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.

We carry all necessary replacement and service parts and components in large quantities and make them available during and after the warranty period.

Ask a Question
  • If I have a triple zone mini split and already have two 9000 btu heads at 25ft each. I realize the outside unit comes precharged for only 75ft total of line. But can I add the 3rd head at 50ft from outside and add more coolant from a certified A/C tech, will that work?

    Yes, that would be completely fine to do.

  • what gauge is the control wire?

    It is 16 AWG and 4 leads.

  • Does this line set fit 9000BTU 3/4ton 19.5 SEER? Model WYS009AMFI19RL-16

    For 9,000 BTU 19.5 SEER you would need to select the 1/4"-3/8" diameter option.

  • What are the sizes of the flare nuts on the ends of these copper line sets? That way I know what wrenches I need to purchase for my torque wrench

    Piping Diameter vs. Flare Nut Size:
    1/4" = 5/8"
    3/8" = 13/16"
    1/2" = 15/16"
    5/8" = 1-1/16"
