    We recently acquired a home that had no pressure regulator, and the high water pressure was causing…read moreissues throughout the house. 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!

    This is my first time using C&C plumbing and I found them on Yelp based on their positive reviews…read more They were very quick to respond to my inquiry and were able to provide a fair quote. Brayden was professional, friendly, knowledgeable and he took the time to clearly explain the issue and the necessary repairs. When an additional problem was discovered, Brayden helped identify the correct replacement part, and once it arrived, he returned on the next available day to complete the project. Thank you!

    Just Right Services - The two installers from Just Right Services, Chris and Guillermo were great. Post-install shot along with me.

    I needed to address my AC not working suddenly right before summer. I landed in just right services…read morebecause they had the quickest turn around. Everything was resolved quickly and instead of charging me a good amount for a one time service, they offered a twice a year tune up plan for less, and would include this visit as covered. Took them up on it and have already gotten in my summer tune up with a winter tune up coming soon. For my summer tune up, Brandon was super friendly, fast and efficient. Above and beyond my expectations and the service was a lot easier than I thought it would be. Great experience overall! Glad I've contracted their services and am a member of their HVAC maintenance program.

    Summer is around the corner so I wanted to get a tune up for my HVAC. I inquired through yelp and…read moreit messaged 5 places so I just went with the earliest appointment. I had low expectations as my previous technician with a different company from last year barely did anything and did not even check our drain line inside the home. McShane was our technician and he's the reason I'm even leaving a 5 star review. He explained what he was doing and answered all my questions. He was respectful of the property, used shoe covers before entering, and asked permission before moving things around. You notice those little things when you've had a bad experience in the past. I would say the value is also worth it. It was $85 for the tune-up. I was obviously looking for something cheaper but you get what you pay for. Overall great service!! This company will now be my go-to for my HVAC needs!

    Our 15 year old water heater started leaking and I called our go to plumbing company that we have…read morebeen using for many years now. 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.

    A few weeks ago we woke up to find a bubble in our dining room ceiling from water that had been…read morefilling up while we were asleep! 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.
