Early Start-Up of Permanently Installed HVAC Systems

Owners contemplating the use of temporary heat should understand the short and long term risks of using the permanent HVAC system for temporary heat. Permanent HVAC systems are specifically designed to provide comfortable, clean air conditioning for a tightly enclosed, soundly constructed building and not buildings under construction.

With rare exception, it is not in the best interest of the building’s owner to operate permanent HVAC system for temporary heating or cooling purposes during construction. Equipment specifically designed to provide temporary heat is available, both for rental and purchase, and should be used to meet temporary construction requirements.
