When to Install a Ductless Air Conditioning System

 

What’s the Difference Between a Ducted and Ductless Air Conditioning System?

Air conditioners provide cool air through two forms of delivery: ducted or ductless systems. The majority of homes in the U.S. are built with air ducts made from sheet metal that run from the main air conditioning unit to each room in the house. The ducts are hidden in walls and the air is delivered to each room through vents. In ductless systems, the refrigerant from the outdoor condensing unit is sent directly to an air handler located on the wall or ceiling of a particular room.

While a ductless system can have several benefits, many homeowners with existing ductwork will be better off from a financial and comfort perspective by using a ducted system.

Benefits of Ductless Air Conditioning System

• Easy for a contractor to install (no ductwork)
• Some flexibility in the location of the air handler
• Ability to cool the home by specific zones
• Quiet when operating

Concerns with Ductless Air Conditioning System

• Reduced overall indoor air circulation and increased humidity can lead to comfort and air quality problems
• The appearance of the air handler on a wall or ceiling in each room
• Higher cost of ownership for a whole-home solution if your home already has central AC
• External refrigerant lines which could cause energy losses and aesthetic concerns
• Serviceability and ease of repairs could be a problem as the unit gets older

When to Consider Installing a Ductless Air Conditioning System

While we don’t recommend a ductless system for most homes, there are several situations where a ductless system should be considered over a traditional ducted one. These include:

• Room additions or adding cooling to a garage or workspace
• Cooling smaller, older homes without existing ductwork
• When space is at a premium and ducts won’t fit
• When replacing a less efficient window/room air conditioner

The bottom line on Ductless Air Conditioning Systems

Your comfort, humidity and long-term reliability should all be factors in making a smart decision. As with any important HVAC question, it makes sense to talk with a professional.
