Heating and cooling problems can affect comfort, energy use, and system reliability. This guide explains the most important things Bay Area property owners should know.
Start With the Thermostat
Confirm the thermostat is set to cooling, the temperature is below the room temperature, and the fan is set to Auto. A simple setting change can make the system circulate room-temperature air without active cooling.
Check the Air Filter
A severely clogged filter can restrict airflow, reduce cooling performance, and cause the indoor coil to freeze. Replace a dirty filter and allow a frozen system time to thaw before restarting it.
Outdoor Unit Problems
If the indoor fan runs but the outdoor condenser does not, the system may have a tripped breaker, failed capacitor, damaged contactor, or compressor problem. Electrical HVAC work should be handled by a qualified technician.
Low Refrigerant or a Leak
Low refrigerant is usually the result of a leak. Adding refrigerant without locating and repairing the leak does not solve the underlying problem.
When to Call for AC Repair
Schedule service when warm air continues after basic checks, the system freezes repeatedly, breakers trip, or the outdoor unit will not operate.
