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.

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.

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.

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.

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.

Dan Milligan

Oasis came through for us when our furnace went out in the middle of the night this January while our dog sitter was here and we were out of town. They showed up within 8 hours and installed a part to get it through the weekend until they could come back for the full replacement. A few months later, Damir returned to help install a new thermostat when the old one started acting up. Overall one of the better experiences I've had with a service company in my 10 years in the city. Hats off to the Oasis team, and thanks again to Damir.

Response from the owner:Thank you, Dan! We're glad we could assist you during such a crucial time and appreciate your kind words about our team. We'll be sure to pass along your thanks to Damir as well. Your positive experience means a lot to us!

Nathan Wiesehan

Joseph was super helpful and upfront about our system for our maintenance visit.

Response from the owner:Thank you, Nathan! We're glad to hear that Joseph provided you with helpful and transparent service during your maintenance visit. Your feedback means a lot to us!

Autumn Riggenbach

Update: During our AC maintenance appointment, the team discovered a severe leak. Once again, the technicians were incredibly kind and informative, walking us through all our options and the associated pricing. Since the unit is 12 years old and had not been properly maintained before we purchased the home, we decided to replace it. They scheduled the replacement for the very next day, refunded our maintenance fee, and provided a very fair quote that was on the lower end of what we found in our research. I truly cannot recommend this company enough! I feel so much better knowing our entire HVAC system was installed by their team and will continue to be maintained by them annually. —— Such a great experience! Learned about them through referrals in Lakeview. We closed on our apt on Tuesday. I was able to have someone come out on a Wednesday to check out the furnace and dehumidifier. The team was able to replace everything by Friday. I was nervous about up charges with the cold weather just kicking off, but instead, Oasis gave me a discount and helped bring everything up to code (for free or extremely low costs). Highly recommend! I will be purchasing their 2x a year services too. The guys were such gentlemen, on time and super clean. Thank you!!

Response from the owner:Thank you, Autumn! We appreciate your kind words and are glad to hear you had a great experience with our team. We look forward to serving you again with your biannual services!

Zachary Jones

Joseph was great! Super friendly and knowledgeable. Showed up on time, quickly diagnosed and fixed two AC units and was very reasonable about pricing for service and two replacement parts.

Response from the owner:Thank you, Zachary! We're glad to hear that Joseph provided friendly and knowledgeable service while efficiently fixing your AC units. We appreciate your feedback on our pricing as well!

Oasis did it again! Of course my AC goes out days before I leave for a trip. I call Oasis and make a last second visit to fix my AC. I cant recommend these guys enough!

Response from the owner:Hi Mel! Thanks so much for making the time to leave us such a glowing review; we look forward to keeping you a happy customer! Sincerely, Your Oasis Team

Mary Catherine Bort

Response from the owner:Thank you, Rana, for your kind words; we truly appreciate your support. Thank you for choosing us again and again!

John Mickelson

Joseph came, explained everything I could've needed to know, showed me pictures of the clog, cleaned it out, couldn't have been easier. This is the furnace they installed 10 years ago, we haven't had any issues in 10 years, and this would have been prevented of we got regular services! Happy to support this local company and they do great work. Summer '26 update. Fernando and Joel installed a new AC unit as ours was over 20 years old and started making lots of me noises. Reasonable price, quick service, the unit has been working great for a few months now.

Response from the owner:Thank you, John! We're glad to hear that Joseph provided you with such thorough service and that your furnace has been performing well for a decade. We appreciate your support of our local business and look forward to continuing to serve you!

Steven Meier

The Oasis team is super responsive and their expertise in ductless/heat pump systems was critical. They remedied errors in our original installation (done by our former general contractor) and now our heat pump system is working great.

Response from the owner:Thank you, Steven! We're glad to hear that the Oasis team was able to assist you and resolve the issues with your heat pump system. Your satisfaction means a lot to us!

Fast, efficient and friendly service! Called Saturday late afternoon and our AC was working again by 9am Monday morning.

Response from the owner:Thank you, M! We're glad to hear you had a fast and friendly experience with our service. Your satisfaction is important to us, and we appreciate your feedback!

Jodi Slaght

Oasis is very helpful and quickly responds to issues. I appreciate their fair and honest approach - they will tell us when problems are associated with systems that they install/repair and when they are not. I greatly appreciate the candor.

Response from the owner:Thank you, Jodi, for your kind words and for highlighting our team's commitment to professionalism and responsiveness; we’re glad we could assist you with your water heater and A/C and we're here for all your HVAC and plumbing needs!
