Customer Reviews

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.

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 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.

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.

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.

Magali Diaz

Our heating wasn’t working and Oasis was able to come over early the next day to fix it. It was a loose wire and a quick fix, so I’m grateful we didn’t have to wait days for an appointment like with other places we’ve contacted before. I really appreciate the friendliness of everyone on the Oasis team and the ease of communication! Thank you and will be calling you guys when needed :)

Autumn Riggenbach

Such a great experience! Learned about them through referrals in Lakeview. We closed on our apt on Tuesday. I was able to have someone come out on a Wednesday to check out the furnace and dehumidifier. The team was able to replace everything by Friday.

I was nervous about up charges with the cold weather just kicking off, but instead, Oasis gave me a discount and helped bring everything up to code (for free or extremely low costs).

Highly recommend! I will be purchasing their 2x a year services too. The guys were such gentlemen, on time and super clean.

Thank you!!

Response from the owner:Thank you, Autumn, for sharing your wonderful experience! We're glad our team could assist you so efficiently and provide the service you needed. Your recommendation and decision to continue with our services mean a lot to us!

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! Definitely use them!

Response from the owner:Thank you, Kristin, for your kind words and for being a loyal customer; we truly appreciate your support and are glad to hear about your positive experience with our team! We are here for all of your HVAC and Plumbing Needs!

Just the Best! Fernando & Michael quickly appeared and got us all set for the cold weather ahead. The two furnaces in our two-flat home were fully cleaned and inspected, new filters installed. All questions answered, no worries. Whew. Highly recommend.

Response from the owner:Thank you, Ellen! We're so glad Fernando and Michael could help get your home ready for the cold weather. We appreciate your recommendation and are here for any future needs!

Response from the owner:Thank you, Andrew, for your kind words about Joseph's exceptional service; we appreciate your feedback and are glad to hear you had a positive experience.

Martin Kehe

Oasis is an outstanding HVAC contractor. We've used them for over tenyears and they always offer quick, reliable service. We're on their monthly maintenance program for the two systems in our two-flat, and it's a great value. In addition, they recently replaced our furnace and thermostat with an updated model. The work was done at a reasonable price and very quickly, finished in about 3.5 hours. I highly recommend Oasis!

Response from the owner:Thank you, Martin, for your wonderful review! We're grateful for your continued trust in Oasis and are glad to hear you’re pleased with our service and the recent furnace upgrade. It's been a pleasure to work with you throughout the years!

Simon Meredith

Naem found the Nest thermostat problem and solved it very quickly…Thanks, Oasis!

Response from the owner:Thank you, Simon, for recognizing Naem's quick work in resolving the Nest thermostat issue! Your feedback means a lot to us.

mifune141

Chris was quick to contact me about my water heater and gathered all the details. He also gave me an estimate for a replacement heater and kept me up to date on the work. Everything turned out great and I’m very thankful for Chris’ help. Thank you!

Edit: Bathroom sink faucet replacement 10/16/2025. Chris came by as my old faucet was in bad shape. He explained everything thoroughly and the replacement went smoothly. Very grateful for your help Chris!

Response from the owner:Thank you for your kind words! We're so happy to hear Chris has continuously provided you with excellent service. Your appreciation means a lot to us!

Kelly Almousily

I have used Oasis for heating & cooling maintenance previously and this was my first time calling them for plumbing needs. As always, they were great with scheduling and communication. Shout-out to Chris! He was great to work with and efficiently fixed a couple issues happening with my kitchen, sink & disposal.

Response from the owner:Thank you, Kelly, for your kind words! We're glad to hear that Chris provided you with excellent service and that you had a positive experience with our scheduling and communication. We appreciate your support!

vandelisle

Our second time using Oasis and I could not be happier. GREAT service and reasonably priced. The technician, Joseph, was professional, friendly and very knowledgeable. As he was explaining, in detail, what he was doing, I was afraid there was something wrong. But no, everything was fine. He just feels it's best to let us know that he's checking everything. Good guy! So happy I found Oasis! HIGHLY RECOMMENDED!

Response from the owner:Thank you, Vandelisle, for your wonderful feedback! We're so glad to hear that you had a great experience with Joseph and appreciate your recommendation. Your satisfaction means a lot to us!

Pete Lauer

Amir and Damir showed up exactly at the appointment time. Oasis was very prompt with scheduling and reasonable with pricing for a burned out furnace inducer fan motor.

Response from the owner:Thank you, Pete, for your kind words and for recognizing Amir and Damir's punctuality, as well as our scheduling and pricing; we appreciate your feedback!

victor velasco

Did maintenance for 3 furnaces. They pointed out a few thing that needed attention. Didn't feel pressured to fix them. Overall friendly staff and good price.

Response from the owner:Thank you, Victor, for your feedback! We're glad to hear that you found our staff friendly and appreciated the pricing. Your comfort in the process is important to us, and we appreciate your trust in us to address your furnace maintenance needs.

Elizabeth Scarcello

Response from the owner:Thank you, Elizabeth, for your 5-star rating! We appreciate your support and are glad to have you with us.

Stephen Nicolls

I was very impressed by Oasis. I had to replace both my AC and furnace and they were excellent - quick turn around, friendly service and very respectful for my unit. They also accommodated an additional ask to reconfigure some of my duct work to free up some space. All in all I would happily recommend Oasis. The team that worked on my unit were Amir, Damir, Fernando and Michael.

I also had a leak in the Ptrap from the unit above which was separate to the replacement in my unit. Chris the plumber was excellent and did a very professional job. Highly recommended.

Response from the owner:Thank you, Stephen, for your kind words and for recommending Oasis; we’re glad Amir, Damir, Fernando, Michael, and Chris could provide you with excellent service and meet your HVAC and plumbing needs!

Don Lamers

Response from the owner:Thank you, Don, for your fantastic 5-star rating! We truly appreciate your support.

Aaron Mobarak

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.

Response from the owner:Thank you, Aaron! We appreciate your kind words and are glad Hani, Fernando, Damir, and Michael could provide you with a great experience. Your recommendation means a lot to us!

Justin Walsh

Got us back up and running the same day. Fast and professional service!

Oasis replaced my hot water heater for a good price and performed solid work in a really timely manner. I would use them again if I need any more work done !

Response from the owner:Thank you, Lucas, for your kind words! We're glad to hear you were satisfied with the hot water heater replacement and our team's timely work. We look forward to assisting you again in the future!

Stephanie Madden

I have used Oasis several times in the past for maintenance and finally just had my HVAC system replaced. With each Oasis experience, the techs have been kind, thorough, efficient, and knowledgeable. My system is located in my living room and the techs were so careful with removal of my old unit and installation of the new one. Not a mark or scratch in sight when they left. I can’t recommend them enough!

Response from the owner:Thank you, Stephanie, for your wonderful feedback! We're so glad to hear that our team provided you with a great experience during your HVAC replacement. Your recommendation means a lot to us!

Laurie M Marshall TCA

Professional, prompt, and personalized service. Completed replacing two furnaces w/humidifiers, air purifiers, and HEPA filters, thermostat, a/c unit, and repaired duct work as needed all in a timely manner. Properly documented work with photos. As importantly, outstanding communications by their office and field technicians - all under the outstanding leadership of the owner. BRAVO! We have now added them as our plumbing service and annual HVAC check up team!

Response from the owner:Thank you, Laurie, for your kind words and recognition of our team's efforts, including the leadership of our owner; we're glad to be your go-to for plumbing and HVAC services! We greatly appreciate your support and the opportunity to work with such a lovely person!

Dale Benjamin

Oasis service is always friendly, timely, and knowledgeable. I have worked with a number of the techs, including Danny, Hany, the owner, and even the receptionist are all so caring, considerate and helpful. I highly recommend this company for any of your heating and cooling needs.

Response from the owner:Thank you, Dale, for your wonderful feedback! We're glad to hear that our team, including Danny and Hani, provided you with such caring and knowledgeable service. Your recommendation means a lot to us, and we look forward to continuing to work with you!

Much more affordable and way better service than their competitors. I'm looking forward to continuing to work with them.

Response from the owner:Thank you, Andrew! We're so glad you find our service affordable and better than the competition. We appreciate your support and look forward to continuing to work with you as well!

P O

The technician was extremely unprofessional and incredibly rude. He got frustrated by how I might have misunderstood his poorly communicated instructions and started to take out his frustrations on me by throwing accusations in the middle of a service. He barged into the apartment and started to open random doors without my permission trying to find the water heater, despite that I was already there, showing him the way. He did not listen and kept yelling. Horrible and horrifying experience. I don’t know his name because he never said hello or introduced himself but he’s a white man with ginger hair. I’ve worked with many HVAC techs, electricians and plumbers for my job and he surely was THE worst in this country.

Anna Kozlowski

Oasis team is professional and great to do business with. They are on time.

Response from the owner:Thank you, Anna, for your kind words about the Oasis team; we appreciate your support and are glad to hear you had a great experience with us!

Katie Basil

Had a great experience working with Chris, the plumber from Oasis! My Navien tankless water heater stopped working, and Chris was able to repair the broken parts instead of needing to replace the entire unit, which other companies told me was the best option. He was professional, friendly and did an overall fantastic job. Oasis has also serviced my HVAC system for a few years and the employees are always fair, genuine and seem to be looking out for you :). Thanks for being so great guys!

Response from the owner:Thank you, Katie, for your wonderful feedback! We're so glad to hear Chris was able to help with your water heater and appreciate your kind words about our team and service over the years. Your support means a lot to us!

Trisha Woodson

The tech arrived promptly, checked out our systems and assured me we didn’t need $4,000 in repairs that another company told us we needed. Oasis you have our business now!

Response from the owner:Thank you, Trisha, for your wonderful feedback! We're glad to hear our tech was able to provide you with peace of mind and save you from unnecessary expenses. We look forward to serving you in the future!

Lydia Kulatti

Response from the owner:Thank you so much, Lydia, for your 5-star rating! We appreciate your support and are glad to have you with us.

Patrick Cuffaro

We had a very upsetting experience with Chris from Oasis. My elderly in-laws had their gas shut off by People’s Gas due to a house pipe leak in the basement. My wife and I drove in from the north suburbs to help them, since this was a stressful and unsafe situation.

When Chris arrived, instead of helping, he insisted nothing could be done until People’s Gas marked the lines which was not relevant since the leak was inside the house. While we were actively looking for the official paperwork from People’s Gas (which clearly stated that a contractor needed to pressure test the system at 3 PSI), Chris had no patience, was rude and yelling, and ultimately left before we could even show it to him.

My in-laws were left without answers, without a repair, and with a very unprofessional encounter. This was not the service we expected, and it was a waste of time in a situation where we needed clarity and help.

Austin Byers

Courteous, professional, communicative! It was easy to reschedule my appointment over text, and our technician, Amar, was friendly and helpful, answering my many questions

Response from the owner:Thank you, Austin! We're glad to hear that rescheduling was easy for you and that Amar provided friendly and helpful service. Your feedback means a lot to us!

Parag K Patel

I have been working with Oasis for over p12 years and continue to be amazed at their responsiveness, their professionalism, and the pride + ownership they take in their work - all the techs + the owner himself are great! Highly recommend them

Response from the owner:Thank you, Parag, for your kind words and continued support over the years; we truly appreciate your recommendation and are glad to hear about your positive experiences with our team!

Dirck Steimel

Stephen Garvey

Had an issue with an old ejector pump and Chris from Oasis came in and did an awesome job to quickly fit us with a replacement. Will definitely reach out to Oasis again for future plumbing, heating, and cooling needs.

Response from the owner:Thank you, Stephen, for your kind words and for recognizing Chris's efforts; we're glad we could help with your ejector pump and look forward to assisting you with your future plumbing, heating, and cooling needs!

Andrias Campbell

Response from the owner:Thank you, Andrias, for the fantastic 5-star rating! Your support means a lot to us.

Cap DeLaney

I have been doing business with Oasis Heating and Cooling for close to 20 years. Today they conducted a preventative maintenance service call on both my furnace and a/c units. Joseph and Amir were the 2 techs and they both were professional, knowledgeable, and provided efficient service during my hectic work day. Kudos to both of them and to Oasis for continuing to higher great talent.

Response from the owner:Thank you, Cap, for your long-standing support and for recognizing Joseph and Amir's professionalism; we truly appreciate your kind words and are glad to have you as part of the Oasis family.

Kelsey Swyter

Very happy with the service when my AC stopped working. Originally Oasis could not do a consultation on the weekend and they put me on a waitlist. Fortunately they contacted me later that day and scheduled me for the weekend. I ended up having to replace my system and they gave me a fair price with an end of season discount. The workers were on time a couple days later, replaced the system quickly and even installed my smart thermostat at no extra charge. Would use Oasis again in a heartbeat!

Response from the owner:Thank you, Kelsey! We're so glad to hear that you had a great experience with our team and that we could assist you quickly. Your satisfaction means a lot to us, and we appreciate your kind words about our service and pricing. Looking forward to helping you again in the future!

Cynthia Chernoff

Update for 2025:
Oasis comes through again. I recently learned that Oasis now offers duct and vent cleaning, so when our dryer stopped drying, I knew just who to call. A phone call Monday got me service Thursday morning. As before, the team was prompt, professional, and effective.

Oasis Heating and Cooling have been so helpful to us. A couple of years ago they replaced our heater during a cold snap, and now they have saved us from the heatwave. Our AC went out Saturday afternoon, and they responded to my service request within an hour and had a tech out Sunday morning. Naem assessed the problem, recommended a new unit (ours was more than 15 years old), and installed a temporary replacement part to carry us through until the installation crew could replace the unit on Wednesday. That crew was prompt, polite, and knowledgeable. Though the installation took twice the time estimated because they had to rebuild some of the exhaust chimney, the final price was as in the estimate—no extra charges for labor time. Strongly recommend!

Response from the owner:Thank you, Cynthia, for your wonderful review! We're delighted to hear that our team was prompt and professional, and we're so happy to continue working with you! Your support and recommendation mean a lot to us!

Bobby Sutton

Very easy to work with and honest about expectations

Response from the owner:Thank you, Bobby, for your kind words; we appreciate your feedback and are glad to hear you found us easy to work with!

Ankit Vadher

Prompt, knowledgeable, patient and thoroughly explains what was done, what the condition is, and guidance for specific issues/concerns, highly recommend.

Response from the owner:Thank you, Ankit, for your wonderful feedback; it's great to know you found the service prompt and informative!
