Why Isn't My AC Cooling Upstairs?
Several factors could be causing your AC to struggle with cooling the upstairs:
Insufficient airflow: Dirty filters, closed vents, or ductwork issues can restrict airflow.
System capacity: Your AC might be undersized for your home, especially if it's an older unit.
Ductwork problems: Leaky or poorly insulated ducts can reduce cooling efficiency.
Insulation issues: Inadequate attic insulation can let heat in, making it harder for the AC to cool the upstairs.
Thermostat settings: Incorrect settings can affect cooling distribution.
To troubleshoot:
Check air filters: Ensure they're clean or replace them if needed.
Inspect vents: Make sure all upstairs vents are open and clear.
Verify thermostat settings: Ensure correct temperature and fan settings.
Consider professional inspection: If the issue persists, an HVAC technician can diagnose the problem accurately.
