If your AC suddenly stops working, starts making loud noises, leaks water or refrigerant, or gives off burning smells, it’s time to call for emergency AC repair. These issues can damage your system or pose safety risks, especially during hot Massachusetts summers. This guide breaks down the warning signs, what counts as a true emergency, and how to get fast, reliable help when you need it most.
Understanding Emergency AC Repair
Emergency AC repair addresses system failures that threaten safety or comfort. Examples include refrigerant leaks that emit harmful gases or electrical malfunctions that risk fire. Unlike routine maintenance, like filter changes, emergencies require prompt professional attention. Recognizing these urgent scenarios is the first step to restoring reliable cooling.
Common Signs Requiring Emergency AC Repair
Several clear indicators suggest an immediate call to an HVAC technician:
- Complete loss of cooling
- Loud grinding, banging, or screeching noises
- Visible refrigerant or water leaks around the unit
- Burning or electrical odors coming from vents
- Frozen evaporator coils or condensate pan overflow
- Rapid on/off cycling (short cycling)
Each symptom points to a critical issue with components such as the compressor, condenser coil, thermostat, or air handler.
