Our story
We saw neighbors overpaying. So we fixed it.
Most companies charge many times what a tankless flush should cost — it's opportunity cost for them, not a specialty. And if you skip it, your unit falls out of warranty the moment something goes wrong.
We saw the gap in the neighborhood and built a business around one job, done properly: the annual cleaning your tankless water heater actually needs.
What we do

Rated 5.0 across San Diego.
"Steve has the best customer service and best price for tankless water heating maintenance services. He is prompt and keeps you up to date during the process. I highly recommend him!"
"Steve has been a godsend to the Civita community. Not only are his prices reasonable but his 'let me help you and give you information' personality has me referring him to all my neighbors. Genuine, honest, and fair."
"I recently did my first annual flush / descaling of my tankless water heater. I was getting ridiculous quotes elsewhere, and found Steve Terry who is much more reasonable. Apparently this is all he does and he is licensed. Great guy, very nice and thorough. Highly recommended!"
"I highly recommend Terry's Tankless Water Heater Cleaning. Steve is friendly, provides excellent service, and is very knowledgeable. Best pricing for this service that I have found. He has serviced my water heater for years. During the most recent visit, he professionally cleaned my water heater and also saved me from an additional expense as he was able to correct a fault code that was occurring."
"It truly is a pleasure having Terry work on our water heater annually. He does a great job going the extra mile cleaning the system and truly being a great value in what he does. Would recommend him any day of the week."
"Steve is a professional who helps with tankless water heater maintenance. I appreciate his clear communication, fair pricing, and ability to help quickly! It feels great to work with him directly versus your standard larger service providers. Evening and weekend availability, which is a huge plus!"
