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.

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.

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.

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.

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.

I have used Oasis several times and have had exceptionally great service each time. The techs are kind, thorough, and knowledgeable. They even take their shoes off at the door, which is so considerate! Oasis’s prices are fair. I’ll definitely continue to use them for maintenance and eventual replacement of my unit.

Sarah Templin

Oasis Heating did a wonderful job coming out to check our heater. They arrived within a few hours of my initial call and the technician, Fernando, was efficient, professional and friendly. Problem was solved with a relatively easy fix and the entire process was SO much better than I anticipated. Highly recommend.

Kristi Seibert

I recently bought a condo and needed to get my furnace serviced for the winter. The first company I hired came out but told me they couldn’t service my furnace after seeing it was located in the ceiling. I called Oasis and their technician had no problem accessing and servicing my furnace. Later when I needed to change the filter in the furnace, it was hard for me to access and change. I called Oasis at 7 pm one night for help to get it changed. The technician Hani stopped by to change the filter for me the very next morning and Oasis didn’t even charge me! I’ve also hired a plumber through Oasis to fix an issue with my toilet. He was very helpful and I’ve had no issues since. I plan on using Oasis for all my HVAC needs.

Response from the owner: We are pleased that we have e another happy customer.Thank you for your feedback and your business.

Purvs D

We’ve been using Oasis for our annual maintenance for many years and have always had a great experience. Naem usually services our hvac and ac and is punctual, polite and very thorough. Their scheduling and billing system is perfect as well.Update: Just had them install a new furnace and was once again very pleased with the experience. Naem explained why we needed a new furnace and Fernando and Michael did a great job with the install. They were professional, polite and the job was done in a timely manner. After install, they registered our new furnace and sent us post-install documents. We feel like we are in good hands with Oasis.

Response from the owner: We appreciate your feedback and support.Thank you and we look forward serving you again in the future.

AthleticAF - Jeremy Aniciete

Oasis heating and cooling, Anel & Vaha were very thorough, efficient, and made sure everything was working correctly. They explained on what they did and provided great information about our new furnace.

Response from the owner: Thank you for such a nice review and feedback.

Melissa Lev

Response from the owner: Melisa,Thank you for your review.

Fabulous work by Chris at Oasis. He came out to descale, clean and inspect my 11 year old tankless water heater. He was friendly, knowledgeable and answered all my questions to help educate me on all the parts and functions of the heater. Thanks Oasis, Thanks Chris!

Response from the owner: Thank you so much for your review and your business.It was pleasure working for you.

Louis V Haynes

The owner went above and beyond and came by on New Years Day and got our furnace installed the very next day for several thousand less than their competitors; I could not recommend them enough.

Response from the owner: We are happy to serve you.Thank you for your support.

Mike Clark

I’ve finally found an HVAC company I can count on! Mike and his team at Oasis have come through for me several times on short notice. I highly recommend working with them!

Response from the owner: Mike ,Thank you for your review and we look forward to help you in the future.

Loaves & Witches LLC

I am so beyond impressed with Oasis. Being a new business owner with TWO busted HVACs, it’s so stressful to find a trustworthy company to turn to. I am so grateful we went with Oasis. Daniel was incredible. He took videos and pictures to show me the issues with the machines. Daniel was in communication at every step in the process. Now sitting in our toasty cafe with Daniel and Oasis to thank!

Response from the owner: Thank you for your review and we look forward serving you in the future.

Matt Gottesman

Had a great experience getting a humidifier replaced. Naeem, Jacob and Chris were all super helpful, answered all my questions, and went the extra mile with the installation. Would definitely recommend!

Response from the owner: Thank you Matt.We love your feedback.

Erika Baroman

10/25/2024 edit: Two gripes I'm adding on here. I wish you can schedule online without having to wait for a reply or an email back and forth. I believe they had it at one point and then it went away.And two, I had a thermostat installation on Tuesday morning by Hani. Great service, super professional. But I didn't get a receipt emailed to me until I asked for it on Friday afternoon (because I needed it for rebate for Comed & People's Gas). And I was made to feel like I was a bother when I followed up my email with a phone call. Well, I wouldn't be emailing and calling if I got the receipt at least within the same day my credit card got charged. When I had my HVAC serviced about a month or two ago, I got the receipt within a minute of me paying. Not sure what was different this time.I’ve used Oasis for a couple of years now. They are wonderfully on time and easy to schedule with. Always very professional and makes sure to let me know about everything they see. I’ll keep on using them for the foreseeable future.

Response from the owner: Erika,Thank you for detailed explanation.We have a new system at we are still llearning.As usually ,we always look for improvements.

Kerry John

I arrived home on a Friday evening to find a furnace gas leak in my downstair's tenant apartment. People's Gas quickly turned off the gas, and Oasis came the next morning to investigate the problem. Given the age of the furnace I was not surprised that it needed replacement. They were able to start and finish the new installation on Monday afternoon. I really appreciated that my tenant did not have long to wait before heat was restored.

Response from the owner: Kerry,Thank you so much for your review.We appreciate your business.

DENIO DIFRANCESCO

I have been using them for around 25 years and they always due a good job and at reasonable prices. They have installed all of the ACs and furnaces at our three flat

Response from the owner: Hi Denio! Thanks for sharing your Oasis experience. It means so much when our best customers share their experiences. We're really pleased to hear that you are satisfied with our services and look forward to keeping you a happy customer.Sincerely,Your Oasis Team

Rachel Garko

Jason was extremely helpful. He not only fixed our AC unit but clearly and patiently explained what was wrong. He was professional, hard working and solved all our issues! Highly recommend Oasis especially Jason.

Response from the owner: Thank you so much for your support.

Brian Robinson

We suddenly discovered we needed to replace our HVAC system, and Oasis was able to fit us in on short notice and at a reasonable price. They also did it during a trip that we couldn’t cancel, so they were flexible with us not being there. Great service!

Response from the owner: Thank you.Looking forward to serving you in the future.

Martfam

I highly recommend Oasis Heating & Air Conditioning. Everything about their process was expert level service. We had to have our entire unit replaced. The service guys Anel and Vaha did an awesome job in moving the new unit to a proper location in our backyard and installing quickly on a very hot day. Oasis gave a much better quote then other companies. I will use them for everything AC and furnace. Thank you Oasis!!!

Response from the owner: Thank you Martfam.We are pleased with another happy customer.

Dimitri Venice

Thank you to Mike who sent me his three angels today on the hottest day of the year. Thank you Anel , Vaha, and Kiki. They showed up on time. These boys were very professional, polite, kind, and oh my god clean. They did such a good job. I called during the middle of a heatwave when my A/C died. Mike quoted me on Monday and Installed on Tuesday. Very affordable and have very competitive pricing. I got three other quotes, that were just outrageous compared to Oasis. The pricing was very fair, especially for this economy. When the furnace finally dies I know where I’m getting my new one. Thank you for squeezing us in, and thank you for the fantastic customer service.

Response from the owner: Thank you for your review.Three angels are very happy and appreciate your kindness.

Allen Dozier

Today was a very hot and busy day and Mike D (Mike Squared if he reads this) was prompt, courteous, and ran me through all I needed to know about regular maintenance. Do yourself a favor and call Oasis as everyone I interacted with was friendly and prompt and the price for service was more than reasonable.

Response from the owner: Thank you so much for such a review.

Danielle Hasdal

I can’t say enough GREAT things about this company and their service. They sent someone same day to service our broken air conditioning unit. We are supposed to have 90+ degree weather this weekend so we really appreciated how quickly they came. Naem was SO nice, very knowledgeable, and gave us great tips to help extend the life of our unit and keep our place cool on very hot days. So happy with the service and highly recommend Oasis Heating and Cooling.

Response from the owner: We appreciate your feedback so much.Thank you .

Robert Johnson

When my furnace started failing this past winter I contacted multiple HVAC contractors. Oasis was the only contract who didn't try to sell me on an immediate replacement. They cleaned the unit which got it working well enough to last another winter. They also provided a no-frills quote that the least expensive of their competitors. It felt like their priority was working with me to find the optimal solution to fit my budget.Fast-forward to this week. Oasis replaced my entire HVAC. Fernando, Mike D and Amir worked quickly and professionally. i was surprised by how smoothly everything went. I couldn't be happier.

myles walters

Oasis Heating and Cooling was responsive, quick, and extremely professional. Mike is the one to ask for when you call, he runs the team of techs there and really knows his stuff. Air flow in my home has been an issue for a while now. Oasis showed up, diagnosed the problem and got it fixed all in one day. Home A/C is way more consistent throughout now. Will definitely use Oasis for all my home Heating and Cooling needs.

Elisa Nolte

Oasis Heating and Cooling really helped us out when the very old air conditioner that came with our condo died during a heat wave. We needed a crane to get the new AC unit on our roof and, despite that, Oasis was able to schedule us to install the new AC on Monday when we called for help on Friday morning.The team who did the install was also fantastic: Fernando, Michael, and Amir. They were quick, efficient, and professional, and had our new AC up and running in no time.I would definitely use Oasis again!

Amber Dow

My AC was not working when I woke up in my home this past Saturday. I called Oasis and Damir called me soon after saying he was 20 minutes out. He arrived and took a look, and was able to diagnose the issue right away with a new capacitor. The diagnosis and work in total took about 30 minutes. Since the unit was under warranty I only had to pay for service. Damir was incredibly efficient, professional and knowledgeable as he educated me about what was going on and how he was going to fix it. The service was prompt, thorough and incredible! He had my AC back to working in no time at all!

eddye harris

Oasis accommodated a last minute request of service to my business Raise Your Glasses optical on 1345 s Michigan Ave. they were punctuall, professional, and precise. They are my choice for business and home heating and cooling.

Response from the owner: Thank you so much for the review, Shoshana! We have always enjoyed working with you and look forward to working with you for years to come!

Hillary Kribben

Oasis to the rescue! After my air conditioning unit went out last night, Oasis was at my door by 10 AM this morning. I was lucky enough to have had the owner of the company service my unit with unwavering professionalism, thoughtfulness, and extreme knowledge (he even took the time to explain the intricacies of the unit itself to me). I’ve been raving about this company tomy friends and family ever since he left this morning! I highly recommend this company over all of the others in the Chicagoland area. Thank you again, Oasis!

Response from the owner: I'm so glad we could help you, Hillary, and Harvi will be glad to know it too. Our customer service team is also thrilled to know you were more than satisfied with our service. Thank you so much for your review and we look forward to working with you again!

Darcy Dodd

I’ve had Oasis service my unit multiple times, and they are always communicative, prompt, and professional. They seem to take care to not overcharge and not recommend unnecessary repairs, upgrades, etc. Highly recommend.

Pinar Aral

We are very happy with Oasis services. This is our third time using them. The other times were a great experience. Recently, we needed them again as our AC was having issues. The technician Harvi was friendly, on time and knowledgable about AC unit. He identified and fixed the problem quickly. We will use them again. Thank you!

Asim M

The service was excellent, the staff was friendly, and the technicians were knowledgeable. Oasis provided the most competitive quote. Our unit is back to normal operation after a new compressor was installed.

Drew B

I had an awesome experience with Oasis. We had a leak in our HVAC system and they showed up right away to fix it. Naem was great and was able to fix the system in no time. Would recommend them to others!

Jason Caref

Mike and the technicians are always great - we have been using Oasis for 20+ years and this a great service - highly recommend!!

Response from the owner: Jason, we're glad to know we can consistently provide you with amazing service. Thank you so much!

laura rupp

Mike came so fast on a Sunday night! He was very professional and transparent. Would recommend!!

Isaac Reinemann

Oasis was incredibly helpful in diagnosing my AC issues. The tech was knowledgeable and willing to explain the problem and come to a reasonable solution.

Cynthia Cho

I cannnot recommend Oasis Heating & Cooling more! We have used them twice so far. Once for installing 2 HVACs in our city townhouse, requiring a crane and removal of old units. The process was smooth all the way through. Hani and his team were professional and communicated well from estimate to completion. Following that experience, we continued with maintenance of our HVACs with Oasis over several years.This month, we just purchased a home in Chicago. The previous homeowner had at least 1 dog and left visible dog hair throughout the home. After cleaning the house, I looked in the vents and found more dog hair. We decided to call Oasis for a Vent Cleaning estimate, a relatively new service they provide. Although their schedule was full with A/C jobs, they fit us in because we hadn't yet moved in, so access to the vents was easier. Vaha, Kike, Fernando and their team were amazing, particularly on a warm and humid day, which you can't run AC while the cleaning is in process. They went above and beyond fixing and replacing vent covers that were reversed throughout the house. Again, they communicated through the entire process and took care of everything that came up during the service.We did get estimates from other vent cleaners who offer initially low looking rates, but then charge per vent that they clean or have other ways of making the price difference up. I also found some of them to be uncaring and/or pushy about their service - very "take it or leave it" attitudes. Oasis is reasonable with a per HVAC charge that includes all vents that are connected to that HVAC. Their equipment is top notch and their staff - from estimate to completion are caring and professional.I would not hesitate to use them again and strongly recommend their services! This is a fantastic company!

steve abrams

I have used OASIS for the past 15 years EXCLUSIVELY- they are the best...the staff is unsurpassed, their pricing is excellent and they are fair and honest beyond comparison. Today, they replaced my entire HVAC system (furnace, compressor, etc.) in under 4 hours and their work is exemplary! Thank you, OASIS, as always!

Response from the owner: Thank you so much, Steve! Year after year, we are happy to work with you. We love our repeat clients, and look forward to maintaining this new system for years to come. We were happy to work with you, as always! 😀

Barry Janovsky

Great company. All the technicians take the time to explain everything. They are timely, professional and knowledgeable. Great Work.

Response from the owner: Thank you so much, Barry! We are more than happy to explain every step, and glad to assist you.

Les Carter

Scheduled quickly when we had a leak in our upstairs AC unit. Came right on time next day. Solved the issue. Friendly service with clear explanation of what was needed. Thank you!

Response from the owner: Thank you for the great review, Les! We are more than happy to help explain the solution, and look forward to helping with preventative maintenance in the future.

Raelyn Cooper

Absolutely amazing service. I called at 9:30pm and someone returned my call within 10 minutes with an appt that worked with my schedule. Discussed issues, how to avoid in the future and does/don'ts of using AC in hot months. We have used them for 5 years now! Highly recommend!

Response from the owner: Thank you so much, Raelyn! We do our best to always offer top of the line service, and love to help maintain our client's equipment year after year. Thank you for the recommendation, and we look forward to assisting you again next year!
