Air conditioning doesn’t come cheap, so there are a lot of small venues or halls which do not have air conditioning units in the UK. You can hire an air conditioner for your party to keep the air fresh and cool inside during sweltering summer months. There’s no jaw-dropping high price either.
It’s ideal to have are conditioning if the venue isn’t well ventilated naturally, and especially when running PA systems & electrics that can generate a lot of heat. The unit itself is relatively small but will provide enough cool air to keep the heat away in a small hall, house or pub.
