An HVAC capacitor is a small but essential part of your HVAC system. It works like a battery, storing energy that helps power your system’s motors. These motors are necessary for important functions such as cooling your home in the summer or warming it in the winter. However, capacitors are also prone to failure like other HVAC components, and this occurs due to various factors.
In this post, Cafco Services explores the common causes of HVAC capacitor failure, the warning signs to look out for, and the impact of this problem on your home’s comfort and efficiency.
Just like other parts of your HVAC system, the capacitor can wear out over time. As it ages, it becomes more likely to fail, especially if it has been subjected to extreme stress or usage.
Capacitors are located in the outdoor unit of your system, where they can easily overheat. If a capacitor gets too hot, it can cause the protective oil inside to leak out, leading to failure.
If your system is subjected to a voltage that’s either too high or too low, the capacitor can become damaged, potentially leading to failure.
When your HVAC system is not properly installed or maintained, its capacitors and other crucial components are forced to work harder. Professional installation by HVAC installation companies is key to preventing HVAC capacitor failure. A proper installation can also ensure that your system is equipped with the right capacitor.
Regular HVAC repair and maintenance can also stop capacitor failure before it happens. These preventive measures can catch small issues before they become larger, more expensive problems.
If your HVAC capacitor isn’t working properly, you may notice some of the following indications:
Unusual buzzing or humming noises
The fan or motor failing to run at full power
Frequent cycling of the motor
The fan’s speed varies randomly
Excessive heat buildup
Poor cooling or reduced efficiency
If your HVAC system is experiencing any of these symptoms, it may be a sign that the capacitor is failing. Enlist a professional heating and air conditioning repair service right away for assistance.
A malfunctioning capacitor can affect your HVAC unit’s performance by hindering the cooling process. Bad capacitors can also damage other system components, resulting in uncomfortable temperatures and the need for expensive repairs or replacements.
