Just prior to the heat dome starting, my air conditioner gave out. Oasis was able to send someone out the day after I called them. I could tell they were really busy. They called me the morning of to let me know they had a lot of appointments that day and they would be arriving a few hours late. They texted me when they were on the way and fixed the problem within 20 minutes. The guys they sent were polite, professional, and even found an issue with the other air conditioner that would have caused flooding if left uncorrected. I was nervous because I've been told so many things about my air conditioner needs to be replaced and it would cost thousands of dollars but Oasis said that that was unnecessary and that just the capacitor needed to be fixed. I appreciated the honesty and professionalism. read more

I contacted Oasis for a quote for a new furnace as my old one was acting up. Mike came out that same afternoon to assess the situation. We planned get the job done in the next week, but a day later the furnace totally broke. Mike was able to move up our appointment a few days, and personally came back to try to get the old furnace running before we could put in the new one. On the day of the installation, the team was prompt, clean, and kind. The job was done in a very efficient manner. Thank you, Mike and the Oasis team! read more

I was very impressed by the entire experience with Oasis and especially with our technician Naem. He was very professional and clearly very skilled with HVAC systems. He took the time to help me understand the different components he was checking and provided really valuable recommendations on service for our system. Great job and I'd highly recommend! read more

This long overdue: Replaced 2 AC's, thermostats, and did it insanely quickly. When I messed up the thermostats-they came right out. (Sat/Sun/etc) Any-they guarantee their work. Prices are fair and worth it all day long. I write mortgages for a living. Have been doing it for 25 years--and these guys blow any contractor HVAC or otherwise out of the water. read more

After maybe a year or more of our furnaces clicking and our previous service provider not be able to diagnose the cause we called Oasis and so happy we did. They came out and ordered the part we needed for both furnaces. No more clicking! We are now using them for our bi annual furnace services . read more

THE BEST!!!! After two weeks, $400 (to another company) and multiple misdiagnosis we have a brand new furnace. Did I want to spend $3,800 on a new furnace one week before Christmas? No, but I felt confident in doing so with Oasis. After calling on Sunday afternoon (someone called me back within a couple of hours) I was set up for a Wednesday afternoon appt. Oasis is so slammed because of the frigid temps that the owner Mike took my appt. He showed up on time and was professional throughout. Long story short, someone from the office delivered a part we needed. It was determine that wasn't the issue. Mike worked diligently to determine the problem. It ended up being much much bigger like a new furnace. I was told this at 4pm Wednesday night. It is now noon on Thursday and my new furnace has been expertly installed. I can't say enough good about Mike, his crew and Oasis!!! Update! New service 2020! Mike and his team have done it again!!!! I had a great experience with Oasis back in December 2014 when our furnace (in a previous home) decided to die in the middle of a record cold snap. Mike was the. Only. HVAC contractor to call me back!! Fast forward six years. Our ac ( new home) was not pulling its weight Tuesday. At 4:30 am I used the HomeMend app to request a service appt. I selected the 10 am slot. At 6:30 am Mike called and asked if he could stop by then as it was a busy day. Of course I said yes!!!!! After a thorough investigation of the issue it was determined that the 23 year old AC needed to be replaced. Mike offered the 7 am spot on Thursday. Right on time (just as they were in 2014) The Oasis crew of 4 specialists showed up before the 7 am scheduled time! Each of them were polite, knowledgeable, professional and very conscientious of the current covid 19 health concern. Our AC is pumping on this 95 degree evening! Thank you again Mike and crew for being The Best in the industry!! read more

THE ABSOLUTE BEST! In the 5 years I have lived at my residence, I have worked with Oasis and have always received highly satisfactory service consistently each time. They are lightning fast. Even during high season, they were able to get someone out at 7am in the morning the next day. And the most recent visit, Mike came out in less than an hour. I mean, where else can you get that type of service? They are highly knowledgeable, which makes you feel more confident. And they are highly effective in remedying the issue straight to the source. Their customer service is top notch. I don't think anyone can come close. Super satisfied with their services and I would recommend you don't waste your time with anyone else. read more

My water heater gas valve needed replacement. Daniel from Oasis Heating and Cooling was the mechanic that did the job. He was on time, communicative, explained what needed to be done and after the part arrived in the warehouse he came back to do an excellent job. I will use them again. Call them with confidence. They are great. read more

Excellent experience from the beginning to the end I will recommend this business Dany and his team !!!! read more

See all

Had a great experience with Oasis across all dimensions - price, service, timing, and expertise. We are in a new construction condo and have had issues with the developer's own handiwork so wanted to use an independent HVAC company to fix some issues around our smart thermostat and humidifier. The tech, Danny, did an excellent job in diagnosing and fixing our issues. He showed up on time, followed all recommended protocols for COVID, and was extremely detail oriented in examining and diagnosing what was wrong. He found a few different issues with the furnace installation and set up (beyond what we were aware of) and explained to us in detail all of the items he was fixing and the root cause of the problems we had called about. Everything was addressed within ~30 minutes and there were no additional parts required so we were only charged what was initially quoted to us for the diagnostic visit. On pricing for Oasis - we didn't go with the cheapest option we found because we wanted to make sure it was done right the first time but Oasis was definitely much more competitive than some of the quotes we received. Given how easy it was to schedule, the fair pricing combined with high quality service, and the knowledgeable tech, we will definitely use Oasis again for future HVAC needs and routine check-ups. read more

Ours was a big job. We needed a rooftop unit replaced so picture a crane moving huge units up and down past your front window. I appreciate Mike coming to double check dimensions the week before to ensure a smooth install. Hani, Danny, and team just installed everything and were great. Timely, communicative, nice to my dog. Highly recommend Oasis. read more

I cannot recommend the excellent service we received highly enough. Highly recommend this company for your HVAC needs, especially if you have a complicated issue. We have a new home and needed our AC unit, which we were unfamiliar with, serviced when it wasn't working at the start of summer. A different HVAC company came out and told us they could not help us because there was a lock on the unit. We then spoke to three additional companies who told us the same thing over the phone. Finally we hired Oasis. They had someone come out on the same day we spoke to them and were able to remove the lock and fix the issue quickly! Also the technician we worked with was very pleasant to work with! Again, I highly recommend this company! read more

I called with an AC leak on a Sunday and received a call back within the hour. Oasis was able to schedule a service call for the following morning in order to diagnose the problem and then they completed the work the following day. While its no fun to have to buy new equipment but I am grateful for how quickly they were able to resolve my issue. They were professional and courteous and really easy to work with. read more

We called Oasis for our semi annual service and they were fantastic. Responsive and quick, we scheduled a few days out and the techs were there to the minute. Did a great job and fixed a small leak as well. Highly recommend recommend! read more

Mike, the owner checked in with me and wanted to make the situation right, and I can appreciate business owners who stand behind their operations. No diagnostic/visitation fee was charged to me even though I was ready to pay it, and I appreciate that. He said he would be having a team meeting regarding proper pricing/quoting, so that might be good news as well for future customers. I may hit them up for a quote in the future, but will still continue to request quotes from multiple companies for the sake of frugality. I appreciate that this company seems to hold themselves accountable. read more

Overall great experience working with Oasis. They gave me a fair estimate to replace my old AC with a completely new system and quickly got me financed and scheduled to complete the work. The install crew arrived on-time, was very respectful of the me and the property. They finished the entire replacement of my system within 2.5 hours and everything is working great. Dealing with Oasis was a welcome, breath of fresh air after dealing with a different awful company (Four Seasons) that wasted my time, money and left me without AC for more than a week during our hottest days yet this summer. Oasis was also much more reasonably priced. Thank you to this great company and team that helped me Highly recommend! read more

Our go-to people for our AC and heater needs. We always trust Oasis will do a good job and take care of us. They recently replaced our AC and did an amazing job. I couldn't recommend them more! read more

They raced over on a Sunday, did not charge anything additional for it. Very fair price. Explained the new thermostat to me...I highly recommend them read more

I was able to schedule them within 1.5 hours on a Saturday. Tech arrived promptly with a mask on and immediately put on booties without asking. I explained to him the symptoms and showed him where the thermostat and furnace was. He was able to fix it in about half an hour (collector was full). As emptying the collector is part of preventative maintenance, he performed the rest of those tasks. He then showed and explained to me what he did and charged me the agreed on minimum. read more

I purchased a brand new AC from Oasis and the AC unit and the labor were expensive, but I understand new large capacity AC units are expensive and it was needed. My old one lasted 20 years. They replaced my AC with brand new AC unit and told me there was a 10 years parts and labor warranty- it was stated in the paperwork as well. 10 months later my Brand New AC unit was not cooling and making a loud motor humming noise. So I called Oasis and they refused to service it, they acknowledged it was only 10 months old and under their warranty. When I asked about the warranty they said it is for 10 years but they refuse to service it. Do not do business with them. Very unprofessional. read more

I want to recommend Oasis Heating & Cooling...especially their tremendously professional, timely, friendly and expert installation technicians Amir and Naem. They made an awful situation in blazing heat right with professional and credible installation of a brand new Bryant cooling system and compressor. Our air went out on the Friday night of Labor Day weekend and it was scorching. The company was out the next day to diagnose the problem and make the first available appointment to rectify the issues caused by our former HVAC guy (Dr. HVAC - do not ever use him as he is shady - lying to us that we were out of warranty and as the Oasis inspector that Saturday the worst installation of our previous unit he had ever seen). This was later confirmed by both Amir and Naem. I would definitely recommend this company as legitimate and highly professional unlike our last aforementioned Dr. HVAC (use him at your own peril - I am discussing what happened with the BBB as he refused to accept responsibility when we tried to go down that route). I do not anticipate any future issues with Oasis and our warranty and everything that they will do if we have any future issues. Again, try to get Amir and Nael if you need experienced and friendly installation technicians. They were both great in what was a nightmare situation for our family. read more

I used Oasis for a new A/C 2 years ago and have been enrolled in their energy savings program, which includes A/C and Furnace inspections every year. Today, Naem came out for my A/C inspection (I was a little late this year) and he was very courteous, right on time, and efficient. I recommend them as their prices are competitive when I compared for the A/C and their repair folks are always really friendly and take time to explain everything well. read more

Came out right away, fixed the heat and prices were really fair, love these guys!

We have consistently run into unexpected AC issues with our construction projects and Oasis is always there to help. They respond so so timely, come up with reasonable solutions, and are always extremely knowledgeable. I will never trust anyone else with my heating and cooling needs. Thank you! read more

Oasis Heating & Cooling is unbelievably great -- 5+ stars for both their customer service and expertise. We own a 4-flat which has separate AC and furnace units. Unlike other HVAC companies that upsell you and then don't deliver (avoid TDH Mechanical at all costs), Oasis truly worked to save us money at their own inconvenience. Manager Hani was awesome and showed up as promised (convenient text from company notified me he was running a few minutes late) only to suggest I should shut off the unit for 24 hours so he could more accurately diagnose the problem. He made himself completely available to work around our schedule the next day and again, he was there as promised. He completed the job recommending the lower cost fix for the repair. I highly recommend them and will definitely use them again. read more

I highly recommend Oasis. They probably are the best Heating and Air company in the city!! They did a great job installing a new Air Conditioning System! read more

I had a great experience with Oasis. Originally called out another company to service my rooftop packaged HVAC unit, and they determined that it needed to be replaced. Got quotes from 3 businesses total, and Oasis was the most competitive, responded quickly, provided multiple options, and were the most communicative. After the unit went in I contacted them again because things didn't seem to be working optimally, and they came back out immediately (twice). Things are now working great (writing this on a 90 degree and very humid, but you wouldn't know it with how nice and cool it is inside) and I'll continue to not only use Oasis for future servicing, but recommend to friends and family as well. read more

From the quote to the install, the entire process was flawless. Long overdue but bit the bullet and had a new A/C unit, furnace and a Nest Gen 3 thermostat installed. Price was fair, very happy with the work that was carried out, they also took the time to go over the thermostat functionality. Will be using for servicing in the future, highly recommended. read more

This review is for the service I received in Jan 2017. I picked the company because it had good reviews but am disappointed. Pros: easy to schedule, friendly technician Furnace was making metal grinding noise and it was not blowing out hot air. Ishmael came out to look at the furnace and diagnosed it with broken blower motor. He replaced it with an off market model. No problem. One month later, the furnace started making noise again. After several messages. I was able to get Ishmael back to take a look.He said he put a temporary solution (inserting a piece between the motor and adjacent metal piece) and that he will come back with the "rubber cushion for the screw on the heater". He never reach back despite several message and phone calls. A year later, the furnace stopped working again. Had a technician from the building look at it and was told that it is the problem of the blower motor again, the replacement model is not fitting the best and that temporary piece should not be there in the first place. read more

I cannot stress enough how much my family appreciates how professional, honest, and responsive Mike and his team are at Oasis Heating & Cooling. They are truly an exceptional team. We have had them out to our home multiple times to install a new AC unit, furnace, and whenever I have a concern about my HVAC. On several visits, Mike himself would take the service call to check my unit and answer any questions or concerns I had. As with most homeowners, we did our due diligence in researching HVAC companies and are very happy to have found and chosen Oasis. Any time I have an HVAC concern, I know they will respond quickly, and their assessment of the situation will be trustworthy. Thank you, Mike, Hani, and the rest of the team at Oasis Heating & Cooling! read more

I sent the below review to the company to let them know how I felt about the service, and I received only a response that the message would be forwarded and nothing else. Long after my message to them and this terrible experience, they cashed my check for $135 service call... LAST WEEK. I had a good experience scheduling an appointment with Hani to come out for our A/C not working. Alex came out the next day (yesterday) and said there were several pieces burnt out. He let me know we would need a new HVAC. Alex took some pictures and then went back to his truck to call his manager for a quote. He returned with a quote of $7,500 and said they could come out tomorrow (meaning today) to install. I'm not really one to make snap decisions so I asked if he could provide me a hard copy of the quote and with the details broken out for me. He said he would have the office work on it. (approximately 12:00 PM yesterday) When I called back at 3:30 to see where the quote was, he said he never did it because I didn't call. When Alex left yesterday, I was instructed to call ASAP if I was moving forward. I said I wasn't doing anything until I saw the quote details as I like to make informed decisions. During my call, Alex said he would tell the office to email me a quote. Around 5:30, Alex texted and said the office was closed for the day and I wouldn't get it until today. Now it's almost 10am and I still do not have a quote with the detail behind the $7,500. In the meantime, there have been coincidentally two neighbors whose HVACs have gone out as well. I contacted my neighbors, followed up with the companies, and have received two other quotes, BOTH with the detail behind it in an email. Most importantly, these quotes are both for $2,000 less with reputable companies. I'm not really sure why receiving more detail behind a quote is really that hard of a task, when I'm assuming you do this all the time? Given the three times I've had to request this AND the cost being significantly more, I feel like someone was trying to take advantage of me, which I do NOT appreciate. read more

I didn't start out on the best foot with Oasis in the spring of 2020 bc I was unable to get in touch anyone there for a day or two (after having had a new HVAC system installed the previous fall). But looking back, that was when Covid was just starting so I'm going to give them a pass. And I have to say... every single time I have called them since then they have responded very quickly, have remained professional, and have been wonderful to work with... especially Danny. Thank you, Oasis. read more

My AC broke down. They were able to send someone over fast. Danny who inspected the units explained everything. He recommended fixed to all 3 units we have though I only asked about 1. The crew came and replaced two units later and serviced our furnace without me asking or any additional charge. We accidentally cut the cords in the backyard, they came and found the problem, fixed it for us without any charges. Sarah in the office is on top of communication and was super friendly and helpful. Love this company. Highly recommend. read more

They came out within 30 minutes to check on my furnace, which was not working. It turns out that the air intake was likely blocked with snow, due to the 18"+ of snow last night. So, they showed me how to open up the air intake to keep it working the next few days and recommended maintenance, which I will schedule. My only complaint is that the maintenance service was not performed on the same visit (since it was the owner and he had other calls to respond to) and I have to schedule another visit. So, now I will have to pay for another service call. read more

This is the 2nd or 3rd time I have called Oasis to troubleshoot & repair a furnace issue on my rental loft. They are always responsive, honest and fair. Today I called (Sunday late afternoon) for furnace that was blowing cold air (its 22 degrees in Chicago) ... the Oasis tech quickly reached out to my tenant and was able to help fix the issue via Facetime. I'm traveling for Christmas tomorrow and my tenant is too - we are both so relieved ... thank you Oasis! read more

I've used oasis heating and cooling exclusively since I bought my condo. I had in issue with what I thought was my nest thermostat, but Demir determined it was an issue with my furnace sensor and motor. I was so relieved because my house wouldn't get above 65°! Demir explained every issue to me in terms I could understand and avoided any costly methods for the fix. His continued advice with monitoring issues in the future goes above and beyond the call of duty. In addition, they came out within hours of calling to schedule an appointment when I didn't expect them to be able to do so until the next day. Again, I'd highly recommend these services any HVAC issues you have because they're guaranteed to be solved with speediness and ease! read more

I hired Oasis Heating & Cooling to replace my old furnace, AC, and humidifier. From the start they were the most responsive and informative of all the companies that I contacted. They were able to schedule the job fast and installation was smooth. While installing my smart thermostat, there was an unexpected wiring issue but they solved it in no time flat with creative thinking. From the receptionist, to the sales person, to the crew, and the owner, they make you feel comfortable that you hired the most knowledgeable and professional company. I highly recommend them for your job! read more

I have used Oasis several times now and cannot recommend them more highly! When I lived in my condo they replaced the rooftop air unit, , came out quickly for a follow up issue the following year (my fault, not the unit!) and could not have been nicer. I recently moved and came home from the 4th holiday to find my house without air - Oasis was out at 7 the next morning. Naem could not have been an ounce nicer or more professional. Pricing is very reasonable. These are the people you want to work with! read more

Just had a totally great service call with Danny. Instead of simply checking the furnace he asked me if everything was ok and listened. He helped me fix an issue that was going on for 5 years. It just took a little investigation and a simple but very smart adjustment. He was on time, wearing a mask, and a total pleasure. That is two successful visits (the other one was last service check 2 years ago) from Oasis. They will be the only one I call if I need something. read more

Well known beginning of the story, my A/C stopped working around midnight couple of days ago when outside temperature was still around 80F. After calling several HVAC companies just to get voicemail and opportunity to leave a message I realized that my family will have to ride it through the very hot and uncomfortable night. Unable to sleep I called Oasis around 6AM next day and get Mildred on the phone who took my information and told me that she will forward my info to available technician. It didn't sound promising, however after 15-20 minutes I received phone call from Hani (I believe spelling of his name is correct) who informed me that he's on his way to my home. Upon his arrival and proper introduction he quickly assessed situation and replace bad capacitor and my A/C was back being operational. Great service, knowledgeable and respectful technician and most importantly fair charges for a repair. No wonder that Oasis has such a stellar reputation on Yelp. Keep up with a great job! read more
