How much electricity comes into a house?

What type of electrical system is used in homes?
In North America, most appliances use 120 volts, that is why most wall receptacles in homes, offices and public places will be wired with one hot wire and the neutral. These systems are known as single-phase, two wire systems (1-ph, 2w).
How are houses electrically wired?
Most homes have three-wire service—two hot wires and one neutral. Throughout the house, one hot wire and one neutral wire power conventional 120-volt lights and appliances. Both hot wires and the neutral wire make a 240-volt circuit for large appliances such as air conditioners and electric furnaces.
Do all houses have 220v?
Most houses today have two 110 volt wires and one neutral wire running into the house from the local distribution system. These wires can run underground or above ground. If there are two 110 volt wires running to the house, then the house has 220 volt service and appliances, such as dryers and air conditioners.

Are houses DC or AC?
AC – Alternating Current
When you plug things into the outlet in your house, you don’t get DC. Household outlets are AC – Alternating Current. This current has a frequency of 60 Hz and would look something like this (if you plotted current as a function of time).

You can also look into the gang box of your existing thermostat. If you have black and white wires you likely have 120V. If you have black and red wires you likely have 240V.
How do I know if my power is 110 or 220?
However, there are a number of key differences between a 110 outlet and a 220 outlet:
