Customer Reviews

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.

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 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.

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.

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.

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.

**Great Service – Highly Recommend!** I had a great experience with Oasis Plumbing, Heating and Cooling. They recently serviced my heating system, humidifier, and radiant floor heating system. Joe and Damir arrived on time and were both professional, efficient, and very knowledgeable. They were thorough in their work and took the time to make sure everything was working properly. I also want to recognize Steve, one of their plumbers, who took the time to speak with me about a question I had regarding my radiant floor heating system. What impressed me most was that after our initial conversation, he gave it some additional thought and actually called me back with another idea about what might be happening. I really appreciated his initiative and follow-through. Overall, I was very pleased with the quality of their service and the level of care they demonstrated. I would definitely recommend Oasis!

Response from the owner:Thank you, Marcia! We truly appreciate your kind words and are glad to hear about your positive experience with Joe, Damir, and Steve. It’s wonderful to know that their professionalism and dedication made a difference for you. Your recommendation means a lot to us!

Oasis is a first class HVAC company. Oasis installed a new MagicPak unit for my condo in River North 1 year ago. Oasis completed the 1 year service as well. All of the services that Oasis provided were excellent. This includes system knowledge, system installation, office notifications for progress updates, check-ins for satisfaction responsiveness and price. If you need a new system, system repair or annual system service Oasis is your best choice!

Response from the owner:Thank you, Brian, for your kind words and for choosing Oasis for your HVAC needs; we truly appreciate your feedback and are glad to hear you had a great experience with our services!

I have been an Oasis customer (and fan) for over 20 years! I have only experienced the BEST service and professional care for all these years - their staff is excellent (and everyone has been there a long time so my experts keep coming back year after year). I feel known by their staff which gives me great peace of mind when they arrive to do a job…I know it will be done correctly, thoroughly, quickly, promptly and efficiently - and with a warmth and kindness that leaves me smiling. The consistency is so appreciated. I would never use anyone else!

Response from the owner:Thank you, Arlene, for being such a loyal customer for over 20 years and for your kind words about our staff and service; we truly appreciate your trust and support!

Great service! They came out quickly to replace my water heater and Steve and Amer went out of their way to fix a badly placed shutoff valve in a tight closet. I use Oasis for my HVAC too because they are willing to service the rooftop a/c.

Response from the owner:Thank you, L! We're glad to hear you were pleased with our service and that Steve and Amer were able to assist you with the shutoff valve. We appreciate your trust in Oasis for both your water heater and HVAC needs!

Furnace service: Mark was great- friendly and efficient. Called before my appointment window and gave me the specific time he would arrive, which I appreciated. AC service: Joseph was very friendly and efficient. He kept me updated on the work he was doing. I’ve used Oasis for years and am always impressed with their professionalism. Very reasonable prices on the HVAC services. Prior review:The work was done quickly and plumber was nice but quite expensive for a short job so I’ll go back to my previous plumber

Response from the owner:Thank you, Susan, for your feedback! We're glad to hear the work was done quickly and that you found the plumber nice, and we appreciate your honesty about the cost. We hope to still work with you for all your HVAC needs!

The OASIS team was fabulous in resolving our emergency and quickly installing a needed new compressor. The compressor was damaged when other workmen were working on a separate system at our house. We were imminently leaving the country. We urgently called Oasis. Mike quickly identified a new unit, ordered it and had it installed the next day. The installation team including Michael and others were so easy to work with and did a great job. THANK YOU, OASIS! Now we can leave the country for our trip with peace of mind! We will always trust you with our system needs! And when we needed them again this week, they were out immediately and addressed out needs. Thank you, Oasis! Much appreciated.

Response from the owner:Thank you, Jane! We're so glad to hear that our team was able to quickly resolve your emergency and get you ready for your trip. It's great to know that Mike, Michael, and the installation team provided you with excellent service. We appreciate your trust in us for your system needs!
