The transportation network from Heathrow is really quite excellent. You can access the brilliant London Underground system from stations at Terminals 2 or 5, which connects to the Piccadilly Line that can take you directly into the centre of the city in under an hour. A single fare costs 5.70GBP ($11.50), and they run from about 5:00am-11:30pm.
The fastest way into the city is probably on the Heathrow Express, which takes 15 minutes to get into London Paddington. A single fare costs 22GBP ($45). There’s also the Rail Connect, which runs into London Paddington too and takes around 30-50 minutes, but costs half the price.
There are a variety of buses, from coaches that run into the city centre, to ones that will take you to the overground rail system that runs through the city. All tickets can be purchased at the Heathrow Central Bus Station.
The most expensive way into the city is via taxi, which you can grab directly outside the terminal. The journey will cost around 45-70GBP ($90-140) and taking about an hour. However, you can book private mini-cabs which tend to be cheaper, though you have to organise this in advance.
