How Does a Ductless System Heat?

When people think of keeping a home warm with a central heating system, they often think first of a furnace. A furnace is a type of “forced-air” heater that spreads warmth throughout a building by first raising the temperature of the air, then using a blower fan to send the air out into rooms. In order for a furnace to distribute its heated air, it must have ductwork leading from the cabinet and to the vents into the room.

However, not all forced-air heating systems require ducts like a furnace does. A popular option for home comfort today—ductless mini split systems—allows for central heating without needing any lengths of space-consuming ductwork. Ductless mini splits are an excellent idea for new home construction, home expansion, remodeling, and older houses that lack room for duct installation.

Purl’s Sheet Metal & Air Conditioning offers installation of ductless mini split systems, as well as other systems for central heating in Fresno, CA. Call our technicians today to find out more about how we can keep your home warm no matter how cold it gets outside.

The Basics of Ductless Mini Split Systems

A ductless mini split system is a type of heat pump, which means that instead of creating heat by burning fuel or through electrical resistance the way a furnace does, it moves heat from one place to another. In operation, ductless mini splits are similar to air conditioners, except they can shift heat in both directions: from inside a home to the outside (cooling) and from outside a home to the inside (heating).

How does a ductless mini split send heat around a home without ducts? Instead of using a single indoor cabinet where heat is released and then sent into a duct network via a blower, a ductless mini split has multiple air handlers mounted in rooms around the home. The outdoor cabinet connects to the individual air handlers through power and refrigerant lines. Each air handler contains a blower and a coil; the coil releases heat, and the blower sends it directly into the room.

Aside from the advantage of not needing any ductwork, ductless mini split systems offer zone heating for a home: each air handler can be controlled separately from the others, so a home only needs to receive heating in rooms that require it. This makes ductless mini splits great energy savers.

A ductless mini split heat pump is not ideal for every house, so make sure you call Purl’s Sheet Metal & Air Conditioning and speak to our Fresno, CA heating professionals before making a choice for home comfort. We install, repair, and maintain a variety of heating systems, and we will help you find the best way to keep your house warm.
