When HVAC Issues Are Emergencies
Some heating and cooling problems can wait a day. Others can’t. In Charleston’s humid subtropical climate, indoor temperatures rise fast when cooling fails, and a heat pump that stops working loses both heating and cooling capability at once, making it one of the most urgent emergencies a homeowner can face.
Loss of cooling during peak heat is a genuine health risk, especially for young children, elderly family members, or pets. No heat during a cold snap carries the same urgency for vulnerable household members. Electrical burning smells, smoke, or visible sparks near your equipment are always cause to shut the system down immediately. Water leaking from the indoor unit onto ceilings, walls, or floors can cause serious property damage if left unaddressed.
Before you call, two safe checks are worth trying: confirm your thermostat has power and verify that breakers haven’t tripped. If everything looks normal but the system still won’t start, or if anything smells or sounds unsafe, stop troubleshooting and call for emergency HVAC service.
Common signs you should call for emergency HVAC service include:
- No air at all from vents during extreme heat or cold
- Loud banging, screeching, or grinding noises from the unit
- Electrical burning smells, smoke, or scorch marks near equipment
- Water leaking from the indoor unit onto ceilings, walls, or floors
- System short cycling: turning on and off repeatedly without reaching the set temperature
Short cycling can point to thermostat problems, a failing capacitor, control board issues, or a refrigerant leak, and it typically worsens over time if not addressed. If you’re unsure whether your situation qualifies as an emergency, call us. A quick conversation lets us assess what you’re seeing and guide you toward the safest next step.
