When your HVAC system suddenly stops working, it can be stressful—especially in extreme weather conditions. Whether it’s a freezing winter night or a scorching summer afternoon, knowing what to do can help you stay safe and get your system up and running as quickly as possible. Here’s a step-by-step guide to handling an HVAC emergency.

1. Check the Basics

Before calling for emergency repairs, take a moment to check for simple issues:

• Thermostat Settings – Ensure your thermostat is set to the correct mode (heat or cool) and the temperature is properly adjusted.
• Power Supply – Check if a circuit breaker has tripped or if there’s a power outage affecting your home.
• Air Filter – A clogged filter can restrict airflow and cause your system to shut down.
• Vents and Registers – Make sure all vents are open and unblocked to allow proper air circulation.
• Outdoor Unit – If you have an outdoor AC unit, check for debris, ice buildup, or obstructions that could be preventing it from working efficiently.

2. Turn Off Your System If It’s Malfunctioning

If your HVAC unit is making unusual noises, emitting strange smells, or short-cycling (turning on and off rapidly), turn it off immediately. This can prevent further damage and reduce safety risks. Running a faulty system can lead to bigger and costlier issues down the line.

4. Stay Safe While Waiting for Repairs

If your HVAC system fails during extreme temperatures, take precautions to stay comfortable and safe:

• In the Heat:
  • Use fans to improve air circulation.
  • Stay hydrated and avoid strenuous activities.
  • Close blinds and curtains to block out heat from the sun.
  • If possible, spend time in an air-conditioned public space like a mall or library.
• In the Cold:
  • Bundle up in warm clothing and use extra blankets.
  • Close off unused rooms to preserve heat in occupied spaces.
  • Use space heaters safely—keep them away from flammable materials and never leave them unattended.
  • If the cold becomes dangerous, consider staying with a friend or checking into a hotel until repairs are complete.

5. Understand Common HVAC Emergency Issues

HVAC emergencies can arise from various causes, including:

• Refrigerant Leaks – A lack of refrigerant can prevent your AC from cooling properly and may lead to serious compressor damage.
• Frozen Evaporator Coils – Restricted airflow or low refrigerant levels can cause ice buildup on your evaporator coils, stopping your AC from working.
• Electrical Issues – Faulty wiring or a blown fuse can lead to system shutdowns and potential safety hazards.
• Ignition or Pilot Light Failure – Gas furnaces may fail to ignite due to a malfunctioning igniter, thermocouple, or pilot light issues.
• Clogged Drain Lines – AC units have drain lines that remove condensation. When these get clogged, water can back up, causing system failure or even water damage. 

6. Prevent Future Emergencies

Routine maintenance is key to preventing HVAC emergencies. Here are some proactive steps you can take:

• Schedule Regular Tune-Ups – Have a professional inspect and service your system at least twice a year—once before summer and once before winter.
• Replace Air Filters Frequently – Dirty filters can restrict airflow and put unnecessary strain on your system. Change them every 1-3 months.
• Keep Your System Clean – Clear debris from around your outdoor unit and ensure vents inside your home remain unobstructed.
• Monitor Energy Bills – A sudden spike in energy costs could indicate your HVAC system is struggling and may need servicing.
• Upgrade an Aging System – If your unit is more than 10-15 years old and frequently breaks down, consider replacing it with a newer, energy-efficient model.
