• Complete Loss of Heating or Cooling: When your furnace fails to provide heat in the dead of winter or your air conditioner stops cooling during a heatwave, it’s an emergency. This can lead to discomfort, potential health risks (hypothermia or heatstroke), and even frozen pipes in winter.
• Unusual Noises: Loud banging, screeching, grinding, or whistling sounds coming from your HVAC unit often indicate a serious problem. These noises can signal mechanical failures, loose components, or obstructed airflow.
• Foul Odors: Strange smells, such as burning plastic, musty odors, or gas leaks, should be treated as emergencies. Burning smells can indicate electrical problems or overheating components, while musty odors may point to mold or mildew growth. Gas leaks pose a serious health and safety hazard.
• Water Leaks: Water leaking from your HVAC unit can cause significant damage to your property, including mold growth, structural damage, and electrical hazards.
• Electrical Issues: Tripped circuit breakers, flickering lights, or the smell of burning electrical components are signs of electrical problems that require immediate attention.
• Poor Air Quality: If you notice excessive dust, mold spores, or other contaminants in the air, it could indicate a problem with your air filters, ductwork, or overall system performance.
