What is +,- Temperature, and how to work

Question

Accepted Answer

The +,- temperature is the difference between the actual temperature and the desired temperature. HVAC technicians work to adjust the temperature accordingly.

The +,- temperature is also known as the temperature differential.
It is calculated by subtracting the desired temperature from the actual temperature.
HVAC technicians use this measurement to adjust the heating or cooling system to achieve the desired temperature.
For example, if the desired temperature is 72°F and the actual temperature is 75°F, the +,- temperature is -3°F.
Technicians may need to adjust the thermostat, check for leaks or blockages in the system, or add or remove refrigerant to achieve the desired temperature.
