What size system do I need?

Sizing depends on your square footage, ceiling height, insulation, and climate. We can help estimate the BTU you need, since an oversized unit cycles too often and cools less evenly.

Single zone or multi zone?

A single-zone unit conditions one room from one outdoor unit, while a multi-zone system runs several indoor heads off one condenser. Your room layout decides which makes sense.

Does it need professional installation?

Most mini-splits need a licensed technician for the refrigerant line set and electrical, though some pre-charged kits are designed for capable DIY. Confirm the requirement before you buy.

Does it heat as well as cool, and how efficient is it?

Most mini-splits are heat pumps that both heat and cool. Look at the SEER2 and HSPF ratings in the specs to compare efficiency and expected running costs.

The questions our counter answers most, before the first box ships.

Talk to Our Team

Is this suitable for my application?+

Each product lists its wear layer, finish, and use ratings in the Specifications above, so you can match it to residential, commercial, or wet-area use. If you are not sure it fits your project, our specialists will review the details and confirm the right product before you order.

What is the lead time?+

Most in-stock orders are processed within 2-5 business days, then ship by ground or LTL freight depending on size and weight. Transit time varies by destination, and any made-to-order item shows its expected production window at checkout.

Do you price-match the trade?+

Yes. Builders, designers, and developers unlock trade pricing through our Developer Program. Apply once and your account receives member pricing across categories, plus dedicated support for large-volume orders.

How do I make sure the color matches?+

Screens and lighting vary, so our specialists will confirm the exact color, finish, and texture details with you before you commit. For larger orders we pull from the same dye lot where possible, and a small overage helps keep everything consistent.

What if my freight arrives damaged?+

Inspect your shipment on arrival. If anything is damaged, photograph it before unloading, note it with the LTL driver on the delivery receipt, and report it to us the same day, so we can file the carrier claim and ship free replacements.
