Your AC Not Cooling? 5 Common Reasons and How to Fix Them During the scorching heat of summer, there is no alternative to an air conditioner to keep your home comfortable. But if your AC suddenly stops blowing cold air in the middle of a hot day, life can become miserable in an instant. Many people cannot figure out where the actual problem lies. Today, we will discuss 5 major reasons behind an AC not working properly and when you should quickly seek help from a professional AC Repairing service. 1. Dirty or Clogged Air Filter If the internal air filter of your AC gets covered in excessive dust and dirt, it blocks the airflow. As a result, the AC cannot cool effectively. • Solution: Clean the filter by washing it yourself every 1–2 months. 2. AC Gas or Refrigerant Leak Many people believe that an AC loses gas simply because it gets old. However, the actual reason for losing gas is a leak somewhere in the pipes. When the gas level drops, the AC blows normal air instead of cold air. • Solution: Do not try to do this yourself. Call a professional technician to check for leaks and get an (AC gas refill). 3. Dirty Condenser Coil (Outdoor Unit) The outdoor unit of our AC accumulates a lot of dust and dirt. When the condenser coil gets dirty, the hot air from inside the room cannot be released outside. • Solution: Get it washed by a professional (AC repair) team at least twice a year. 4. Faulty Thermostat or Sensor The thermostat acts as the brain of the AC, measuring the room temperature to turn the AC on or off. If this malfunctions, the AC cannot understand when to blow cold air. 5. Compressor Failure If you do not hear any sound from the outdoor unit after turning on the AC, or if the fan spins but it does not cool, the problem is likely with the compressor. This is the most expensive part of an AC. Tips: To keep your AC in top condition and avoid major expenses, it is wise to get an AC servicing done by a skilled technician at the beginning of every season.
