An air conditioner is vital in providing comfortable indoor temperatures, especially in hot weather. However, like most appliances, your air conditioning system may wear down over time. A faulty AC can affect airflow from the vents, causing uneven cooling across your home. Additionally, you may incur high energy bills as the unit struggles to function and consumes more energy. Therefore, it's crucial to always watch out for AC system problems and hire a technician to inspect and fix them. Here are some common AC problems.
The AC Won't Turn On
If your AC doesn't turn on, it could be due to various reasons. For instance, your circuit breaker may have tripped because of power surges or overload circuits. On the other hand, faulty components, thermostat issues like low battery, power outages, and clogged filters are other reasons your air conditioning system may fail to turn on or work. Note that while you can fix some of these issues yourself, it's always best to leave them to an AC system repair technician. For instance, you can quickly change the batteries to your thermostat or switch your circuit breaker on. However, fixing broken or faulty parts could be a challenge only an expert should fix.
The Unit Turns On And Off Abruptly
Your unit will turn on and off frequently without completing cooling cycles if there are obstructions in airflow. This may result from airborne contaminants clogging the air filters, restricting airflow. Ultimately, the system will work too hard to draw adequate air for cooling, causing it to overheat. As a result, the limit switch will activate, causing the unit to short cycle once it cools. Alternatively, if you place your thermostat near drafty spots such as windows, it can malfunction. As such, the thermostat will collect the wrong readings on these surfaces and signal your unit to turn on and off abruptly.
The AC Has Bad Odors
Some components could be defective if you notice strange smells when your AC is operating. For example, refrigerant leaks, wiring problems, mold growth, and stagnant water in the drain lines are all notable culprits. You should also be keen to notice strange smells as they can help you diagnose the problem. For instance, musty smells are a typical indicator of mold and mildew growth in the cooling system. On the other hand, burning smells could indicate wiring problems.
The Fan Doesn't Spin
Since the condenser unit is located outdoors, it is vulnerable to damage. For instance, twigs and other debris can find their way inside the fan compartment and bend the fan blades. This results in the fan blades scrapping against the housing, hindering the rotor from spinning. Additionally, water can seep into the outdoor unit, causing the deterioration of motor windings. Ultimately, this will cause the motor to lose torque, leading to the fan not spinning.
AC malfunctions can hinder performance and increase your energy bills. Therefore, you should schedule routine maintenance checks with an AC system repair technician to ensure your system is in good working order.
