A/C 101: An air-conditioning breakdown
Central A/C Types (HVAC)
Central systems are typically used in larger buildings and homes with HVAC forced air systems, using ducting systems to distribute cooled air throughout the space, alongside any heating or air filtration systems. The two most common configurations in are Packaged and Split A/C systems.
Packaged Central Air Conditioning
A packaged central air conditioner sits outside your home and cools the air inside by venting hot air outside and circulating cold air through your home's ducts. It's more expensive upfront than ductless units, but is more efficient and cost-effective in the long run and simplifies maintenance. However, the unit is exposed to outdoor elements all year.
Split Central Air Conditioning
A split central air conditioning system has an entirely external single unit with the compressor and evaporator assembly that vents hot air and an internal evaporator coil that cools air inside your home. It works with your furnace and distributes chilled air throughout your home through existing ducts. It costs more upfront than individual units for each room, but is much more energy-efficient than individual units. Unlike a packaged system, only part of the system is exposed to outdoor elements year-round.
These systems do not make use of a home's existing ducting or HVAC system. They function on their own and can be installed in virtually any home. Like their central air counterparts, they are divided into two categories: Split and Portable.
Split Ductless Air Conditioner
A split ductless air conditioner has an indoor unit mounted on a wall or ceiling and an outdoor unit with a compressor and condenser. It cools and dehumidifies the air inside by using refrigerant and circulating cooled air back into the room. The outdoor unit releases excess heat. This type of air conditioner is good for homes without ductwork or an HVAC system and is useful for adding cooling to specific rooms.
Portable Ductless Air Conditioner
A portable ductless air conditioner is a self-contained unit with both a compressor and evaporator assembly that can be easily moved from room to room. It has a hose that ventilates hot air out of a window or through a hole in a wall. The unit cools and dehumidifies the air inside by using refrigerant and circulating cooled air back into the room. Some portable ductless air conditioners also have heating capabilities. One advantage of a portable ductless air conditioner is that it can be easily moved and does not require installation. However, it may not be as energy-efficient as a central or split ductless air conditioner, and it can be loud.
At Sterling, we carry, install, and service all major makes and models.
