Culligan of Lancaster does a great job maintaining the customer’s home RO system. They make it easy to schedule and the service engineers are very friendly and informative about what they are doing. Service is always great, prices remain affordable. The products work great; the water was horrible when the customer bought the home, but after having Culligan installed it’s like a whole different water—fresh and clean. Equipment does not take up much room. Deliveries are on time. The service is the best of the best.
