How Long Do AC Capacitors Last in Princeton, NJ?

When you understand some of the parts that make your HVAC system run, you know more about identifying potential problems and what causes them. The capacitor, for example, plays a crucial role in making your air conditioner run. 

How long do AC capacitors last? What might a capacitor failure look like? As your trusted provider of AC services in Princeton, NJ, Dustin’s Plumbing Heating and A/C Repair explains what you should know about this essential HVAC component. 

What Does the Air Conditioning Capacitor Do?

Air conditioner capacitors collect and store electrical energy to power upcoming cooling cycles. When your air conditioner completes a cooling cycle, the capacitor gathers power. Once the temperature rises enough to trigger the next cycle, the cooling system uses the stored energy to start back up. 

Considering their crucial role, how long do AC capacitors last? Capacitor replacement isn’t a very common service. Typically, it lasts throughout the cooling unit’s service life. 

Unfortunately, several factors that impact the capacitor’s performance can strain it over time and cause its downfall. Without a working capacitor, your air conditioner can’t start up, so it’s important to recognize when there’s a problem.

How Long Do AC Capacitors Usually Last?

Air conditioning capacitors usually last between ten and 20 years. Replacing your capacitor is usually a warning that your air conditioner itself is nearing the end. Watch for these signs of bad capacitor performance:

• Your air conditioner doesn’t turn on with the thermostat signals. It might not get the power needed to begin cooling. 
• Your air conditioner suddenly stops cycling without reaching your temperature settings. It lacks the electricity to sustain a full cycle. 
• You’re paying substantially more to cover your electricity bills. Bank-breaking utility costs are another indication that your air conditioner’s capacitor is on the fritz. 
• You can hear loud humming sounds coming from your indoor unit. HVAC systems should emit only a soft hum that fades into the background.

How long do AC capacitors usually last? To answer that, let’s see what factors shorten the AC capacitor lifespan.

What Shortens or Lengthens an Air Conditioner Capacitor’s Useful Life?

Factors that dictate the capacitor’s longevity may also impact the air conditioner as a whole. It might force you to purchase an expensive new capacitor if your HVAC system has years to go, so wear and tear prevention pays.

HVAC Maintenance

Air conditioner maintenance keeps each component in good working condition throughout the system’s lifespan. HVAC technicians clean coils, test electricity usage, and top off low refrigerant during the average tune-up in Princeton, New Jersey, and each task protects the capacitor from undue strain. 

Component Quality

Some capacitors are more solid than others. A cooling system component from a trusted brand with a reputation for producing quality products will likely last longer than a cheap one. For capacitors and air conditioners, quality equals savings.

Use Habits

At what setting do you keep your thermostat? If you prefer a low temperature, you increase the demands on your cooling system, which impacts HVAC system efficiency and erodes the capacitor’s lifespan much faster. A warmer temperature could slow the unit’s wear and tear. 

External Stressors

How long do AC capacitors last? If you frequently deal with breaker trips, power surges, and other electrical issues, you’re more likely to face an electrical component failure, even if the rest of your system purrs. Consider a surge protector or have an electrician inspect your breaker box for potential problems. 

How Does the Climate in Princeton, New Jersey, Influence Service Life for Air Conditioning Components?

Climate is another factor in your AC capacitor’s lifespan. Princeton, New Jersey, has a moderate cold season that lasts around six months. The warm season brings lots of humidity and temperatures that reach the high 80s, so from June to September, many residents use their air conditioning systems more frequently. 

Your use depends on your comfort preferences, but the lower you set your thermostat, the more wear and tear your air conditioner’s capacitor accrues. Summers in Princeton, New Jersey, don’t usually reach the 90s, and the rain cools the atmosphere. If you’re maintaining it well and cooling at reasonable temperatures, our local climate shouldn’t have a significant impact on your capacitor’s lifespan.
