Air Conditioning Replacement in Addison, IL

When the summer heat strikes in Addison, IL, you need a reliable air conditioning system to keep your home comfortable. If your current AC unit is struggling to keep up or has reached the end of its lifespan, it may be time to consider an air conditioning replacement. Oasis Plumbing, Heating & Cooling & Cooling, serving our customers in Chicago, Elmhurst, Bensenville, and Addison, IL for over 20 years, is here to help you make the right decision for your home and budget.

Signs You Need an AC Replacement

There are several indicators that your air conditioning system may need to be replaced:

Age: Most AC units last between 10-15 years. If your system is approaching or has surpassed this age, it’s time to consider a replacement.
Frequent repairs: If you find yourself constantly calling for repairs, it may be more cost-effective to invest in a new system.
Increased energy bills: As your AC unit ages, it becomes less efficient, leading to higher energy consumption and utility bills.
Uneven cooling: If some rooms in your home are too hot while others are too cold, your AC system may be struggling to distribute air evenly.
Strange noises: Unusual sounds like grinding, squealing, or rattling can indicate serious issues with your AC unit.

Benefits of a New Air Conditioning System

Replacing your old air conditioning system with a new, energy-efficient model offers numerous advantages:

Improved comfort: A new AC unit will provide more consistent and even cooling throughout your home.
Lower energy bills: Energy-efficient systems consume less power, resulting in lower utility costs.
Enhanced air quality: Newer AC units often feature advanced filtration systems that help remove allergens, dust, and other pollutants from your indoor air.
Quieter operation: Modern air conditioning systems are designed to run more quietly, ensuring a peaceful home environment.
Increased property value: An updated HVAC system can be an attractive selling point if you decide to put your home on the market.

Choosing the Right AC Replacement

When selecting a new air conditioning system for your Addison, IL home, there are several factors to consider:

Size: It’s crucial to choose an AC unit that is properly sized for your home. Our experienced technicians will perform a thorough evaluation to determine the optimal system for your space.
Efficiency: Look for a high SEER (Seasonal Energy Efficiency Ratio) rating, which indicates better energy efficiency and lower operating costs.
Features: Consider additional features like programmable thermostats, zoning systems, and smart technology for enhanced comfort and convenience.

Customer Reviews

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 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.

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.

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.

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.

Oasis Heating and Cooling

Based on 752 reviews

About ten years ago, I had a problem with my furnace, found Oasis by chance and have used the company ever since. Last year, Damir and his crew installed a new furnace and cooling system, and a year after he did preventive maintenance. Damir is always very professional, punctual, friendly and also gives you helpful tips about how to use the system more efficiently.
The company prices are fair and scheduling appointments is easy. Definitely recommend this company!

Sandra Saberman

The water heater in my rental unit broke on Monday and the great people at Oasis were able to come save the day early on Tuesday. Since it needed to be replaced, I was interested in getting a 40 gallon tank to replace the old 30 gallon tank that broke. Chris, one of their plumbers, worked with me over the phone and by text to determine whether a 40g would fit. (I sent photos and dimensions.) He was very patient, knowledgeable, and honest. Tuesday morning a couple guys from Oasis came over, fixed everything up, cleaned the area, and even moved some pipes around to make the 40 gallon tank fit. Everything is working perfectly so far. There's something about this business that inspires trust in me. They don't try to upsell. It just feels like a good old fashioned family business. Highly recommend.

Angie Anderson

Damir and Amir were just here to look at my AC. They arrived on time, showed me what they were doing, answered all my questions, and took the time to explain to me how to best use my AC. It’s working well now. Thanks, guys!

Response from the owner:Thank you for the great review, Angie!

Damian F

I had a wonderful experience with Oasis. The service Tech (Naem) was on time, very professional and super friendly. Naem went out of his way to find out why my compressor(AC) wasn't turning over. He tested the system and said it was only a faulty capacitor. He could have easily told me I needed a new compressor and that it would have costed $1000 or more to replace. I can't tell you how greatful I am for Naem's honesty. I have been using Oasis for a couple of years now and there service is top notch! Thanks

Kristin P

I have been using Oasis Hearing & Cooling for years and they are consistently professional, responsive, and a pleasure to deal with. A few years ago I had a new heating system installed and not only was it completed in a timely manner, they cleaned the entire closet ( floor and all). They really are a pleasure to work with. Highly recommend!

Michael O

Could not be more grateful for the service today from Amir and son! They were early, explaining their findings in an understandable manner, able replacing the needed parts. There is no better then.

James Field

Working with Oasis Heating & Cooling has been a deeply frustrating and disappointing experience. After their work was completed, we submitted payment promptly. Unbeknownst to us, our owner also issued a duplicate payment — resulting in Oasis being paid twice for the same job.

Despite providing all necessary documentation, including transaction records and screenshots clearly showing both payments, the company has refused to issue a refund for the $1,400 overpayment. We've made every reasonable effort to resolve this, but they’ve been unresponsive and unwilling to do the right thing.

At this point, we’re at risk of losing over $1,400 due to their negligence and lack of accountability. I strongly urge others to avoid this company and choose a business that operates with honesty and integrity.

Andrea Zakrzewski

On time, efficient, friendly and cleaned up extremely well after air conditioner installation

Response from the owner:Thank you, Andrea, for your wonderful feedback; we're glad to hear our team was on time, efficient, and took care of the cleanup after your air conditioner installation! We are here for all of your HVAC and Plumbing needs!

Patricia M. Rios

Desperately needed a new furnace as it was dying right around the time Chicago was having extreme cold weather in February 2025. I shopped around and called a few places and felt all except Oasis where overpricing/taking advantage probably because I needed a new furnace. I wanted to get both furnace and air conditioning installed since they both needed to be replaced and I thought I might save on getting them both done. Mike from Oasis, called me and came that same day to evaluate my issue. He was so thorough and helpful and trustworthy. He was able to schedule
something within 3 days. The men from Oasis were amazing, prompt, professional and great workers. I would recommend them to anyone for their honest, professional demeanor, and quality in work.

Response from the owner:Thank you, Patricia, for your wonderful review! We're glad to hear that Mike and the team were able to help you with your furnace and air conditioning needs in such a timely and professional manner. Your recommendation means a lot to us! We are here for all of your HVAC and Plumbing needs!

The Oasis team could not have provided a better experience.

Really appreciated the transparency, ease to work with, and pricing. Absolutely recommend!

Oasis Heating & Cooling did a great job installing a new AC system and a new furnace for me. Their pricing was fair, and they were professional and prompt throughout the process. Hani was excellent as the point person for the entire project, and Fernando, Damir, and Michael did a great job installing the system. I strongly recommend Oasis Heating & Cooling.

Keith Forshaw

I have had very good experiences with Mike and his team over the years at Oasis HVAC. A few years ago when we first moved into the house, another HVAC company provided maintenance to the system while disconnecting the overflow drain switch on the AC coil pan. Therefore the unit ran for days and flooded our downstairs DEN. Oasis saved the day, reinstalling the switch and fixing the system. Now our old system is 19 years old and makes no sense to pay $1,000 to fix it so yesterday we decided to replace it.

Mike came out to look at the old central air and heating furnace unit which is in the upstairs of our bungalow. Seated horizontally, it was going to take a lot of work to get the old unit out and the new unit in. We selected the American Standard (highest rated in the industry a.k.a. Trane) 80K BTU 2 stage furnace/central air and an American Standard 3.5 ton 13 seer A/C unit outside. The team of 5 guys came out to install it just 4 days after signing the contract promptly at 7:00am and completed the entire job at 2:30pm. They had originally thought it would take a day and a half. I also elected the annual maintenance which they come out 2 times per year and will also cover labor, along with manufacturer's hardware warranty for 10 years.

The units are EXTREMELY quiet, you cannot even hear them run. Especially being outside and entertaining the patio. My electric bills are also expected to decrease significantly. The 19 year old previous system originally purchased from Sears was costing an additional $400/month just to run in the summer to to mention the old freon was $220.00 per pound.

I am VERY satisfied with Oasis HVAC, quality product, quality service, attention to detail, professional and courteous. They also don't change extra for after hours emergency maintenance and have been easy to reach in the time of need and arrive at the house in 1-2 hours after creating an appointment.

Oasis HVAC comes highly recommended from a highly satisfied customer.

Response from the owner:Thank you, Keith, for your wonderful feedback and for trusting Mike and our team at Oasis with your HVAC needs over the years; we're delighted to hear about your positive experiences and are thrilled that you're satisfied with your new system! We look forward to continuing to work with you!

Rick Rockwell

Our technician Chris was prepared and easy to work with, as we had two jobs for him. After an estimate, he worked us into his schedule for the next day. He was on time each day and very efficient in how he completed his work. These were both plumbing repairs.

Love Oasis. I use them for yearly maintenance. They’ve installed a new A/C unit and furnace in past couple of years and just had them put in a new water heater. Chris came out for the job.

Libby Snyder

I had the most wonderful experience with the team at Oasis Heating & Cooling. Today I had Damir, Amir, Anel, and Vaha out to replace a part in my unit. They were efficient, professional, kind, and completely fixed my issue.

I moved into my condo in April 2021 and my air conditioner has never worked correctly until now. I replaced the entire unit in 2021 with a company that is now out of business. Even that new unit did not work right. I finally did my research and found Oasis. I can’t stress enough how wonderful this company and specifically this team has been to work with. I will be calling Oasis for every future problem and will recommend them to everyone I know. Thank you Damir, Amir, Anel, and Vaha!

Response from the owner:Thank you, Libby, for your wonderful feedback! We're so glad to hear that Damir, Amir, Anel, and Vaha could resolve your issue and provide you with such a positive experience.
