Especially for those with limited space in which to store their HVAC units, a packaged unit can be fairly beneficial due to its spatially efficient design. Package units are located either on the roof or on the side of a building, and they house a number of combined HVAC systems, like the packaged air conditioners that include a compressor, coils and air handler, the packaged heat pumps that contain a heat pump and often an electric heat strip, a packaged gas-electric unit that combines an air conditioner with a gas-powered furnace, and a packaged dual-fuel unit that contains a heat pump and a gas furnace. There are no indoor components of this central air system.
You have chosen a 2.5-ton heat pump, meaning that the space in which you intend to heat or cool is 1,250-1,500 square feet. If you’re looking to equip your heat pump with the ability to heat your space as well, you should also look into purchasing a heat kit to go with the heat pump. If you live in a milder climate, go with a 5 or 10 kW heat kit, and if you live in a colder climate, be sure to purchase a 15 kW heat kit.
Disclaimer: Before making a purchase, you should always check first with your qualified installer to figure out what unit is best for your home or space.
