LG Duct-Free Technology

A duct-free system, also known as a “split” air conditioner system, is made up of or includes two units: an indoor unit to deliver conditioned air to the room, and an outdoor unit to remove heat collected from the space. The compact refrigerant lines run between the two units. The system eliminates the need for ductwork. Duct-free systems are not just ideal for older homes that have no ductwork and room additions, but also in rooms that just never seem to be the right temperature and are never comfortable. 

At LG, we want you to be able to get a good feel for how our products work. In this section, we provide you with product functionality, tutorials, sales-focused, and general usage videos all with the goal of helping you better understand, and see how LG Duct-Free technology works for homes, residential spaces and light commercial areas. 

Williams Air Curtains

Williams Air Curtains are the most effective barrier available for keeping building environments free of airborne contaminants and keeping conditioned air inside where it belongs. As a crucial component of any heating or cooling system, air curtains allow for free movement of people and merchandise, while preventing the loss of conditioned air. They also prevent hot air in the summer, or cold air in the winter, from penetrating the building and disrupting the system performance and raising or lowering the standing temperature. 

In areas when clean air and hygiene are required, such as hospitals, restaurants and food prep environments, air curtains keep insects, gas fumes and other harmful airborne contaminants out, keeping people and their food safe.

LG Ductless Features & Benefits....

LG Offers a lot in the HVAC product line!

Product Benefits


For ease of installation, energy efficiency and quiet performance, duct-free systems are the smart choice.


Whether you’re creating a quiet, comfort controlled room, or simply want to heat or cool an area without expensive ductwork, LG’s duct-free systems set a new standard for efficiency, great looks and comfort.

Duct-free systems are much simpler and economical to install because they only have three basic parts: an outdoor condensing unit, an indoor unit, and the components that connect the two.

Duct-free systems are ideal for home or office additions to replace unsightly window units, and for renovations or retro-fits where it’s important to preserve the building’s original appearance.


  •  Fast installation – With no costly ductwork, duct-free systems can be installed in places where conventional ducted systems simply can’t go.
  •  Incredibly quiet – Indoor units operate at just 26 dB (the level of softly rustling leaves!).
  •  Custom temperature control – It’s easy to precisely maintain the temperature in each room.
  •  Attractive design – Choose from a wide variety of elegant looks to enhance any interior decor.


  •  Reduced energy costs. You can cut your cooling bill with LG’s energy-efficient technology. Look for our Inverter Air Conditioners featuring high-performance variable-speed compressors and our Multi Power System™ with exclusive dual compressor technology.
  •  Cleaner, healthier air. Plasma air purifying technology ensures cleaner, fresher air.
  •  Better air circulation. Computer controlled louvers and fan speeds minimize temperature differences in the room.
  •  High-speed cooling. Powerful Jet Cool feature quickly cools warm rooms down to a comfortable temperature.
  •  Built to last. The exclusive GoldFin™ Anti-Corrosion coating helps keep your system running like new for years.


Ash is bad for your HVAC System!!!

Forest Fire Ash is not just on your car....

Make sure to check your filters.... 


Health experts say if you are sensitive to the smoke in the air from the wildfires or need to be outdoors for a long time, you should wear the proper mask to filter out the smoke.

But you may still be getting exposed to the smoke indoors, including inside your home and your car.


As a result, area HVAC service technicians are getting lots of calls to check on or change out smoke and ash clogged furnace air filters.
