What Is “Hard Starting” in an Air Conditioner?

One of the more common malfunctions that can occur in an air conditioning system (as well as a heat pump) is “hard starting.” This is when the AC at start-up indicates it is having trouble: it will stutter and make clicking or grinding noises, then run only a brief time before shutting off again. It’s similar to a car’s engine having difficulty turning on during the winter, although what’s occurring in an air conditioner is different.

A number of issues inside an AC can account for hard starting. Whatever the root cause, it’s a serious problem that requires repair professionals to investigate and fix it. Your air conditioning may continue to run and provide you with the comfort level you want, but hard starting means that it will probably not continue to do so for much longer, and the system will drain excess energy and waste money until the full breakdown at last occurs. If the inevitable does happen call for professional repairs for your air conditioning in Savannah, GA.

Reasons for hard starting

Hard starting often arises from an electrical issue, particularly a problem in the start capacitor. The start capacitor sends electrical voltage to the motor that runs the compressor in order to start it up. If the capacitor begins to fail, the air conditioner will have a harder time starting up. If you hear a clicking noise when the AC hard starts, the capacitor is likely at fault and will need to have a repair technician replace it.

Another possible electrical issue for hard starting is loose wires or a bad start relay. Low line voltage is another possibility. Sometimes a repair technician can add a “hard start kit,” which is a capacitor that gives extra voltage to the compressor motor. Not all AC models will take a hard start kit.

A more troubling problem could be in the compressor itself. A compressor that is tight or seized because of stress and wear and tear will create hard start issues; often, a hard start kit can resolve compressor difficulties. The compressor may also be near the end of its life, in which case the whole AC system is approaching the end of its service life and will require a replacement. (Full compressor failure usually indicates a need for a new air conditioner.) If repair technicians cannot get the compressor parts moving again or solve the issue with a hard start kit, he or she will advise you about whether replacement is your best option.

Do not attempt to tamper with a hard starting air conditioning system on your own, or attempt to fix the issue by installing larger fuses or bypassing fuses: these create major fire hazards. Call for expert technicians. For repairs for your air conditioning in Savannah, GA to solve hard starting, contact AAction Air.
