Ductless HVAC System

A ductless HVAC system (also called a ductless mini-split or ductless multi-split) is any HVAC system that can heat and/or cool your home without the presence of ducts. Ductless HVAC systems are designed to control the temperature in just one room or space, as opposed to the entire home.

What is a Ductless HVAC System?

A ductless HVAC system, or mini-split, is a type of air-conditioning and heating system that uses individual, wall-mounted blowers to provide temperature control in one room or area. Instead of using ductwork, the individual units are connected by a refrigerant line set to a single outdoor condensing unit. These systems are a great option for room additions, sunrooms, garages or areas of the home not serviced by ductwork that need to be warmer or cooler.

How does a ductless HVAC system work?

A ductless HVAC system works by circulating refrigerant through a line set connected to one or more indoor air handlers. The air handler is typically mounted on an interior wall, and it collects and circulates the cooled or heated air throughout the room. This air is then returned back to the outdoor condensing unit, where the refrigerant is compressed and circulated back to the indoor units in a continuous cycle. This process of transferring heat from indoors to outdoors helps keep your home’s temperature at ideal levels. 

Types of mini-split systems

Ductless systems are configured in several ways. There are ductless air conditioners, ductless heat pumps that can both cool and heat a room, as well as ductless zoning systems that allow you to tie several rooms together.

Installing a ductless HVAC system

If you’re interested in installing a ductless HVAC system, it’s important to consult with an experienced technician who can help determine the best type of unit for your needs, as well as make sure that the installation is done correctly and safely. Additionally, proper maintenance is important to ensure that your ductless HVAC system runs efficiently and effectively.

Ductless HVAC system maintenance

Regular maintenance is essential for keeping your ductless HVAC system running efficiently. This includes changing the air filters regularly, as well as checking and cleaning the evaporator and condenser coils. Additionally, you should make sure that the refrigerant levels are correct and that all parts of the system are in good working order. An experienced technician can help you with this process if needed. For maintenance advice and troubleshooting tips, check out our ductless systems maintenance guide.

Overall, a ductless HVAC system offers many benefits for homeowners looking to maintain comfortable temperatures in their homes without using traditional central heating and cooling systems. However, it’s important to consult with an experienced professional before installing one of these systems in your home. With proper installation and regular maintenance, a ductless HVAC system can provide you with efficient, cost-effective temperature control for years to come.
