Thank you for choosing Carrier! You can feel confident
in your selection because the same pride in craftsman-

Chapel in Rome, the US Capitol Hall of Congress, and
thousands of other installations worldwide has gone
into the construction of this unit.

heat pumps provide a high standard of quality in per-
formance, workmanship, durability and appearance as
