Why AC Unit Capacitor 45/5 is necessary?

I have been working as an HVAC technician for over a decade now, and during this time, I have come across numerous AC unit problems. One of the most common issues that I have encountered is a faulty capacitor. And in most cases, the recommended replacement is a 45/5 capacitor.

Firstly, let’s understand what a capacitor does in an AC unit. It acts as a temporary power storage device for the compressor and fan motors. When the AC unit is turned on, the capacitor gives a boost of energy to start these motors, and then it helps maintain a steady flow of electricity to keep them running smoothly.

Now, why specifically 45/5 capacitors? Well, this size refers to the capacitance or storage capacity of the capacitor. The first number (45) represents the capacitance for the compressor motor, while the second number (5) indicates the capacitance for the fan motor. These two motors have different power requirements, and therefore they need separate capacitors with different capacitance levels.

In my experience, using an incorrect size or lower quality capacitor can lead to frequent breakdowns and decreased efficiency of the AC unit. This not only results in higher repair

My Buying Guide on ‘Ac Unit Capacitor 45/5’

As an experienced HVAC technician, I understand the importance of having a reliable and efficient AC unit. One crucial component of an AC unit is the capacitor, which helps start and run the compressor. In this buying guide, I will share my knowledge and experience on purchasing the right AC unit capacitor 45/5 for your cooling system.

What is an AC Unit Capacitor 45/5?

An AC unit capacitor 45/5 is a dual-run capacitor that has two capacitors in one casing. The first capacitor has a capacitance of 45 microfarads (μF), while the second one has a capacitance of 5 μF. This type of capacitor is commonly used in residential air conditioning units with a single-phase compressor.

Why do you need to replace your AC unit capacitor?

Over time, the capacitor in your AC unit can wear out due to constant use and exposure to heat and humidity. A faulty or worn-out capacitor can cause your compressor to struggle to start or fail to start at all. This can result in reduced cooling efficiency, higher energy bills, and even complete breakdown of your AC unit.

What to consider when buying an AC unit capacitor 45/5?

  • Type: There are two types of capacitors: run capacitors and start capacitors. Make sure you are buying a dual-run capacitor with both run and start functions.
  • Capacity: The capacity of a capacitor is measured in microfarads (μF). It is crucial to match the capacitance rating of your old capacitor with the new one for proper functioning of your AC unit.
  • Voltage: Another important factor to consider is the voltage rating of the capacitor. It should match or exceed the voltage rating of your old one.
  • Quality: Look for high-quality capacitors from reputable brands that offer reliability and durability. A cheap, low-quality capacitor may save you money in the short term but can lead to frequent replacements and maintenance costs down the line.

Where can you buy an AC unit capacitor 45/5?

You can purchase an AC unit capacitor 45/5 from HVAC supply stores, online retailers, or directly from manufacturers. Make sure to check for warranty and return policies before making a purchase.

How to replace an old AC unit capacitor?

If you have basic knowledge about electrical wiring and have necessary tools, you can replace an old AC unit capacitor yourself. However, if you are not confident or comfortable doing it yourself, it’s best to hire a professional HVAC technician for safety reasons.

Final thoughts

Purchasing the right AC unit capacitor 45/5 is crucial for maintaining proper functioning and longevity of your air conditioning system. Consider all the factors mentioned above before making a purchase decision. Regular maintenance and timely replacement of faulty parts like capacitors can help extend the life of your AC unit, saving you money in the long run.
