What is Through-the-Wall Heating?

Through-the-wall heating systems are self-contained units installed directly into an exterior wall. These systems are commonly used in:

• Apartments and condos

• Older homes without ductwork

• Rental properties

• Additions or converted spaces

• New Construction

They often include PTAC units (Packaged Terminal Air Conditioners) or wall-mounted heating systems that provide both heating and cooling.
