We have used Culligan San Diego for over 10 years. We rented a softener for 4 years and then purchased a system when we bought our home. We have always had great service! They are friendly and helpful on the phone and quickly send a repair guy when needed (and we’ve only needed a repairman 1 time in 6.5 years of owning our system).
