Who makes it
inferred We could not match this system to a certification record of its own, but in Senville LETO: 3 of 3 certified systems in this series have ENERGY STAR ratings identical at every test point to a record Midea certifies itself (see each product's page for the records). Identical certified figures usually mean one underlying model sold under two names; they do not say who assembled the unit.
