HVAC Clamp Meter

There are several common electrical problems that each AC service tech or maintenance technician faces. A short list of them includes: improper voltage, blown capacitor, or a faulty thermostat. An HVAC service technician needs a good clamp meter to diagnose these issues.

If there is improper voltage the AC system will not operate as designed. Low voltage means there will not be enough power for the system to start. This problem is called a “hard start”, in which a unit starts slow due to insufficient voltage. In such a case the fan may not provide sufficient air flow to the coils and the pipes may even freeze.

Capacitors store the electricity required for a compressor to work. If a capacitor is blown, the compressor won’t work. HVAC technicians need to figure out the reasons for a bad capacitor, so they need a clamp meter to troubleshoot problems to avoid causing a new capacitor to go bad.

Problems with thermostat wiring are often the cause of the improper functioning of thermostats. Wires could be shorted, open or damaged in some way. A good HVAC clamp meter will test those issues before a new thermostat is installed.
