Anthony did a great job installing our new system. He was very thorough in explaining what he was doing and how the system works.

My tech, Kade Kivari, was amazing. Extremely knowledgeable, helpful and friendly. He was clean, neat and an excellent representative for your company. I am extremely happy with Kade and with your company. Thank you!

Austin is true professional. He came to install my Whole House water filtration system and he done an awesome job. Thank you Austin for a job well done!

All service personnel are respectful and knowledgeable. They go out of their way to make sure everything is done well and correctly.

Arrived on time. Filters changed. All trash was removed.

Wouldn’t give me pricing over the phone. Plumber has to go and give me an in person quote, and if i say i don’t want to go through with the service then they charge a $50 “inspection” fee. Don’t recommend at all. seems like a money grab.

These guys are just consistently the best. They're efficient, friendly, and honest. Michael came to the house today to inspect our hot water heater and quickly diagnosed the problem, provided several no pressure options, and was very knowledgeable and great to interact with. Update: Johnethan came out for a service call at a later date. Still, my review stands. These guys are consistently the best.

Austin and his team did a wonderful job of installing our reverse osmosis water system. Would highly recommend he and his company CGC

Elvin was the best!!! Fixed our water softener system and made it look and feel brand new 😊

Excellent service

Water softener showed results immediately, definitely feeling the difference. Chris from the water testing team made the demonstration seamless and smooth, answered all my questions. Nickolas came out and installed the equipment quick and was also very knowledgeable in his field. Thank you!

Abraham was extremely courteous and professional! He provided a great quote and far better value than the other companies I spoke with. I look forward to the installation.

Anthony did a fantastic job replacing the old softener system with the newer and smaller system. The water is now super soft. Plus the new RO water system in the kitchen makes the water so clean. Thanks Anthony, you did a great job.

Great service and customer support

CGC Agent, Nickolas Macie, was courteous and very professional. He called to inform me of his arrival and departure and answered my questions about carbon replacement in my Kinetico Water Softener Tanks.

Michael was excellent. He explained everything perfectly. He went thru all the products and options.

Caleb went above and beyond to make sure we were satisfied. He did an excellent job.

We were very happy with our demonstration and explanation of the system. Abe was professional and prompt and left us with a firm understanding of the installation process.

The water softener stopped working. Same day service. Found the problem right away. Courteous, told me what needed to be done, scheduled it right away. Abel did an excellent job!

Joseph Morin was my installation technician, and what a hard working young man. Despite the 96 degree Florida weather, Joe did an outstanding job installing my new water softener system. The main water line enters my home at the opposite end from the garage, requiring an outside insulation. Joe worked 5.5 hours nonstop in direct sunlight to get the job done. 5 star treatment.
