done. Plus Mike is about the nicest guy you can meet when you are stressed out about the potential of an unforeseen major repair.Kieran CaseyKieran Casey ★★★★★ Tina DekkerTina Dekker ★★★★★ Oasis has been my go to for all of heat and AC needs for more than 10 years. Always reliable and courteous. They take time to help me understand what I should do myself between maintenance visits. Thanks especially to Damir for coming out today on short notice in the high heat! All sorted in 30 min.John KulkaJohn Kulka ★★★★★ kyle kaufmankyle kaufman ★★★★★ The guys did a great job! Were timely and installed a new ac and heat system for me! They had the best rates for a reputable company and I felt comfortable with Mike the owner from the beginning! Highly recommend!Response from the ownerThank you so much for the great review, Kyle! Mike will be glad to know you had such an incredible experience, and we look forward to helping maintain this system for years to come! Adam SheradenAdam Sheraden ★★★★★ Last week my AC condenser finally gave out and I called Oasis to get an estimate on replacing the unit. My water heater and furnace had also been on my mind to replace this year, and Oasis was able to quickly give me an estimate, to tweak it slightly to meet my request for increased energy efficiency, and were able to install all 3 pieces of equipment and test them in 1 day. I had a great experience working with their team, including Damir, who advised on what equipment types were ideal for the space I had available, and Vaha and Anel, who made sure the installation was smooth, clean, and helped configure my new thermostat as well. There was a minor fix needed to complete the work, and they came back quickly the next day to resolve it. I spoke to the owner, Mike, several times throughout the process and he was always quick to pick up the phone and respond immediately to make sure things were going well. Would definitely recommend working with Oasis.Response from the ownerThank you so much, Adam! We are more than happy to work to meet our clients needs, and glad to offer a quick turn around. Mike, Damir, Vaha, and Anel were all happy to help, and will be thrilled to read your kind words. We are glad you let us come back to finish things up, and hope to work with you again this winter for any preventative maintenance. Jacob FJacob F ★★★★★ Great service!!!

Great crew.Response from the ownerWe were so happy to work with you, Cynthia! I feel I should note that I'm Lydia from the office, and you really did make our day. You were so incredibly kind and understanding, even with the bumps in filling out the forms. We're glad you of all people could have such a good experience, and we truly hope we can continue to work with you for years to come. You are such a thoughtful person, and we are so happy to be able to work with you!😀 Noel FlanaganNoel Flanagan ★★★★★ Came and let me know what needed to be done with the AC to get it sorted.Response from the ownerThank you, Noel! We are happy to offer such a speedy solution! J SJ S ★★★★★ I had 3 heating and cooling companies visit my property and Oasis was the most professional! They provided a quote right away, worked directly with my HOA, and got the job done within 2 days of signing the estimate. Very happy with my decision to proceed with Oasis!Response from the ownerThank you so much! We know every HOA is different, and we are glad we could get the paperwork figured out so quickly. Thank you so much, and we hope to work with you again this winter! María Hernández V.María Hernández V. ★★★★★ Response from the ownerThank you, María! Kit CudahyKit Cudahy ★★★★★ I highly recommend Oasis. I needed a lot of work done and they handled the job beautifully from start to finish. They came out initially and guided me through the process. They had workers out the following day to complete the job since the weather is getting warmer. And everyone they sent was friendly and lovely. I feel grateful I found themResponse from the ownerThank you so much, Kit! We like to make sure we can educate our clients so they can make the best decision possible. You were just as lovely, and we were happy to work with you! We hope we can help you with preventative maintenance this winter! Tarik GalijasevicTarik Galijasevic ★★★★★ Awesome service. Very professional. Super knowledgeable and super fast. Responded quickly and Mirsad was on site in no time going thoroughly through potential issues. Once he was done, he presented me with all the options and together I was able to pick a solution that worked the best for me. I highly recommend Oasis heating and cooling out of Elmhust locationResponse from the ownerThank you so much, Tarik! Mirsad really is the best, and will be glad to see you agree. We like to make sure our clients have all the resources to make the best decision, and we're glad to know this solution worked as well as we knew it would. Thank you, and we hope you keep us in mind for preventative maintenance. Stacie LStacie L ★★★★★ My A/C unit was ancient and as usually happens, sprung a leak two days before a heat wave hit. I emailed on Thursday night not expecting a response until Friday but Mike responded within a few minutes, Naem was at my place on Saturday morning, and Fernando and Mike installed my new unit on Monday.My experience with everyone was fantastic and impressed is an understatement. My furnace is equally ancient and I’ll be calling Oasis and would not hesitate to recommend that you do the same!Response from the ownerThere's nothing more frustrating (and more typical) than an old A/C breaking right before a heatwave, but we are so glad we could help you out. Mike, Naem, and Fernando will be happy to see you had a good experience, and we will be more than happy to assist with your furnace when the time comes. Thank you for the review, Stacie! Emily FerdmanEmily Ferdman ★★★★★ I cannot say enough great things about Oasis, Mike and his team (Danny especially). They are fair, timely and extremely knowledgeable. They were patient with some building limitations and made sure I was always aware of all of my options. I look forward to working with them in the future.Response from the ownerThank you so much, Emily! Mike and Danny are amazing, and they will be so glad to know you enjoyed working with them. We look forward to working with you as well! Give us a call next year for preventative maintenance! Joe JohnsonJoe Johnson ★★★★★ I researched a bunch of companies and felt confident with Oasis Heating & Cooling after reading great reviews. Our AC compressor died and we had a brand new unit installed less than 48 hours later. Oasis exceeded expectations. They were on time, super friendly, answered all of my questions, and even educated me on how to take proper moving forward. Highly recommend them. A+Response from the ownerThank you so much, Joe! We know how important a quick turn around is in heat like this. We love to work with our clients and educate them so they can be confident in every decision they make. Thanks for the amazing review, and we hope you keep us in mind for preventative maintenance. Jake JPlexJake JPlex ★★★★★ Very efficient and pleasant technicians, thank you.Response from the ownerThank you so much, Jake! Chris BiegayChris Biegay ★★★★★ The technician for my AC inspection was very courteous and knowledgeable. The cost of the service visit was reasonable, and setting up the appointment via text was convenient.Response from the ownerThank you so much, Chris! We like to offer our clients multiple ways to schedule, and we are glad to know the texting platform worked best for you! We hope you keep us in mind in the future for your furnace inspection! Smith FeijooSmith Feijoo ★★★★★ I have used Oasis for both installs and repairs. Mike the owner and his techs are very professional, responsive and dependable. I highly recommend Oasis for all your Havac needs.Response from the ownerThank you so much Smith for the great review! If there is any other service we can provide for you or questions we can answer, please get in touch with us! Cynthia ChernoffCynthia Chernoff ★★★★★ Oasis Heating and Cooling have been so helpful to us. A couple of years ago they replaced our heater during a cold snap, and now they have saved us from the heatwave. Our AC went out Saturday afternoon, and they responded to my service request within an hour and had a tech out Sunday morning. Naem assessed the problem, recommended a new unit (ours was more than 15 years old), and installed a temporary replacement part to carry us through until the installation crew could replace the unit on Wednesday. That crew was prompt, polite, and knowledgeable. Though the installation took twice the time estimated because they had to rebuild some of the exhaust chimney, the final price was as in the estimate—no extra charges for labor time. Strongly recommend!Response from the ownerThank you for the great review Cynthia! And Naem will be glad to read it as well. We know there can be bumps in the road with an installation, but we never want to sacrifice our client's experience because of that. Thank you again, and we hope we can help maintain your equipment for years to come! Grace HynesGrace Hynes ★★★★★ Originally called because the A/C unit in my condo wasn’t working and I was looking up HVAC companies who were located in downtown Chicago and had good reviews. I made the call late Saturday afternoon and Mike the owner was able to come over on Monday morning to check everything out. He soon realized that my I needed to have my 23 year-old HVAC system completely replaced. He quoted a price for replacement (I asked around and the price Mike gave was very fair). I called back later on Monday and he was able to schedule the full HVAC system replacement on Thursday morning. I was relieved that they had availability so soon, especially for a large job. The team arrived on Thursday morning and worked quickly to get it done. There were extremely friendly and knowledgeable. By the afternoon, I finally had cold air flowing, just in time for a heat wave to hit the following week. I would absolutely call Oasis again for any HVAC issues.Response from the ownerThank you so much, Grace! We are so glad you didn't have to experience the worst of the heatwave. Mike is incredible, and will be happy to know you had such a good experience. We love to offer a quick turn around, even for jobs like yours! We hope you keep us in mind for preventative maintenance this winter!

Anthony ClaypoolAnthony Claypool ★★★★★ I've had very positive experiences with several folks at Oasis. We've also worked with 4 Seasons in the past and I have to say it's not close.
