Overloaded circuits can put your home’s electrical system at risk. Large appliances and HVAC units can cause lights to flicker when they power on, because they’re drawing a large current from the circuit. This could point to inadequate wiring to the appliance or a circuit breaker that isn’t quite up to snuff.
