HOW YOUR AC CAPACITOR WORKS AND WHY IT MATTERS
Your air conditioner relies on a small but essential component called the capacitor to start and run its motors. Without a functioning capacitor, your compressor and fan motors cannot engage, which means your system will struggle to cool your home or stop working entirely.
Capacitors store and release electrical energy in controlled bursts. There are two types in most residential AC systems: the start capacitor, which gives the compressor motor the initial jolt it needs to turn on, and the run capacitor, which keeps the motor running at a consistent speed.
When a capacitor begins to fail, its effects appear quickly. Your AC may take longer to start, cycle on and off frequently, or produce warm air instead of cool. In Lexington's hot and humid summers, a failing capacitor can leave your family without reliable cooling at the worst possible time.

Warning Signs of a Failing AC Capacitor
Catching a capacitor problem early can prevent a full system breakdown. Watch for these common warning signs that your AC capacitor may need to be replaced.
AC takes a long time to start after the thermostat kicks on
Humming noise from the outdoor unit without the fan spinning
The system shuts off on its own before reaching the set temperature
Warm air is blowing from the vents even though the system is running
Higher-than-normal energy bills with no change in usage
Visible swelling or leaking on the capacitor itself
If you notice any of these signs, it is important to have a qualified technician inspect and test your capacitor before the issue worsens. A failing capacitor that goes unaddressed can put extra strain on your compressor, which is a far more expensive repair.
What Causes AC Capacitors to Fail
Heat is the number one enemy of AC capacitors. Lexington summers regularly push temperatures into the 90s, and your outdoor condenser unit absorbs that heat all season long. Over time, prolonged heat exposure degrades the capacitor's internal components and reduces its ability to hold a charge.
Power surges from storms or grid fluctuations can also instantly damage capacitors. Electrical spikes overload the capacitor and can cause it to bulge, leak, or fail outright. Homes in areas with older electrical infrastructure may be more susceptible to this kind of damage.
Normal wear and tear plays a role, too. Most capacitors last between 10 and 20 years, depending on usage and conditions. If your AC system is more than a decade old and has never had a capacitor replacement, it may be operating on borrowed time.

OUR AC CAPACITOR REPLACEMENT PROCESS
When you call Watson Heating & Air for a capacitor replacement, we make the process straightforward from start to finish. Our technician arrives with a fully stocked truck, so most replacements are completed in a single visit.
We begin with a full diagnostic of your AC system to confirm the capacitor is the source of the problem. Our technician tests the capacitor with a multimeter to check its charge and compares it to the manufacturer's specifications for your unit. If the capacitor is out of range, we recommend replacement.
Once confirmed, we remove the failed capacitor and install a new one matched to your system's exact specifications. After installation, we test the entire system to verify that the compressor and fan motors start and run correctly. You get upfront pricing before any work begins, so there are no surprises on the bill.
