Benefits and Drawbacks of Duct-Free Mini-Split Systems

Prior to we constructed a brand-new home, I 'd never ever heard of mini divides. What could they be, some type of tiny frozen dessert or something? No.

Mini divides are actually ductless heating-and-cooling systems. They look something akin to what you have actually most likely seen in hotel spaces, though residential designs nowadays are smaller sized and more streamlined.

A mini-split system has 2 components: an indoor air-handling unit (or systems) and an outdoor condenser. The components are connected by a channel, and no ducts are included.

Mini-split technology has been around for thirty years, and it's used a lot in Europe and Japan. Like a fridge, a heatpump uses electrical power to pump refrigerant, moving heat from one location to another. When that heat is being moved from the outdoors to the within a house, that's the heating mode. When heat is being moved from the inside of a home to the outdoors, that's the air-conditioning mode.

So small divides can provide both heating & cooling in one. They are typically created to cool and warm a single space or zone, and there might depend on 4 indoor managing units linked to a single outdoors condenser.

Mini splits are wrong for every single space, however there are certainly advantages for specific applications. Here are a few places you may consider setting up such a system:

• A house that has no ductwork, like one that has formerly had radiant or electrical baseboard heat. One outside condenser can run as much as 4 indoor air handlers, so you could individually control four rooms/zones with a single mini-split system.

• Spaces that are not regularly occupied. You can turn off the mini-split system and close the door to save money.

• Additions or sheds where extending or installing ductwork is not practical.

• Spaces that are adjacent to unconditioned spaces (like garages, attics, and incomplete basements) where ductwork would be exposed to harsher temperature levels.

We have our mini-split system in the perk space over our garage. The garage is unconditioned, so running ductwork through that area would be a big energy loss liability for our HEATING AND COOLING system– a waste of cash. We utilize that bonus offer room as a guest room, and it is unoccupied much of the time. We can close the door when nobody exists, and that's 400 square feet we're not paying to heat or cool.

Mini divides have no ducts and therefore can prevent the energy loss (up to 20% or 30%) that comes with forced-air systems running through ductwork. Mini splits can be held on the wall or a ceiling, and some even come as freestanding units.

Although the mini-split system does not look the best, it is quiet and it does keep the space incredibly comfortable. And you can save cash by not heating and cooling a room that you do not regularly utilize.
