Quick answer: A few basic observations can make your service call more productive.
Understanding the issue
A few basic observations can make your service call more productive. They do not require opening equipment or diagnosing an electrical fault. Start with the thermostat and accessible airflow paths.
What homeowners can do
Confirm cooling mode and the requested temperature. Check batteries if your thermostat uses them. Look for a blocked return grille or a dirty, easily accessible filter. Note any fault message, visible ice, or water. If a breaker has tripped repeatedly, leave the system off rather than resetting it again.
How Francisco’s Cooling & Heating can help
When you contact Francisco’s Cooling & Heating, share the symptoms and what you checked. We can use that information during the evaluation. A working display does not establish that the entire system has power, and a spinning fan does not prove the compressor is working.
