  • Cost of install: $0 plus your time invested to install the unit

Operation

The 4 Main Operating Modes
  • Cooling: 18,000 BTUs to efficiently cool spaces up to 750 square feet.
  • Heating:ย Efficient heat pump technology delivers 18,000 BTUs of heat, good for spaces up to 800 square feet.
  • This unit allows you to set your desired temperature from 62 to 80 degrees Fahrenheit.
  • Dehumidify:ย Enable DRY mode and the unit acts as a dehumidifier, removing more moisture than air conditioning alone. In this mode, you can remove 1.5 liters of moisture per hour, almost matching the energy factor of best-selling portable dehumidifier brands.
  • Fan Only:ย The unit offers 4 fan speeds in any operating setting or use the fan mode alone to circulate fresh air throughout your space.

Energy Saving Modes

  • AUTO Mode:ย A โ€œset it and forget itโ€ feature for eliminating guesswork. With your desired temperature set, enable AUTO mode and your mini split will choose the most appropriate operating mode to achieve maximum comfort in your space.
  • SLEEP Mode:ย Save energy and money by enabling SLEEP mode. The unit will adjust the temperature by 2 degrees towards a less costly operation: every hour for the first 2 hours, then locks in that optimal running state for the next 5 hours, before it shuts off automatically.

Smart Operation

The 4PAMSHQC18 model has a built in wireless smart controller. Simply download the Perfect Aire app, connect your smartphone or tablet, and you have a virtual remote controller. Switch between modes and program run times anywhere with a wi-fi connection.

Other Cool Features

Programmable Timer and Mode Scheduling
  • Set your system to turn on and off to save energy and money: Set TIMER ON and TIMER OFF times in 30-minute increments up to 10 hours, then 1-hour increments afterwards.
  • With the Perfect-Aire app and a Wi-Fi connection, you can even schedule times for the different modes to run โ€“ all from a smartphone or tablet.
4 Fan Speeds
  • Press the FAN SPEED button on the remote to cycle through Auto, Low, Medium, and High and find one that suits any situation.
Auto-Restart
  • In case of a power outage, the unit will automatically restart and revert to your settings once power is restored.
Auto-Swing Louvers & Angle Memory
  • The Louvers can be set to automatically swing back and forth for an even air distribution. Press the โ€œSWINGโ€ button on your remote to start and stop.
  • Louver Angle Memory โ€“ Keep your previously set louver direction every time you power on your unit.
The Turbo Button
  • Hit this button on the remote to reach a desired temperature even faster. Your best friend when having guests over.
Anti-Mildew
  • Turn off the unit from COOL, AUTO, or DRY modes and the unit will operate in a super low-power state to dry up the condensed water many other AC units leave behind, preventing the mildew problem many have known with other AC solutions.
Refrigerant Leakage Detection, Self-Cleaning, & Self-Diagnostics
  • The indoor unit will automatically display โ€œECโ€ when it detects refrigerant leakage.
  • LED Display codes on the indoor blower keep you in the know, letting you rest assured your timer was successfully set, indicating whether the unit is in defrost mode, self-cleaning mode, or simply indicating it is time to change your air filter.
Anti-Corrosive Condenser & Inverter Compressor
  • Perfect Aire single-zone units use a golden hydrophilic condenser to accelerate the defrosting process, improving the heating efficiency. This unique anti-corrosive condenser can withstand salty air, rain, and other corrosive elements.
  • The inverter compressor is programmed to run at optimum speed; set by the input frequency as it varies between heat requirements. This allows the unit to curb drastic temperature swings, keeping your space comfortable. Inverters use a different rotation speed than regular compressors, out-performing them in quietness, efficiency, and longevity.

Warranty: 7 Year Parts / 7 Year Compressor
