Several mistakes fail an HVAC system. First, most of the technicians perform the test without proper knowledge of equipment.- First of all, if there is any fuse box, you must check that one. Unfortunately, most of the HVAC technicians forget to check the fuses.
- When it comes to air conditioning systems, people try to focus on airflow, but there is an equal chance of circuitry failure.
- Voltages are the crucial points. Always check the voltage because most of the time, over voltage and under voltage damages the system.
- Temperature sensors are the main feedback of your HVAC system. Usually, nobody focuses on thermostats or RTDs
