Great service and very knowledgeable staff. They did a free in home assessment and water test. I was given a very fair estimate of what water treatment equipment I would need to remediate my heavy sediment and hard water. The assessor also had recommendations for future upgrades to my home's water. 10/10 would recommend to anyone.
Had an appointment in Bedford for 1/12. Service Rep was on time and changed a filter and delivered salt for the water treatment system. Excellent service and very friendly. I will always use Culligan!
They are great but I was not there that day I was next door for a haircut at salon Elio
Will came and gave a professional and informative assessment and estimate for our radon and ph issues.Jarrodd was our installer. He gave a friendly reminder call, showed up on time, was dressed professionally, and followed current safety guidelines.In addition to the awesome new system we have, we will be forever thankful to Jarrodd for saving our chickens! He was outside the house, up a ladder, and heard the neighbors dog running into our yard and going after our chickens.Jarrodd jumped into action and grabbed the dog to save our family pets 🙂 Our 7 and 8 year old sons have raised the chickens from 2 weeks old. We can't thank him enough for going the extra mile! ❤️
Very impressed with the Manchester Culligan of New Hampshire location! Cathy, the operations manager answered my questions and promptly scheduled our service. Andy, the service tech was very thorough, efficient, and friendly. I was doubly impressed that I didn't have to ask him to wear a face mask while servicing our whole house and RO filtration systems. Thank you!
Met with Will to go over options, the next week Jarredd did my install.Great job by both, very professional company. Highly recommend them.I have the whole house water softener and R/O drinking water systems.Incredible difference.
