Speedy air conditioning repair is a requirement for the job in places like Athens, GA, where the summer temperatures can be unbearable. Experts learn how to diagnose problems quickly, the better to get peopleâ€™s air conditioners up and running again before the heat becomes too much. Since central air conditioning systems rely on electrical power to function, that means a service technician needs to be able to test the voltage in order to properly diagnose the problem. So how does a technician do that? The same way an electrician might diagnose a similar problem anywhere in the home.
The electrical power required to run a central air conditioner is quite large: up for 5,000 watts on start-up, with another 3,000 watts per hour for your average-sized unit. Most air conditioners use a dedicated circuit, either 220-volt or 240-volt, to function. That powers components such as the fan motor and compressor motor, which are an important part of the unitâ€™s cooling cycle. Proper voltage is important; if you use too much power, the unit wastes electricity and may risk an overload; it you use too little, the unit will either fail to function completely or function far less efficiently than it should.
Most service electricians use a multimeter or a volt meter to determine the voltage of an AC unit. The devices contain two wires, one ground wire (usually black) and one â€śhotâ€ť wire (usually red). The hot wire is connected to the circuit you want to test and the ground wire is placed on a grounded piece of metal. The technician then sets a dial to measure a specific level of voltage and the device informs him or her of the results. Some multimeters do this automatically and no dial function is needed.
