9 unintended consequences of closing vents
Let me now summarize the problems I've described above that can result from closing vents in your home. The first thing that happens is the air pressure in the duct system increases, which may give rise to these negative consequences:
Increased duct leakage
Lower air flow with PSC blowers
Increased energy use with ECM blowers
Comfort problems because of low air flow
Frozen air conditioner coil
Dead compressor
Cracked heat exchanger, with the potential for getting carbon monoxide in your home
Increased infiltration/exfiltration due to unbalanced leakage , as I described last week
Condensation and mold growth in winter due to lower surface temperatures in rooms with closed vents
