Electrical safety and fire prevention

Avoid extension cords: Only plug your AC directly into a wall outlet. Using an extension cord or power strip can cause the cord to overheat and start a fire.

  • Check for damage: Regularly inspect the AC’s power cords and plugs for signs of fraying, damage, or breakage.
  • Clear the area: Keep the AC unit, both indoor and outdoor, free of obstructions like flammable items, foliage, and other debris to ensure proper airflow and prevent overheating.
  • Install a voltage protector: Consider using an automatic voltage protector or stabilizer to protect your unit from voltage fluctuations, which are common in many areas.
  • Check ratings: For window units, ensure the AC is correctly sized for the circuit it’s plugged into. 

 Indoor air quality

  • Change air filters: Routinely change or clean your AC’s air filters to prevent the buildup of dust, mold, and allergens. A clogged filter forces the unit to work harder, reducing efficiency and potentially causing health issues.
  • Prevent mold and mildew: Condensation inside the unit and ductwork can cause mold and mildew to grow. If you notice a musty odor, have a professional inspect the unit and ducts for proper cleaning.
  • Be aware of refrigerants: While modern AC refrigerants are generally non-toxic in small amounts, high concentrations can cause dizziness, headaches, and nausea. If you notice a sweet smell, evacuate the area and contact a professional immediately. 

 Malfunction warning signs

  • Weak or warm airflow: If your AC is blowing weak or warm air, it could indicate a clogged filter, a refrigerant leak, or a problem with the compressor.
  • Unusual noises: Banging, clanking, hissing, or grinding sounds can signal a variety of problems, from a loose part to a failing compressor or a refrigerant leak. A hissing sound is particularly concerning.
  • Leaking water: Pooling water around your unit can result from a clogged drain line or an iced-up evaporator coil, both of which require professional attention.
  • Higher energy bills: A sudden increase in your electricity bill could mean your AC is running inefficiently and working harder than it should. 

 Professional maintenanceTo ensure the safest operation, have a qualified HVAC technician perform a professional inspection and tune-up at least once a year. They can check for potential electrical issues, refrigerant leaks, duct obstructions, and mold growth. Since you were just asking about AC services, do any of these specific safety concerns make you want to book a service?
