    Water softener and filter. Prompt response, friendly, professional. Great price. Would highly recommend! Got the hybrid, water feels great! Clean as pipe job for my no knowledge eyes!

    Before

    Imagine you have a problem and there's people who can solve it for you, and do it right the first time. I called them on a Friday and it was installed on Tuesday. My old gas water tank heater ( GE ) was 22 years old, not yet broken but it was time to say goodbye. I bought the gas tankless Rinnai from Home Depot. Rinnai is a Japanese brand, and At House is a Japanese-American contractor Initial in-home visit with At House was very efficient with run down of items needed to be addressed. Contractor ( Hiro, my hero ) very responsive and pro active in accommodating to my concerns: install location, gas pressure. Lucky, I didn't need to do ( 1/2" to 3/4" pipe for Rinnai ) gas line modifications. Cost estimate was accurate and very reasonable. Very quick to schedule appointment and job done very neatly, methodically, promptly and professionally. This is not their first rodeo. ( Thank you " M, " You're the Best ! , the mirror said ) The end result is a masterpiece of " art, " with all the piping beautifully lined up. Not sure if anyone can put a monetary value on happiness. I was thrilled with the installation. I had been dreaming of this Rinnai ( RXP 199iN ) for the past decade and finally dream came true. Hot water came on fast. Machine is in a closet so not much noise when it runs. At House has the Big-city experience and know-how with kindness / honesty of small town feel that really puts my mind at ease. Am a very Happy and thankful that I found them on Rinnai's website as an ACE Pro Rinnai certified contractor, and reading Yelp reviews like what you are doing right now.

    These guys are ROCKSTARS! Every interaction, from the initial contact with the owner (Hiro), to the techs that came out to my house, this business operated like a WELL-OILED MACHINE! With WORLD CLASS service experience and friendly techs who treated the installation job like they were working on their own house. I'm super happy. Clean install job, cleaned up after their job and best of all their pricing is super competitive. ALL the right reasons to HIRE "AT HOUSE". They took care of my warranty registration and gave me guidance on proper maintenance

    We Just replaced our old water heater with a tankless Rinnai and we love it. Hiro was very easy to communicate with, transparent with pricing and service. Great value, competitive price, amazing service and product. Highly recommend this business

    I had my water softener installed by Hiro and his crew previously. Sunday my Noritz tankless water heater went on the blink and stopped working. I called "At House " and spoke with Hiro since he installed my water softener previously. The unit wasn't in stock , however, Hiro committed to have the unit and installed Tuesday. As promised Hiro's assistant arrived on time and started the installation. Both Hiro and his assistant were professional , friendly and patient when I asked questions . The Rennai tankless water heater is working perfectly and the water is even hotter than the previous unit. Hiro replaced all of the hardware fittings and lines to the new unit. When they were finished they thoroughly cleaned up the area and took the old unit with them . I highly recommend "At House" if you need a tankless water heater or water softener installed. Great job guys! Thank you !

When we decided to replace it and also add a new water filtration system, they were incredibly helpful--presenting multiple options and even giving us a discount that made a huge difference. Their installation work was absolutely top-notch. Both Zachariah and Cooper went above and beyond; they are detail-oriented professionals who clearly know exactly what they are doing. We also had to fix a water leak coming from our ceiling, and Simon thoroughly inspected everything and accurately located the source of the leak. The very next day, Simon and Jacob returned to complete the repair. They were professional, efficient, and truly exceeded my expectations. I highly recommend Olson Superior Plumbing!

Joshua Z was the technician who came out both times for our problem. He was very knowledgable, and upfront about everything that was going on, why he would do what he is doing, and the best course of action if it was something that could not be done yet. Being in a commercial building did add a layer of complexity to our situation, and Josh did a great job telling us what our next steps should be since the issue turned out to be worse than either one of us expected. If I ever have any plumbing issues, I know who I would call.

I spoke with Cameron of C & C Plumbing to discuss the matter and hired them. They installed a quality pressure regulator, and it made an immediate, noticeable difference. Our appliances are happier, the knocking sounds that used to happen whenever the irrigation system turned on are completely gone, and our house pressure is finally back to normal. They showed up on time, quoted a very fair price, and were clearly knowledgeable about which quality parts to use. The clamping equipment and materials they installed are top-notch--built to last and give us years of worry-free service. It's obvious they take pride in using the best rather than cutting corners. I highly recommend them for any plumbing work. They were professional and reliable. We scheduled a follow up visit and they installed a Moen Flo unit as well that will give us further piece of mind. (the blue tape on the photo is covering the water-gauge since I didn't want it to get wet and collect water spots over time making it difficult to read). Thank you C&C Plumbing!

Thank you Efficient plumbing yet again for your service and timely installation. When we called my husband scheduled the plumbers Steve and Hector to come out the following day. They had a look at my water heater and determined it needed to be replaced. We had been wanting to get a new tankless water heater for quite some time but my husband wanted to wait until we were in need of replacing our current hot water heater tank. Steve gave us a quote for replacing our current 75 gallon water heater with a tankless Navien model that would go in our garage in the same place as our old water heater. The price was fair and we agreed to go with the work. Later that morning Efficient Plumbing ordered our tankless water heater, delivered it, removed our old water heater and installed the new tankless water heater for us. They did an amazing job with all the necessary modifications to make the conversion from tank to tankless and we were thrilled with the end result. We now have endless hot water that we once never had. Efficient Plumbing has once again came to our rescue when we have been in need of a plumber! They are the best plumbers and I will continue working with them on any future projects or improvements that we may need.

This is any homeowners nightmare and I called Efficient Plumbing right away. We have used them for many years and sadly this wasn't our first water leak. Evelin answered the phone and walked me through on how to shut the water off to the house immediately to stop the water damage. Hector came out within the hour and got to work diagnosing our issue. He is knowledgeable and very experienced and we always feel like we are in good hands. Our ceiling was opened and it turned out to be a copper pin hole leak on the water line in the ceiling above the dining room that feeds our master bathroom. Hector skillfully repaired the water leak and also advised us to consider a whole house repipe since this was not our first leak. They gave us their estimate the same day for the whole house repipe and even offered to credit the repairs made with Hector towards the repipe which was a big help. We decided to move forward and had them repipe our whole house the following week. They got it done in one day and everything went great! A few days later the drywall was patched up and we were all done! There are many many plumbers in our area but after years of consistent quality workmanship and customer service, I only use and trust Efficient Plumbing.
