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.

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.

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 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.

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.

JKG

The owner bid the job (A/C and furnace replacement). Very good pricing and warranties. Damir, Amir and Harvey performed their work with skill, efficiency and were respectful of the work space and quite pleasant individuals. Highly recommend this company.

Mark Tomlinson

We have a high end furnace and A/C. Needed service from somebody accredited with American Standard. They were easy to work with and schedule. They did a thorough job on regular maintenance and were appropriately priced.

Jodi Slaght

Oasis installed our water heater and was very helpful in explaining what was wrong with the old water heater and how to maintain the new one. They were also very responsive when we encountered an issue and were able to fix the issue. We also appreciate their proactive approach to notifying us of a possible issue with our A/C. I really appreciate their professionalism and responsiveness and fair pricing!

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!

Y. “Dewey” Du

I recently hired Oasis to replace three AC units and a furnace. I have to say that the entire process went very smoothly. From job quoting to signing the contract, to office communication scheduling the job dates, then to getting the systems installed, Oasis team is very organized and efficient. On the days of the job (took two days since multiple systems were being replaced), the installation crew, Fernando and Michael (there was another gentleman on the second day, sorry, I didn’t get his name) showed up on time, removed the old and installed the new systems seamlessly. They were very friendly, patiently answered all my questions, and cleaned everything after the job was done.

One extra note I want to add is that during the quoting process, I mentioned a small pipe leaking problem with one of the water heaters in the property. The owner Mike agreed to fix this small issue free of charge (thanks, Mike). The office sent a plumbing technician out on a separate day to get it fixed. This gentleman was also very friendly, professional, and got the job done neatly. Overall, Oasis definitely made me feel that they are the kind of company who stands behind their work, who I can trust when there is a HVAC or plumbing need.

Response from the owner:Thank you, Dewey, for taking the time to leave such a wonderful review and for recognizing our team's efforts, from your techs to our office staff! We truly appreciate your trust in us for your HVAC and plumbing needs. Please don't hesitate to reach out for all your needs in the future, no matter how big or small!

Ahmet Patel

Amazing guys amazing work

Response from the owner:Thank you, Ahmet, for your kind words; we truly appreciate your support and are glad you enjoyed our work!

K C

Called about replacing entire hvac system, was able to get a quote immediately over the phone with just pictures of our current system, being spring before and after the busy season the quote was very fair and what I was expecting, in line with the previous replacements I’ve done on other properties. Scheduled service for when was convenient for us and worked for them. In at 8am and complete by 2pm.
New unit tested out much more efficient than the much older previous system and no surprises in cost or services not quoted.
Damir, Harvee and Amir were all very friendly, professional, respectful and informational.
Being the person my friends all come to for home improvement and contractor advice (real estate side gig for 25+ years) I will whole heartedly recommend this team and Oasis.

Response from the owner:Thank you, K C, for your wonderful feedback! We're glad to hear that you found our quoting process efficient and that Damir, Harvee, and Amir provided you with excellent service. We truly appreciate your recommendation and look forward to assisting you again in the future for all of your HVAC and Plumbing needs!

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

Bart Msimangira

Damir and Amir came in to replace our old furnace. They arrived on time, they were professional and super friendly. The father and son duo managed to replace our furnace in 6 hours which was shorter than I expected. Amazing guys, amazing service, I highly recommend Oasis heating to anyone looking for quality heating services. Thank you!

Response from the owner:Thank you, Bart, for your kind words and for recognizing Damir and Amir's hard work; we're glad to hear you had a great experience with us! Your recommendation really does mean a lot to us!

Oasis is a good (i believe) family owned business. The employees are polite and well trained. I received an excellent price for my AC unit. And the installation was seamless. I would recommend them to those who are interested

THE BEST EXPERIENCE in my 68 years with a home repair. Replaced my central AC.

Ken Guttentag

We have been customers of Oasis for many years now, starting with an emergency furnace replacement and since then for all needed service and repairs for heating and air conditioning. Oasis is the best service provider we've used. Always prompt, courteous, very reasonably priced. When we had on ongoing issue they came out several times until it was resolved with no service call charges. I trust Mike and Oasis completely to get the job done well, timely and at a fair cost, and knowing that they truly stand behind their work.

Response from the owner:Thank you, Ken, for your kind words and for being a loyal customer over the years; we're glad to hear that Mike and the team have consistently met your expectations and provided you with reliable service. We truly appreciate your continued trust and recommendation!

Sharon OBrien

This is a highly trusted business. I've worked with them for the past 10 years and they are absolutely, hands down one of the best customer focused businesses I've come across.

I had an issue with my A/C recently (during one of those 90+ degree nights) and called to leave a message for the morning.......the owner of the business Mike Causevich answered my call and walked me thru what to do to fix my system without them having to come out.

I give them my highest recommendation.

Response from the owner:Thank you, Sharon, for your kind words and continued trust over the past decade; we're glad Mike could assist you during that A/C issue, and we appreciate your highest recommendation!

Patrick McEneely

Oasis came out and serviced my furnace in an emergency situation and handled the issues with the utmost professionalism. I have worked with many companies and tradesman over the years and Oasis is different, they are prompt, courteous, professional and extremely knowledgeable about what they do. They are honest too and fair in their leaving. This is the best HVAC company in Chicago in my opinion.

Response from the owner:Thank you, Patrick, for your kind words and for trusting Oasis with your emergency furnace service! We truly appreciate your recognition of our team’s professionalism and knowledge. Thank you so much for your support and recommendation!

Rebecca Brokmeier

Great service, resolution and timely!

Response from the owner:Thank you, Rebecca! We appreciate your kind words about our service and are glad we could resolve your issue promptly. We appreciate your trust in us!

Dru Shockley

Oasis did a stellar job. Always nerve-wracking when a furnace goes out, especially in winter. They gave me a fair price, came out immediately, and performed a great installation. Also very courteous and professional. They've locked in my business as my multi-flat has other aging units. I just hope to space it out significantly. Thanks, Oasis!

Response from the owner:Thank you, Dru, for your wonderful feedback! We're glad to hear you had a positive experience with our team and appreciate your trust in us for your future needs. We're here whenever you're ready for your next project!

José Luis López

Response from the owner:Thank you, José, for your amazing 5-star rating; your support means a lot to us!

John MacInerney

I called Oasis last Saturday morning, due to a noisy, rattling furnace. The owner, Mike took my call, and came to my house in about 25 minutes. He knew right away that a fan’s bearings required the fan to be replaced. He picked up the replacement fan that morning and had a very competent technician, Jason, replace the fan on Monday. I highly recommend Oasis- the whole transaction was seamless.

Response from the owner:Thank you, John, for your fantastic feedback! We're glad Mike was able to assist you quickly and that Jason provided you with great service. We truly appreciate your recommendation!

I had a great experience with Oasis. Mike arrived within two hours of my service request, diagnosed the issue quickly, and had it fixed in no time. What stood out was his willingness to explain the problem and how to prevent it in the future, along with offering helpful insights about my furnace and HVAC system. No upselling, just straightforward and knowledgeable service. Would definitely recommend.

Response from the owner:Thank you, Aaron, for your wonderful feedback! We're glad Mike could provide you with prompt and informative service. Your recommendation means a lot to us!

Chris was great! Very professional and attentive. He walked us through exactly what was going on with our hot water tank and was able to exchange it for a new tank. There is no doubt we will continue to use Chris and Oasis in the future!

Devon Freeny

The twenty-year-old furnace in my condo finally died just before the last big cold snap. On a recommendation from a friend, I called Oasis and they were able to replace the entire system within twenty-four hours. Technicians Damir, Amir, Amar, and Harvey were not only fast but also courteous and careful, leaving no debris or anything out of place and the system working perfectly.

Response from the owner:Thank you, Devon, for your wonderful review! We're glad to hear that our team, including Damir, Amir, Amar, and Harvey, provided you with excellent service. Your satisfaction is our priority, and we're here if you need anything else!

Judith Piccione

We had Oasis come to our house to service and evaluate our 3 furnaces. They are 30 year old Lennox brand. They found them to be in perfect working order and didn’t try to upsell us. I also asked for the replacement cost when the time comes. Their prices are very reasonable and the technician was very knowledgable and profession and polite. I highly recommend because you can trust them to tell you the truth and give an honest opinion and pricing.

Response from the owner:Thank you, Judith, for your kind words and for trusting us with your furnaces; we're glad to hear our technician provided you with honest service and valuable information. We hope to see you again soon!
