Benefits of Tankless Water Heaters

Tankless water heaters offer numerous advantages over traditional storage tank models. By heating water on demand, they provide an endless supply of hot water while saving energy and space. Some key benefits of tankless water heaters include:

  • Energy Efficiency: Tankless water heaters only heat water when needed, reducing standby energy loss and lowering your utility bills by up to 40%.
  • Space Savings: Compact and wall-mounted, tankless water heaters free up valuable floor space in your home or business.
  • Longer Lifespan: With proper maintenance, tankless water heaters can last up to 20 years, twice as long as traditional storage tank models.
  • Instant Hot Water: Say goodbye to waiting for the tank to refill. Tankless water heaters deliver hot water on demand, whenever you need it.

At Oasis Plumbing, Heating & Cooling, our experienced technicians will help you select the right tankless water heater for your specific needs, taking into account factors such as household size, water usage patterns, and local climate conditions.

Customer Reviews

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 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.

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.

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.

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.

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.

Fantastic promp professional thorough and what more possibly could I say. I love this company and my service guy Chris was the best! I’ve written this before when he did a different job and it’s still my review on this one!
Response from the owner:Thank you, Sally, for your feedback! We appreciate your support and look forward to serving you again.
Excellent Service – Highly Recommend Hani! Hani from Oasis came out to perform maintenance on my furnace, and I can honestly say he was one of the best HVAC technicians I've ever dealt with. His knowledge, professionalism, and attention to detail were outstanding! For over four years, I've been dealing with an unusual smell coming from my HVAC system whenever the heat or AC was running. Several technicians have looked at it over the years, but no one could give me a clear explanation of what might be causing it. Hani was the first technician to take the time to thoroughly explain the potential causes, walk me through the system, and discuss possible solutions. His depth of knowledge was impressive, and he explained everything in a way that was easy to understand. After four years of unanswered questions, I finally have a much better understanding of the issue, thanks to Hani. His professionalism and customer service were truly exceptional. I can't recommend Hani highly enough!** I'll definitely be using Oasis again, and I'll specifically be requesting Hani for any future HVAC service. An excellent technician and an outstanding experience from start to finish!
Response from the owner:Thank you, Garfield! We're so glad to hear about your positive experience with Oasis and Mark. His thoroughness and professionalism truly make a difference. We appreciate your high recommendation and are excited to continue providing you with excellent service!

Vaha and Anel installed my new HVAC system THIS MORNING! It took them less than 4 hours. They were quiet, efficient and effective. They treated my dog, my Mom and I with the utmost respect. Upon completion they walked me through the furnace, the condenser and my programmable thermostat. Mike got back to me right away and we were scheduled within 48 hours. Joseph was on time and thoroughly explained everything. He also explained Oasis offers extended warranty simply by scheduling tegular service checks. Dan came to check our furnace out. He was prompt and quick. He gave me a couple reminders and was even kind to our dog!
Response from the owner:Thank you, Rachel! We appreciate your kind words about Vaha, Anel, and Mike. It's great to hear that you had a positive experience with the installation and that they took the time to walk you through everything. Your satisfaction means a lot to us!

**Great Service – Highly Recommend!** I had a great experience with Oasis Plumbing, Heating and Cooling. They recently serviced my heating system, humidifier, and radiant floor heating system. Joe and Damir arrived on time and were both professional, efficient, and very knowledgeable. They were thorough in their work and took the time to make sure everything was working properly. I also want to recognize Steve, one of their plumbers, who took the time to speak with me about a question I had regarding my radiant floor heating system. What impressed me most was that after our initial conversation, he gave it some additional thought and actually called me back with another idea about what might be happening. I really appreciated his initiative and follow-through. Overall, I was very pleased with the quality of their service and the level of care they demonstrated. I would definitely recommend Oasis!
Response from the owner:Thank you, Marcia! We truly appreciate your kind words and are glad to hear about your positive experience with Joe, Damir, and Steve. It’s wonderful to know that their professionalism and dedication made a difference for you. Your recommendation means a lot to us!

Oasis is a first class HVAC company. Oasis installed a new MagicPak unit for my condo in River North 1 year ago. Oasis completed the 1 year service as well. All of the services that Oasis provided were excellent. This includes system knowledge, system installation, office notifications for progress updates, check-ins for satisfaction responsiveness and price. If you need a new system, system repair or annual system service Oasis is your best choice!

I have been an Oasis customer (and fan) for over 20 years! I have only experienced the BEST service and professional care for all these years - their staff is excellent (and everyone has been there a long time so my experts keep coming back year after year). I feel known by their staff which gives me great peace of mind when they arrive to do a job…I know it will be done correctly, thoroughly, quickly, promptly and efficiently - and with a warmth and kindness that leaves me smiling. The consistency is so appreciated. I would never use anyone else!
Response from the owner:Thank you, Arlene, for being such a loyal customer for over 20 years and for your kind words about our staff and service; we truly appreciate your trust and support!
