"They were great to work with and more competitively priced than culligan. We were selling the home the water system was going into and needed to get the work done quickly before closing to address issues on the inspection report. They were great to work with and very responsive. We ultimately had installed a basic water softener, UV system and new sediment filter housing."

"Although this company tends not to be "warm and fuzzy", they provided an honest assessment of my home's needs, were professional, and offered the best price, by far, compared to other water treatment businesses. I interviewed four companies and, as of right now, I'm glad I selected Aquascience. The installation technicians were professional and efficient. So far, I have only good things to say about the company."

Customers say: Quick response

"I swear I wrote this review back in May, but apparently not. Nick is amazing: knows what he's doing, is friendly and professional, and the service is fast and great! I can't recommend these guys strongly enough. Scheduling was easy, and Nick really went above and beyond making sure our previously-abandoned house could safely pump water from the basement up to the attic. He repaired a bunch of broken pipes and made sure everything was set and ready before leaving - even though that meant he was stuck with us for much longer than anticipated. His work was top-notch - he should be your first choice for any well, pump, or plumbing need."

"Joe is very experienced and very professional to replace my well pump, bring up the well cap to above ground level and installed house water filter. He discussed the job in detail and gave a fair quote. He came on time and did the job at high quality. He cleaned up everything before he finish. He took the 5% Angies list coupon as well. Will use him again and highly recommended if you need well pump service!"

"Ralph was our first call once we submitted what we needed. He was professional, happy to answer any questions and head right over to take a look for himself. He sent me a quote for review, and after getting similar prices from other providers we decided on HV Water because Ralph made my husband and I comfortable and as if he was doing this on his own house. The install day was spotless, both installers were professional, meticulous and thorough. Cannot recommend these guys enough. Thanks again for an amazing job."

"Installed new boiler, indirect hot water heater, and rebuilt our well water system adding conditioning and softening. We have acidic well water that has been a problem. Now, everything has been corrected and works great. The new boiler is smaller and quieter. Very professional and completely trustworthy."
