Urgent AC Issues
When to call for emergency AC service.
Real Deal HVAC explains what is happening and gives you the practical next step.
Frozen Coil
Turn cooling off and call. A frozen coil needs diagnosis before the system is pushed harder.
Water Leaks
Leaks can involve frozen coils, drain problems, condensate pans, or airflow issues.
Electrical Symptoms
No start, buzzing, tripped breakers, fan motor issues, and capacitor concerns should be checked by a technician.
Urgent Occupants
Families, seniors, tenants, and businesses may need faster triage when indoor temperatures climb.
Repair vs Replacement
If the emergency repair is major, Real Deal HVAC can explain whether replacement should be considered.
Book nowBefore Calling
Quick checks that can help the service call.
Do not take apart equipment. These simple checks help describe the issue and may reveal a basic setup problem.
- Confirm the thermostat is set to cooling and the temperature is below room temperature
- Check whether the air filter is extremely dirty or blocked
- Look for ice on the indoor/outdoor lines or coil area and turn cooling off if frozen
- Check whether the breaker has tripped once; do not keep resetting a breaker that trips again
- Keep the outdoor unit clear of obvious airflow blockage and call if the unit is not starting
