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

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.

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 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.

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 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.
Oasis heating and cooling, Anel & Vaha were very thorough, efficient, and made sure everything was working correctly. They explained on what they did and provided great information about our new furnace. Updated: Joseph from Oasis came for an AC maintenance. I told him that the unit has been making more noises than normal. He went above and beyond to resolve the issue.
Response from the owner:Thank you for such a nice review and feedback.

I have used Oasis services for about 12 years, and I have always been very happy with the quality of their work and the knowledge and professionalism of their staff. I have met the owner, Mike, who helped when my HVAC systems needed to be replaced, and I can confirm their culture of professionalism starts at the top.
Response from the owner:Thank you, Marla, for your long-term support and kind words. We're glad to hear that you've consistently enjoyed our services and appreciate the professionalism of our team, including Mike. Your feedback means a lot to us!

We had Oasis come out to take a second look at an older AC system, and the experience was great. They were thorough, straightforward about what they were seeing, and took the time to explain the different options without making it feel like a hard sell. I especially appreciated the conversation around replacement, sizing, and what made sense for an older Chicago home rather than just giving us a number and moving on. Very helpful and professional experience.
Response from the owner:Thank you, Mr. Burnett, for your wonderful feedback! We're glad to hear that you had a great experience with our team and appreciated the thoroughness and professionalism in addressing your AC system. Your satisfaction means a lot to us!
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.
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!
