Yes, but AC systems in households often times have other fail safe
mechanism that car ACs don't.

For example, the AC in my household has a failsafe that will disable
the compressor, if there is insufficient air flow (low pressure)
(usually caused by a dirty air filter).

I've had cases of an AC in the house having too little refrigerant, and
causing the condensation to freeze on the evaporator. This, in turn,
blocked the airflow from the AC system. Note that, in my house at
least, the low pressure failsafe wasn't triggered because of
this...there was plenty of air pressure...it just couldn't get through
the evaporator. A recharge of refrigerant fixed the problem.
