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 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

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

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

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

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

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

Oasis did a fantastic job replacing our old Air Conditioning system ... all of their employees were Professional, Friendly and very hard working. Also, They were extremely efficient. Highly recommend this company! read more

First off I'd like to say my post was real. I am a real customer of Oasis. My first post was now removed. If after calling in speaking to medina and ownership not returning my call about there employee armin. When he was at our location armin asked to use our restroom in our house. He spent at least 20-30 minutes as well. Like I said before my husband is in recovery. My husband posted under Pete so now we're using my account to highlight a issue. And we don't want to come forward any longer we tried to mike. So I'm not fake at all as you reported & have you drug tested this employee? Why not post that as well in your reply as well. I'm a very real customer as armin as a real O.B issue as well. We're 100% positive your employee was doing some sort of hard drugs in our bathroom. Pretty sure crushed pills or cocaine as there was some left on out bathroom sink with alot sneezing snorting issues out of armin. read more

I'm posting this due to non returned call by the Madina(as I spoke to her directly) & my issue to which I was not called(in july back about involving there service tech a named Armin. I've had a couple service calls to which Armin has been the tech in question. My wife picked up on it the first time he was at out residence doing repair work on our new Ac unit from last summer. Its still under coverage but the issues are endless. Anyways his first visit he asked to use the bathroom and my wife didn't think anything about it. While in there after a couple minutes. She noticed a weird white(not very much)power like on the bathroom sink. She also heard a few sneezes and the slight sound of snorting as well it seemed to be. The second time he was out at our location I was home. I'm in recovery for drugs mainly pills & coke abuse. As a user in recovery(14 months) I fully am aware of the signs of these behaviors. He did again ask to use our restroom on this visit and again we heard the sounds of slight sneezing and snorting sounds. I am let down overall that its come to this writing a yelp instead of a returned call by ownership to which I was told would happen. read more

We just had another excellent service call with Danny from Oasis Heating & Cooling. They were able to come out the same day when our a/c went out. Danny quickly assessed the issue, ordered the parts and was able to come back out within 24 hours. I really appreciated the follow-up from both the office and Danny. I continue to recommend Oasis to my friends and clients. They are very professional and easy to work with! read more

OHC was highly recommended to us for an AC install. I called Mike to schedule an appointment and provide a quote. He swiftly came by the next day at 8 am. He was kind, professional, and explained what needed to be done. It was not an easy task considering we live in a townhome and had to get the AC unit 30ft onto the roof. He explained everything in detail, answered my questions, and provided a reasonable quote. He scheduled for the install to be done this week. However, when I told him I had a 1yo baby that has trouble sleeping at night from the heat. He scheduled the install for the very NEXT DAY. His team arrived promptly at 7:15 am and got to work. Despite it being a 95 degree kind of day. Everyone was friendly and were total troopers for the next 4h to get the job done. Also, I'd like to add that our pipe from the furnace was sitting on the drain. Dameer offered to make the pipe a 90-degree angle so it could fit directly into the drain. He wanted to make sure the drainage would not leak all over the floor. They were done with the AC install but he offered to do this extra step. I mean this is what you call service. I also left a big jug of ice water for them inside our doorway because it is sweltering hot outside. Please remember they too need to stay well hydrated on days like this especially when on the roof. Anyway, we are extremely pleased with OHC. They have the most reviews on Yelp (for heating and cooling services) and I can attest to their high level of service and professionalism. Mike, THANK YOU! WE APPRECIATE YOU AND YOUR TEAM. p.s. My little one will be happy tonight in her crib today and the rest of the summer because of OHC. read more

I can not say enough good things about my experience with Oasis. Danny came out on Friday to confirm that our 20 year old furnace had officially died. He was honest with his diagnosis and at no point came off "salesy". We could have shopped for a few more quotes, however we felt that we had developed a trust from our couple interactions with Oasis & their staff. Fast forward to the install: Fernando & Asim showed up for the install on time, they were professional & efficient,and respectful of our condo associations rules and regulations. Please do not hesitate with hiring Oasis, the pricing for the install and furnace is more than competitive. Thank you Oasis for getting us through this challenging time. read more

Oasis H&C came out this week to evaluate my upstairs HVAC system. While checking the pressures of the coolant, Danny, was able to answer some of my other questions regarding my HVAC setup. I asked him about needing to run another wire from thermostat to the furnace/fan and was informed of a device that would effectively "add a wire" without the painful task of actually adding a wire. Now I'm able to keep the fan on all the time to circulate air to keep the upstairs cooler. I appreciate that he went above and beyond what the service call was for and assessed that I could handle this small wiring job on my own with a little instruction. read more

Great experience all around! After issues with our previous HVAC company following up for service, we called Oasis during the hottest week of the year because our air was failing. We got a call back within an hour or two, and Mike was at our house a couple hours after that to diagnose the problem. They were even able to offer an installation appointment the next day, and did a great job setting up a new system. Great communication, great follow-up, and very professional at every step of the way! read more

This post is way overdue. In Feb 2019, the polar freeze caused 5 pipes to burst in my house. Needless to say, I had several feet of water in my basement which damaged my existing water heater, furnace, & dehumidifier. I called OHC over the weekend & Mike said Damir was 10 mins away so he came over for an initial inspection. After the 3 ft. of still water was drained, Damir, Vaha, Anel, & Bobby came back with new equipment and installed everything within a few hours. Everyone was professional & courteous, but Damir & Vaha were absolutely the best! I believe these guys all went out of their way to help me during my very difficult time. They were extremely knowledgable, professional, & trained the junior staff on how to install the equipment correctly. The junior staff members were also their sons. OHC carefully selects their employees by family referral because they want reliable and respectful people entering your home. Bobby went out of his way to purchase an extra part for my furnace and Vaha gave additional advice that there was another burst pipe which was not identified before the main valve was turned on again. I highly recommend OHC for your HVAC needs. read more

Couldn't recommend this company more! After getting quotes from multiple companies, Oasis came in at about 1/2 price. Then, I had to reschedule multiple times due to dependencies on work from other vendors, and they were amazingly accommodating. After the second reschedule, I was originally told that they wouldn't be able to come out for about 4 days (which seemed totally reasonable to me), but then I received a call back from the owner 15 mins later (who was out of town, on vacation) stating that he'd get a crew out there next day, being that it was supposed to warm up over the next few days (which, I hadn't mentioned). AMAZING experience. read more

I cannot recommend Oasis enough. Our furnace stopped working over night and I called Oasis from the Yelp reviews. The reviews are not lying! The service was amazing. They came the same day. Hani was assigned to us and they were able to diagnosis the problem in no time! Hani did not have the part on hand but was able to get our furnace working for the day and returned the next to clean our unit and replace the capacitor. Hani went above and beyond with customer service and professionalism. When we asked about the cost of replacing our entire HVAC system, Hani was able to give us a rough estimate. On top of this he told us "Shop around!". This is true professionalism when they encourage you to do your own research. When our HVAC system needs to be entirely replaced I WILL be going with Oasis and with Hani. It felt amazing to know you were in good hands. PS: Hani encouraged asking questions and answered every question we had. Let's goo! read more

We needed our ancient thermostat replaced with a digital new one. Since it had different wiring, no one knew how to install it. So we new to call oasis, and of course they fixed it for us! Damir was very knowledgeable and extremely respectful to our home. Would recommend! read more

Went to the website, and got a call back. That's the one star. They told me they'd send a quote. They didn't. I called back, but this time I didn't get a call back. I send an email. No response, no quotes, nothing. read more

Had issues with my furnace getting warm. Made an online appt. Wednesday, they confirmed they could be here on Thursday morning. Pavi came out and talked about replacement parts. We discussed the furnace was 15 yrs old and decided it would probably be best to get a new furnace. The recommendation including the labor was much better than I expected. They were able to get me in on Friday, right in time for the cold nights over the weekend. They were professional and cleaned up afterward. They took time to explain what I needed to know about the new thermostat and humidifier I also had installed. Overall, I was very impressed with their responsiveness, the service, and their technicians. I would recommend them for anyone needed heating or cooling needs. read more

I have used Oasis Heating and Cooling for 20 years, and have their annual service agreement. When my air conditioner went out on the hottest day this summer, and I was entertaining, I had someone come out within 2 hours to get my air conditioner working. I was planning on replacing it anyway, so he did not charge for the repair, and gave me a good price on a new air conditioner and furnace. I have always gotten very good service, with friendly, repair men, who are always very cautious to cover their feet, and face (during Covid). judith read more

We have used Oasis for the last ~6 years. Anytime we have an issue, they are immediately responsive. They are dependable, communicative, and fast! They've always been priced reasonably. Most recently, we had an issue with our AC in the middle of the summer. Oasis was able to come out the day we called them. Naem and Fernando were terrific - they were able to figure out the issue quickly, recommend a solution, and execute the solution in record time. Both of them were a pleasure to work with! read more

A few years back we experienced some issues with our AC unit. I contacted Oasis based on their Yelp reviews. The technician came out the same day and reported that our unit was leaking refrigerant and would eventually need to be replaced. Fast forward three years and we once again experienced an issue with the unit's ability to keep up with the early season heat. This time it was the owner, Mike, that came out (same day and completely fit us in while extending his day) to address the issue. He filled out unit with the coolant and then put us on the schedule for a new air conditioner a few weeks out. He gave me a great deal and was very fair in pricing and approach. I would highly recommend Mike and his team to anyone looking for help with their HVAC needs. Also, Mike has a great app called Homemend. I used it to talk to him that morning and it enabled me to schedule him instantly for the same day and know that we would the issue resolved before the end of the day. This app works for a variety of services and allows you to find a technician closest to your location and then chat with them and ask them technical questions in real time, and hire them instantly. It works from both the provider's website or your mobile phone. Just search for Homemend on Google Play or the App store. So much more convenient than calling and waiting hours for a return call! read more

Oasis Heating and Cooling is an outstanding company! They have an operator who will answer your calls during the evening. I called Friday night at 9:30pm. My A/C was leaking. The technician, Hanie, ( I apologize if the spelling is incorrect) called me back quickly and came to fix the A/C the next morning! I'm definitely recommending Oasis to family and friends! read more

This is a highly trusted business. I've worked with them for the past 10 years and they are absolutely,hands down one of the best customer focused businesses I've come across. I had an issue with my A/C recently (during one of those 90+ degree nights) and called to leave a message for the morning.......the owner of the business Mike Causevich answered my call and walked me thru what to do to fix my system without them having to come out. I give them my highest recommendation. read more

Thank you, Naem, for an efficient fall service visit today! I'm so glad I signed up for the maintenance package and feel confident both spring/fall service visits will keep all systems running smoothly. I learned new things (thanks for being patient with my questions) and your informative, friendly presence was delightful. Excellent service. Prompt (the earlier timeframe worked out great!). Respectful. Highly recommend. read more

Great service. Furnace was making a squealing sound. Bobby took a look at and serviced it quickly. He was professional, courteous and explained what he was doing. Would use again. read more

I've used Oasis last year for an HVAC system replacement and had a great experience so when I moved into a new-to-me condo with an aging AC and furnace I called them again. Pricing was good and they were not intimated by getting a crane to get the AC unit on the roof. Great communicators throughout the process for both installs and no mansplaining! Crews were friendly, tidy, and worked efficiently. read more

I needed to replace my furnace and narrowed my research down to Oasis and another high review company. Needless to say I chose Oasis and I couldn't be more happy. I called on a Tuesday to schedule an appt. and on Wednesday Danny came out and gave me an honest estimate with no sales pitch or upsell. I appreciated his direct and informative assessment of my options so I excepted the offer. The next morning Vaha, Asim, and Armin showed up on time, and ready to install my new furnace. My experience with Oasis was easy and seamless. If you're in need of any heating or cooling services, I highly recommend giving your business to Oasis Heating & Cooling. You won't be disappointed. read more

I don't usually leave Yelp reviews but Oasis was excellent. Showed up within 2.5 hours of calling even though I noted it wasn't an emergency and could wait until the next day (and I called after 5PM on the coldest day of the year). Bobby was fantastic. He walked through everything with me, answered all my questions, and diagnosed the problem really fast. I am always nervous about blind calling service providers but this was honestly a great all around experience. read more

This place is amazing. I emailed company through yelp after 5 pm yesterday and received a response within 10 minutes. We scheduled an appointment for today and we couldn't be happier with the service and price. This company deserves its high rating. read more

I've used the services of Oasis twice in the last 6 months. The first time, our HVAC blower was broken and they replaced it and the 2nd time, the furnace needed some basic servicing. Booking the appointment both the times was a breeze and we were able to find open appointments fairly quickly. Both the technicians were on time, extremely courteous and did a great job walking me through the repair step by step. They were also very patient answering my questions and gave me a good list of best practices on my HVAC unit maintenance. I highly recommend them and would not think twice before calling them for future needs read more

Over the weekend, our thermostat lost power and after several DIY attempts, we decided to reach out to Oasis. We called on Sunday afternoon and they were able to schedule an appointment at 7 am the following morning. They were prompt and efficient. He took the time to explain what he was doing and as he diagnosed our issue. Within an hour, our furnace was up and running. We will definitely be using them again! read more

Standard maintenance and servicing costs $135, but it's not worth it. I can only speak to the standard maintenance/servicing that Oasis offers. As others have stated, their flat non-negotiable fee for a visit and general maintenance is $135. Save your money. If you don't have a specific issue and only want general maintenance/service, you are better off doing it yourself. The extent of the maintenance/service is as follows: 1) replace humidifier filter ($15); 2) replace air filter ($15); 3) very poorly wipe up dust on a couple parts with what looked like dry paper towel; 4) 10 seconds of scrubbing some parts with what looked like steel wool. The whole process was finished in 15 minutes. I acknowledge that, if there was a serious issue, Oasis could have diagnosed it. But, I knew there wasn't going in. I'm giving them three stars because: 1) they are professional; 2) prompt; and 3) the service technician was happy to educated me about the parts and asked if I had any questions. Again, if you want only general maintenance/servicing, and you do not believe anything is wrong with your system, save your money. read more

Called for emergency service on a Saturday afternoon. The woman on the phone took my information and assured me someone would call back right away. No call back. 3 hours later, called again. Gave my info again. The woman on the phone took my information and assured me someone would call back right away. No call back. 2 hours later, called again. Gave my info again. The woman on the phone took my information and assured me someone would call back right away. No call back. 4 hours later, called again. Gave my info again. The woman on the phone took my information and assured me someone would call back right away. No call back. Literally tried 4 times. The woman on the phone was completely unhelpful of course and only knew how to take down the info. Wasted an entire day. read more
