LG Electronics Art Cool™ Premier Duct-Free Air ConditionerOver the last 5 or so years we've been installing more and more duct-free air conditioning systems in order to meet demanding budgets, schedules and complicated renovations. Duct-Free air conditioners (often referred to "mini-splits") have become the go to solution for lots of our customers on tight budgets and the results are often very impressive. Duct-free air conditioners offer several key advantages over more traditional air conditioning systems including:
- Cost - Duct-Free or "Mini-Split" air conditioners can be 25% to 75% cheaper than more traditional air conditioning systems.
- Design Flexibility - One of the biggest benefits to duct-free systems is the flexibility of the installation. As the name implies, these systems have no duct work which means installation takes up less room for large unsightly duct work.
- Quiet Operation - Duct-Free A/C units are often VERY quiet and so quiet in fact that they are almost impossible to detect under normal use.

What Is A Duct-Free Air Conditioner?A duct-free (ductless or mini-split) air conditioner is an air conditioning system that has no duct work. The system includes a normal compressor unit that sits outside and then an air handler that gets mounted in the finish space instead of a more traditional air handler that might be in the attic. The wall mounted air handler blows cool air into the room that it's installed similar to a window air conditioner except it's not located in a window. As you can see above our new LG system includes an outdoor compressor (shown in the photo just above) and an indoor air handler (shown in the photo of the shop above). The main power for the unit (220V) runs to the outdoor unit. The power for the interior unit is run from the outdoor unit along with the refrigerant lines. So once the unit is installed it's very similar to having a regular A/C unit in your home minus all the duct work and huge capital investment.
Installation & OperationAs with any regular air conditioning system you'll need to hire a licensed mechanical contractor to install a duct-free system like the LG Art Cool™ Premier Duct-Free System Model LSN090HYV. Installation consists of installing the outdoor compressor unit that we previously discussed, installing a new electrical supply to it (shown ab0ve), installation of the indoor air handler, and then running drain lines and power lines from the indoor unit to the outdoor unit. A typical installation can be done in one day with very little disruption to your home. Our installers needed about 6 hours to completely install the system and have it up and running. The placements of the interior and exterior units are the most critical decisions. Several factors should be considered:
- Proximity of the outdoor unit to the indoor unit. Typical installations require the two units to be approximately 50' apart for standard electrical and coolant lines. Lines up to 75' can be used in some situations.
- The most efficient and easiest installations occur when the inside unit is hung on the same "wall"as the exterior unit is located.
- Proximity of the outdoor unit to the house electrical service. Power for the exterior unit requires a dedicated circuit that runs from the unit directly to the house electrical sub-panel. Keeping the distance to a minimum can help keep cost of installation low.
