Room Air Conditioners
Room or window air conditioners cool individual rooms, not your entire home, and are less expensive than central air-conditioning units. You can choose either a window unit or a portable air conditioner.
Central Air Conditioners
Central air conditioners circulate cool air using ducts and registers, providing even distribution throughout the home. A central air conditioner can last up to 20 years with proper maintenance, is more energy-efficient than a room air conditioner and is cost-effective if your home already has duct work.
Ductless Mini-Split Air Conditioners
These systems could be good options for room additions and small apartments, where installing ductwork isn’t feasible. The indoor air handlers are small and can be mounted on the ceiling or hung on a wall. They cost more than other cooling systems but are typically less expensive to maintain.
