Two years ago I bought a water softener and filtration system from AHW.  They carry good products at reasonable prices.  I really like the service they provide.  Easy to get appointments, quick response time, professional technicians, always very helpful.  They call to remind me when my filter needs changing.  This year Gerardo changed my water filter.  He was very prompt, thorough and professional like everyone I've dealt with at AHW.  Highly recommend this company if you need prompt, reliable, affordable service.
