Don't always reach for duct restrictions when balancing HVAC systems! This real-world case study shows how a simple fan speed adjustment solved a hot master bedroom issue that multiple service calls couldn't fix. The customer's bedroom stayed hot despite upsized ductwork because the high fan speed was cooling the house too quickly, causing short run times and inadequate air circulation in the occupied room. By reducing the fan speed, the system ran longer and moved more air through the problem area. Remember: fix the foundation issues first before adding restrictions that might worsen static pressure problems.
