AC Troubleshooting · Article 1 of 25
Quick answer: Your indoor fan can run even when the system is not removing enough heat.
Understanding the issue
Your indoor fan can run even when the system is not removing enough heat. A thermostat setting, restricted filter, blocked outdoor airflow, or an equipment problem can produce similar symptoms. The symptom alone does not identify the failed part.
What homeowners can do
Start with the accessible basics. Confirm the thermostat is in cooling mode and the set temperature is below the room temperature. With the system off, check an easily accessible filter and replace it if needed using the specified size and type. Keep furniture clear of return grilles.
How Francisco’s Cooling & Heating can help
If cooling does not improve, record whether the outdoor unit runs and whether the problem affects every room. Francisco’s Cooling & Heating can evaluate the system and explain the diagnosis before discussing repairs. Refrigerant and electrical checks belong with a trained technician.
