What is an AC Capacitor?

An AC capacitor is an electronic device that is used to store and release electrical energy. It is made up of two or more conductive plates separated by an insulating material. When connected to a power source, the capacitor charges and stores energy in the form of an electric field. This stored energy can then be released when needed, providing a burst of power to the device.

AC capacitors are typically smaller and more efficient than DC capacitors, and they are also less likely to overheat. AC capacitors are used in a variety of electronic devices, including radios, TVs, and computers. They are also used in power supplies and motor control systems. As a result, they are an essential component of many electronic devices.

What Role Does an AC Capacitor Play in Your AC System?

Your AC system has several important parts that work together to keep your home cool and comfortable. One of these parts is the capacitor. The capacitor is a small metal can that is connected to the compressor, fan, and other moving parts of the AC system. Its job is to store electrical energy and then release it when needed to help start the AC system.

Without a properly working capacitor, your AC system may not be able to start at all or may struggle to keep up with demand, leading to longer wait times for cool air. In addition, the capacitor helps to regulate the flow of electricity to the different parts of the AC system. This ensures that each part receives the right amount of power and prevents damage from electrical surges.

For those reasons, the capacitor plays an essential role in ensuring that your AC system runs smoothly and efficiently. If you notice that your AC system is not performing as well as it used to, it may be time to check the capacitor and replace it if necessary. Doing so can help to restore your AC system’s efficiency and prevent further damage down the line.

How to Tell if you Need a New AC Capacitor

The capacitor in your air conditioner is an important part of the AC system, and it can fail over time. If your AC isn’t working properly, it may be due to a failed capacitor. As a result, your AC unit may struggle to start up or may not cool your home as effectively as it once did. If you suspect that your AC capacitor may be failing, there are a few telltale signs to look for.

Clicking or Humming Noise

One of the most common symptoms of a failing AC capacitor is clicking or humming noise coming from the unit. This noise is caused by the electrical current struggling to flow through the capacitor. As the capacitor fails, it becomes increasingly difficult for the current to flow, which can cause the clicking or humming noise.

Burning Smell or Smoke

Another symptom of a failing AC capacitor is a burning smell or smoke coming from the unit. This is caused by the electrical current flowing through the capacitor. As the capacitor fails, it becomes increasingly difficult for the current to flow, which can cause the electrical components to overheat and produce a burning smell or smoke.

Blowing Warm Air

If your AC unit is blowing warm air, it may be due to a failed capacitor. The capacitor helps to regulate the flow of electricity to the different parts of the AC system. If the capacitor is failing, it may not be able to provide enough power to the compressor, which is responsible for cooling the air. As a result, your AC unit may blow warm air.

Difficulty Starting Up

If your AC unit is having difficulty starting up, it may be due to a failed capacitor. The capacitor helps to provide the initial burst of power needed to start the AC system. If the capacitor is failing, it may not be able to provide enough power to provide this burst of energy to start the system. As a result, your AC unit may have difficulty starting.

Frequent Cycling

If your AC unit is cycling on and off more frequently than usual, it may be due to a failed capacitor. The capacitor helps to regulate the flow of electricity to the different parts of the AC system. If the capacitor is failing, it may cause the AC system to cycle on and off more frequently than normal.

Increased Energy Bill

If you notice that your energy bill is increasing, it may be due to a failed capacitor. The capacitor helps to regulate the flow of electricity to the different parts of the AC system. If the capacitor is failing, it may cause the AC system to use more power than usual. That being the case, your capacitor has become less efficient and your energy bill will likely increase.

If you are experiencing any of these symptoms, it is important to check the capacitor and replace it if necessary. Doing so can help to restore your AC system’s efficiency and prevent further damage down the line.

What Causes an AC Capacitor to Fail?

Over time, capacitors can fail due to several factors, such as old age, excessive heat, or a power surge. When a capacitor fails, it can cause the air conditioner to shut down or work less efficiently.

It is important to be aware of the signs of a failing capacitor, such as a clicking noise from the AC unit, strange smells, or unusual flickering lights. If you notice any of these symptoms, it is important to contact a qualified technician as soon as possible to have the issue diagnosed and repaired. By doing so, you can help to ensure that your AC unit continues to run smoothly for years to come.

Different Types of Capacitors

Not all capacitors are created equal. Several different types of capacitors are used in air conditioning units, each of which serves a different purpose.

Start Capacitor

  • The most common type of capacitor is the start capacitor, which helps to provide the initial burst of energy needed to start the AC unit. For the part alone, it will typically run anywhere between $9 and $25. Higher end models on the other hand can get quite pricey at around $180. Let’s not forget that an HVAC contractors will also charge for labor. The labor costs could be as little as $84, or as high as $380.

Run Capacitor

  • The run capacitor, on the other hand, helps to keep the AC unit running once it has been started. Generally this part will cost around $6 and $30, and with labor anywhere from $81 to $230.

Dual Run Capacitor

  • The dual run capacitor, combines the functions of both the start and run capacitors into one unit. Depending on brand and voltage this part will run anywhere from $15 to $45 or $90 to $250 fully installed.

Blower Capacitor

  • The blower capacitor helps power the blower motor. For this part, it will set you back anywhere from $9 to $12. If you factor in the labor to have this part installed then the price will increase significantly and will cost anywhere from $75 to $200.

Heat Pump Capacitor

  • Finally, there is the heat pump capacitor, which helps to power the heat pump in an AC unit. The replacement part will cost you $15 to $25 and with labor you should plan to add an additional $75 to $200.

If you are unsure of which type of capacitor your AC unit uses, it is important to consult with a qualified technician. Attempting to replace the wrong type of capacitor can cause further damage to your AC unit and void your warranty.

Calculating AC Capacitor Cost

The cost of replacing an AC capacitor varies depending on a few factors. These factors include the type of capacitor, the brand, the size, the warranty, the voltage, and the specific needs of the customer. The most common way to calculate the cost without a professional is to take the square footage of your home and multiply it by the number of BTUs your system uses. This gives you a base price for the capacitor.

However, there are other factors to consider when calculating the cost of your capacitor:

  • Size of the unit. The larger the unit, the more it will cost.
  • Efficiency/Voltage of the unit. The higher the efficiency, the more it will cost.
  • Brand of the unit. The more popular brands will usually cost more.
  • Warranty on the unit. The longer the warranty, the more it will cost.

All of these factors should be considered when calculating the cost of your air conditioner capacitor. HomeAdvisor also has a great blog regarding different types of AC capacitors and their cost.
