Parts of your air conditioner can fail for a number of reasons, without warning. This can negatively impact your home’s temperature and your family’s level of comfort. Oftentimes, your air conditioner even malfunctions when you need it the most.

By knowing which AC parts get damaged easily, you’re two steps ahead of costly repairs and unexpected breakdowns.
Common Air Conditioner Parts that Are Prone to Break
- Condenser coils
Condenser coils are comprised of tubes filled with refrigerant liquid.
Accumulated dirt and debris may clog the coils in your system, and put unnecessary strain on both your air conditioner and furnace to work harder.
The coil’s inner or outlet lining may also break down over time due to corrosion. Refrigerant leaks often follow when this happens.
Cleaning the coils on a regular basis will improve your HVAC system’s efficiency.
- Thermostat
A thermostat displays the current indoor temperature, turning your system on and off accordingly.
However, a faulty thermostat doesn’t send the correct signals to your system, so your home wouldn’t be at the temperature you desire.
Recalibrating it or installing a new thermostat will fix the issue.
- Refrigerant
The cooling agent that’s contained in the coils of your AC, the refrigerant absorbs heat and leaves cooler air as it passes through compressors and evaporators.
Normal wear and tear on the unit, as well as pinhole leaks affecting copper coils, may cause the refrigerant to leak.
Signs your AC is low on refrigerant usually include poor cooling performance, ice on the evaporator coil, unreasonably high energy costs, and hissing or bubbling noises coming from the air conditioner.
- Capacitors
Capacitors help power your unit’s compressor, as well as its blower motor and the outside fan. Capacitors fail over time due to excessive use.
Electrical issues can develop with your air conditioner, including problems with wiring and capacitors. These are serious fire hazards.
- Fan motor/ blower motor
Since the fans are always running, they often face obstruction and may require oiling on the hinges down the road. The motor may also burn due to excessive use. The buildup of dust, dirt, and debris may burn up the windings and bearings more quickly, too.
If the fan motor or blower motor breaks down, your AC will stop blowing cold air.
