"We have used H2O care since we bought our home a few years ago. We recently had an emergency situation and needed our filtration system replaced. They were super responsive, very knowledgeable and the system was reasonably priced. They consistently exceed our expectations- We highly recommend H20 Care!"

"Everyone I encountered with through NNN water solutions was super helpful and extremely knowledgeable. They were very patient with me as I was very nervous to comit to purchasing but they answered any question or concern I had. Installation was quick the guy was done within a few hrs. I normally don’t bother writing reviews but I’m so excited to have my new water system! I have really bad eczema and since having the new system my skin is so much less irritated. It is amazing the difference clean water will do"

"I recently moved to Braintree and was looking to put in a full house water filtration system. I used Angi to find companies and immediately got a phone call from the owner of the company on a Saturday. He was unbelievably helpful and the customer service from Leisa was above and beyond. I would highly recommend working with them."

"They were beyond wonderful. This is a smallish business run with the professionalism and skill of a much larger one. Personal service, prompt and knowledgeable, and fairly priced. I cannot say enough that is good about them. My first experience was on an emergency basis one Sunday morning when my heat failed. My usual plumber was away and recommended I contact Local, which I did to my delight. He came when promised, troubleshot and replaced defective parts on my old system, and arranged for an electrician to come the next day to replace a defective relay (which was not available on a Sunday afternoon). He has been extremely helpful and capable and is full of integrity. I cannot recommend them highly enough. I'm an English major and words fail me. I feel as if I've gone back in time to an era when service mattered to those providing it as well as those receiving it."
