Air Conditioner Repair in Oak Brook, IL

Common Air Conditioner Issues

There are several common problems that can cause your air conditioner to stop working properly:

Refrigerant Leaks: If your AC unit is low on refrigerant, it may not cool your home effectively. Leaks can occur due to wear and tear or damage to the unit.
Frozen Evaporator Coils: When the evaporator coils become too cold, they can freeze over, preventing proper airflow and cooling.
Clogged Air Filters: Dirty or clogged air filters restrict airflow, causing your AC to work harder and potentially leading to system failure.
Faulty Thermostat: A malfunctioning thermostat can cause your AC to run inconsistently or not at all.

If you notice any of these issues or your air conditioner simply isn’t cooling your home as it should, it’s time to call in the professionals at Oasis Plumbing, Heating & Cooling & Cooling.

Customer Reviews

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.

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 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 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.

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 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.

Evan Berkey

They came right on time and were done very promptly. Left my HVAC system looking clean and ready to go!

Joshua Runnels

I had a great experience with Oasis. They were very fast and very professional.

Maura Barrett

I had a really positive and efficient experience with Oasis. The quote was easy to schedule as was the work that needed to be done. The team was very flexible with a few different proposals, and helped me troubleshoot an issue that came up when my HOA was being difficult about where the condenser could be placed. Their creative solutions were immensely helpful and got us much needed air-conditioning just before the summer heat waves. They also caught an issue that my electricians made, which saved a lot of headache in the future for other projects and to make sure that my unit would stay healthy.

Eric Yore

I was extremely pleased with my experience with Oasis! From the prompt scheduling to the expert service, an all around great experience. I had a 10:00 am appointment and the tech was running late. He had the courtesy to call and let me know he would be running late. Little thing, but much appreciated! Makes a huge difference. When he arrived he was very professional, knowledgeable, and completed the work in a timely manner. I will continue to use and recommend Oasis. I’ve had neighbors use Oasis as well, and they have also been pleased. Thanks!

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!

Oasis did an amazing job replacing my 20 year old HVAC unit today. Fernando, Michael, and their team were prompt, professional, friendly, and efficient.

A Ho

This company is incredibly responsive and professional. They installed two new furnaces and AC units in 2021 in our home. This wasn’t the easiest with one of the furnaces in the attic. They did an excellent job and the units have been working really well. Today, they did some maintenance service on the furnaces and again were friendly, super helpful and very knowledgeable. This is a great company to work with!

Response from the owner:Thank you, Joel! We're glad to hear that Craig and the team made your experience positive, and we appreciate your continued trust in us.

John Adler

Before calling Oasis, I had another company inspect our non-working AC. They diagnosed the issue as a faulty furnace circuit board. Since we had a similar problem in the past and replacing the circuit board didn’t solve it then, I asked the technician if he was certain. Although he said he was confident, they couldn’t get the part in a timely manner.

So, I called Oasis—an authorized American Standard dealer—and their technician, Naem, quickly ruled out the circuit board as the issue. He identified a shorted Y1 wire instead and had it repaired in under 30 minutes.

Huge thanks to Naem! Oasis will definitely be our go-to mechanical contractor moving forward.

Response from the owner:Thank you, John, for sharing your experience and for trusting Oasis with your AC issues; we’re glad Naem could quickly (and correctly!) identify the problem and get everything sorted out for you.

Kevin Galligan

Great job as always! Thanks - Mary and Kevin Galligan

Response from the owner:Thank you, Mary and Kevin! We truly appreciate your kind words and support. Always a pleasure to see you, and we look forward to the next visit!
