How Long Do AC Capacitors Last in AC Units in Helena, MT, Homes?

A capacitor is an AC unit component that helps start up and sustain the power of the machine. When you first power your air conditioner on, the capacitor transfers electricity from the starting point (capacitor) to the compressor. Without your capacitor, your air conditioner wouldn't work at all.

If you use your air conditioner during peak heat seasons, you're bound to run into a capacitor issue eventually, even with regular maintenance. Given the fact that it's a small electrical part, capacitors are among the most frail air conditioner components. This cylinder-shaped device runs every time you press the power button, storing charge and consistently running power to your compressor to ensure it functions. 

How Long Do AC Capacitors Last?

Your AC capacitor lifespan ranges anywhere from five to 10 years. Typically, you can find your capacitor on the outdoor unit of your air conditioning system, where the piece is exposed to the most wear and tear. Different factors can impact the lifespan of your capacitor.

• Location: In addition to outdoor units, you can find capacitors on indoor AC units as well. Indoor units are subject to less debris, which means their capacitors tend to last longer. Outdoor capacitors are likely to fail sooner.
• Usage: Because your capacitor activates every time you turn the air conditioner on, the more times it cycles, the more worn the part will become over time. If you have a short-cycling air conditioner, your capacitor will wear out more quickly.
• Over-voltage: Your capacitor prevents power surges from impacting your blower motor, compressor, and other parts. Too much voltage can eventually damage the unit.
• Maintenance: If you properly maintain your air conditioner through cleaning and occasional checks, you can expect your capacitor to last close to 10 years. If you leave dust unchecked, it may not have as long of a lifespan.
• Climate: Just like location, how hot or cold it is impacts your capacitor's lifespan. If you live in a hot or humid place (like Helena during July), your capacitor may wear out faster.

Signs Your Capacitor Is Failing in Your Helena Home

If you are wondering about the state of your capacitor, there are plenty of signs you can look out for to determine if yours is failing or not. If you realize that your capacitor isn't working properly, get an HVAC professional in Helena to assess your situation. Without a capacitor, your air conditioner can't function properly and may not be able to work for much longer.

If you're wondering, "How long do AC capacitors last?" and notice any of the signs below, your capacitor is running on borrowed time. Some signs that your capacitor is failing include:

• High bills: If you have a faulty capacitor that uses too much power each time you turn on your air conditioner, you'll notice your energy bills begin to creep up. Monitor your monthly payments to see if there's a curve.
• Random shutdowns: If your air conditioner is short-cycling or randomly shutting off, your capacitor may not be able to keep a charge.
• Lack of cold air: Your capacitor may be failing if your air conditioner doesn't blow any cold air. The capacitor powers your compressor, which is responsible for cooling the air. If it's broken, you'll only get warm or hot air from your vents.
