On the job since 1997, Oasis Heating & Cooling resolves all types of issues with heating and cooling across Chicago, IL and the surrounding areas every single day.

Restore Efficiency to Your Ductwork Today

Flaws in the ductwork allow conditioned air to escape. The heating/cooling unit then needs to run longer and use more energy to satisfy thermostat settings. There’s the very real possibility of outside contaminants, such as VOCs, getting drawn into the system and spread into the living space. In the majority of homes, up to 30% of heated/cooled air is lost due to ductwork leaks. Make your Home an Oasis with ductwork sealing from Oasis Heating & Cooling. We offer same-day/next-day scheduling across Chicago, Elmhurst, Bensenville, and Addison, IL.

Customer Reviews

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.

Megan R.

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.

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 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.

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.

So glad they're expanding their service offerings!Our A/C went out in the middle of summer (of course) and, of all the companies I reached out to for help, Mike from Oasis was the first to come out and assess the situation (within an hour).

Sneh SukhadiaSneh Sukhadia ★★★★★ I will say Hani from Oasis is by far one of the most professional and kind hearted technicians I have ever come across (I’ve worked with many). Not only was he extremely transparent when explaining the situation that was going on with my water boiler but also throughly checked through all the vents on the property and gave me such good advice on how to prevent future malfunctions and how to maintain more heat throughout my residence. Truly blown away by his professionalism, kindness, and extremely rare honesty. He didn’t try to over sell me on anything or have me pay for any services that I didn’t require or need. Please give this man a raise and some shares of the company because he is truly a one in a million type of technician.Emily HEmily H ★★★★★ Oasis is great!
