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.

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.

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.

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.

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.

Oasis showed up when they said they would be there and got the work done quickly and without the need for follow up. I had them replace a furnace in 2024 and an AC unit in 2026.

John Dungan

I will never call another service. Everything about Oasis is 5 stars. When I called them just to get information about their services and schedule an appointment, the customer service representative was informative and courteous. I also delightfully surprised that they could schedule a 7 AM appointment so I didn’t have to miss any work. On the day of my appointment, Joseph arrived at 7 exactly! He was also courteous, informative, and efficient. He sealed the deal on me being a lifetime customer of Oasis. I highly recommend everyone give this outfit a lot of consideration when deciding who to call. You won’t regret it.

Victoria Vanek

We had an excellent experience with the AC technicians from Oasis. They quickly investigated the issue with our AC system early in the morning and were able to install a brand-new unit the very same day. During a heat wave, their fast response saved us from having to spend the day and another night in an unbearably hot condo. The team was extremely courteous, professional, and efficient throughout the entire process. We truly appreciated their responsiveness, clear communication, and quality work. Highly recommend Oasis for their outstanding service!

Response from the owner:Thank you, Victoria! We're glad to hear that our technicians provided excellent service and quickly resolved your AC issue during the heat wave. Your appreciation for their professionalism and communication means a lot to us. We look forward to serving you again!

Update on May 2026: Oasis has a great plumbing team now! Thanks Steve and Amer for the smooth water switch change. They are very knowledgeable and patient. Update on April 2026: had my second appointment with Joseph, who was absolutely amazing. I can always learn something useful from him to better care for my system. Highly recommend him and Oasis! Glad I found Oasis to help me maintain my home heating and cooling system! From booking the first visit, to communicating the arrival time, Chris went up and above. My technician Joseph showed up on time and answered all my questions regarding my home furnace and humidifier. Will be working with them annually moving forward!

Karen Otto

Oasis arrived on time to dismantle my 16 year old AC and carried the new AC up 4 flights in a tight staircase, all professionally done. The installation was completed in 4 hours and the result vastly improved not just the coolness of our home but the noise factor, it is unbelievable how much quieter with the new system. This is my 2nd experience with Oasis and I highly recommend and trust their team.

Response from the owner:Thank you, Karen, for your wonderful feedback! We're glad to hear that our team was able to provide you with a smooth installation experience and that you're enjoying the improved comfort and quiet of your new AC. We appreciate your trust and loyalty to Oasis!

Oasis is the best heating and cooling company to work with in all of Chicagoland! I will only work with these guys. They are professional, kind and considerate, and truly understand heating and cooling.

Response from the owner:Thank you so much! We know every HOA is different, and we are glad we could get the paperwork figured out so quickly. Thank you so much, and we hope to work with you again this winter!

Evan Westerfield

I have been using Oasis for several years. They installed my Space Pak a/c system, as well as (later) a new hot water heater. They service my boiler and the Space Pak and the hot water heater, on a regular basis. Communication is always excellent. Technicians are knowledgeable and friendly. And those few times when I've had an emergency, they've been there quickly (and times where I've had concerns, only to determine that it was my stupidity, they haven't charged me for the visits). Really pleased with the service!

Response from the owner:Thank you, Evan! We truly appreciate your loyalty and are glad to hear you’re satisfied with our communication and service. It's great to know our team has been there for you during emergencies. Your kind words motivate us to keep delivering excellent service!
