What exactly is included in this package?

Thank you for your question. This system includes the outdoor condenser, the indoor air handler and a programmable, communicating thermostat. For a complete installation a few other accessories, which can be purchased separately, will be required. The recommended and required accessories are listed on the product page. They are divided into 2 sections- one is for the condenser and one is for the air handler. These accessories can be located under the "add to cart" button. For more assistance, please give us a call.
