The hardware is the smallest decision
Control4 is a platform, not a product you unbox. The same processors, keypads and touchscreens can produce a home that everyone in the household uses daily, or one that ends up ignored. What separates them is the thinking that happens before installation and the tuning that happens after it.
So the useful questions are not about brands. They are about process: who designs the system, who documents it, who programs it, and who you call in two years.
Ask to see documentation
A capable integrator can show you cable schedules, rack elevations, keypad engraving schedules and device positions marked on plan. If that documentation does not exist, the electrician is guessing and you will pay for the guesses later.
Ask when they get involved. Joining at design stage costs very little; joining after plaster costs a great deal.
Ask how it will be commissioned
Lighting levels, audio tuning and scene timing can only be set in the finished room, at the right time of day, with the furniture in place. If nobody is returning to do that, the system will feel blunt.
Ask who explains the house to your household, and whether the system is backed up and documented at handover.
Ask about the years afterwards
Firmware moves, streaming services change and households grow. Support is not an add-on; it is part of owning an integrated home. Ask what remote support looks like, how fast a response is, and whether they take on systems installed by others, a team confident enough to inherit somebody else's work usually knows what it is doing.
