Tools Professionals Use to Troubleshoot Furnace Problems

Service technicians can be your best friend when you are having problems with such things as appliances, furnaces, plumbing and other things around your home. These skilled workers are great at doing repairs quickly and efficiently in their area of expertise. Any service technician will tell you there are certain tools that they must carry on their vehicle in order to diagnose problems. It’s no different for an HVAC technician either; they too have specialty tools that help them troubleshoot furnace problems. Here are some of the most valuable diagnostic tools that HVAC technicians use.

1. Electric power meter

There is a saying among technicians in any field where they must diagnose problems on equipment that has electricity going to them to make them run; that saying is ‘where the power dies the problem lies’. This is true because the flow of electricity and the switches that make things come on and off are so important to how an appliance such as an HVAC system works. That is why every HVAC technician must carry and know how to use an electrical meter. About 80% of the time a service professional can tell where the problem is when using an electric meter to test a device that relies on electricity flow to make it work properly.

2. Gas line pressure reader

Another tool used to troubleshoot furnace problems is a gas line pressure meter. Your furnace simply will not run right if the gas pressure going to it is not sufficient enough to make a flame to produce heat. If an HVAC technician thinks the gas line may be the problem that is causing a furnace not to work, he will then use this device to check the pressure going to the burner unit. If there is not sufficient pressure the technician will know the problem is in the gas pressure line or the storage tank. If there is good pressure getting to the burner then they will take a closer look at the burner unit itself.

3. Air Conditioner Pressure Detector

Just like your gas line, the refrigerant in your air conditioner needs to be at a certain pressure in order for it to work right. Every air conditioner has specialty built connections where this testing device can be hooked up and the pressure read. If there is not enough pressure it means there is a leak or refrigerant simply needs to be added to the system.

4. Air Conditioner Leak Detection Fluid

We mentioned before that air conditioners can develop leaks. When this happens technicians apply pressure to the lines and spray the outside with a special leak detection fluid; this helps them identify exactly where the leak is and they can take steps to stop it.

Please note that in order to troubleshoot furnace problems these professionals spend many hours in training focusing on safety alone. Even if you have these devices do not attempt to use them unless you know how to do so safely. When in doubt it’s always best just to call a service professional to do the job for you.
