Never purchase the Carrier HVAC AC. We bought one AC whose internal copper tubes leaked in 4 months only. After repeated follow-up one day it got repaired. After 3 months it again started leaking and making cars like noise. One day it got repaired and the very next day its tube leaked once again. Carrier HVAC Customer Care responded that due to surrounding air and corrosion their AC won’t last for 4 months. that’s it.
