Most of the electronics in your household run on DC power. The first thing most devices do is convert the AC to DC power. These devices (transformers and diode rectifiers) aren't particularly susceptible to frequency (or minor voltage) fluctuations. That's why a lot of power packs on laptops will work on 110/220 50/60Hz with only a change in the plug. Even clocks don't rely on the 60Hz for timing; they use a crystal that vibrates at a much higher frequency.
Motors and compressors use the AC to produce motion, and the change will cause a change in rotation speed, but nothing to worry about.
Older CRT type TV's and tube type devices used the AC for their circuitry, often amplifying voltage and/or frequency, so they would be more susceptible, but there are few of these devices left.
