At House

At House handles plumbing work in Irvine with a focus on tankless water heater installations and ongoing service calls. The company takes care of descaling flushes on these units along with warranty repairs on water softeners. Reviewers name technicians including Hiro, Ken, and Makito who show up for the jobs, plus Naomi who handles the initial phone contact. They also put in new Rinnai tankless systems and keep older ones running past the decade mark.

Customers call when their tankless water heaters need cleaning or when a unit stops producing hot water. One job involved a full descaling flush on a heater installed a couple years earlier, while another covered a warranty fix on a softener paired with a 13-year-old Rinnai model. The work leaves the equipment running quietly and efficiently again, with homeowners noting they got their hot water back without extra parts pushed on them. Installations replace old tank systems with compact units that take up less space.

The crew responds fast to calls and books next-day visits when needed. Scheduling stays straightforward, prices stay competitive and fair, and the technicians keep the job sites clean while they work. Reviewers point out the team shows up on time, explains findings in plain terms, and avoids any pressure for unneeded services. The same company returns for maintenance years after an install, which keeps the process simple for repeat customers.

“I can't recommend At Home enough! They recently serviced my tankless water heater with a descaling flush, and the experience was outstanding from start to finish. Their team is always friendly, professional, and punctual. Their pricing is very competitive, and what really sets them apart is their honesty and integrity—you never feel like they're trying to upsell you on services you don't need. They also installed my tankless water heater about 2½ years ago, so it's great to have a company that stands behind their work and continues to provide excellent maintenance. The technician was efficient, knowledgeable, and took the time to answer my questions while making sure everything was running perfectly before leaving. It's not often you find a company that's honest, reliable, reasonably priced, and genuinely cares about their customers. At Home has earned my trust, and they'll continue to be my go-to company for all my plumbing and water heater needs. Highly recommended!”

“We had such an excellent experience with At House. Naomi was very kind and helpful over the phone. She responded quickly, explained exactly what needed to be done, and made the entire process very easy and reassuring. Hiro came out to service our 13-year-old Rinnai tankless water heater. He was professional, knowledgeable, and took the time to thoroughly inspect and clean the unit. He clearly explained what he found and gave us confidence that the heater should continue to run well for a long time. From the initial phone call to the actual service visit, everything was handled quickly, accurately, and professionally. It is rare to find a company that responds this fast and makes the entire process feel so trustworthy. Overall, this was a truly outstanding experience, and we will definitely contact At House again in the future. Highly recommended!!”

“Ken serviced our tankless water heater and completed a warranty repair on our softener. Honesty, next day service, ease of scheduling, fair prices, and clean efficient work. I really appreciate Hiro and this business.”

“Excellent service! The technician demonstrated true expertise with our water heater, which is much more specialized than standard plumbing. They were professional, had a great attitude, and offered a very reasonable price. We are so glad to have our hot water back and will definitely be loyal customers from now on.”

“Just had a Rinnai tankless water heater installed at my house. The technician, Makito, was very professional and efficient. The unit is compact compared to a conventional water tank system, runs quietly, and is energy efficient. I’m confident I made the right choice—highly recommended.”
