Is it OK to run an AC with a bad capacitor?

If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.</p></div>

"Vivint is the worst company I have ever done business with. Having Vivint is a condition on my lease and, if it wasn't, I would quit in a minute. The company is so cheap about replacing malfunctioning equipment. My front door lock doesn't work and I have been working on getting a replacement for over a month. Still no luck. An appointment is not an appointment but I rough guideline to when someone may or may not show up. There are a lot of alarm companies and I could never recommend Vivint."

Heating and Air Conditioning questions, answered by experts

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork.

When the capacitor fails, the AC unit can’t operate at all. The most common sign is the thermostat forcing the blower to turn on, but it only circulates room-temperature air. The AC unit also won’t make any noise or indication that it’s on. Sometimes, the compressor might hum as it attempts to work, but without any results.

Before a full shutdown, a faulty capacitor can cause your AC to struggle while turning on. The unit might also shut down in the middle of a cooling cycle.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.
