Aircon not cooling upstairs
Upstairs rooms can be harder to cool because heat load, zoning, insulation and airflow all work against the system.
Why upstairs rooms struggle
- Upper levels collect more heat, especially in bedrooms and west-facing rooms.
- Zoning, insulation, duct condition and return air can all affect upstairs comfort.
- A system that worked in mild weather can still struggle once heat load increases.
Helpful details to send
List the rooms affected, whether downstairs is comfortable, the system type, zoning setup and when the upstairs area is worst.

Can servicing improve upstairs airflow?
Servicing can help identify airflow restrictions, dirty filters, return air issues and zoning problems that affect upstairs cooling.
