DIY vs Non-DIY

  • DIYCOOL™: No soldering, No refrigerant handling, No gauges, No vacuum pump or licensed contractor needed.
  • Includes revolutionary Quick Connect adaptors for easy DIY installation
  • Full warranty on compressor AND parts, even if you self install
  • Cost of install: $0 plus your time invested to install the unit
  • Price for unit with the additional install accessories needed for the installation is about 15% less(sounds like a great deal)
  • Estimated cost average for professional installation by an HVAC technician about the same cost as the equipment or more
  • Warranty in place but only if installed by a licensed HVAC company(no warranty otherwise)


The 4 Main Operating Modes
  • Cooling: 18,000 BTUs to efficiently cool spaces up to 800 square feet.
  • Heating: 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: 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: 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: A “set it and forget it” 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: 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 3PAMSHQC18 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 – 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.
  • 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 “SWING” button on your remote to start and stop.
  • Louver Angle Memory – 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.
  • 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 “EC” 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.

The Critical Components

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.
