Called this company when a local competitor told me I would need to replace my entire water softening system. When they arrived (within 24 hours) they said my issue was caused by frozen pipes outside not the system itself. Because of their knowledge of the system and how they addressed the actual problem instead of taking advantage of someone who isn't familiar with water softeners they saved me unnecessary work

Highly ethical knowledgeable company and I couldn't say enough good things.

Paul came out on a Thursday, the unit was installed on Monday and have not seen anymore rust stains forming on the shower and tub. The water is crystal clear and noticeably softer when taking a shower, clothes are softer and not orange from the iron in our water. Completely satisfied with the service and install. Thankyou Lindsay water conditioning for fixing our water!!
