Customer Reviews

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 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 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 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.

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 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.

Mike owner of the company is awesome
Fast turnaround in extreme 100 degrees heat my in-laws AC unit went down, called Mike. He had it done the next day. His price was phenomenal as well

Marissa McMahon

Very efficient and polite. Explained everything in a kind manner. Would definitely go to them again.

Immanuel Choe (Manny)

They were quick to arrive and I had my AC capacitor replaced within a couple of hours after it failed. Only the cost of the service which was $440 was on the higher end in my opinion but I would definitely seek their services again.

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.

Richard Duslak

Service was excellent. Technician was on time very knowledgeable, and explained thoroughly what he was doing and what needed to be done.

Andrew Clancey

Much more affordable and way better service than their competitors. I'm looking forward to continuing to work with them.

Harold Shinnick

Response from the owner:Hi Harold! Thank you so much for the positive review! We're here for all your heating, cooling, and plumbing needs and look forward to working with you in the future!

Benjamin Rivard

I called Oasis to come out as one of the AC units on the roof of our house makes very loud rumbling vibrations when it runs. I am so glad that I called Oasis; from the moment he arrived the technician, Hani, was incredibly professional and knowledgeable, and was able to figure out that the builder had installed the unit in such a way that the vibrations transfer into the roof structure, and that the unit itself was working normally. Hani was very up front about options we have to remedy this issue, and suggested that we start with changing out the plastic pad it is on and installing vibration isolating rubber padding for the unit to sit on. He did discuss several other "fixes" that we could consider if the padding doesn't work, but was confident it would help. Hopefully we can get the service scheduled soon and get it taken care of, so I can't rate/speak to the end-result yet, but my experience with Oasis so far has been phenomenal.

Oasis management team- Hani deserves recognition for representing your company extremely well. His attitude and professionalism made me want to continue working with your company going forward. If we get the vibration issues sorted out, I see no reason why I would ever call another HVAC company for our maintenance and emergency needs.

Romy Connor

I used Oasis for both a/c maintenance and a water heater flushing. Guys were on time and very professional! Fair quote on both services..and didn't try to upsell me on things others had tried to do-luckily I have a friend that's a plumber and said what was needed. Will definitely be calling Oasis for future plumbing needs!
Appreciate the honesty. One other company gave me a ridiculous quote..for something I didn't need-won't mention any names-but all reviews mentioned how high their pricing was-do some research!

Ann Wilson

Naem was fantastic. He was friendly, on time, and communicative about our furnace. The service fee was very reasonable, and I never felt as though he was trying to upsell me on any Oasis programs.

Response from the owner:Naem will love to read the kind words you left about his service! Thank you for the feedback and we hope you visit us again!

Chris Knoff

Fast, high quality, helpful, professional.

Patrick Hoffmann

Our furnace failed on one of the coldest days this past winter, and Mike from Oasis Heating & Cooling responded immediately. He came by quickly, assessed the situation, and helped us arrange a full furnace replacement without delay. The installation team—Damir and his son—were excellent: efficient, professional, and respectful of our home. They completed the work within a few hours, and the new system has worked flawlessly ever since. From start to finish, the experience was smooth, honest, and reassuring. Mike and his team clearly care about quality and customer service—no upselling, just straightforward help when you need it most. I highly recommend Oasis for any HVAC service, repair, or replacement. Five stars, no question!

Roxanne Corkin

Honest, efficient, friendly, reasonable fees. I cannot recommend highly enough.

Layne Turci

Had an EXCELLENT experience with Oasis plumbing. My AC went out right before this big heat wave. Every other tech I had out told me I would have to replace the whole thing, and they couldn't do anything for me until after the slate of 95+ degree days we had coming up. Some told me that it would cost thousands to fix my current problem. Oasis came out and 10 minutes later, my tech Damir tells me he's fixed my AC by replacing a part -- he carries a spare in his bag. So he's patched it for the summer -- a $300 solution when I was prepared to spend $8,000+. He also walked me through what was wrong with the system, what would need to be replaced eventually, and how to keep the ac going through the rest of the summer. I felt his price was very reasonable (he even took a little bit off because he misspoke when he told me the original price) and he was able to truly help me, not try to get more money out of me. The entire team at Oasis was very kind and accommodating -- they called me to offer me an earlier appointment slot and did their best to get me on the schedule on short notice.

Nancy Kalouch

i was impressed by the professionalism and the prompt scheduling of Oasis heating and cooling sale agent! The tech was punctual and courteous during my diagnostic visit. He took his time to explain the issue of my old system and the proper resolution choice. he did proper maintenance with no hassle nor hidden costs. I will definitely use them again!

Myra Vasilarakos

He was Great

Daniel Omastiak

Danny was incredibly helpful during his visit. He quickly identified our issue and helped resolve it during his visit. He was able to explain clearly how we can manage our unit moving forward. Bonus: he even offered some good tips for keeping our newborn cool during the hot summer months! Love a family owned business that will keep it real with you. They’ve won our business moving forward

Michael Marrion

On time, honest about what I needed and about what I didn’t. Family owned and operated. Hard to beat.

Polite, professional team, appeared to be an honest assessment and fix, finished job quickly. Wouldn't hesitate to use again.

Andrias Campbell

VIcky Golub

About ten years ago, I had a problem with my furnace, found Oasis by chance and have used the company ever since. Last year, Damir and his crew installed a new furnace and cooling system, and a year after he did preventive maintenance. Damir is always very professional, punctual, friendly and also gives you helpful tips about how to use the system more efficiently.
The company prices are fair and scheduling appointments is easy. Definitely recommend this company!

Response from the owner:Thank you, Vicky, for your wonderful feedback and for being a loyal customer for the past ten years; we're glad to hear that Damir and the team have provided you with excellent service and helpful tips! Your support and recommendation truly means a lot to us!

Sandra Saberman

The water heater in my rental unit broke on Monday and the great people at Oasis were able to come save the day early on Tuesday. Since it needed to be replaced, I was interested in getting a 40 gallon tank to replace the old 30 gallon tank that broke. Chris, one of their plumbers, worked with me over the phone and by text to determine whether a 40g would fit. (I sent photos and dimensions.) He was very patient, knowledgeable, and honest. Tuesday morning a couple guys from Oasis came over, fixed everything up, cleaned the area, and even moved some pipes around to make the 40 gallon tank fit. Everything is working perfectly so far. There's something about this business that inspires trust in me. They don't try to upsell. It just feels like a good old fashioned family business. Highly recommend.

Response from the owner:Thank you, Sandra, for your wonderful review! We're glad to hear that Chris and the team were able to help you find the perfect solution for your water heater. Your trust in us means a lot, and we appreciate your recommendation!

Angie Anderson

Damir and Amir were just here to look at my AC. They arrived on time, showed me what they were doing, answered all my questions, and took the time to explain to me how to best use my AC. It’s working well now. Thanks, guys!

Response from the owner:Thank you for the great review, Angie!

Damian F

I had a wonderful experience with Oasis. The service Tech (Naem) was on time, very professional and super friendly. Naem went out of his way to find out why my compressor(AC) wasn't turning over. He tested the system and said it was only a faulty capacitor. He could have easily told me I needed a new compressor and that it would have costed $1000 or more to replace. I can't tell you how greatful I am for Naem's honesty. I have been using Oasis for a couple of years now and there service is top notch! Thanks

Kristin P

I have been using Oasis Hearing & Cooling for years and they are consistently professional, responsive, and a pleasure to deal with. A few years ago I had a new heating system installed and not only was it completed in a timely manner, they cleaned the entire closet ( floor and all). They really are a pleasure to work with. Highly recommend!

Michael O

Could not be more grateful for the service today from Amir and son! They were early, explaining their findings in an understandable manner, able replacing the needed parts. There is no better then. These guys and the Oasis heating and cooling ! Really these are the guys to call for heating and cooling problems!! Tanks so very much

James Field

Working with Oasis Heating & Cooling has been a deeply frustrating and disappointing experience. After their work was completed, we submitted payment promptly. Unbeknownst to us, our owner also issued a duplicate payment — resulting in Oasis being paid twice for the same job.

Despite providing all necessary documentation, including transaction records and screenshots clearly showing both payments, the company has refused to issue a refund for the $1,400 overpayment. We've made every reasonable effort to resolve this, but they’ve been unresponsive and unwilling to do the right thing.

At this point, we’re at risk of losing over $1,400 due to their negligence and lack of accountability. I strongly urge others to avoid this company and choose a business that operates with honesty and integrity.

Andrea Zakrzewski

On time, efficient, friendly and cleaned up extremely well after air conditioner installation

Response from the owner:Thank you, Andrea, for your wonderful feedback; we're glad to hear our team was on time, efficient, and took care of the cleanup after your air conditioner installation! We are here for all of your HVAC and Plumbing needs!

Patricia M. Rios

Desperately needed a new furnace as it was dying right around the time Chicago was having extreme cold weather in February 2025. I shopped around and called a few places and felt all except Oasis where overpricing/taking advantage probably because I needed a new furnace. I wanted to get both furnace and air conditioning installed since they both needed to be replaced and I thought I might save on getting them both done. Mike from Oasis, called me and came that same day to evaluate my issue. He was so thorough and helpful and trustworthy. He was able to schedule
something within 3 days. The men from Oasis were amazing, prompt, professional and great workers. I would recommend them to anyone for their honest, professional demeanor, and quality in work.

Response from the owner:Thank you, Patricia, for your wonderful review! We're glad to hear that Mike and the team were able to help you with your furnace and air conditioning needs in such a timely and professional manner. Your recommendation means a lot to us! We are here for all of your HVAC and Plumbing needs!
