The heat of the summer is the worst time for the central air conditioner to break. Working overtime with little to no rest, your air conditioner needs a break, and will take one at the most inopportune times. Fortunately for you, we are here to help get your air conditioner back in working order, and provide some maintenance tips to help you avoid spending the entire summer sweating indoors and out. Here are four replacement parts that are the most common to fail on a central air conditioner and the easiest to replace.
Common Failing Parts
Fan Blade – Check to make sure the fan blade hasn’t come loose from the motor shaft. If the fan blade moves or wiggles on the motor shaft you will need to tighten it or replace the screws. If the fan motor is still making noise than replace the fan blade.
Thermistor – If a thermistor has failed the unit will normally blow cold air only for a short amount of time, or in short bursts and never actually reaching the correct temperature. It can also cause the blower motor to blow the air at a low volume, erratically or not at all.
Contactor - If the air conditioner is not cooling or not turning on at all than you can potentially have a problem with the contactor. The contactor controls the flow of electricity to all the main components of the air conditioner, it is used to cut off or provide power to the compressor, condenser and the motors.
Capacitor - The capacitor resembles a nine-volt battery. It store energy that can either send a jolt to start a motor or keep a motor running. If the air conditioner is making a humming noise but the fan is not running than the capacitor is usually the problem.
Maintenance Tips
Frequently Asked Question
Most central air conditioners that are maintained properly should last between 15 and 20 years. When the cost of repairing the central air conditioning unit exceeds half the cost of replacing the unit, it would be more cost effective to replace the entire system. Newer systems are often more energy efficient and replacing a unit that is over 10 years old would save long term money on energy bills.
