When considering the purchase of a new air conditioner and heating system for your home or office, you will have to decide between central air conditioning or ductless. While the initial cost of installation is heavily weighted, the long-term costs of repairs, and efficiency should also be factored in.
Central A/C Duct Systems:
Duct systems have both outdoor and indoor components that are connected to one another by system of ducts. The cool air is circulated throughout your home through ducts by an air handler. Through zoning the duct system can be quite energy efficient by enabling the creation of different climates in different parts of your home / office by setting different temperature for each space.
Ductless systems are ideal when ductwork is impossible to install, they can be easily mounted on the wall or in the ceiling. The efficiency of ductless systems is in its delivery of warm or cool air directly into different areas in your home or business, instead of initially routing it through ducts. While central air conditioning is controlled through a mounted thermostat through the home, these ductless heating/cooling systems are controlled by its operating zone. Typically ductless units are used in new construction, additions, and multi-family housing.
While each has its own advantages, the specifics of your situation will go a long way in determining the right system. It is always best to sit with a licensed professional to consider the flexibility of your space, the existing components already within your space, your optimal zoning comfort, energy efficiency, rebates and the overall installation budget.
