Frequently Asked Questions (FAQs)
1. What is a AC thermostatic switch?
Thermostats regulate the temperature of liquid in a tank, or in conjuction with air conditioning units to monitor the air in a room or system. The thermostat simply switches the system off or on whenever necessary so that a constant temperature can be maintained.
2. Which type of temperature sensor is used in air conditioners?
A thermostat sensor is normally close to the evaporator coil inside the air conditioning unit. As the air passes over the sensor, it checks the current temperature of the air and compares it to the desired temperature.
3. Can you switch back and forth between AC and heat?
Many homeowners are concerned about breaking or wearing out the heating and cooling components of their HVAC system by switching back and forth. However, if done properly, this shouldn't cause any problems.
4. Where is the AC evaporator temperature sensor?
It's commonly located on the passenger side on most cars, trucks, and SUV's. Most of the time, the sensor is located towards the rear of the condenser (or closer to the rear of the vehicle as opposed to the front end).
