Packaged A/C Systems
The nice thing about a packaged air conditioning unit is that it’s self-contained. It does it all- it heats and it cools. There is no furnace or a-coil involved here. It sits on a pad outside the home and it hooks up to the ducting in your home with two big air tubes, called “flex-ducting”. The only part of this system inside the house is the ducting and the thermostat, so you can use that furnace compartment as a storage bin if you go with a packaged system.
You will either have to be a certified technician, or have somebody who is working on your home, to buy a packaged unit!
