Overview

At 24.0 SEER2 this is the highest cooling rating of any system in this group, and its 13.5 EER2 is the highest here too. EER2 is the one that tells you how the unit behaves on a design day rather than averaged over a season. Heating is rated 18,000 BTU at 11.1 HSPF2, and the system carries both ENERGY STAR certification and a cold climate rating.

Questions

Good to know.

Does this kit come with everything to install it?
It includes the indoor unit, the matched outdoor condenser, a remote, and a 16 ft insulated line set. Your installer supplies the disconnect, electrical whip, and any longer line set your installation needs. These items are not included or sold in our Accessories collection. Line set covers are sold separately.
What size room does a 18K BTU unit cool?
Published coverage of about 700 to 1,000 sq ft is an approximate guide only. Capacity depends on climate, insulation, windows, ceiling height, and layout. Have a qualified HVAC professional perform a load calculation and confirm the system capacity before ordering. Our sizing guide offers additional background.
Who installs it?
A licensed local HVAC technician handles installation, including mounting, refrigerant connections, and startup. Installation labor is separate and paid to your technician. Arrange installation with them. Estimated delivery: 7 to 13 business days, including processing and transit. This is an estimate, not a guaranteed arrival date.
What refrigerant does it use?
R-454B is the newer low-GWP refrigerant that replaces R-410A on current high-efficiency systems. It is more environmentally friendly and is what our BLU+ line runs. More on refrigerants.
How does shipping work?
Shipping is free to the lower 48 states. Estimated delivery: 7 to 13 business days, including processing and transit. This is an estimate, not a guaranteed arrival date. Large units ship LTL freight from California or Texas. Tracking is provided when the order ships.
