I've had many over the years. We bought our house in 2011 and the system was already installed.
Perficut - AFter a few years dropped the residential, went commercial only
Shades of Green - Bought the client list from Perficut. Shady is in the name, unmarked white vans, techs were worthless
A+ - Irrigation was actually okay. Went to them for mowing/fertilizer and had to drop them. Awful quality of work and customer service after the fact was terrible. My wife was in the hospital having a baby and I was trying to fight with them to come mow my 18" grass they'd been ignoring.
BOSS in Johnston - They were okay with irrigation, but lousy on the lawn care. Didn't last a full season with them either. Would rut up the yard after rains and generally didn't care about quality.
DeVries - I've had them for 4 or 5 years now. The lawn care aspect is okay, but I DIY all that again now. Irrigation Dept is good. Have the same dude year after year, does the backflow and repairs anything in the spring. And shutdown in the fall is a piece of cake.
