What To Do When Your AC Won’t Turn On

forzWhen your air conditioning won’t turn on, panic tends to set in. The temperature outside is rising, and so is the discomfort level in your home. There could be a number of reasons for this problem, the most common being electrical fault, thermostat problems, or your system being frosted over. Read on to discover what to do when your air conditioner won’t turn on.

AC System Coils are Frozen

Air conditioners work by moving warm air over a coil of cool air, also known as the evaporator coil. If your air conditioner won’t turn on and your system is frosted over, it may be because the air is moving too slowly over the evaporator coil, thereby causing a backup of moisture. This can cause the evaporator coil to freeze over, which will not allow the unit to properly cool your home. Causes of this problem include low coolant fluid or dirty internal machinery. If there is a low level of coolant, your system may have a leak and need to be looked at by a professional. In any case, your air conditioning system should be examined annually to avoid such problems as the evaporator coil freezing over.

Wiring or Breaker Problem

Problems with the internal wiring of your home air conditioning unit, or the wiring that runs from the air conditioning unit to your home, are often the cause of a faulty HVAC system. Deciphering whether the problem is internal or external is simple enough to assess. Make sure to check your home power box breakers and surrounding outlets to see if the problem lies within the air conditioner or other external components of the system. Other electrical problems that can occur within the system include worn compressors and fans and wire corrosion. These issues are caused when the air conditioning system runs too frequently.

Thermostat is Malfunctioning

The thermostat on an air conditioning system reads the temperature of the air entering the evaporative coil, and is the ultimate judge of the temperature in your home. When your air conditioner won’t turn on, there may be an issue with the thermostat. This problem can be something as simple as the sensor being knocked out of place, causing it to misread temperature, or something more serious, if the sensor is completely detached from the system. If your air conditioner won’t turn on, check to make sure the temperature sensor is near the evaporator coil, and not connected to or completely removed from it. More often than not, you can solve this issue yourself by simply adjusting the wire holding the sensor.

Air conditioning units play a vital role in providing you comfort in your home, especially during the hot Florida Summer months. If you are experiencing issues, a frozen system, breaker issues, or faulty thermostat are just a few of the many reasons your unit will not turn on.
