Existing Conditions

There are various electric resistance package terminal air conditioning (PTAC) units.  Electric resistance heating is a very expensive way to heating a building.

Retrofit Conditions

We recommend replacing the existing PTAC units with newer heat pump PTAC units.  The heat pump PTACs will operate more efficiently down to about -5°C, at which time built-in electric resistance heating would be turned on.

Further Benefits

Every suite will gain individual air conditioning.
