What to know before buying

Listing details to confirm

Listing details are inconsistent: the title gives 208-230V while the specifications list 208 volts, and the dimensions appear as both 101D x 22W x 31.5H centimetres and 100.99 x 22 x 31.5 cm; 12.5 kg. The feature copy gives 21 SEER2 and 9.5 HSPF2, while the details field labels 21 as SEER. Confirm the electrical requirements, exact efficiency ratings and dimensions for the selected listing before purchase. The manufacturer recommends licensed HVAC technician installation and says to keep the unit upright for 24 hours after receiving both packages.
