Lupin Inc. are the gold standard that other repair people need to hold to! My spouse and I purchased a basic water softener and started having trouble-called Lupin to get advice repair, he not only gave free advice but when we made an appointment for repair, and he discovered what was wrong, he did not charge us at all! (We went and got our own part and fixed it ourselves using his advice) My spouse and I continued to try to work with our basic softener but we realized we got a defective unit. (DO NOT BUY WHIRLPOOL WATER SOFTENERS!) We called up Lupin again, had him remove the POS softener and install a nice softener that was a flat rate with a very fair price, included 4 bags of softner salt and install fee. Clear communication, professional yet empathetic, punctual, and just all around fantastic. Cannot recommend enough if you are having water softener issues.
