Feeling cold and hot is expected; however, conditions are sometimes unbearable. Since you can't abandon your home because of this, you can use an HVAC thermostat. The HVAC thermostat (a complete heating, ventilation and air-conditioning system) helps to regulate the indoor temperature.
There are two types of thermostats with different energization methods: line voltage and low voltage. Low-pressure thermostats use electricity, gas, or oil. In contrast, a line voltage thermostat uses the current flowing from the thermostat to the heater in a single heating system. Like any electronic product, these essential electronic products sometimes fail. Reading this publication will help you understand the signs that the HVAC system needs to be replaced.
Manufacturers make electronic products such as thermostats have a long service life, while HVAC thermostats have a service life of about ten years. Although it can work for centuries, it depends on the model, brand, and how you handle it. But knowing that it may start to show mechanical or functional problems ten years later would help.
If you suspect that your thermostat is not working properly, you can check it by following the steps below:
You will first shut down the HVAC system. If it has a switch, you can do this by turning it off. In a system without this feature, you will have to cut off the power to the circuit breaker box. You should find a circuit pole called a marker stove or HVAC.
Use a screwdriver to remove the thermostat cover to access internal parts and wires. In some thermostats, you must remove the entire lid.
After turning on the system, you should find that the wires have been screwed to the marked terminals. This will help to take pictures of the markers to avoid confusion.
Carefully unscrew the wires and then insulate them. If you find more wires than red and white. Using pliers, twist the two wires at the bare end to connect them. During this time, please make sure that they do not touch any uninsulated wires.
Then, you will turn on the system according to how you turned it off. If the blower starts to work and the furnace ignites without a thermostat connected, the system is malfunctioning.
After running the test, turn off the power and untie the wires you twisted together. If you see fit, you can continue to test the connection with other cables (if there are more than two).
If you are inconvenient and unable to test the system yourself, some signs should help you understand if the HVAC thermostat is malfunctioning.
Turn on and off by yourself
When the system fails, HVAC stops responding to the thermostat's temperature increase or decrease signal. When this happens, the HVAC will continue to turn on and off on its own.
When your HVAC system wears out and malfunctions, you will notice that you will receive abnormal bills for energy usage. The high cost comes from the multi-function, which forces the HVAC workload to exceed expectations.
The thermostat uses readings to control the heat level in the room, and when it fails, you will see false readings on its display. To confirm the temperature, you can use an indoor thermometer.
A short period refers to a situation where the system shuts down before the room temperature is properly controlled. If you notice this, you should be ready to replace it.
When you need to replace thermostats, you will find different categories based on their functions. These categories include:
If you want your home to benefit you, you should use electronic devices such as thermostats to adjust the temperature. However, you should pay attention to check whether the system is operating well. If you don't do this, it may bring you huge energy bills and make your home disadvantaged. Use this guide to learn when you need to replace the thermostat.
