Many Austin homes come equipped with traditional, tanked water heaters. These systems hold hot water at the ready, using utilities to keep it hot until you need it. The bulky tanks take up a lot of space and can be susceptible to rust and leaks. There has to be a better way.
There is! With a tankless water heater from Altruistic AC, Heating & Plumbing, you can enjoy dependable hot water without limits.
Unlike traditional methods, tankless water heater technology doesn’t rely on a supply of water on standby. These systems utilize a series of coils that heat water as it runs through the unit. This means the unit only heats water when a hot water tap is turned on. No more storing gallons of hot water on the off-chance it’s needed.
Tankless water heaters also have no limit to the amount of hot water they can deliver. Depending on the model, a tanked water heater can hold 20-80 gallons of water. Once that hot water is emptied from the tank, the system has to fill the tank and heat a new batch of water.
Not with a tankless system. Imagine it: hot water on demand, day after day.
When deciding between a tanked water heater and a tankless model, it’s essential to consider factors like energy efficiency, space utilization and continuous hot water supply.
Traditional tanked heaters store and heat a large volume of water, maintaining a steady reservoir for immediate use. However, they constantly have to heat to keep the tank warm — this uses a lot of energy!
On the other hand, tankless models heat water on demand. Water is only heated when you turn the tap or shower head on. This reduces the energy required and can have significant effects on the availability of hot water in your home. The small, compact design of the unit also helps save space in your home. The choice depends on your household’s hot water needs, available space and preference for energy-efficient solutions.
Consult with Altruistic AC, Heating & Plumbing to explore the best option for your home.
A tankless water heater is a long-term investment that offers an impressive lifespan — typically lasting over 20 years with proper care. However, even the best units will eventually require replacement. If you’re noticing decreased efficiency, frequent repairs or an inconsistent hot water supply, it may be time to consider upgrading your unit.
At Altruistic AC, we specialize in replacing old or failing tankless systems with modern, energy-efficient models that provide reliable hot water on demand.

The initial investment in a tankless system can be outweighed by long-term energy savings and the convenience of never running out of hot water. At Altruistic AC, Heating & Plumbing, we understand the dynamics of these systems and can guide you in making a decision that aligns with your household’s needs.
EXCELLENT Based on 801 reviews Posted on Google Robert LuthiTrustindex verifies that the original source of the review is Google. My air conditioning system failed on Sunday and was pretty sure it was the start up capacitor. Before searching for reputable HVAC companies to repair it, I reached out to TruTec Electric, who fixed a furnace disconnect in January, that wasn't installed properly by the original builder. They did an amazing job. They immediately referred me to Altruistic AC, Heating and Plumbing. This HVAC company went above and beyond. Juan Perez was very kind, informative and totally thorough. He changed out the capacitor and did an entire systems check inside and outside. He cares about his own level of quality and it showed. This is my new HVAC and plumbing company! June 2026 update. I had these guys change out my hose faucets outside. Perfect work. I told Cabe, my tech, that I wanted a quote to change out all three toilets in my home. He made that happen and told me to buy Kohler from the new Home Depot in Manor. I ordered them on a Friday evening, they were delivered at 7am the next morning. Scheduled installation and Cabe came back on Monday and installed three toilets and did an amazing job. He even took my old one's away. Extremely impressed with this company!Posted on Google Lillian WrightTrustindex verifies that the original source of the review is Google. I called 4 places trying to get same day service on a Monday at 3pm for our AC not working and this wonderful beacon fit me in within 2 hours. But that isn't the only reason for 5 stars. Everyone was so nice. From the lovely woman I spoke to on the phone (should have written down her name, started with an M) to Juan Perez who came out to figure out the issue. He was very transparent the entire time, said up front we didn't even need the thing we thought we did (🫠 to us), got our new thermostat installed, went up into the attic to figure out what my husband messed up, and checked out the unit outside. He was patient while explaining what happened to me, telling me what might be causing our intermittent issues, and offering several realistic solutions with no pressure to commit to anything. He was so thorough and I really appreciate the pictures and the kind explanation of what he saw. And to cap it off, reasonable pricing?! As all of those in Texas I'm sure, I hope we don't have another AC issue any time soon, but I know who I'll be calling first if we do 💜Posted on Google mabp119Trustindex verifies that the original source of the review is Google. Really liked their clear details on what needed to get done on my AC unit. Juan (technician) definitely knew his job and was very informative about what needed to get done. Great experience!Posted on Google Karen De La CruzTrustindex verifies that the original source of the review is Google. When our compressor died at 10 p.m. on a Thursday night, I immediately started worrying about getting through a hot summer weekend without AC. I called several companies, but I was set on working with Altruistic AC because they were close to home and had outstanding reviews. Their reputation absolutely lived up to the hype. Ramon was incredible throughout the entire process. He took the time to walk me through all of my options without any pressure or upselling. As a woman home alone while my husband was at work, I especially appreciated how respectful, honest, and patient he was. He made sure I felt informed and comfortable every step of the way. In the end, I knew replacing the system was the right decision for our home. The team moved quickly to get everything ordered so they could begin work Saturday morning. From start to finish, they were efficient, professional, and focused on doing the job right—not just doing it fast. What stood out even more was how much they genuinely care. The owner checks in on both customers and employees, and the team even made sure our pups were comfortable throughout the installation. We are customers for life. I can’t thank the Altruistic AC team enough for their responsiveness, professionalism, and care during a stressful situation. Thank you, Les, Ashley, Melanie, Ramon, and the entire technician team for getting our AC back up and running so quickly!Posted on Google Jamie ShepardTrustindex verifies that the original source of the review is Google. The Altruistic team completed a through review of our home's outdated HVAC system, and gave us recommendations but also presented options that could be tailored to our current budget. On installation day of our new furnace and air handler, I received a text message with the names and photos of our install team so I knew who to expect at the door. Bryan and Alberto were friendly, courteous, and efficient--and answered all of my questions with care. I was very pleased with the quality of their work and would definitely work with them again. We look forward to a continuing maintenance service with Altruistic AC. Update: We've been very pleased with the service teams who have come out for our continued maintenance. Ramon today was very knowledgeable and got our system back in tip-top shape! He kindly explained all of the adjustments he made as well, so we could keep up the improvements on our own.Posted on Google Maria AllenTrustindex verifies that the original source of the review is Google.

Ramón came out after hours to fix my AC unit and, he was very professional and knowledgeable.

Altruistic AC was a great to work with and extremely fast. A tech was there within about an hour. Ramon was amazing- Super kind and professional. He explained clearly, and was very patient when I asked him to explain everything over FaceTime to my spouse. He got everything fixed quickly. Will without a doubt call them again if we need service. They even texted a little personal bio and a photo of the tech to expect beforehand, which was a nice touch! Thanks.
