7 Vital Parts That Help Prevent AC Breakdowns

It’s necessary to understand the different components of your air conditioner to prevent inopportune breakdowns. You can better maintain your system by understanding the different components of an HVAC system. Moreover, it’s recommended that you only have a trained and licensed professional in the Bay Area attempt the servicing and repairing of an air conditioner.

1. Air Filters

Air filters are the most important yet the most overlooked component of an air conditioning system. Blocked air filters can affect other components of the AC since its main function is to prevent dust and debris from circulating through the system. Dirty air filters make the fan consume more electricity for moving air.

2. AC Belts

Belts in an air conditioner can experience considerable wear and tear over time. This can cause the system to stop working. You should replace and change the belts in a timely manner to keep the system running efficiently. A worn slipping belt results in money wastage because of extra energy consumption.

3. Capacitors

Capacitors are required for the general working of a heating and cooling system. However, not all capacitors are created equal. The size of the capacitor is determined by the size of the motor. Capacitors are responsible for providing starting torque and improving the running efficiency of a motor. They are necessary for the proper functioning of any HVAC system. Low-quality capacitor may damage the operating function of the motor or cause it to stop working entirely.

4. Evaporator and Condenser Coil

You need to keep the condenser coil clean. Dirt buildup is inevitable in evaporator and condenser coils. Condenser coils are responsible for ejecting accumulated heat while evaporator coils extract heat and humidity from the indoor space. the buildup may contain dust, dirt, grease, bacteria, and mold. Excessive blockage may compel the condenser coil to work harder. It may prevent the system from operating at optimum efficiency as well. The coils should be cleaned at least once a year for proper working.

5. Contactors

You need a reliable contactor for increasing your AC unit’s life span. Contactors control the amount of electricity delivered. It also ensures the electricity is delivered to only those parts that need it. Compression damages that are not taken care of quickly can cause contactor failures. With that said, this is not a repair you should undertake on your own. Contactor replacement requires working with high-voltage. You should consider seeking a trusted contractor for assistance.

6. Fuses

Fuses in an AC unit can blow suddenly during a malfunction. You should replace them in a timely manner. Fuses are present throughout the air conditioning system, such as in the motors, evaporator coils, compressors, and wiring configurations. Fuses protect the components from overloading and overheating. Each component in an AC prevents another part from failing. Hence, if you don’t replace the fuses as necessary, other parts of the AC will begin breaking down as well.

7. Fan Motor

Fan motor is also known as the heart of an air conditioner. They ensure the system is working as intended. Fan motor allows the AC to circulate air throughout the indoor space. You should not overlook maintenance issues since these components work under tough conditions. Neglecting the motor shaft and bearings can impact the comfort of the occupants.
