High energy bills: An old or inefficient air conditioner can lead to increased energy consumption and higher utility bills.
Uneven cooling: If some rooms in your home are too hot while others are too cold, your AC may be struggling to distribute air evenly.
Strange noises: Unusual sounds coming from your air conditioner, such as grinding, squealing, or rattling, can indicate serious issues.

Improved comfort: A new AC unit will provide more consistent and effective cooling throughout your home.
Energy savings: Modern air conditioners are designed to be more energy-efficient, helping you save money on your utility bills.
Enhanced air quality: New AC units often feature advanced filtration systems that can help remove allergens, dust, and other pollutants from your indoor air.

Customer Reviews

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.

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.

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.

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.

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!

Update on May 2026: Oasis has a great plumbing team now! Thanks Steve and Amer for the smooth water switch change. They are very knowledgeable and patient. Update on April 2026: had my second appointment with Joseph, who was absolutely amazing. I can always learn something useful from him to better care for my system. Highly recommend him and Oasis! Glad I found Oasis to help me maintain my home heating and cooling system! From booking the first visit, to communicating the arrival time, Chris went up and above. My technician Joseph showed up on time and answered all my questions regarding my home furnace and humidifier. Will be working with them annually moving forward!

Response from the owner:Thank you, George! We're grateful you chose Oasis for your home heating and cooling needs. It's great to hear Chris and Joseph provided such excellent service, and we look forward to working with you annually!

Karen Otto

Oasis arrived on time to dismantle my 16 year old AC and carried the new AC up 4 flights in a tight staircase, all professionally done. The installation was completed in 4 hours and the result vastly improved not just the coolness of our home but the noise factor, it is unbelievable how much quieter with the new system. This is my 2nd experience with Oasis and I highly recommend and trust their team.

Response from the owner:Thank you, Karen, for your wonderful feedback! We're glad to hear that our team was able to provide you with a smooth installation experience and that you're enjoying the improved comfort and quiet of your new AC. We appreciate your trust and loyalty to Oasis!

Oasis is the best heating and cooling company to work with in all of Chicagoland! I will only work with these guys. They are professional, kind and considerate, and truly understand heating and cooling.

Response from the owner:Thank you so much! We know every HOA is different, and we are glad we could get the paperwork figured out so quickly. Thank you so much, and we hope to work with you again this winter!

Evan Westerfield

I have been using Oasis for several years. They installed my Space Pak a/c system, as well as (later) a new hot water heater. They service my boiler and the Space Pak and the hot water heater, on a regular basis. Communication is always excellent. Technicians are knowledgeable and friendly. And those few times when I've had an emergency, they've been there quickly (and times where I've had concerns, only to determine that it was my stupidity, they haven't charged me for the visits). Really pleased with the service!

Response from the owner:Thank you, Evan! We truly appreciate your loyalty and are glad to hear you’re satisfied with our communication and service. It's great to know our team has been there for you during emergencies. Your kind words motivate us to keep delivering excellent service!

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!
