Central Air Conditioning

Central air conditioners, often referred to as “central air” or “split-system air conditioning,” circulate cool air through a system of supply and return ducts. Supply ducts and registers (i.e., openings in the walls, floors, or ceilings covered by grills) carry cooled air from the air conditioner to the home. This cooled air becomes warmer as it circulates through the home; then flows back to the central air conditioner through return ducts and registers. Learn how central air conditioners compare to other cooling systems.

Ductless Air Conditioning

Ductless cooling and heating systems (sometimes called split systems, multi-split systems, or split-ductless systems) can offer your home or business unmatched energy efficiency, performance, and control for your cooling and heating needs. It’s easy to keep everyone comfortable without spending a fortune on your energy bills.

Replace your inefficient window units, space heaters, and electric baseboard heaters. Ductless cooling units can be installed in home additions, new construction, condominiums, and apartments or to improve temperature control in specific rooms. Ductless systems can even be fit for buildings that currently use ducted forced-air systems.

Are you looking for a way to save on energy costs all year round? Having Hillside Heating & Cooling add a heat pump to your heating and air conditioning system is a great way to achieve this goal and much more!
