We are often asked:
Should I use my furnace or air conditioner during construction?
Unique Indoor Comfort’s answer is always the same:
No, you should not use your furnace or air conditioner during construction. Equipment operation during construction can void manufacturer warranties.
Construction dust and especially the dust from drywall and hardwood floor refinishing can cause havoc to your HVAC equipment. The dust can damage many components and can result in expensive repair that could have been avoided.
The picture on the right is of a blower wheel from a furnace that was running during construction. Our service technician found the entire furnace packed with drywall dust. The built-up dust caused the blower wheel to become out of balance, subsequently causing damage to the variable speed motor, that caused the variable speed motor’s ECM control to short out. This was a very expensive repair to three year old furnace; in addition to the costs of cleaning the furnace, evaporator coil, and the duct work.
