When installing HVAC systems during the construction of a home or building many of us are asked (or ordered) to run the system such as the heat during the construction phase of the structure. Often this is needed to help the drywall people cure the taping and plastering.

What are you guys doing about that? Are you operating the systems? If not, how do you tell the general or the subcontractors that this puts the system in jeopardy?

In many cases, the equipment warranty clearly states that this may void the warranty.

What do you do?
