It\u2019s hard to imagine surviving sizzling hot summers without being able to cool down indoors. But even if you have an HVAC system, there\u2019s always a chance of a breakdown that can leave you without cooling. This is because your AC unit has a large number of wires, components, and circuits. Normal system wear and tear can eventually lead to parts breaking down, but a unit that hasn\u2019t been serviced on a regular basis is especially prone to failures. And capacitors are one of the leading causes of breakdowns. Let\u2019s take a look at why capacitors are vital to your air conditioning unit and some common failures.<\/p>\n<h2>What Are Capacitors<\/h2>\n<p>Capacitors are essential to the electric motors in your air conditioner and they\u2019re the most common part that fails. Capacitors are a small oval, square, or cylindrical shaped device inside the AC unit. The primary job of a capacitor is to produce a bolt of electricity to start or run the compressor, blower motor, or fan motor.<\/p>\n<h2>Why Capacitors Fail<\/h2>\n<p>The number one cause of capacitor failure is from overheating. A quick visual inspection will immediately show a swollen or burst capacitor. A capacitor can overheat from four main reasons:<\/p>\n<ol>\n<li>Compressors require more energy as they age, and this additional energy can overwork a capacitor.<\/li>\n<li>A capacitor that runs for an extended period of time due to a heat wave.<\/li>\n<li>Improperly charged refrigerant level in the AC unit.<\/li>\n<li>Power surges or lightning strikes can damage a capacitor.<\/li>\n<\/ol>\n<h2>What Occurs When a Capacitor Stops Working<\/h2>\n<p>Here are some symptoms you may notice when a capacitor goes bad:<\/p>\n<ul>\n<li>The fan on the outdoor condenser unit is not spinning.<\/li>\n<li>The air conditioning unit is very hot.<\/li>\n<li>The AC starts and stops often.<\/li>\n<li>The AC unit breaker has tripped in the breaker panel.<\/li>\n<\/ul>\n<p>If you notice your home is warmer or cooler than the set thermostat temperature, this can be a sign of capacitor failure. Also, if you have a faulty capacitor, you may notice a clicking sound upon start up or a loud hum if the motor can\u2019t get going. Both sounds mean you should call your local HVAC technician for servicing.<\/p>\n<h2>Call Bruce\u2019s for HVAC Electrical Issues<\/h2>\n<p>If you\u2019re aware of any warning signs with your AC, you\u2019ll want to contact your professionals at Bruce\u2019s Air Conditioning &amp; Heating.
