Common questions

Will a 9K cool a big room?
It's sized for up to about 350 sq ft. For a larger or poorly insulated room, look at the 12K or 18K.

What breaker does it need?
MRCOOL lists 18 A minimum circuit ampacity and a 20 A maximum breaker, on its own dedicated circuit. A qualified electrician should size the wire.

Can I plug it into an outlet?
No. It's 115V, but it's hardwired on a dedicated circuit with a disconnect.

Can I extend the line set?
Yes, up to MRCOOL's 75 ft maximum. Email us before ordering so we can match couplers to the 1/4 × 3/8 in line.
