I was referred to Culligan by a friend of mine, who had been using their services for a very long time. I called Culligan to come for an estimate and arranged a meeting with them at my house. The salesperson came by and supplied me with some brochures of their low to high end products. I'm not a fancy person and just wants something to work well, especially since this is the first time I've been on well water. The salesperson was helpful and offered to test the water. He brought in the "test tubes", collected the water, where it turned out I had a bit of iron and sulphur, and the water was obviously hard. He advised us that the iron and sulphur levels aren't very high, but we definitely needed a water softner. No big deal...kind of expected that. He said my neighbour across the street needed a sulphur filter - as soon as you turned on the tap, you could just smell that fowl sulphur smell. It just depends. So we were flipping through the book and found a decent unit for about 2400, unit+service. I tried to get a better deal but he wasn't budging. Anyhow, he did eventually dropped $50 (pretty sure this is the norm that he would give a customer if you tried a little bit hard). I'm sure I could get it for cheaper from another company, like Nelson, but I wanted to deal with a fairly reputable company and didn't want to waste time. Plus, this fellow was pretty good. Anyhow, a few days later, we noticed the sulphur smell! I called the salesperson a few days after the initial smell and asked about the filter. That's another ~$2600. Anyhow, I got everything installed together so the serviceman only needed to be in my house once. The units has been working well, no real big problem - aside from the sulphur smell once in a while when the levels fluctuates. One other thing: I'm a big believer of water testing, even if you have a bacteria killing system. I couldn't figure out why my water was still resulting in "high overgrown bacteria count". So, after I called the health inspector, I spoke with my salesperson and he guided me through it. It was pretty helpful since my water results came out clean! So, the service, as a whole, was great - whether it is about the units, installation, or simply a water problem! He was there by email AND phone. They have bags of salt to sell and deliver, for those interested. I mean, it's like $3 more for a bag than if you go to a regular home depot or whatever. It's not bad if you can't lug it down or up your house.
