This article will discuss five common reasons why your air conditioner may have stopped working and what you can do about it.

  1. Dirty Air Filters
    The first reason your air conditioner may have stopped working is dirty air filters. Air filters trap dirt, dust, and other particles from entering the system, so keeping them clean is essential. If you haven’t changed your air filters in a while, they may have become clogged, causing your air conditioner to overwork. This can result in decreased efficiency, reduced airflow, and even complete system failure. To prevent this, change your air filters regularly, at least once a month.

  2. Refrigerant Leaks
    Another common reason for a broken air conditioner is refrigerant leaks. Your air conditioner relies on a specific amount of refrigerant to cool the air in your home. A leak in the system decreases the refrigerant level, making it difficult for the air conditioner to do its job. If you suspect a refrigerant leak, you must immediately call a professional like Air Doctorx Heating and Air Conditioning. If you live far away and are unsure of a professional HVAC company, search “AC Repair Near Me” online.

  3. Malfunctioning Compressor
    The compressor plays a crucial role in your air conditioner’s functioning. Common signs of a malfunctioning compressor include a loud humming noise, a hissing sound, or no cold air from the vents. If you’re experiencing any of these symptoms, it’s time to call the professionals at Air Doctorx Heating and Air Conditioning to diagnose the issue and perform the necessary repairs. 

  4. Damaged Ductwork
    Ductwork plays a crucial role in your air conditioner’s performance; if it’s damaged, it can cause many problems. Poor airflow, uneven cooling, and high energy bills are all signs of damaged ductwork. If you suspect a problem with your ductwork, it’s crucial to have a professional perform a thorough inspection and make the necessary repairs to keep your air conditioner running smoothly.

    Electrical problems can cause your air conditioner to stop working. Issues such as a blown fuse, tripped circuit breaker, or damaged wiring can prevent your air conditioner from functioning correctly. If you suspect electrical problems, it’s best to leave the repair to our professional.
