The trains on the District, Hammersmith & City and the Metropolitan lines do have air conditioning. These lines are sub surface lines with larger tunnels and trains than the deeper tube lines, thus they have the space for the equipment and to expel the hot air.
The Metropolitan Line is a Subsurface Line of the London Underground. It runs between Aldgate/Baker St and Amersham, with branches to Uxbridge, Chesham, and Watford. It has 34 Stations, and a very unique service pattern, with Fast, Semi-Fast, and All Stations services.

Wear light clothing. Even if you think you might need to wear a jacket, when you are on the hot Tube, it's likely you'll want to take it off immediately.

It might be shocking for you to hear that Buckingham Palace doesn't have an air conditioning system like the one in your home.

The Metropolitan line is the oldest underground railway in the world. The Metropolitan Railway opened in January 1863 and was an immediate success, though its construction took nearly two years and caused huge disruption in the streets.
With an increased capacity of ten percent and walk-through air-conditioned carriages, the new trains have improved accessibility and are more energy efficient. They are currently undergoing driverless trials in Germany and were also spotted in Austria (they were made in a factory in Vienna).
The Jubilee line is a line on the London Underground. It runs from Stanmore in north-west London to Stratford in east London. The color of the Jubilee line on tube maps is gray.
