What Qualifies as an HVAC Emergency?

It can be difficult to know if your HVAC problem warrants an emergency call. If you are experiencing any of the following issues, do not hesitate to seek immediate professional help. These signs often indicate a serious problem that could damage your system or endanger your home.

• Total Loss of Heating or Cooling: If your furnace quits during a freezing night or your air conditioner fails during a heatwave, your home can quickly become uninhabitable. This is a clear emergency.
• Suspicious Odors (Gas or Burning): A rotten egg smell near your furnace could indicate a natural gas leak, which is extremely dangerous. A burning or electrical smell from your vents or unit points to an overheating motor or a serious electrical fault.
• Loud, Alarming Noises: While all HVAC systems make some noise, sudden banging, grinding, squealing, or screeching sounds often signal a critical component failure, such as a broken motor bearing or a loose part.
• Electrical Issues: If your HVAC system is constantly tripping the circuit breaker or you notice dimming or flickering lights when it turns on, it’s a sign of a potentially hazardous electrical problem.
• Carbon Monoxide Detector Alarm: If your CO detector goes off, it is a life-threatening emergency. Evacuate your home immediately and call for emergency services before addressing the HVAC system.
• Significant Water Leaks: While minor condensation can be normal, a major water leak or a frozen indoor coil can cause extensive water damage to your property and indicates a serious system malfunction.

What to Do in an HVAC Emergency: A Step-by-Step Guide

In a moment of panic, it’s important to act calmly and safely. Follow these steps before our technician arrives:

• Prioritize Your Safety: If you smell gas, do not touch any electronics, light switches, or your phone inside the house. Evacuate everyone from the property immediately, leave the door open, and call your gas utility company from a safe distance.
• Turn Off the System: If it is safe to do so and you do not suspect a gas leak, shut off your HVAC system at the thermostat. For added safety, you can also turn off the power to the unit at your home’s main circuit breaker panel. This can prevent further damage.
• Perform a Quick Check: Sometimes, a simple issue can be the cause. Check if your thermostat has fresh batteries and is set correctly. You can also look at your air filter; a severely clogged filter can restrict airflow and cause the system to shut down.
• Clear the Area Around the Unit: Ensure there are at least two feet of clear space around your indoor and outdoor HVAC units. This gives our technicians safe and easy access to diagnose and repair the problem.
