Oasis Heating & Cooling Offers Seasonal Maintenance Plans

Ductless HVAC offers unmatched versatility. Compact components, flexibility of location, and non-disruptive installation resolve just about any comfort challenge. Whether you’re renovating, adding on, or targeting one or multiple rooms, consider the many advantages of a ductless air conditioner or heat pump. Oasis Heating & Cooling provides installation, repairs, maintenance, and a full array of ductless services in Chicago, IL and the surrounding areas, typically completing all jobs in a single day.

Ductless HVAC Services from Oasis Heating & Cooling

The installation of a ductless mini- or multi-split system avoids tearing down walls, disruption, and mess. Little more is required beyond a three-inch hole in an exterior wall. An outdoor compressor (operating so quietly, you won’t be certain it’s running) links to lightweight, streamlined air handlers mounted up high on the wall or cassettes set into the ceiling. Surprisingly powerful and wonderfully energy efficient, the ductless system delivers heating and cooling wherever you want or need it.

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 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.

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.

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 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.

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!

Oasis Heating and CoolingExcellentOasis Heating and Cooling4.9 Based on 516 reviews fromSee all reviews review us onellen eganellen egan ★★★★★ Valerie NichollValerie Nicholl ★★★★★ Jane MorsonJane Morson ★★★★★ Oasis Heating and Cooling has installed 3 furnaces and 2 air conditioning systems in our 3 flat over the last two years. They offer top quality equipment at very competitive prices. By purchasing their maintenance contracts, you double the parts warranty from 5 to 10 years on equipment you purchase through them. Installation is professional and efficient. Anel and Vaha just installed an air conditioning unit and they finished well ahead of schedule, were personable, professional, and didn't make a mess (very important to our tenants). They take pride in their work. The owner of Oasis participates in all aspects of the business and is a pleasure to work with. Highly recommend!Dave HorsteinDave Horstein ★★★★★ I noticed our AC unit wasn’t working around 9:45PM and gave Oasis a call. Within minutes I had a text from Mike saying he can come at 8AM the next day. Sure enough, Mike showed up and quickly diagnosed the issue. He also cleaned the unit and checked it for other problems. The whole experience only took about 30 minutes. Thanks, Mike!Gayle VictorGayle Victor ★★★★★ Once again Oasis was incredibly responsive to my request for service! This time it was the A/C, and Damir came the next day. It wasn't immediately obvious what was wrong, but he patiently took things apart, found the trouble, and had the part with him to fix it. He explained how to do upkeep and took the time to get the condenser in shape for me, all at a reasonable price.. This is the second wonderful experience I've had with Oasis, and now I wouldn't even consider calling anyone else!!Response from the ownerDear Gayle, Wow! Thank you so much for the feedback! We appreciate your business and hope to see you again this spring for preventative maintenance! Kristen PetersKristen Peters ★★★★★ Prompt customer service, professional tech, quick work. Highly recommend.Response from the ownerThank you so much, Kristen. We are happy to help and look forward to helping with maintenance again in the future! Shoshana CooperShoshana Cooper ★★★★★ very good servicevery professional and effecientResponse from the ownerThank you so much for the review, Shoshana! We have always enjoyed working with you and look forward to working with you for years to come! Lisa EhrhartLisa Ehrhart ★★★★★ Response from the ownerThank you, Lisa! Asif RajanAsif Rajan ★★★★★ Been working with this team for 15 years and i have never worked with any one better. They are the best in their job. Highly recommend. Thank you guys.Response from the ownerThank you so much, Asif! We value our long time clients, and want to give you the absolute best. We are happy to help, and look forward to doing your maintenance this winter! David LennieDavid Lennie ★★★★★ When we turned on our central air this season, it didn’t seem to be working at all — it would say it was running but either the air coming out wasn’t cooled or there wasn’t any air coming out at all.We subscribe to competing company’s monthly maintenance program for our HVAC and plumbing, and they’d tested and passed our unit only a month earlier. I had them come back and they diagnosed the problem as a likely refrigerant leak — they explained how they’d go about fixing it and the cost to repair but highly encouraged us instead to buy a whole new system from them — repair cost ~$2500, replacement cost <$10000!I decided to get a second quote and found Oasis. I liked that they specialize in heating/cooling, and their refrigerant leak repair process sounded much more thorough and was quoted for about the same as the other company. So I went with Oasis because they gave me more confidence that they could fully fix the problem.They were available within days. The morning of the service, they called to say that they’d had a bunch of their technicians call in sick so they’d be 2 hours later, which was fine — I was just happy that they gave me the heads up so early in the day. They arrived on time at the later time and spent 2 hours testing, locating, and repairing the refrigerant leak. They were incredibly professional and thorough and our HVAC is back to 100% working order. As an added bonus, they gave us a discount because they’d had to arrive 2 hours later than originally planned!Excellent service and communication across the board. They deserve all of their 5-star reviews!Response from the ownerThank you so much, David! We know your appointment did not go as smoothly as we would have liked, because when it rains, it pours, but you were so understanding and we appreciate it so incredibly much! Thank you for the amazing review, and we hope to come help maintain your system next year. And right on time, too!

We hope to help you with maintenance next year! Wai-Ling WengWai-Ling Weng ★★★★★ Oasis has always been responsive, prompt, and reliable. We have been using them since 2021 for AC related issues. I remembered my AC broke down on the hottest day of the summer last year. With one phone call, they were able to send a technician immediately on the same day. Harvi was very knowledgeable and friendly. He diagnosed quickly and replaced with a new part.A few days ago, my almost 20 year old AC finally decided to retire. The first thing came up to my mind is calling Oasis. The owner, Mike came out the next day during their busiest time, he explained the situation and gave me a great deal on both AC and furnace. Since my furnace is almost 20 years old and been having some issues lately, we decided to replace both based on recommendations from multiple people. Mike was able to provide all necessary documentation to our condo association. We were able to get an appointment within 3 days. He sent Harvi and 2 other guys to install the new units today. Harvi and his team did an amazing job. The whole job was done in less than 7 hours (7:30am to 2:30pm) and left no trace behind. Harvi even explained thoroughly to me how to operate the new equipment and provided suggestions on how to maintain. I would highly recommend Oasis to anyone.Response from the ownerThank you so much, Wai-Ling! We were glad we were the first team you thought of when you needed help. We were happy to get that replaced and glad we could do such an incredible job. Thank you for the amazing review, and we can't wait to help maintain your new system for years to come! Eric DeSantis (Super Edco)Eric DeSantis (Super Edco) ★★★★★ Nice group of workers doing a solid job, they were able to swap out our aging HVAC in a tight space with little interruption.Response from the ownerThank you, Eric!
