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 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 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.

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.

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.

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.

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 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.

Had Joseph out to take a look and he was extremely thorough and knowledgeable. My AC unit is harder to access since it’s in a tighter spot and he was able to take apart a small piece of it to see the model #. He was very efficient and super helpful and provided solutions. I will definitely be using them again.
Response from the owner:Thank you, Erin! We're glad to hear that Danny provided you with kind and efficient service. We appreciate your support and look forward to assisting you with your next HVAC service!

Had my condenser replaced. After an initial Friday call diagnosed the problem, I made a Monday appointment for installing the new condenser. Later Friday, they called and had a Sunday morning opening. I took that. Two technicians came on time and did the install in a bit less than four hours (I was told on Friday it could take four to six hours). The two technicians were courteous and professional.
Response from the owner:Thank you, Mike, for your fantastic review! We're glad to hear that the technicians provided timely and professional service during your condenser installation. Your satisfaction is important to us, and we appreciate your trust in our team.
I live in a 3 story townhouse in River North, with an arguably terrible HVAC design. It's a horizontal unit on the first floor above the powder room.  Great for saving space, but terrible for maintenance and even worse for a replacement.  The unit was 21 years old, so ready for a rehaul.  We had somewhat of an emergent need, as the drains were clogged and leaking pretty badly, and upon further inspection, black mold had grown all around the humidifier and drain pan.  We did our due dilligence and vetted 4 different companies, but after speaking with specialist Danny, we learned that Oasis was the team cut out for the job!  (Kudos to him for taking our call on a Saturday when he was in the middle of family time — that is dedication to his job!)  He explained his rationale behind his recommendations (e.g. 2.5T model vs 3.5T model), which were different than what currently existed and what the other companies quoted, and I am so glad we listened to his expertise.  The unit cools the house so much more efficiently, it is quieter than before, and we have a more balanced climate throughout all 3 floors. The installation was especially difficult because of its location, but the team led by Serge did a phenomenal job.  I was worried they'd have to cut the ceiling and give me another headache to worry about, but they spent a total of 4 days to make the necessary accommodations to ensure the install was safe and done correctly.  I sincerely appreciated that they didn't upcharge me for the difficult installation and multiple days of work; it shows me they stand behind their promise and want to deliver an excellent service.  It was well orchestrated between the dispatch team and the techs, because we had multiple things to check and correct between the leaking/clogged pipe and the HVAC system. The owner Mike even came 2 of the days to oversee his team and help them do their job more efficiently.  That says a LOT when you have an owner who rolls up his sleeves to help his guys. Replacing the furnace, AC, humidifier, and thermostat is a BIG investment of both time and money, and you want to feel confident you are picking the right provider.  You will be very happy with Oasis.
Response from the owner:Thank you, Vasiliki, for your detailed and wonderful review! We're glad to hear that Danny's expertise and the hard work of Serge and the team made such a positive impact on your HVAC system. It's great to know that you felt supported throughout the process and that the installation met your expectations. We truly appreciate your recommendation and are here for any future needs!
