Oasis Plumbing, Heating & Cooling

We hit furnace trouble on one of the coldest days of the year, and Oasis still got us in the same day—on-site within two hours of my call. Naem was our technician and was fantastic: kind, quick to diagnose, and had the heat running again in under 30 minutes. They also installed our rooftop A/C and did an excellent job. We’re really grateful for the whole Oasis team and their great service. Highly recommend them to anyone in Chicagoland.

“I know I can always count on Oasis when I have a problem.”

I know I can always count on Oasis when I have a problem! Joseph came out and was helpful and efficient fixing our furnace, which is more important than ever during the dead of winter! He even helped fix a closet door that helps keep the furnace shielded from my kids. Really grateful to Joseph and the entire Oasis team for another successful visit!

“Our heat went out mid winter.”

Our heat went out mid winter. Oasis sent someone out to diagnose the problem and replace the furnace the very next day. Everyone from their team was super kind and helpful. Fernando and Joseph did the install. They were fast, friendly, and explained everything to me to make sure I knew what was going on.

“Great experience with Oasis.”

Great experience with Oasis. When my furnace stopped working they were able to have someone (Danny) come out the next day. Danny explained everything very well and gave me estimates to replace the broken inducer motor and to to replace the whole furnace. I appreciated that he wasn't pushy in any direction but gave me his honest take. I had initially decided to replace the whole system, but then changed my mind and decided just to replace the part. When I called the office and asked if it was okay to change the plan, Chris was very understanding of my situation and I did not get a hard time about it. I really appreciated that. Joseph came out the next day to replace the motor, and like Danny did a great job of explaining things and seemed very honest. Overall every interaction I had with Oasis personnel was very positive and I felt like I was getting honest expertise. They were all very kind as well.

“Tech and installation members were friendly, knowledgeable, and efficient.”

Tech and installation members were friendly, knowledgeable, and efficient. The company is extremely easy to reach / provides fair pricing. Our heat went out on 12/30 and someone was out here the next morning on New Years Eve to check it out. Highly recommend for maintenance and repairs!

“Damir, Mark, Joseph, Vaha & Anel installed our new HVAC system and we’re all so profesional and polite.”

Damir, Mark, Joseph, Vaha & Anel installed our new HVAC system and we’re all so profesional and polite! It was a big job and it got done really quickly and felt like they were barely here. We also had duct cleaning which was very though, and Chris did some plumbing and did a fantastic job. Really blown away by the whole company including Marc the owner who did our quote for the whole thing. Will use for all my hvac needs going forward

“we have been using Oasis for more than 10 years.”

we have been using Oasis for more than 10 years. they replaced our furnace and AC unit through those years. we have never had any problem with heating or cooling since then. Oasis technicians and managers are courteous and knowledgeable. like today, Joseph, spent extra time to show us how our furnace works and the internal safety features that it has. we really appreciate that!

“Oasis was the quickest to be able to get to us when our heat went out at 9 pm on the coldest day of the year.”

Oasis was the quickest to be able to get to us when our heat went out at 9 pm on the coldest day of the year. Fernando and Michael were out the next day with a new unit and went above and beyond! When noticing how bad the a/c unit was with corrosion and mold they were able to replace that as well, timely, and all for a fair price! They were on time, professional, quick, and skillful-thank you!

“Oasis always delivers.”

Oasis always delivers! After doing repair work on our AC last year - because the company that did the install wouldn’t return our calls for service - we knew they were the right call for our furnace! Our furnace motor went out a few days ago - during the winter/a week before Christmas! What a nightmare. Oasis was able to come out first thing the next morning without charging us for an emergency call! Naheem was our repair tech and within 15 minutes he diagnosed the problem and gave us a couple of options with cost estimates. He provided his professional opinion and it felt genuine and unlike a sales pitch! 2 days later, Serge and Harvey came to replace our furnace! They were incredibly kind, respectful and efficient - arriving on time and finishing within the estimated time window. At the end, they did a walkthrough of the new furnace, answered questions about the filters, and even took time to re-affix and correct the settings on our Nest thermostat (that we fully messed up before calling them). So grateful to find service we can trust!

“This is my third experience having Oasis help with our HVAC and they continue to deliver great results.”

This is my third experience having Oasis help with our HVAC and they continue to deliver great results. Michael and Joseph went above and beyond to work on our system. The were super knowledgeable and helpful, and great at communicating and troubleshooting to get our system and keep it in tip-top shape! We also signed up for their annual maintenance program and that will continue to keep our HVAC running smoothly.
