  • Refrigerant Leakage Detect 
    Indoor unit shows error code "EC" and stops automatically when refrigerant leakage is detected. This protects the compressor from high temperature damage due to refrigerant leakage.
  • Anti-cold Air Function 
    Indoor fan speed is regulated automatically from the lowest grade to the setting grade according to evaporator temperature when the unit just starts heating operation. This function can prevent cold air blowing out to avoid discomfort to the users.
  • Emergency start
  • Low Ambient Cooling 
    With built-in low ambient kit or special designed PCB, outdoor fan speeds can be changed automatically according to condensation temperature. The air conditioner can run cooling operation even when the outdoor ambient temperature is down to -15°C.

Shipping Details

We only ship to the 48 contiguous United States. No shipments to APO/FPO addresses, AK, HI, PR or other US Territories. No international shipments. Due to the size and the weight of our equipment, we can only utilize well known freight companies for shipping. Each shipment will be palletized, strapped down and wrapped in stretch film to protect against damages during transit.

Upon arrival you may ask the driver to break down the palette into individual cartons to unload the goods from the truck easily. We generally include Lift Gate service. This will arrive as curb side delivery. Trucker will unload the goods from the truck to ground level. If you must have inside delivery service, there will be an additional charge which needs to be paid separately and coordinated with the freight company. We also allow free pickup from our main distribution warehouse, located in Miami area. Equipment we sell is not suitable for express or courier shipping because of their weight as well as high risk of damages.

Due to higher than expected order volume and busy sales season, larger orders may take an extra 3-5 days to be prepared for shipment. We are working around-the-clock to ship out all orders in a timely manner, and will communicate with you if there are any unexpected delays or questions.

We prepare each shipment within 72 hours after the receipt of payment (only during weekdays). Trucking companies usually pick up same day or a day after we call them that the shipment is ready. The transit may take any time between 5 to 8 business days and in rare cases up to 12 days.

We will provide tracking information after shipment. Please contact us in case of any shipment delays. CHECK YOUR INFORMATION CAREFULLY TO SUBMIT THE CORRECT DELIVERY ADDRESS, UPDATED EMAIL AND A VALID PHONE NUMBER with your order. Someone must be present to receive the cargo at the time of delivery. Delivery company will call your phone number to setup a delivery appointment for residential deliveries. If your phone number is not valid, the cargo can not be delivered and will be returned at your expense within 3 days of arrival. If the delivery is refused or can not be delivered, it will be handled as returned merchandise.

Upon arrival, count all cartons and compare with the number stated on the delivery receipt before signing. Open the cartons and inspect the goods carefully for any damages. All products have been inspected under strict ISO regulated facilities and leave our warehouse in perfect condition. Report any shipping damages to the freight carrier on the delivery receipt and file a claim. Also contact us with the description of damages and pictures, etc. Although rare, certain freight damages can occur and we are here to help.
