These Common HVAC Replacement Parts Often Need Attention

Your HVAC system is complex machinery consisting of various parts, each having its own life span. Some components tend to require replacement sooner than the rest. Here’s more on the common HVAC replacement parts that tend to need attention over the course of your HVAC system’s life.


The start-and-run capacitors allow your HVAC system to come on and operate. These electrical components are heavily used, so they’re one of the most likely HVAC replacement parts to be prone to wear and tear. As a result, you’ll likely have to replace them several times during the useful life of your HVAC system.

Fan Motor

Thanks to Yuma’s hot climate, the fans in your air conditioner get a grueling workout. It comes as no surprise that the fan motors can burn out because of extreme use.

Air Filters

Air filters trap dirt and dust particles in the air that’s traveling through your HVAC system, helping make your home’s air cleaner. If they’re the disposable type, they get dirty after some time and require replacement. Dirty filters restrict airflow through your system, making it run inefficiently.

You should replace your air filters at least six times a year. If you have pets or family members with chronic respiratory conditions, you should consider this one of the HVAC replacement parts that is a high priority and change your filters more frequently.

Evaporator Coil

The evaporator coil contains refrigerant. It absorbs heat from your home’s air. When the air touches the cold coil, condensation occurs. Dust and dirt often accumulate on damp coils and lower their effectiveness. The condensation can also lead to mold growth. Corrosion can also damage the coil and result in small pinholes, which allow the refrigerant to leak. Problems with the evaporator coil are not readily noticeable to homeowners.


The compressor manages a heavy workload, pumping refrigerant between the condenser and evaporator coils in a closed loop. It can fail and require replacement due to:

  • Dirty coils
  • Low refrigerant levels
  • Clogged refrigerant lines

The compressor is the most expensive AC component. Fortunately, you can avoid having to replace it through regular AC maintenance.

Keep in mind that regularly carrying out HVAC maintenance checks will significantly reduce the problems that develop, helping components last longer.
