AC Replacement in Hillside, IL: Upgrade Your Comfort with Oasis Plumbing, Heating & Cooling

When the summer heat strikes in Hillside, IL, a reliable and efficient air conditioning system is essential for your comfort. If your AC unit is struggling to keep up with the rising temperatures or has reached the end of its lifespan, it may be time to consider an AC replacement. At Oasis Plumbing, Heating & Cooling, we specialize in providing top-quality AC replacement services to homeowners and businesses throughout Hillside and the surrounding areas.

Signs You Need an AC Replacement

Before you make the decision to replace your air conditioning system, it’s important to recognize the signs that indicate it’s time for an upgrade. Here are some common indicators that your AC unit may need to be replaced:

  • Age: Most AC units have a lifespan of 10-15 years. If your system is approaching or has surpassed this age, it may be time to consider a replacement.
  • Frequent Repairs: If you find yourself constantly calling for repairs on your AC unit, it may be more cost-effective to invest in a new system rather than continuing to pay for frequent fixes.
  • Increased Energy Bills: An aging or inefficient AC unit can lead to higher energy consumption and, consequently, higher utility bills. Upgrading to a new, energy-efficient system can help you save money on your monthly expenses.
  • Uneven Cooling: If you notice that some rooms in your home are consistently warmer or cooler than others, it may be a sign that your AC unit is struggling to distribute air evenly throughout your space.
  • Strange Noises: Unusual sounds coming from your AC unit, such as grinding, squealing, or rattling, can indicate serious problems that may require a replacement.

At Oasis Plumbing, Heating & Cooling, we have been serving our customers in Chicago and the Northern Suburbs for over 20 years! Our experienced technicians can assess your current AC system and provide expert recommendations on whether a replacement is necessary.

Benefits of AC Replacement

Investing in a new air conditioning system offers numerous benefits for your home or business in Hillside, IL. Some of the key advantages include:

  1. Improved Comfort: A new AC unit will provide more consistent and effective cooling, ensuring that your space remains comfortable even during the hottest days of summer.
  2. Enhanced Energy Efficiency: Modern AC systems are designed with energy efficiency in mind, which means they consume less power while delivering better performance. This can lead to significant savings on your energy bills over time.
  3. Increased Reliability: With a new AC unit, you can enjoy the peace of mind that comes with knowing your system is less likely to break down or require frequent repairs.
  4. Better Indoor Air Quality: Newer AC units often feature advanced filtration systems that can help remove allergens, pollutants, and other contaminants from your indoor air, promoting a healthier living environment.

Customer Reviews

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.

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 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.

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 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 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.

Called to fix a common evaporator drain issue. The tech seemed to do an adequate job however the water from the evaporator continued to drain inside my house. Called again, another tech came and he said I was good to go. Still I had water leaking in my house. Called another company and this time the tech did a fantastic job. Actually fixed the problem! Guess which company I’m using to replace my entire system?
Response from the owner:Hi Tom, we’ve searched our records but haven't been able to match your review to a customer in our system. We take feedback seriously and would love the opportunity to learn more about your experience and see how we can make things right. Please give our office a call directly at (773) 320-5395 at your earliest convenience.

Master plumber Steve was extremely knowledgeable, skilled and friendly. He went the extra mile on my service call to troubleshoot and make sure my new shower trim handle was installed. He left the place looking better than before and explained everything to me in detail so I could understand my shower plumbing better. I also had a good experience talking with the support team and GM Josh.
Response from the owner:Thank you, Nick! We appreciate your kind words about Steve's expertise and the extra effort he put in during your service call. We're glad to hear you had a positive experience with the support team and Josh as well. Your satisfaction means a lot to us!

Not the best estimate, pricy for one stage AC installation, the guy who came is nice but still charged for 120$ supposedly for tune up or cleaning but what happened is installation estimate which is just free for other companies.
Response from the owner:Hi Pedro, our team left you a voicemail earlier regarding your service. Since the maintenance was not performed, a full refund is being processed for you. Thank you for letting us know so we could get this corrected.

Great service. No hustle. Signed up for the regular service.
Response from the owner:Thank you, Chun! We're glad to hear you had a great experience with our service and appreciate your decision to sign up for the regular service.
Oasis was really professional and friendly. They came by for maintenance on our AC units and immediately realized we were low on coolant. They topped us up and didn’t charge for the full amount they used. And their member program is a great deal. You get a discount on maintenance by signing up for reminders, no annual or monthly fee. You get a benefit for something you should probably have anyway, reminders for annual servicing. Will definitely use again!
Response from the owner:Thank you, Philip! We appreciate your kind words about our professionalism and friendliness. It’s great to hear that you found value in our member program and enjoyed the service. We look forward to assisting you again!

Oasis installed a new furnace and AC for us, and were great throughout the process. Mike came out same-day to do an inspection and give us an estimate, and Fernando and Nayim came out the next day and did the install in a very efficient manner, talking us through the process as they went. We are very satisfied with the level of service they provided.
