Failed Parts For Your Comfort Maker

Here’s a list of commonly failed parts in HVAC systems, along with a brief explanation of their roles:

1. Capacitors

• Assist in starting and running motors. They can fail due to heat exposure or age.

2. Compressors

• Responsible for circulating refrigerant through the system. Failures often occur due to overheating or refrigerant issues.

3. Blower Motors

• Drive air movement through ducts. Overuse or dirt accumulation can cause burnout.

4. Contactors

• Control the flow of electricity to the system's components. Wear and tear lead to malfunction.

5. Refrigerant Lines

• Transport refrigerant between components. Leaks can reduce system efficiency.

6. Evaporator Coils

• Absorb heat from indoor air. They can corrode or become clogged over time.

7. Condenser Coils

• Release heat absorbed from indoors. Dirt buildup or damage can reduce efficiency.

8. Thermostats

• Regulate temperature settings. Failures may result from outdated technology or wiring issues.

9. Filters

• Trap dust and debris. Neglected filters restrict airflow and cause other components to fail prematurely.

10. Drain Lines and Pans

• Handle condensation removal. Blockages can lead to water leaks and system shutdowns.

11. Fan Blades

• Move air through the system. They can bend, break, or become imbalanced.

12. Expansion Valves

• Control refrigerant flow. Failure can lead to incorrect cooling or freezing.

13. Pressure Switches

• Ensure safe operation by monitoring refrigerant pressure. Faulty switches can shut the system down.

14. Heat Exchangers (in furnaces)

• Transfer heat to air in heating mode. Cracks can pose safety hazards.

Routine maintenance and inspections can help identify and address these issues before they escalate.
