Common Problems & Troubleshooting of HVAC Thermostat

Our HVAC systems control our comfort, and thermostats control our HVAC systems. For our furnace and air conditioners to function at the right temperature, your thermostat has to be error-free. Thermostats are devices that control, regulate, and maintain the temperature and the flow of hot or cold air.

These devices are installed with your furnace installation in Irvine, CA. The position of your thermostat plays an important role in the functioning of your furnace. Problems in your thermostat can make you worry about your HVAC and lead to an unnecessary furnace repair in Irvine, CA.

3 Common Thermostat Problems and Its Troubleshooting

While getting your furnace installation in Irvine, CA, done, ensure to ask your technician about all the possible thermostat issues. It helps you differentiate the causes of your furnace problems and provides you with guidance to schedule the right service. Here are 3 common and most experienced thermostat problems and how to troubleshoot them:

  • The Thermostat is Set on Incorrect Temperature

    If your furnace is not providing enough heat, your thermostat could be the problem. For adequate heating, your thermostat has to be set at the right temperature.

    Troubleshooting: Check if your thermostat is switched ‘ON’ and on the right temperature of 20-22 degrees. Also, the dial should be set on either COOL or HEAT.

  • Continuous Running of HVAC or Short Cycling

    Another thermostat issue could be non-stop HVAC operation or short cycling. Your furnace keeps on running without providing sufficient heat. It consumes extreme energy and spikes the energy bills. The possible reasons for this problem could be a poorly regulated anticipator, off-kilter, or dirt accumulation near the thermostat.

    Troubleshooting: To solve this issue, begin with cleaning the thermostat. Next, you can try moving the anticipator dial towards the word “longer”, one point at a time. This could help in lengthening the HVAC cycle. If none of this works, it is time for your thermostat to get upgraded to a programmable version.

  • Your HVAC System Stops Working Without a Warning

    A faulty thermostat can restrict the functioning of your HVAC. The reason for this problem could be the supply of energy, either through batteries or hardwiring. Dirt accumulation or corroded wiring can obstruct the electric current, shutting down the thermostat and the HVAC system.

    Troubleshooting: Try changing the batteries and checking the circuit breaker for a blown fuse or tripping the breaker. Look for loose wiring, dust inside the breaker, and terminal screws. All of these could be hampering the energy supply. If fixing all of the above issues does not fix the thermostat, consider replacing the device.

    To avoid all kinds of thermostat problems, keep your thermostat clean and keep a check on its wiring. Contact your technician if you find any discrepancies in your HVAC and the thermostat. Being informed about your HVAC is always the right option.
