Ductless Mini-splits cool air without ductwork. Since hot air rises and cold air falls mounting the cooling section compactly on the wall, near the ceiling allows the unit to remove heat more efficiently and deliver cooling directly to the space where you need it. Automatic swing louvers and multiple fan speeds allow you to control the amount and direction of the airflow to maximize comfort.

3946Mini-splits are great too:

  • Cool only the areas you want and not the areas where you are not
  • Individual zoning at the push of a button, putting you in total comfort control • less than 5% cooling loss occurs in insulated refrigerant lines versus up to 40% through ducts
  • Requiring just a 3 to 4” diameter hole in the outside wall means less mess, better home aesthetics, and improved security, unlike a window unit.
  • Halcyon models mount high on the wall so they don’t disturb your view.
  • Mini-splits generally add value to your home and are more efficient than old window units, saving you money.

Now for the more technical stuff…

Inverter Mini-split Benefits

Compared to the common on/off controlled compressor, the inverter controlled compressor runs at the proper revolution to provide the best efficiency and reduce losses. When the maximum capacity is not required, the compressor revolution is decreased. This means the input power decreases too, which results in increased system efficiency. Another advantage of the inverter is the ‘soft start’. The compressor starts at minimum speed, avoiding high inrush current [4 to 6 times compressor full load amps] associated with conventional on-off type compressors. ‘Soft start’ reduces the instantaneous peak demand associated with AC equipment starts.

What is an Inverter?

An inverter air conditioner is both a converter of AC [alternating current] to DC [direct current] and an inverter changing DC to simulated frequency adaptable AC. The active filter and bridge rectifier rectifies AC by flattening output to create a DC power supply. The IPM [Inverter Power Module] uses electrical components such as transistors and diodes to switch and chop created DC to make simulated AC at the required frequency and voltage.
