Customer Reviews

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 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 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 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.

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.

Shane H.

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.

Joseph did a fantastic job performing a maintenance check on my furnace. Very friendly, knowledgeable and polite. Took time to explain everything to me about the inter workings of a furnace. Came on time, worked quickly but thoroughly. Hopefully my kids learned a thing or two as well! Thanks again!

Unfortunately we had a terrible experience with them. While the technicians were friendly, they did not fix our issue, 3 days and a dangerous gas leak later, we finally had our heat back. In between this mess the owner didn’t even return our calls and no apology when we had to take our kids out of the house for the night. It was during the bitter cold weekend and had to buy space heaters, and then were charged a huge amount for their mistake. I would not recommend if you have an older boiler or unit. I think the lack of experience showed.

Response from the owner:You must be kidding me.
Totally disagree with your statement.
We tried to help you saving your old boiler with minimum charge.
We lost money on this call, but it wasn’t about money.
It was brutally cold and our job is to help people in those situations.
It’s not lack of experience.Its lack of trying to fix something old..We were responding on every your call and making sure that the boiler is fixed.
We came on Sunday and next day after hours in attempt to fix it.You were informed on Sunday that we don’t have that part and the stores are closed .
We never intended to let you down.
Thank you for one star review .
It’s time to replace that boiler.

Joseph was excellent service technician and will want him to assist us again!! 00pm

Chad Osborne

Our unit was having trouble keeping up with the sub-zero temperatures. Damir was excellent. He adjusted the airflow and recommended a different filter. Problem solved.

He didn't believe me when told him its blowing cold air. He stood there hand on the vent trying to convince us it's getting hot. It's lukewarm at best. Waste of money. $165 down the drain. That should be illegal. Didn't suggest a part replacement. Only suggested to buy a $6000 new furnace. It's short cycling that's not a broken furnace that's new parts wear and tear situation. I will never recommend Oasis to anyone.

Nancy Levin

What a great experience: replaced the hot water heater, sump pumps - going above and beyond with their care and attention to the issues I hadn't even noticed. Very easy to work with.

MatthewJN

We hit furnace trouble on one of the coldest days of the year, and Oasis still got us in the same day—on-site within two hours of my call. Naem was our technician and was fantastic: kind, quick to diagnose, and had the heat running again in under 30 minutes. They also installed our rooftop A/C and did an excellent job. We’re really grateful for the whole Oasis team and their great service. Highly recommend them to anyone in Chicagoland.

Michael Berman

I know I can always count on Oasis when I have a problem! Joseph came out and was helpful and efficient fixing our furnace, which is more important than ever during the dead of winter! He even helped fix a closet door that helps keep the furnace shielded from my kids. Really grateful to Joseph and the entire Oasis team for another successful visit!

Garrett Fenley

Joseph was quick and efficient on getting my heat back in order. He explained everything well and went above and beyond

Excellent, fast service by Fernando on a bitter cold Sunday. He addressed our issue quickly and charged us the fee he stated on the phone, which was one of the better prices we found. Will be calling them again.

Joanna Clark

Our heat went out mid winter. Oasis sent someone out to diagnose the problem and replace the furnace the very next day. Everyone from their team was super kind and helpful. Fernando and Joseph did the install. They were fast, friendly, and explained everything to me to make sure I knew what was going on.

James Hughes

Great experience with Oasis. When my furnace stopped working they were able to have someone (Danny) come out the next day. Danny explained everything very well and gave me estimates to replace the broken inducer motor and to to replace the whole furnace. I appreciated that he wasn't pushy in any direction but gave me his honest take.

I had initially decided to replace the whole system, but then changed my mind and decided just to replace the part. When I called the office and asked if it was okay to change the plan, Chris was very understanding of my situation and I did not get a hard time about it. I really appreciated that.

Joseph came out the next day to replace the motor, and like Danny did a great job of explaining things and seemed very honest.

Overall every interaction I had with Oasis personnel was very positive and I felt like I was getting honest expertise. They were all very kind as well.

Drew Kidder

We had our HVAC control board die on us in the middle of January. Oasis was incredibly responsive. They gave us a fair price with quality products. Fernando, Michael and Joseph did the install in a day, with excellent communication and attention to detail. We’ve used Oasis in the past and will continue to use them in the future. Just a top notch level of service.

Response from the owner:Drew,
Thank you for your review.
Oasis team.

Joseph, Damir, and Amir did an amazing job. The staff was on time knowledgeable and completed the full furnace replacement in 4.5 hours. They told me all about the unit and explain everything i needed to know. Will definitely use them in the future.

Sydney Dusel

Tech and installation members were friendly, knowledgeable, and efficient. The company is extremely easy to reach / provides fair pricing. Our heat went out on 12/30 and someone was out here the next morning on New Years Eve to check it out. Highly recommend for maintenance and repairs!

Jon Heise

Joseph did a great job. Knowledgeable and fast!

Carson Heims

Joseph we extremely helpful and gave an in depth explanation of the systems/issues

Jennifer Geiman

Team Amir was great! Stayed til everything worked even the day after Xmas. Couldn't recommend them enough.

Joe Davis

Damir, Mark, Joseph, Vaha & Anel installed our new HVAC system and we’re all so profesional and polite! It was a big job and it got done really quickly and felt like they were barely here. We also had duct cleaning which was very though, and Chris did some plumbing and did a fantastic job.

Really blown away by the whole company including Marc the owner who did our quote for the whole thing. Will use for all my hvac needs going forward

Ricky Tang

we have been using Oasis for more than 10 years. they replaced our furnace and AC unit through those years. we have never had any problem with heating or cooling since then. Oasis technicians and managers are courteous and knowledgeable. like today, Joseph, spent extra time to show us how our furnace works and the internal safety features that it has. we really appreciate that!

Rach Ski

Oasis was the quickest to be able to get to us when our heat went out at 9 pm on the coldest day of the year. Fernando and Michael were out the next day with a new unit and went above and beyond! When noticing how bad the a/c unit was with corrosion and mold they were able to replace that as well, timely, and all for a fair price! They were on time, professional, quick, and skillful-thank you!

Sam Hammett

Oasis always delivers! After doing repair work on our AC last year - because the company that did the install wouldn’t return our calls for service - we knew they were the right call for our furnace!

Our furnace motor went out a few days ago - during the winter/a week before Christmas! What a nightmare. Oasis was able to come out first thing the next morning without charging us for an emergency call! Naheem was our repair tech and within 15 minutes he diagnosed the problem and gave us a couple of options with cost estimates. He provided his professional opinion and it felt genuine and unlike a sales pitch!

2 days later, Serge and Harvey came to replace our furnace! They were incredibly kind, respectful and efficient - arriving on time and finishing within the estimated time window. At the end, they did a walkthrough of the new furnace, answered questions about the filters, and even took time to re-affix and correct the settings on our Nest thermostat (that we fully messed up before calling them).

So grateful to find service we can trust!

Update: I continue to use Oasis for ongoing maintenance and repair. This year Joseph came out for the annual check in. He was very professional, went over the system and helped me to better heat my home for the winter. Thank you!

I have been using Oasis since 2019. They are reliable, efficient, and their prices are reasonable. The customer service is amazing.

Joseph did a great job!

Aviva Waldman

Joseph was great! He helped explain to me what was wrong with my furnace and what my options were.

Patrice

Well, had Oasis out in November for a new furnace and today for a hot water heater that died (and leaked). They are always responsive and Chris did a great job answering my questions. I didn't realize they have a licensed plumber on staff to do this work. Very helpful!

Zach Kennedy

Great service from Joseph! Diagnosed the issue and was very transparent throughout the whole visit.

Ethan York

Easy and courteous. Joseph was efficient and did a great job explaining my furnace system to me and any issues he identified and how to avoid potential issues. Was very satisfied with Oasis.

A Ho

This company is incredibly responsive and professional. They installed two new furnaces and AC units in 2021 in our home. This wasn’t the easiest with one of the furnaces in the attic. They did an excellent job and the units have been working really well. Today, they did some maintenance service on the furnaces and again were friendly, super helpful and very knowledgeable. This is a great company to work with!

Just an update, 12/9/25. We had the units serviced today and Joseph was great. He texted before he arrived allowing me time to put the dogs in kitchen. He was right on time, quick and efficient, and he communicated really well. Plus, he answered all my questions. Really like this company!

Response from the owner:Thank you for your wonderful feedback! We're glad to hear about your positive experiences with our team and that the installations and maintenance went smoothly. Your support means a lot to us!

Jon _

Fernando and Michael did a fantastic job with the removal and install of our new furnace. Had some helpful tips on operation and maintenance of the new system. Would likely recommend. Very professional and courteous. Great work!

Fam A

This is my third experience having Oasis help with our HVAC and they continue to deliver great results. Michael and Joseph went above and beyond to work on our system. The were super knowledgeable and helpful, and great at communicating and troubleshooting to get our system and keep it in tip-top shape! We also signed up for their annual maintenance program and that will continue to keep our HVAC running smoothly.

Curtis Malasky

Hi bought a high efficiency furnace from Oasis in 2021. Since then I've had one service call that went great. Today I can home from a trip to find a house without heat. It was snowstorm season, and the crew were very busy, but in lieu of a service call, they were able to walk me through a very easy solution which worked great. They've always been very prompt and skilled. *****

miguel ortiz

Very quick and about 5000 cheaper than the first estimate. Fernando was good

Joseph came out and provided good info and troubleshooting. Good service

Kristin Schrepferman

Thank you to Danny! He was friendly, prompt, knowledgeable and professional. He patiently troubleshot my radiant heat issue, fixed it, and followed up to make sure everything was working properly as the system heated up over several hours. Oasis will be my first call for any future plumbing, heating or cooling needs. The office was also great—easy to reach, quick responses, and simple scheduling. Excellent service at a fair price.

Response from the owner:Thank you, Kristin, for your 5-star rating! We appreciate your support.
