Common HVAC Emergencies We Fix

HVAC emergencies don’t always look the same, but they all have one thing in common: they disrupt your comfort and need attention right away. At Stay Cool Climate Control, our emergency HVAC service team responds quickly to a wide variety of urgent heating and cooling issues, including:

• Blowing Warm Air in Cooling Mode: When your AC runs but doesn’t cool, it could be a refrigerant leak, compressor issue, or blocked airflow.
• No Heat in the Middle of Winter: A furnace or heat pump that suddenly stops producing heat can leave your home or business dangerously cold.
• Frequent Short Cycling: If your system constantly turns on and off, it strains equipment, raises bills, and often points to thermostat or electrical problems.
• Water Pooling Around the Unit: Leaks near your HVAC system can indicate clogged drains, frozen coils, or refrigerant issues that need immediate repair.
• Poor Airflow Throughout the Building: Weak or inconsistent airflow can be caused by failing blowers, clogged filters, or ductwork problems.
• Unresponsive HVAC System: When your system won’t start at all, the cause could be electrical, mechanical, or even thermostat failure.

No matter what the issue looks like, our 24/7 team is equipped to diagnose the problem quickly and provide reliable solutions that restore comfort fast.
