I just copied/pasted an answer I came up with mere minutes ago on a similar question...
A price ceiling is the maximum amount that sellers can charge for a good or service (G/S). An example of this is rent in a large city like New York. Lets just say that the tenant can only charge $1500 a month for rent in one of his apartments (theoretically). This will cause a shortage in apartments because of the amount of people who can afford the rent, and the amount of tenants who take their apartments off of the market because they will actually lose money if they rent it out. With the lower monthly payments for rent, the tenants will be reluctant to make repairs on the apartment due to how much they actually receive. There will also be a rise in black market activity for apartments, the renter will pay extra for rent under the table.

Price floor is a minimum and price ceiling is a maximum.
A price ceiling is characterized by a price set below the current market price.
A price ceiling is the legal maximum price that may be charged for a particular good or service.
A price ceiling prevents a price from rising above the ceiling. It represents an upper limit on the price of something. If wheat has a price ceiling of $400 per metric tonne, $400 is the highest amount any what supplier can charge. If the market price for wheat is below the ceiling, say $200 in this example, then the ceiling has no effect on prices; the ceiling is not binding. If the market price is higher than the ceiling, supply and demand cannot reach equilibrium and there is a shortage in the commodity. Artificially low prices result in demand that exceeds supply. The price, however, remains stuck at the ceiling.

a price ceiling results in a shortage because quantity demanded exceeds quantity supplied. it can increase consumer surplus but producer surplus decreases by more causing a deadweight loss in the market.

Binding Versus Non-Binding price ceilingsA price ceiling can be set above or below the free-market equilibrium price. For a price ceiling to be effective, it must differ from the free market price. In the graph at right, the supply and demand curves intersect to determine the free-market quantity and price. The dashed line represents a price ceiling set above the free-market price, called a non-binding price ceiling. In this case, the ceiling has no practical effect. The government has mandated a maximum price, but the market price is established well below that.In contrast, the solid green line is a price ceiling set below the free market price, called a binding price ceiling. In this case, the price ceiling has a measurable impact on the market.

A price floor can cause a surplus while a price ceiling can cause a shortage but not always.
A price floor is the minimum price set by the government where as a price ceiling is the maximum price sellers can charge for a good or service.
