Natural Gas Tankless Water Heaters in Chicago, IL

Are you tired of running out of hot water during your morning shower? Or maybe you’re looking for a more energy-efficient solution to your home’s hot water needs? Look no further than natural gas tankless water heaters from Oasis Plumbing, Heating & Cooling. Serving our customers in Chicago, Elmhurst, Bensenville, and Addison, IL for over 20 years, we have the expertise and knowledge to help you find the perfect tankless water heater for your home.

The Benefits of Natural Gas Tankless Water Heaters

Natural gas tankless water heaters offer a range of benefits over traditional tank-style water heaters, including:

Endless Hot Water: Tankless water heaters heat water on demand, so you’ll never run out of hot water again.
Energy Efficiency: Because tankless water heaters only heat water when you need it, they use less energy than traditional tank-style water heaters.
Space Savings: Tankless water heaters are small and compact, making them a great choice for homes with limited space.
Longer Lifespan: With proper maintenance, tankless water heaters can last up to 20 years or more, compared to 10-15 years for traditional tank-style water heaters.

Choosing the Right Tankless Water Heater for Your Home

When it comes to choosing a natural gas tankless water heater for your home, there are a few key factors to consider. At Oasis Plumbing, Heating & Cooling, our experienced technicians will work with you to determine the right size and model for your home based on your hot water needs and usage patterns.

One important factor to consider is the flow rate of the tankless water heater. The flow rate determines how much hot water the unit can deliver at one time, and is measured in gallons per minute (GPM). A higher flow rate means that the unit can supply more hot water simultaneously, which is important if you have multiple fixtures or appliances that use hot water at the same time.

Another factor to consider is the temperature rise of the tankless water heater. The temperature rise is the difference between the incoming cold water temperature and the desired hot water temperature. In Chicago, IL and the surrounding areas, where the incoming cold water temperature can be quite low, a higher temperature rise may be necessary to achieve the desired hot water temperature.

Professional Installation and Maintenance

Once you’ve chosen the right natural gas tankless water heater for your home, it’s important to have it professionally installed and maintained. At Oasis Plumbing, Heating & Cooling, our highly-trained technicians have the expertise and knowledge to ensure that your tankless water heater is installed correctly and safely.

We also offer regular maintenance services to keep your tankless water heater running efficiently and reliably. Our maintenance services include:

Flushing the Unit: Over time, mineral buildup can accumulate inside the tankless water heater, reducing its efficiency and performance. We recommend flushing the unit annually to remove any buildup and keep it running smoothly.
Checking the Burner Assembly: The burner assembly is a critical component of the tankless water heater, and should be inspected and cleaned regularly to ensure proper operation.
Testing the Pressure Relief Valve: The pressure relief valve is a safety device that prevents the tankless water heater from building up too much pressure. We recommend testing the valve annually to ensure that it is functioning properly.

Customer Reviews

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 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.

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.

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.

Joseph came, explained everything I could've needed to know, showed me pictures of the clog, cleaned it out, couldn't have been easier. This is the furnace they installed 10 years ago, we haven't had any issues in 10 years, and this would have been prevented of we got regular services! Happy to support this local company and they do great work. Summer '26 update. Fernando and Joel installed a new AC unit as ours was over 20 years old and started making lots of me noises. Reasonable price, quick service, the unit has been working great for a few months now.

Response from the owner:Thank you, John! We're glad to hear that Joseph provided you with such thorough service and that your furnace has been performing well for a decade. We appreciate your support of our local business and look forward to continuing to serve you!

The Oasis team is super responsive and their expertise in ductless/heat pump systems was critical. They remedied errors in our original installation (done by our former general contractor) and now our heat pump system is working great.

Oasis is very helpful and quickly responds to issues. I appreciate their fair and honest approach - they will tell us when problems are associated with systems that they install/repair and when they are not. I greatly appreciate the candor.

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!

Erin Dziubski

I gathered quotes from two other area HVAC companies for an a/c install. Feeling frustrated and let down with our uncertainty of how necessary this was, we saw an Oasis truck pull up beside us on our drive home. I looked them up and they had great reviews so we scheduled an appointment with them. Eb did the assessment and said he had been working with the company for over a decade, came and diagnosed our issue (same as the two others/best option for our old system was a replacement). He explained what was going on better than anyone else and answered all my questions. Install was done today! Thanks guys! Honest & dependable work!

Response from the owner:Thank you, Erin! We're glad you found us and had a positive experience with Eb's assessment and installation. Your feedback about our honest and dependable work means a lot to us!

Linda Y

The tech was on time, very polite and gave us the honest truth on our ancient AC unit. He seemed very knowledgeable and patient with all our questions. Scheduling was a breeze too over the weekend. Highly recommend

Response from the owner:Thank you, Linda! We're glad to hear that the technician was punctual, polite, and able to provide you with valuable insights about your AC unit. It's great to know that scheduling was easy for you as well. We appreciate your recommendation!

Tom Quintero

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.

Nick Ferguson

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!

Pedro Gomez

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.

Chun liu

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.

Philip Foxworthy

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!

Mary Montgomery

Very friendly and helpful arriving on time. Explained the problem with the AC unit and detailed the process for repair. They will send us an estimate, and we shall proceed from there. Thank you!

Response from the owner:Thank you, Mary! We're glad to hear that you found our team friendly and helpful. We appreciate your patience and look forward to getting your AC unit sorted out.

Joanna Donohue

I just had Oasis for HVAC maintenance. They are very professional, answer the phones, great office staff, on time, service man was knowledgeable & he had an assistant. They are reasonable priced. They service quick a few condo units in our building.

Response from the owner:Thank you, Joanna, for your kind words and for trusting us with your HVAC and plumbing needs; we appreciate your recommendation and are glad Chris provided you with prompt and exemplary service.

Lincoln Lamberton

Joseph, Anel and team did a great job with our HVAC system install. Professional, courteous and friendly. Would recommend!

Response from the owner:Thank you, Lincoln! We're glad to hear that Joseph, Anel, and the team provided you with a professional and friendly experience during your HVAC installation. We appreciate your recommendation!

Jack Peterson

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.

Response from the owner:Thank you, Jack! We're glad to hear that you had a great experience with our team, and we appreciate your kind words about Mike, Fernando, and Nayim. Your satisfaction means a lot to us!
