What is an Air Conditioner Capacitor?

Vanport Mechanical and Fire Sprinkler provides exceptional air conditioner capacitor services in Vancouver WA.A capacitor is a component within an electrical system that regulates how much and what kind of current is being allowed within a system. In layman’s terms: capacitors control how much electricity, and what type of electricity, is allowed to pass through it. Capacitors are either used to control electricity within a system, or start the system itself.

You probably have several air conditioner capacitors within your system. Most HVAC systems have start capacitors and run capacitors: one to start the system up, and another to keep the system running.

Capacitors store electrical energy as well as regulate it. It is very important to never touch capacitors without discharging electricity first.

How to Tell Your AC Capacitor is Bad

There are a lot of conditions that can cause a bad AC capacitor, including age, damage, and extreme use, but the “Why?” isn’t as important as the “What do I do now?” Here are some signs that you need to call an HVAC professional:

  • Very slow start to air conditioning system
  • The system turns on but the fan does not
  • The fan turns on but there’s no cold air
  • The AC turns on and off without warning

Because the AC capacitor controls the flow of power, if that flow is interrupted by bad AC capacitor wiring, or by a faulty capacitor, your air conditioning will be interrupted too! Every AC system is different, and some have switches that will turn off everything if a malfunctioning capacitor is interfering with your system.

Dual run capacitors can cause simultaneous problems, because they’re designed to help boost the fan and the compressor at the same time. When they go bad, it’s even more apparent, and will most likely shut down your entire system.

Consult an HVAC Professional for an Air Conditioner Capacitor Replacement

The average “lifespan” of an HVAC system is 15-20 years, but there are a lot of components that can go bad before you need to replace the entire unit, including air conditioner capacitors. If you notice your HVAC system isn’t working correctly, contact Vanport Mechanical. We can help diagnose and repair your HVAC system, finding the correct air conditioner capacitor replacement for your home, and replacing it safely.
