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.

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.

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 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.

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 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.

My boiler kept overfilling. Found Oasis on Google. Text them at 6am. About 7:15 Danny was here. Found the problem and explained what had to be done. Oasis was very good about letting me know what was going on after the first visit. Danny came back the next day. Did the work in about 3 hours. Explained again what was done. I am pleased. I Would contact them again if needed.

Hillary W

We had a great experience and would highly recommend. Our furnace stopped working around 8PM in the middle of a Chicago winter. We called at least three different places before Oasis and the companies had said they couldn’t send someone out and left it at that. I spoke with someone from Oasis and he was friendly and assured me that our pipes would be fine through the night and would send someone out first thing in the morning and got us scheduled right away.Someone came in the morning and suggested that we replace our 23 yr old furnace since the replacement part would be 1/5 of the cost. We were able to get someone out a few hours later to replace our furnace and humidifier at a competitive rate. I really appreciate the ease of appt scheduling and their professional staff especially during a time where we were panicking a bit!

Response from the owner: Thank you so much for your positive feedback, Hillary! Our team is committed to delivering quality service, and your feedback is a great encouragement to us. We look forward to working with you again soon!

Oasis couldn’t have been better! Our boiler was leaking. I talked to a real (and friendly) person to book the appointments to inspect, order the correct new one and then replace.

I have used Oasis several times and have had exceptionally great service each time. The techs are kind, thorough, and knowledgeable.

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.

Lauren Furlan

Response from the owner: Thank you for 5 stars.

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.
