5 Telltale Signs Of An Air Conditioner Not Working Properly

An efficiently functioning air conditioner is essential for our comfort and well-being during peak summer months. However, just like any other mechanical system, air conditioners can experience issues from time to time. Identifying the early warning signs of a malfunctioning air conditioner can save you from costly repairs and ensure uninterrupted cool air during the hottest days.

This article will discuss five telltale signs indicating that your air conditioner may not work properly. Contact Thomson Air Conditioning today if you already need AC repair in Cerritos, CA, and surrounding areas. Our experienced AC technicians will inspect the faulty AC deeply and take the necessary steps to fix it.

Let's check out 5 major faulty air conditioner signs

  • Insufficient Cooling: If your air conditioner fails to cool your home adequately or if you notice uneven cooling throughout different areas, it may indicate a problem with the system. Issues such as a malfunctioning compressor, low refrigerant levels, or a faulty thermostat could be to blame.
  • Weak Airflow: Poor airflow from your air vents can be a sign of a blockage in the ductwork, a clogged filter, or a failing blower motor. Reduced airflow not only affects comfort but also reduces the overall efficiency of your air conditioning system.
  • Strange Noises: Unusual sounds such as grinding, rattling, or squealing from your air conditioner could indicate worn-out or loose components. Ignoring these noises may lead to further damage and expensive repairs down the line.
  • Frequent Cycling On and Off: If your air conditioner frequently turns on and off without effectively cooling your home, it may be short-cycling. Various factors, including an oversized unit, a malfunctioning thermostat, or a refrigerant leak, can cause short cycling.
  • High Energy Bills: A sudden spike in your energy bills without a significant change in usage patterns could indicate an inefficient air conditioning system. Aging equipment, poor insulation, or duct leaks can increase energy consumption and costs.
