Great and efficient service. We have been using Culligan for over two years now and happy with the service and solutions if there are any small hiccups happen.
Awesome company - no issues with delivery. The drivers are always friendly. And they are dog friendly.
I’m really pleased with the whole process. They were able to install the filtration and softener pretty quickly. I’ve noticed a difference in the taste of the water after a week or so. I don’t see a need to purchase bottled water anymore!
Good communication about our systems usage
Very nice and professional
Prompt, courteous, professional
When technician arrived, there was some difficulty getting in the door. But he was very patient and allowed me to make some phone calls in order to get him in the house. And was very kind and patient. Many companies would have just left. He didn't. That kind of service is rare these days. I greatly appreciated this.
Excellent customer service! You won’t find a better company than this!Thank you guys for all you do!
I had a whole-home water filtration system installed by Culligan, and I couldn't be more pleased with the entire experience. From Abby the sales advisor to the installation technician, everyone was professional, friendly, and knowledgeable. They made the entire process smooth and stress-free, and the installation was completed quickly and with great attention to detail. They took the time to make sure everything was working perfectly before they left. I highly recommend Culligan to anyone looking for a high-quality water filtration system and exceptional customer service.
We had a great experience with Mast Family Culligan! Josh Lanham, Senior Water Treatment Specialist, was friendly, knowledgeable, and never made us feel pressured. Rich Velez, our installer, was professional, courteous, and left everything spotless. We are very pleased with our whole-house water system and highly recommend them!
He did a good job..arrive on time
We LOVE Culligan. Great service from Alex, he goes above snd beyond to please. The whole Culligan team is TERRIFIC
I usually don't see our delivery man, but I know he is always on time because I check for the water about 7:15, & he's already been there! The few times I've been home, he's always put mÿ new bottles in the rack for me.He's very polite too.
Customer service is always Excellent !
Always great service from them
Culligan serviced our water softener today. They called me and the service was performed on time. I’ve been impressed with their products and service since installation last year. I would recommend them.
Alex did a great job does his job very professional
The installation was great. In and out in 1/2 hour. Everything was perfect.
Same day service call made and completed getting my system back up and running. Couldn’t ask for a better experience when immediate service is needed.
Techs were very pleasant and friendly
We had this system put in less then a year ago and continue to have problem with brown smelling and water as well as cloudy white milky water. Never had these issues on our old system. Really starting to regret getting this put in; hopefully, they can once and for all address whatever equipment issues that they are having and we can become part of the happy Culligan family. I'll update. Update, everything is now working fine thanks to our wonderful serviceman Josh. He found the problem and so far have had no further issues. Thanks Culligan
Ruben is the best!!!!!
Dan was great in selling the product. Rich was great installing the product. He was courteous, and did an excellent installation. Good job guys.

This company has been wonderful with our water delivery. Alisha is who helped us set up everything and whenever I have a question or change she responds immediately to confirm. Joe our delivery man is super friendly and very helpful, especially when we first started with setting up our cooler and delivery of water. I truly can't say enough how professional and quick they are for every single thing. I wish we would have set this up sooner. Everything is so well organized, which we love.
Everytime I call someone at Culligan they are friendly, helpful and knowledgeable. I've used them for a 5 gallon filter for 3 years. Never have I had a bad experience. Highly recommend them. My card was lost and I didn't pay my bill for months. The person on the phone removed my fees and was understanding of my situation. Talk about honest business.
Alex G. did a great job at installing our cooler. Thank you.

Usually, if your water smells like sulfur or rotten eggs, the reason is because your water has high Hydrogen Sulfide (H2S) content.

H2S is a gas that is released from the earth and finds its way into groundwater. It’s especially common in well water located near shale, sandstone, coal, peat, or oil.

(Occasionally, a rotten-egg smell in your water could also be caused by a water heater or by sewage pollution in your water. If you’re on city water, the most likely explanation is your water heater.)

A rotten-egg smell in your water may be strongest right after turning the water on, as heat forces the gas out of the water and into the air
H2S dissolves in water to create a weak acid that can corrode metal pipes

Negative Effects of H2S

In addition to potential health risks, having H2S in your water can cause all sorts of annoying problems. H2S in your water can:

  • Cause coffee and tea to be discolored and taste funny
  • Corrode metals (steel, copper, iron, brass), including silverware
  • Cause foods cooked with water to taste “off”
  • Create yellow or black stains in your bathroom and kitchen 

How Do You Fix It?

Here at Culligan, you can find everything you need to get rid of H2S and that sulfur/rotten-egg smell from your water.

The first step we have to take is to test your water, so we can be sure of the real cause of the rotten-egg smell.

Fortunately, here at Culligan we offer this service free. One of our water experts will come to your home to test the water (you can’t send it away to a laboratory because H2S is a gas and could dissipate during transport) and let you know the source of your rotten-egg smell. You’re under no obligation whatsoever. 

Culligan water treatment systems can completely remove the rotten-egg smell from your water
