Uneven heating or cooling between rooms? Dit is wie je moet bellen

When some rooms are too hot while others are freezing, the problem usually lies in your HVAC ductwork, insulation, or system sizing. Common causes include blocked or leaking ducts, closed or misadjusted dampers, insufficient insulation in certain walls or attic areas, or an HVAC system that's too small for the space. An HVAC technician can perform a duct inspection, check airflow at each register, and recommend solutions like duct sealing, damper adjustment, or adding a zoning system.
