Even though you take good care of your heating and cooling system, various components will eventually fail. When you know which HVAC parts are most likely to fail sooner, you can budget for them in advance. The following overview can prepare you for the most common breakdowns so that you can plan to avoid long periods with an inoperable system.

4 HVAC Components That Will Breakdown First

1. Air Filters

Although they’re probably the least expensive of the various HVAC parts you’ll have to replace, your system’s air filter should be checked once per month. Leaving a dirty filter in place will force your system to work harder to provide the same level of comfort. This can lead to other components burning out while driving up your energy consumption. Additionally, failing to replace a filter will cause your system to push contaminants, such as dust and pollen, back out into your home.

2. Motors, Fans, and Wiring

The main motor is responsible for operating the entire cooling system. As such, the AC parts that comprise the motor are in constant use anytime the system is in use, causing extensive wear and tear over time. Most problems that require the expertise of a contractor are the result of a failure in the motor. HVAC motors are designed to last for a long time, but you should be prepared to replace your system’s motor at least once.

3. Compressor 

The evaporator coils inside the compressor can become dirty, forcing it to work harder. This is one way that the unit’s temperature will rise, making it harder for the unit to cool the air. Alternatively, the refrigerant line may become blocked with ice, which can also prevent the compressor from functioning efficiently.

Either of these issues can cause the compressor to burn itself out. If your system seems to be producing air that hasn’t been properly cooled, or if you notice ice forming on your AC unit, there may be a problem with your compressor.

4. Fan Motors

Your fans, or blowers, also have motors that can fail. Although this type of failure is rare, it can happen from time to time through regular wear and tear. The best way to prepare for this type of problem is to request a seasonal tune-up of your system and to ask your technician to check your fan motors. This will help you prepare for the added expense of replacing them if they fail during the summer months.
