Our highly-trained technicians are equipped with the knowledge and tools necessary to diagnose and fix any issues with your ductless system, ensuring your comfort and peace of mind.

Common Ductless HVAC Issues We Repair

Ductless HVAC systems, also known as mini-split systems, are becoming increasingly popular in Chicago homes and businesses due to their energy efficiency and flexibility. However, like any HVAC system, they can experience problems that require professional repair. Some of the most common issues we encounter include:

  • Refrigerant leaks: Low refrigerant levels can cause your system to lose cooling capacity and efficiency.
  • Electrical problems: Faulty wiring, loose connections, or malfunctioning components can lead to system failures.
  • Clogged air filters: Dirty or clogged air filters can restrict airflow and cause your system to work harder than necessary.
  • Frozen evaporator coils: When the evaporator coils freeze, your system will not be able to cool your space effectively.
  • Malfunctioning thermostats: A faulty thermostat can cause your system to cycle on and off frequently or fail to maintain the desired temperature.

Our experienced technicians are well-versed in diagnosing and repairing these and other issues, ensuring that your ductless HVAC system is running at peak performance.

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.

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 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.

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.

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.

Quick and responsive service! Highly recommend Joseph!
Excellent service from Oasis! Mark came by this morning and did a fantastic job. He was extremely thorough, professional, and knowledgeable. He took the time to walk me through how the system works, answered all my questions, and provided valuable insight into some of the issues my tenants had been reporting. Mark was clear, patient, and very informative throughout the entire visit. I highly, highly recommend him! This was my first experience using Oasis, and so far, I'm extremely impressed with the quality of service. Excellent job, and thank you, Mark!

Vaha and Anel installed my new HVAC system THIS MORNING! It took them less than 4 hours. They were quiet, efficient and effective. They treated my dog, my Mom and I with the utmost respect. Upon completion they walked me through the furnace, the condenser and my programmable thermostat. Mike got back to me right away and we were scheduled within 48 hours. Joseph was on time and thoroughly explained everything. He also explained Oasis offers extended warranty simply by scheduling tegular service checks. Dan came to check our furnace out. He was prompt and quick. He gave me a couple reminders and was even kind to our dog!
Response from the owner:Thank you, Rachel! We appreciate your kind words about Vaha, Anel, and Mike. It's great to hear that you had a positive experience with the installation and that they took the time to walk you through everything. Your satisfaction means a lot to us!

**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!
