Hot & Cold Spots: Causes and Fixes

Uneven temperatures mean conditioned air isn't reaching every room evenly. Common causes:

• Leaky, undersized, or unbalanced ductwork — the most frequent culprit in multi-story and older homes.
• Poor insulation or no zoning — bonus rooms, additions, and upstairs spaces gain and lose heat faster.
• Blocked or closed vents and furniture covering registers.
• An aging or undersized system that can't keep up with the whole home.

Fixes that work

Duct sealing and balancing solves many cases. For rooms ducts can't reach well — additions, garages, bonus rooms — a ductless mini-split delivers independent, efficient comfort to just that zone without major remodeling. A technician can recommend the lightest fix that actually solves it.
