The air conditioner is a very important unit to the cooling system. It not only helps maintain cooler temperatures indoors, but it also controls the humidity levels inside your home. When the air conditioner is no longer functioning correctly or at all, there are is a plethora of causes. Today, we at Absolute Plumbing and Mechanical would like to share the most common causes as to what is making the A/C unit malfunction.
What Causes Your Central Air Conditioner Not to Work & More
Central Air Conditioner Breakers & Fuses: To protect the air conditioner unit’s motor or compressor from overheating, the breakers and fuses play a major role. If the motor ceases, the technicians will usually check the breaker first.
Bad AC Capacitors: The motors that power the compressor and fans will not function without the capacitors. To activate the motor, the start capacitor sends it a jolt and to keep the motor running, the capacitor provides a series of jolts. If either capacitor burns out the A/C unit will not run efficiently.
Failing AC Compressor: To carry out heat exchange the compressor applies energy to the refrigerant and propels it through the coils. The air conditioner cannot cool your home if the compressor is not functioning. The compressor will run hot and eventually seize if there is not enough refrigerant, and too much refrigerant will return to the compressor causing failure.
Need to Clean AC Condenser Coils: Due to exposure from the outdoor elements, the condenser coils are located outside with the compressor can become dirty quite easily. They should be cleaned annually with the garden hose, or if you are not comfortable most professionals will offer a cleaning service and it is usually done during the professional maintenance services as well.
AC Contactor Wear: For the compressor, the blower motor, and the condenser fan motor there are contactors. To start the motors and compressor, the contactors make an electrical connection. It may become difficult for electric current to start the motors if there is arcing and pitting on the contactor.
Clogged AC Drain Line: Dirt, dust, and lint easily clogs the drain line. The drain pan will fill up and overfill causing potential water damage to the components and surrounding surfaces.
Dirty Evaporator Coils: With the help of a series of air ducts, the evaporator coils absorb heat in the air and send it back into the house as cold. These coils can corrode, but with cleaning every 3 years, they can last longer.
Not Changing Air Filters: By design, the filters collect the dirt, dust, lint, and debris and when they are clogged, the A/C unit will not work Be sure to follow the manufacturer’s suggestions as to how often to change or clean the filter as some require every month where others are every three months, and other factors contribute to how quickly they become over encumbered.
AC Refrigerant Leaks: Without the right of refrigerant, the air conditioner cannot operate, and it takes a licensed professional to repair the leaks and recharge it to the necessary refrigerant levels.
Thermostat Problems: The thermostat may be the culprit, whether it is as simple as replacing the batteries, adjusting the settings, or possibly the thermostat will need replacing, the thermostat is usually fairly easy to fix.
