AC repair in Clermont

Florida has a reputation for having lots of sun, heat, and humidity, so many residents rely on air conditioners to stay cool. Unfortunately, these systems rely on several essential components to work correctly, including the capacitor. Like other HVAC parts, they’ll eventually break down, but how long do AC capacitors last? 

A failing capacitor is a good reason to seek professional AC repair in Clermont, FL. As one of the community’s top HVAC contractors, our Egberts Electric and Air Conditioning professionals have ample experience dealing with failing air conditioning capacitors. Here’s what our team has to say about the function and lifespan of this essential cooling system component. 

Air Conditioner Capacitors: What Are They?

Cooling unit capacitors are small cylinder-like components that connect to the compressor and store electricity, almost like a battery. When the HVAC system runs, the capacitor provides additional energy to start the motor. If this part fails for any reason, the air conditioner will struggle to function; it likely won’t turn on and circulate conditioned air.

The Average Lifespan of an Air Conditioning Capacitor in Clermont

How long do AC capacitors last? The general lifespan is anywhere from five to 20 years.

The range is so wide because multiple factors contribute to how long the component can function properly, such as location and wear and tear. For instance, Clermont residents can expect to replace their capacitors every 10 to 15 years due to Florida’s humidity and the constant need for chilled indoor air. 

Four Common Reasons for Capacitor Failure 

Your air conditioner can stop working for many reasons. A failing capacitor is just one of them. So if five to 20 years is the answer to “How long do AC capacitors last?” what could cause the equipment to fail prematurely?

Here are four reasons this vital cooling system part fails in Clermont and neighboring communities.

1. Poor Installation

When HVAC technicians fail to properly install cooling systems, it affects the equipment’s performance and efficiency. The same goes for capacitor installations. Incorrect installation can cause premature failure.

2. Power Surges

These essential HVAC parts can handle receiving, storing, and sending electrical currents to cooling system motors, but too much power isn’t good for them. Power surges due to lightning strikes or electrical grid fluctuations can fry capacitors, rendering them unusable. 

3. Excessive Usage

As with any AC unit component, using a capacitor too often will shorten its lifespan. In other words, if you rely heavily on your air conditioning system to cool your Clermont property, you’ll likely need to replace the capacitor sooner rather than later.

4. A Lack of Maintenance

The best way to maximize the efficiency of a capacitor is to maintain it regularly. Periodic cleanings and inspections to look for signs of wear or damage can keep it running efficiently for longer.
