Cooling coils sometimes called A-coils are where
all the removal of the heat in your home or
business occurs. A- coils got their name from
their shape of an A. Trane currently has
developed a cooling coil completely made out of
aluminum. The age old problem of pin holes
developing in the copper u-tubes is remedied.
Aluminum tubing does not pin hole. No
electrolysis ever appears in aluminum.
