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!

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.

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.

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

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.

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!

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!!!

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.

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.

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.

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.

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.

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!

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!

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.

very good servicevery professional and effecient

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!

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.

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!

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.

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!

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

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

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.

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.

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!

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!

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

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!

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!

These guys are the best. They went above and beyond to solve the problem. Very honest and knowledgeable. Quick response. Trust them fully

Naem was punctual, communicated each step, and got our AC fixed quickly on a hot day! He also provided helpful tips to make sure our units keep working well going forward!

Always responsive and thorough!

Oasis installed a Bryant furnace / ac combo in my duplex apartment. The guys did a good job with a challenging downflow furnace and horizontal coil installation. HVAC work is expensive, but Mike’s price was the most competitive.

We inherited some old systems in our newly purchased house. Oasis installed our new furnace last fall and we have been really happy with it. Our A/C unit just died and we had Oasis out to diagnose. Naem was a fabulous technician and helped us understand what was going on and answered all of our questions. We appreciate their quick and efficient service.They were able to schedule us for a new install (the very next day!) and it was completed within 3 1/2 hours. We are very pleased.

Team and Techs are super helpful, fully explain their process the entire way. What the issue is and what could cause it.

Called Oasis Tuesday night at 9:30pm after my central AC quit on me. A tech was at my apartment at 8:30 Wednesday morning and had me up and running by 10am. 5⭐️’s all around

I was incredibly impressed with my first interaction with Oasis Heating and Cooling. On a Sunday morning, we woke up to a broken air conditioner. That particular day was over 90 degrees and extremely humid, and we were hosting a birthday party for my 1-year-old son. With a large number of guests arriving in the next two hours, the AC breakdown couldn't have happened at a worse time.I called various heating and cooling companies across the city, but none were available on a Sunday, and the next available appointments were not until the following week. I knew it was a long shot to get someone to our home on short notice on a Sunday morning.However, this is where Oasis Heating and Cooling truly stood out with their exceptional service and customer care. I left a message with their team, and they showed a tremendous amount of care and concern for our situation. I received a call back almost immediately from a technician who said he was on his way and would arrive within 15 minutes.The technician was extremely thorough and efficient while being mindful that we were preparing for my son's birthday party. I want to thank the entire Oasis team for helping our family in a difficult situation. I truly appreciate your work and for going above and beyond.

Expert work and prompt service. Thanks again!

Oasis was prompt came within the window of time, a one hour window as well, which was appreciated, showed me what they were doing, and were in and out very quickly. Thanks!

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.

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 again

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!
