Before diving into the replacement process, it’s essential to understand the roles these sensors play in your AC system. AC sensors are essentially electronic eyes and ears that provide the control module with critical information. This information is then used to make adjustments and keep your AC running smoothly. Here are some of the most common types of AC sensors and their functions: Emergency Heating Repair Near Me Hvac Repair Contractor Ac Unit Replacement Near Me

• Temperature Sensors: These sensors, also known as thermistors, measure the temperature of the refrigerant, air inside the cabin, or even the outside air. They are critical for regulating the compressor, fan speeds, and the overall cooling output. The control module uses the temperature readings to determine if the system needs to cool more, less, or maintain the current temperature. 24 Hour Emergency Heating Service Ac Repair Companies Hvac Air Conditioning Service

• Pressure Sensors: Pressure sensors monitor the pressure of the refrigerant within the AC system. They are crucial for preventing overpressure and underpressure conditions that can damage the compressor or reduce cooling efficiency. These sensors provide data to the control module, which then adjusts the compressor’s operation to maintain the correct pressure range.

• Evaporator Temperature Sensors: Located within the evaporator core (the part of the AC system that cools the air inside the car), these sensors measure the temperature of the evaporator. This information is used to prevent the evaporator from freezing over, which can block airflow and reduce cooling performance. 24 Hvac Service Near Me 24 7 Hvac Near Me Heating Cooling Repair

• Ambient Air Temperature (AAT) Sensor: This sensor measures the temperature of the outside air. The control module uses this information to adjust the AC’s performance based on the ambient conditions. 24 Hour Emergency Air Conditioning Service Near Me Ac Repair Contractor Emergency Hvac Service Near Me

• Refrigerant Level Sensors: Some systems have refrigerant level sensors that monitor the amount of refrigerant in the system. If the refrigerant level is too low, the sensor will trigger a warning or shut down the AC system to prevent damage.
