What matters for hvac troubleshooting in Fountain Valley
Attic ducts
Ducts in hot attics leak and lose cooling. A crushed or disconnected run often explains one hot room.
Single small returns
Many older homes have one return grille, which starves the system for air and can freeze the coil.
Thermostat placement
A thermostat in a sunny hallway or near a supply vent cycles the system at the wrong times.
