Shipping Frequently Asked Questions

Can I provide authority to leave for my delivery?

Your parcel will be delivered by a delivery service who does not take responsibility for any loss or damage. In certain instances, it may not be possible for a shipping carrier to leave a parcel with ATL instructions. 

For example sometimes it is not possible because of a secured building or complex and lack of instructions on how to leave the package at that location.

Frequently Asked Questions

How much will delivery cost me?

With one-click checkout, we make shipping easy and fast! Whether you order a single product or multiple products with different types of items, our flat rate charge will be applied to the highest item.

See the Shipping Tab or our shipping policy for more information.

Do I need to be at home when my unit is delivered?

Yes, someone must be available to accept delivery as we require a signature as proof of receiving goods. We recommend having an additional person at the door with you when items are delivered so that they can help bring your air conditioner inside.

How do I decide the size of an air conditioner?

  • When it comes to deciding which air conditioner is right for you, the first thing that matters is how powerful a device will be required. Air conditioners are rated by BTU and power output in kilowatts; however, buying an oversized unit isn't as economical since they use more energy than smaller ones. What's important when purchasing one is determining what size room your home needs cooling down from- so don’t forget the appropriate sized appliance!

    When selecting the right size air conditioner for your space, the below applies:
  • For a room 10m2 to 20m2, a 2.6kW unit should cool the room;
  • For a room 20m2 to 30m2, a 3.5kW unit should cool the room;
  • For a room 30m2 to 45m2, a 5-6kW unit should cool the room; and
  • For a room 45m2 to 65m2, a 7-8kW unit should cool the room.

However, we always recommend seeking expert advice before making your final decision. Our friendly, knowledgeable team members can help you find the right solution for your home and your budget.
