"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."

"I selected Polar Plumbing because of the many positive reviews on Home Adviser. I was not disappointed. My ultimate selection of Polar as our vendor of choice was based on their total solution proposal to our heating and water issues. The primary interfaces were Ray and Jared. Ray was the communication link to the project and kept us informed throughout the process. Jared was the front man. His plumbing, heating and water treatment expertise was clearly evident. The project began shortly thereafter and the team was precisely on time and very professional. The oil fired boiler was installed the first day and the old oil burner and associated equipment were disposed of. The installation looked and performed great. The next day was the installation of a water treatment system, 2 Nest thermostats and baseboard covers. In two days our lives changed: reliable consistent heat and hot water, and the odorous sulfur smell was gone. Kudos to the Polar team."

"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."
