What to do while you wait
- Switch the system off at the thermostat rather than lowering the setpoint further.
- Check whether ice has formed on the indoor coil or the refrigerant line, and let it thaw fully.
- Pull the filter and hold it to the light. If you cannot see through it, change it.
- Close blinds on the sun-facing side of the house to slow heat gain while you wait.

Hayward HVAC questions
Do you handle mini split systems in Hayward?
Yes, where a provider covering your ZIP code services them. Mention the brand and whether it is a single head or a multi-zone system when you call, so the operator matches a provider who works on that equipment.
What happens if the breaker keeps tripping?
Leave it off. A breaker tripping on every cycle indicates a genuine electrical fault, commonly a failing compressor drawing locked-rotor current or a shorted fan motor. Resetting it repeatedly risks damage beyond the original fault.
Can someone come out today?
Sometimes. The line is answered 24/7 in ET, but same-day arrival depends on provider participation, your location inside Hayward, technician availability and how heavy demand is that day. The operator tells you the window offered before you commit.
Why is my AC running but not cooling?
The three usual answers are restricted airflow, low refrigerant charge from a leak, or a failed capacitor stopping the compressor from starting. A technician separates them with a static pressure reading and a superheat measurement.
Can I get maintenance rather than a repair?
Yes. Maintenance visits cover coil cleaning, condensate drain clearing, filter replacement and a capacitor check. These are booked rather than dispatched as emergencies, and they typically cost less than a repair call.
