A Quick View: How much Does A AC Capacitor Cost

When it comes to the price of communication capacitors, it depends on many factors, such as their type, brand, and specifications. Generally speaking, the price of a regular capacitor is around $10 to $50, and for most household air conditioning systems, replacing it with a new one is not a big deal. But, if it were a high-performance capacitor specifically designed for use in specific devices or commercial systems, the price could be $50 to $150, or even more expensive.

The type of capacitor also has a significant impact on price. For example, running a capacitor that supports continuous operation of the device is priced differently from starting a capacitor, which is specifically designed to provide the additional power required to start the motor. Also, the voltage level and microfarad (µ F) capacity required for your air conditioner will also affect the price.

If you want to buy something cost-effective, compare prices with several local HVAC suppliers, hardware stores, online shopping malls, and so on. Don't forget to confirm if the capacitor matches your air conditioner. Also, quality is more important than price to ensure reliable and long-lasting use.

What Factors should I Consider before Buying An AC Capacitor

After knowing where to ac capacitors, it is important to pay attention to the following key points to take into consideration:

1. Capacitance value (expressed in microfarads μ F)

Capacitors are worth matching with your home's air conditioning or HVAC system. This information is usually included in the manual or written on the original capacitor. Common values include 5 μ F, 7.5 μ F, 35 μ F, or those with dual capacitors, such as 35/5 μ F.

2. Rated voltage

You need to choose a capacitor with the same or higher voltage as your system requirements (such as 370V or 440V). Never use low voltage, it is easy to break. 440V can replace 370V, but not the other way around.

3. Capacitor type

Single operation capacitor: Used for a motor, usually a fan or compressor.

Dual operation capacitor: It supplies power to both the fan motor and the compressor simultaneously. It is common in household air conditioners to have two capacitance values (such as 35/5 μ F).

4. Physical size and shape

Ensure that the capacitor can be placed in the designated installation position. Capacitors come in various shapes, including circular and elliptical ones. Measure the original size accurately.

5. Tolerance level

Capacitors have a tolerance range, usually ± 5% or ± 10% of the nominal capacitance value. Small tolerance, more accurate performance, and more reliable.

6. Working temperature

Check the operating temperature range of the capacitor, which is generally -40 ° C to 85 ° C. It needs to be suitable for the environment there.

7. Durability and brand

Choose capacitors from big brands with good quality (such as Titan Pro, Genteq, Packard).

Find a product with a long lifespan, such as over 10000 hours.

8. Compliance and Security

It is necessary to ensure that the capacitor meets industry standards, such as UL (Underwriters Laboratories) certification, which ensures safety and performance.

9. Price and Value

Don't just focus on cheap products, they may not be durable and have a short lifespan. Buying a mid-range or high-quality capacitor can save money in the long run.

10. Polarity and wiring terminals

Pay attention to the connection of the terminal posts, which should match your home system (for example, the one marked with "C" is the common terminal, "HERM" is for the compressor, and "FAN" is for the fan).

FAQs: Can I Buy An AC Capacitor directly from HVAC Repair Shops
