Customer Reviews

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.

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.

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 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 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.

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.

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.

Chris came to work on our plumbing and was excellent! We had a mysterious clog for months that our own attempts at routing hadn’t cleared. He came in, helped diagnose the issue, and then fixed it. The job ended up being more involved, but Chris ran out right away to get parts and had a whole piece replaced and working within a couple of hours. We felt the price was reasonable both for the time, parts, and work. We will definitely call them again!
Response from the owner: Thank you, Anneliese, for your kind words and for recognizing Chris's efforts in resolving your plumbing issue; we're glad to hear you found the service timely and reasonably priced, and we look forward to assisting you again in the future!

I believe this is the second time I’ve used this company. Always a pleasant experience. Scheduling was super easy and fast! My Tech, Naem, was professional and took the time to explain things to me and show me how to clear the pipe. He didn’t BS me or try to sell me anything. Would recommend and use Oasis again and again. Thank you!**Update: Jason serviced my furnace. Was quick and efficient. Fast service from the company. Requested a maintenance yesterday and was scheduled today at 8:30 AM.
Response from the owner: Thank you, Courtney, for your kind words and for choosing us again! We're glad to hear that Naem provided excellent service and that Jason was efficient with your furnace maintenance. We appreciate your recommendation and look forward to serving you in the future!

Mike responded quickly and luckily was nearby so came over pretty fast as well. He was off the clock but still came because I wouldn’t have heat on that cold winter night if my furnace didn’t get fixed. He also explained what went wrong and gave me some tips in case a similar situation occurs in the future. Was reasonably priced as he didn’t charge for the new fuse, overtime, etc. Will definitely use Oasis again for future HVAC needs!
Response from the owner: Thank you, Katrina, for your wonderful review! We're glad Mike was able to assist you quickly and provide valuable insights. Your support means a lot, and we look forward to helping you with your future HVAC needs!

Mike and his team at Oasis have been providing heating and cooling work for us for about 20 years. They recently solved a fairly complicated zone control issue and it really worked out well. Plus Oasis now does plumbing work and Chris took care of two plumbing problems of ours right away. Highly recommended!

My boiler kept overfilling. Found Oasis on Google. Text them at 6am. About 7:15 Danny was here. Found the problem and explained what had to be done. Oasis was very good about letting me know what was going on after the first visit. Danny came back the next day. Did the work in about 3 hours. Explained again what was done. I am pleased. I Would contact them again if needed.

We had a great experience and would highly recommend. Our furnace stopped working around 8PM in the middle of a Chicago winter. We called at least three different places before Oasis and the companies had said they couldn’t send someone out and left it at that. I spoke with someone from Oasis and he was friendly and assured me that our pipes would be fine through the night and would send someone out first thing in the morning and got us scheduled right away.Someone came in the morning and suggested that we replace our 23 yr old furnace since the replacement part would be 1/5 of the cost. We were able to get someone out a few hours later to replace our furnace and humidifier at a competitive rate. I really appreciate the ease of appt scheduling and their professional staff especially during a time where we were panicking a bit!
Response from the owner: Thank you so much for your positive feedback, Hillary! Our team is committed to delivering quality service, and your feedback is a great encouragement to us. We look forward to working with you again soon!

Oasis couldn’t have been better! Our boiler was leaking. I talked to a real (and friendly) person to book the appointments to inspect, order the correct new one and then replace.

I have used Oasis several times and have had exceptionally great service each time. The techs are kind, thorough, and knowledgeable.

I recently bought a condo and needed to get my furnace serviced for the winter. The first company I hired came out but told me they couldn’t service my furnace after seeing it was located in the ceiling. I called Oasis and their technician had no problem accessing and servicing my furnace. Later when I needed to change the filter in the furnace, it was hard for me to access and change. I called Oasis at 7 pm one night for help to get it changed. The technician Hani stopped by to change the filter for me the very next morning and Oasis didn’t even charge me! I’ve also hired a plumber through Oasis to fix an issue with my toilet. He was very helpful and I’ve had no issues since. I plan on using Oasis for all my HVAC needs.
Response from the owner: We are pleased that we have e another happy customer.Thank you for your feedback and your business.

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.Update: Just had them install a new furnace and was once again very pleased with the experience. Naem explained why we needed a new furnace and Fernando and Michael did a great job with the install. They were professional, polite and the job was done in a timely manner. After install, they registered our new furnace and sent us post-install documents. We feel like we are in good hands with Oasis.
Response from the owner: We appreciate your feedback and support.Thank you and we look forward serving you again in the future.

I am so beyond impressed with Oasis. Being a new business owner with TWO busted HVACs, it’s so stressful to find a trustworthy company to turn to. I am so grateful we went with Oasis. Daniel was incredible. He took videos and pictures to show me the issues with the machines. Daniel was in communication at every step in the process. Now sitting in our toasty cafe with Daniel and Oasis to thank!

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.
Response from the owner: Erika,Thank you for detailed explanation.We have a new system at we are still llearning.As usually ,we always look for improvements.
