Why Homeowners Are Switching to Tankless Water Heaters

Traditional water heaters continuously heat and store water, even when you are not using it. Tankless water heaters work differently by heating water only when you need it. That means greater efficiency, unlimited hot water, and lower monthly utility costs.

Benefits of Tankless Water Heaters

Endless hot water for showers, laundry, and appliances
Lower monthly energy bills
Longer lifespan than traditional water heaters
Compact design saves space
Reduced risk of water damage from tank leaks
Cleaner, more efficient performance
Environmentally friendly operation

Most tankless water heaters last up to 20 years with proper maintenance, making them a smart long-term investment for homeowners in Lago Vista, Lakeway, Cedar Park, Leander, and throughout the Austin area.

“These guys are the real deal.”
Preventative maintenance is the backbone of Lantz Home Services. Once again being part of their PM program I avoided a complete shutdown of our grinder pump. Lantz Master Plumber Justin Barnett arrived and I thought all was well until he requested that I take a “peek” into what I would describe as a total catastrophe about to happen at any moment. The grinder system was a horror of failing pump and sewage accumulation and related nasties. Justin told me my options from doing nothing to fixing it with 3 options, which were clearly defined with costs and various replacement components and when it would be finished. We chose wisely. Justin returned with all of the components and in 4 hours it was stripped completely and reassembled with new components. Justin is organized, articulate, educated and polite. Bravo Lantz Home Services PS. I worked in industrial Preventative Maintenance for 25 years. These guys are the real deal.

“I truly appreciate their responsiveness and professionalism.”
I had a great experience with Lantz Home Services. We ran into an electrical issue at our lake house late in the day, and I honestly didn’t think we’d be able to get an electrician out that evening. When I called, they reassured me that someone would be available—and they delivered. Nick, their electrician, arrived around 7 PM and had everything resolved by 9 PM. He was prompt, thorough, and very courteous throughout the entire process. He quickly diagnosed the problem and fixed it efficiently, all at a very fair price. I truly appreciate their responsiveness and professionalism. I highly recommend Lantz Home Services and will definitely be using them again in the future.

Zachary was beyond helpful! He jumped straight to the problem, made sure everything was properly working, walked me through the fix and was straightforward from the get go about what the potential issues could be and what the estimated repairs were as well! He kept me informed and even shared pictures when I couldn't be there right away. After everything was done he put everything back the way it was. This was a grinder pump drainage pipe repair. The site looked as if he was never there! Five stars.

“Highly recommend if you want accurate diagnostics and fair, trustworthy service.”
I had an excellent experience with this HVAC company and especially with Moses, who came out for a second opinion. After a previous technician tried to convince me that I needed a full system replacement (on a 4-year-old unit), Moses took a completely different and highly professional approach. He performed thorough diagnostics before suggesting anything and took the time to properly assess the system instead of jumping to conclusions. He confirmed that there was no leak, no major component failure, and that the system was actually in good working condition. The issue was likely electrical, not something requiring expensive replacements. This immediately put my mind at ease. What really stood out is their honesty and integrity. Instead of pushing unnecessary work, they were transparent about the fact that no major repairs were needed. They also documented their findings and shared everything clearly, which builds a lot of trust. Huge shoutout to Moses for being knowledgeable, thorough, and genuinely looking out for the customer’s best interest. It’s rare to find this level of honesty in the industry. Highly recommend if you want accurate diagnostics and fair, trustworthy service.

“Would highly recommend to anyone I need of their services.”
Excellent service, fast, and professional team. Willie Krueger was the tech who came through, he solved plumbing issues that had bugged me for almost 10 years in about 20 minutes. Will absolutely use them in the future for anything I can, and would highly recommend to anyone I need of their services.

- Jonathan J.
“I can not speak highly enough about the professionalism we received!”
Zac was very cordial and made sure I was aware of what he diagnosed and what it was going to cost. We had one of our Heat Pumps replaced last week, the Techs were John and Landyn. The response was amazing as was the changeout. I can not speak highly enough about the professionalism we received!

- Gerald P.
The folks at Lantz Home Services installed this Tankless Water Heater for me and were absolutely amazing! They put up new wall paneling to cover some wall defects I had from the old tank water heater. So happy with my new water heater!!

- Nichole W.
“They take pride in their service”
Mark and Willie came out to the Christian Brothers Automotive pflugerville location and were able to handle the commercial plumbing issue that 3 other plumbing companies were not able to figure out. We will only be using them form now on the difference was night and day between them and the others. On a side note Willie’s service truck was the cleanest most well organized service truck we all had ever seen!!! They take pride in their service and we appreciate that in our service industry as well!
