The answer to 'air duct sealing not cooling' is that poor duct sealing can prevent proper airflow and cooling in your home. Leaky or unsealed air ducts can cause your HVAC system to work harder, leading to uneven temperatures, high energy bills, and potential system failure.
Common causes include improper installation, damage over time, or gaps around ductwork connections. Symptoms include rooms that don't cool evenly, high utility bills, and your HVAC system running constantly. Solutions may involve sealing ductwork with mastic sealant or metal tape, or having a professional duct inspection and repair.
