I have very mixed opinions of this company. Their AC people have been great.
A plumber came out to our house to look at our water softener, and it was one of the worst experiences I've had with a repair company.
To start, the problem was already known. There is a missing float from our salt tank keeping it from filling with water. The system works perfectly otherwise.
This plumber started by walking through our garage without letting us know he was there. He superficially looked at the system and said he couldn't see a problem. When I discussed what I thought was wrong, he said he could replace the whole system for several thousand dollars, or I could just order a whole new salt tank from Amazon for $600, and install it myself.
No effort to look at the internals of the system or replace the missing part.
