When you turn on your AC, you expect your system to serve you when you need it. But sometimes, you might try to turn on your unit, but it just won't budge.
A broken air conditioner can make your living or office space uncomfortable. You might get confused if you don't know what the problem is. This article highlights four common reasons why your air conditioner won't turn on.
1. Clogged Air Filter
Your air conditioning unit works to absorb the humidity from the air blown into your home. This moisture condenses to form tiny water droplets, which drip into a condensation tray. The water collected is subsequently released through the drain line.
However, if your air filters are clogged, there won't be sufficient airflow. As a result, the water droplets will freeze on your coils rather than drip into the condensation tray. Excessive freezing eventually prevents your unit from turning on. To solve this problem, you need to replace or clean your air filter monthly, depending on the season or number of people in your home.
2. Thermostat Issues
Your thermostat is among the main components of your AC unit. So if this device has a problem, your air conditioner won't accurately regulate the temperatures in your home as you'd expect. The inaccurate readings might trigger your unit to turn off immediately after you power it or fail to turn on at all.
Your thermostat may fail due to several issues. First, the batteries might be dead, and you may need to replace them to rule out this problem. However, if you replace the batteries and your system still doesn't turn on, the thermostat might have a serious wiring problem. Therefore, you need to call a professional to diagnose and figure out the best solution.
3. Tripped Circuit Breaker
Your circuit breaker protects your system from damage by high electrical voltage. However, your breaker may trip when you use too many electrical appliances at once. Unfortunately, your AC won't turn on if this happens.
If your circuit breaker trips, try to turn the switch on from the supply mains. However, if it continues to trip repeatedly, turn the main switch off immediately and call an expert for further diagnosis.
4. Refrigerant Leaks
Your unit's refrigerant is crucial in cooling your home. It draws heat from the atmosphere to lower indoor temperatures. However, if your refrigerant coils develop holes, the refrigerant fluid will start to leak. With low refrigerant levels, your AC system won't turn on.
Leaking refrigerant is toxic and might corrode other components of your AC unit. Therefore, you need to call local AC services to check and replace the damaged coils. They can also refill the refrigerant to the required levels during their visit to get your unit back to normal operation.Share
