Ductwork & Airflow in Alpharetta, GA

If one room is always hotter than the rest, the problem may be in the ducts rather than the AC itself.

Signs of duct problems

Weak airflow from some vents, rooms that stay hot, dust that builds up quickly, or a system that runs a long time to cool the house.

Ducts in a hot attic

Many homes have ducts in the attic. Leaks or crushed ducts there lose cooled air before it reaches the rooms.

What you can check

Make sure vents and returns are open and not blocked by furniture, and that the filter is clean.
