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 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.

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.

Josh D.

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 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 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.

This is a highly trusted business. I've worked with them for the past 10 years and they are absolutely, hands down one of the best customer focused businesses I've come across. I had an issue with my A/C recently (during one of those 90+ degree nights) and called to leave a message for the morning.......the owner of the business Mike Causevich answered my call and walked me thru what to do to fix my system without them having to come out. I give them my highest recommendation.

Response from the owner:Thank you, Sharon, for your kind words and continued trust over the past decade; we're glad Mike could assist you during that A/C issue, and we appreciate your highest recommendation!

Jacqueline Davila Benson

Knowledgeable, friendly and on time. Would definitely recommend.

Rina Patel

(July ‘26) Reached out as my AC went out. Was ghosted by Craig. Understand it was a holiday weekend. But no followup even the next week. Very disappointing. (January ‘26) The nicest man came out at 7am to check out my system. And then another super nice person came out at 12:30pm, part in hand to fix my system, saving me from having to replace my furnace. Both people were kind, professional, and worked quickly. I’ll be using them again, for sure!

Response from the owner:Thank you, Rina! We appreciate your kind words about our team and are glad we could assist you promptly. We're looking forward to helping you again in the future!
