1. Thermostats: Over time, thermostats can become less accurate and may need to be replaced. This can be due to a variety of factors, such as wear and tear, damage from power surges, or simply age.
2. Circuit boards: Circuit boards control various functions of a heating system, such as the blower motor, gas valve, and thermostat. They can become damaged due to power surges, overheating, or simply age.
3. Blower motors: Blower motors circulate warm air throughout a home. They can wear out over time or become damaged due to dust and dirt buildup.
4. Gas valves: Gas valves control the flow of gas to the heating system's burners. They can become clogged with dirt or debris, which can prevent them from operating properly.
5. Igniters: Igniters create a spark that ignites the gas in the heating system's burners. They can wear out over time or become damaged due to dirt or corrosion.
6. Heat exchangers: Heat exchangers transfer heat from the heating system's burners to the air circulating through the system. They can become damaged due to corrosion or overheating.
7. Capacitors: Capacitors store electrical energy and help to start the heating system's compressor. They can wear out over time and need to be replaced.
8. Contactors: Contactors are electrical switches that control the flow of power to the heating system's compressor. They can wear out over time or become damaged due to corrosion or overheating.
9. Filters: Filters remove dirt and dust from the air circulating through the heating system. They need to be replaced regularly to maintain the efficiency of the system.
10. Ducts: Ducts distribute warm air throughout a home. They can become damaged due to wear and tear, insect infestation, or moisture buildup.
